LCCC Still Meeting at BWW in Brighton - and Stockfish is the Best Chess Player in the World

 

Who's on f6?

Older chess players will catch the joke.

LCCC met again at the Buffalo Wild Wings in Brighton, MI, with 12 players in attendance. Your humble scribe could not attend battling a head cold (and no, not Covid). But the Club Secretary Paul filled in as host and made sure everyone had a good time.

We had some new faces join us – Jim and Matt, as well as two old faces (that means players that used to attend the club. But in this case they are old faces also) – Dave and James. Welcome all four of you.

LCCC will be meeting next on Monday June 21 at 4pm at the same Buffalo Wild Wings in Brighton, MI in the Green Oak Mall just off of US-23 at the Lee Road Exit. See you then.

Practice must start as over the board chess tournaments seem to be starting back up! An email announcement let me know that the Michigan Open Chess Tournament will be held again!

The Michigan Open will be held at the Radisson Hotel Lansing from Friday September 3 thru Monday September 6. There will be a 3-day and a 4-day schedule, and two sections – the Open and the Reserve.

This is great news and visit the Michigan Chess Association website or the United States Chess Federation website for details on how to enter.

Now for a partial reprint of information from an article that appeared the US Chess magazine in March 2021 by John Hartmann, along with some commentary.

STOCKFISH retains the title of the best chess computer program.

The tournament is called the Top Chess Engine Championship or TCEC. Stockfish won the 20th version of the tournament and has won it for the third straight year.

Stockfish beat Leela 53 – 47 over a 100 game match, winning 14 games and losing 8, the rest ending in draws, so a 14 – 8 – 78 record.

Leela upended Stockfish four years ago when it arrived on the computer chess world with it’s new ‘neutral network-based intelligence’ and beating the traditional ‘alpha-beta driven’ chess engines.

Now for drumroll………………Stockfish top addition has a rating of 3601!

Wood pusher Leela comes in at a pathetic 3586.

Magnus Carlsen, the current best human player on the planet has a rating of 2847 at this writing.

To give you a perspective as to how great this spread is, players not within 100 points of Carlsen have literally no chance of being him, and maybe only a 25% of even drawing.

I know back here where us mere mortals play chess, a 100-point difference is rating usually translates into about a 55-35 and 10 draws difference in results over 100 games. At that top level, a 100 point difference would probably look like this 50 – 5 and  45 draws.

This leads to the logical question – will programs ever solve chess and ruin the game for humans?

This humble scribe says no. Not any more than the automobile or airplane eliminated running competitions for humans. We will always know that our brains will never catch up to the calculating speed, strength, stamina and complete lack of emotion during the process as computers, but …..after all…..we still created those programs and machines.

Humans still win.

How to Lose at Chess - and 051021 LCCC Meeting Had Twelve!

 


Twelve strong for our meeting at the Buffalo Wild Wings in Brighton, MI on Monday May 10, 2021. 

Hope to see you there for the next meeting, Monday, May 24, 2021 at 4pm.

Now for the article:

I stared at the chessboard in front of me. It's hopeless now. Even against this opponent who allegedly is rated 400 points lower than myself. But, this is after all, the US Open. Not too many players entered this tournament after 'padding' their rating on the high side. 

Doesn't matter who is beating you anyway. It hurts when you know it's time to resign. It always hurts, at least a little bit.

Even though my five previous losses in the last seven had numbed me a little from the usual pain of tournament chess losses, this one was going to really send me into a chess depression. This loss was going to be even more devastating to my rating as it was going to be to my ego. My chess ego was already approaching zero, and dropping rapidly.

I turned over my king and shook my very young opponent's hand and told him "Nice game. You played well." Six losses and only two wins, with one round to go. And that round was one I no longer had any desire to play in. As I stumbled to my room, I wondered how it all went so wrong. After all, I tied for first in a pre-tournament US Open Quad - two wins and the dreaded 'GM draw' in the last round to clinch the tie for first. 

But now, in the main tournament, I had two wins against very weak opponents and six losses, with four of those losses against opponents I could expect to beat or should beat. I had no confidence I could beat the next 'lower rated' player I would probably be paired with. It was going to be a very long 500 mile drive home as it was. A loss in the last round might have me looking for taking a short cut into Lake Michigan from Wisconsin instead of driving around it!

US Open rounds are played in the evening. But falling asleep after this loss was out of the question. So after watching TV until I could not keep my eyes open, and getting up only in time for a late lunch, it was time to prepare for the last round.

That is when the gremlins of negativity, laziness and self pity started talking to me in my head. "Prepare? What for? You will probably have a real easy opponent that you will finish off quickly. And even if you draw or even lose, so what? You are out of any prizes anyway. Better to finish the game early and enjoy the last night of your chess vacation."

As I heard the gremlins, it occurred to me that I had heard some of this 'out of the prizes' chatter the last round. Then I thought back and noticed that my last two losses may have had a lot of moves, but I was done awfully early. 

I pulled out my scoresheets and played over every one of my games from this tournament. Even the Quad games. I quickly noticed two things in my last four games. One - I was 'forcing' play when the positions did not warrant it. Two - I was using less and less of my clock as the tournament went on.

In other words, I stopped working. I did not knowingly think I had, but I had started playing chess - in the US Open - almost like a casual rapid or blitz game! I completely deserved the thrashing I was receiving. I got lazy!

I looked as some of the moves I made in the previous games and wondered who had poisoned my ice water. Did I forget there are more than 16 squares on the board, and looking over the entire board might be of benefit? Or that when your opponent moves one of his pieces, you may want to consider why he did that? How about castling BEFORE blowing open the center of the board for no apparent reason?

The 'gremlins' had it right. I HAD gone on vacation - during a chess tournament!

The lesson here is that when you lose, learn something from it! Don't start a pity party where the only attendee will be you. Turn losses into a learning tool. Learn from your mistakes. So don't be sad.

And of course winning is not learning. You just did not make as many mistakes as your opponent did. So don't be happy. 

Why was it again, that we love to play chess?

PS: I won the last round. Not so much because of my 'prep'. But because my opponent was on vacation even more than I was.

Endgames are Tricky! - And LCCC Meetings 041221 and 042621 Were Fun!

 Sorry for the delay in posting. Lots going on in life that gets in the way of chess blogging.

Anyway, we had nine members at the Monday April 26 meeting and we grew to our highest total since the re-start to 12 members! Welcome all!

Our next meeting is Monday May 10th at 4pm until at least 9pm. So feel free to stop by. 

We continue - as a club - to move up the Chess .com standings in the club rankings. We are nearing 500 wins as a club! Most clubs never get near that number. 

If you like playing chess in a way that is basically - postal chess on Chess .com, then come join the Livingston County Chess Club on Chess .com and then sign up for the Team Matches as they become available. We don't care if you win or lose - just don't forfiet on time.

Also, if you are on the LCCC on Chess .com and are not playing in any Daily tournaments for us, don't be surprised if you are booted out of the club on that site. We cannot have players listed on our club that do not play in our Daily matches occasionally. The main reason is that it makes our club look bigger than we are, but also your rating may inflate our Team rating. Both factors may stop some teams from challenging us or accepting our challenges. You don't have to play in them all or even half of them. But some participation is required to stay on the on-line club on Chess .com.

 Why no one would play at least a few games this way is a mystery to me. To have a few games going that you have 3 days to make a move seems fun and relaxing to me. And the fact you can play or analyze from your phone, takes away just about any excuse I can think of.

Now for the endgame magic!


White to move and win. The material is even but White has a huge positional lead says Igor3000. But how?

Very  tricky endgame here. White must somehow stop the more advanced a-pawn of Black's and at the same time try to promote his only chance to win - his own g-pawn.

First things first!

1. Bb1      

Needed to stop the a-pawn. No other move wins. 

1. Bc2+ makes the position even.

1. g6? will let Black queen his pawn first and is losing for White! 

1. ......          f4

"Passed pawns must be pushed." Understandable for Black. The f-pawn is the only pawn White cannot stop without wasting another move. But now what does White do?

2.  Kc5!        .......

Threatening mate in one move with Bc2, so Black must delay his pawn advance by another move.

2. ......           Kb3

3. g6             Kb2

Black must remove the bishop in order to queen his pawn. But this takes too much time.

4. g7             Kxb1

5. g8 =Q       a2

White's queen must first stop the a-pawn and at the same time either sweep up all the Black pawns or set a mate trap by allowing a queened pawn.

6. Qg1=        Kb2

7.  Qd4+        Kb1

8. Qd3+         Kb2

9. Qb5+         Kc2  (or even if Ka1, White's next move is the same)

10. Qxa5        Kb2

11. Qd2+       Kb1

12. Kb4         d4   (12. ....a8=Q is a mating net with 13. Kb3 and mate soon to follow.)

13. Qd1+      Kb2

14. Qb3+      Kc1  (14. ...Ka1 allows 15. Kc4, 16. Kxd4, 17. Kc3 and 18. Qb2++)

15. Qxa2       Kd1

16. Qf2          Kc1

17.  Kc4        f3    (Black is trapped on the back rank and his pawns won't make it to the finish line.)

18. Kxd4       Kb2

19. Kc3          Ka1

20. Qb2++

032921 LCCC Night of Chess a Sucess; And Meet Erich Eliskases


LCCC met again at the Buffalo Wild Wings in Brighton, MI. It was another nice round of over the board chess and great conversation, with 8 players in attendance.

We were graced with the presence of a past member of our club that has moved to the east side of the state and cannot make the commute anymore. He is none other than Jason Morris, an Expert and writer for the Michigan Chess Magazine.

Jason played some games with us and reviewed some grandmaster games with our members. Thanks Jason!

Erich Eliskases (picture on left) is another great chess player you never heard of. He is the only man to represent 3 different countries in the Chess Olympiads (thru no fault of his own – more on that later). He also had tournament victories over the likes of Max Euwe, Jose Capablanca and …..drumroll…Bobby Fischer! His record against all three was (3-3), (2-2) and (1-1) respectively. Impressive.

Born in Innsbruck, Austria in 1913 Erich learned to play chess completely by chance at the age of twelve. And at the age of nineteen, he won a ten-game match against World Championship contender Rudolf Speilmann 5.5 to 4.5, losing the final meaningless game. Eliskases had already won the match winning games 2, 7 and 9 (odd numbered games with Black).

There were discussions of the young Erich to play Alexander Alekhine for the World Chess Championship, but political issues soon got in the way. Go figure. Eliskases did represent Austria in the Chess Olympiads during the early 1930’s.

Young Erich Eliskases saw what was happening in Europe and left for South America in 1939. He did play for Germany in the 1939 Buenos Aires Chess Olympiad. When World War II broke out, Erich decided to stay put.

Erich moved back and forth between Brazil and Argentina, finally becoming a naturalized Argentine citizen and representing his new country in the Chess Olympiads of 1952, 1958, 1960 and 1964. He made his living as a chess instructor.

Eliskases was a strong correspondence player and an endgame wizard. His defeat of Capablanca was in an endgame – and Capablanca is regarded as the best endgame player of all the greats!

Erich Eliskases died in Cordoba, Argentina in 1997 at the age of 83.

Here is game #7 of his match with Rudolf Speilmann, Litz, Austria, January, 1932.

White: Speilmann – Black: Eliskases, Queen’s Gambit Declined; Semi-Slav without Nf6 (D31)

1.     d4          d5

2.     Nf3          e6

3.     c4          c6

4.     Nc3        dxc4

5.     e4          b5

6.     e5          Bb7

7.     Be2        Ne7

8.     Ne4        Nd5

9.     O-O        Nd7

10.  Nfg5       Be7

11.  f4?          g6?!

White’s 11th move is the last “book” move but both Igor3000 (-1) and Stockfish12 (-1.9) say this move is a real stinker. Correct was 11. b3, putting pressure on Black’s queen-side pawns. Black’s reply shows why f4 was playable in those days. Black weakens his king-side (and we assume his castling side) for no reason. Castling was best here (-.6). But as we will see, Black never needs to.

Noted chess author and annotator Fred Reinfeld said, “Spielmann is playing the opening in an aggressive fashion attempting to get an attack at all costs. The manner in which his young opponent defends himself is highly instructive.”

            12, f5 ?!         ………

As was Speilmann’s lifelong chess weakness…..this is too aggressive too soon. Remember pawn advances cannot be retreated if incorrect. 12. Rf3 was best. (-.9).

12.  …….          exf5

13.  e6             fxe6

14.  Nxe6        Qb6

15.  a4?           ........


Fred Reinfeld said of White's #15 move; “This desperate move is the beginning of an extremely ingenious combination……which is defeated by a still finer counter-combination.”

The chess engines see all and have White lost at (-2.6) and suggests instead for White 15. Rxf5, c5 16. Ng7+, Kd8 17. Rf2, cxd4 18. Qxd4 and still losing (-1) but still playable.  Eliskases sees that a4 is wrong also.

       15. ......          fxe4

       16.  a5            Qa6

       17.  Qc2 ?       N7f6 ?  (!)

Another blunder by White (-3.75).  17. Ng7+ was needed. But Black ‘blunders’ back - sort of.

It is interesting here – in this position - to note that this is the type if situation where chess cheats get caught.

Fred Reinfeld was considered one of the very best chess annotators back in the days before chess engines. He gave 17… N7f7 an exclamation point! He states, “The alternative 17. …..c5 would lead to all sorts of complications, whereas the text move forces White’s hand.” 

The only problem is Fred, is that c5 is the real best and crushing move. The computers can wander thru the analysis maze faster and with no emotional strain or drain.

In other words, Eliskases made the ‘human’ move to victory by not muddying the waters (- 1.7) Computers have no such fear at a million moves per second analysis.

18.  Rxf6?        Bxf6

19.  Qxe4         Kf7 !

Reinfeld exclaims, “A remarkable position! Black must lose the Queen, and yet has a won game!” (-3.4) Your humble scribe agrees. The type of position only GMs are not afraid to play.

20.  Nc5          Rae8

21.  Qf3           Rxe2!

22.  Nxa6        Re1+

23.  Kf2          Rhe8!

(-4.5) Reinfeld: “This turns out to be even more powerful than 23. …..Rxc1 24. Rxc1, Bxa6.” (-1.3)

24.  Nc5          Bc8

25.  b4            Kg8

Reinfeld: “This makes the hostile c-pawn very strong, but how else is White able to free his bishop?” (-7.4)

26.  Bb2          R1e3

27.  Qd1          c3

28.  Bc1          c2

29.  Qxc2        Re2+

30.  Qxe2        Bxd4+

31.  Be3          Rxe3

32.  Qf1          Ra3+

White resigns

This Coming Monday at BWW! And Why Chess is Always Facinating

 See you at Buffalo Wild Wings in Brighton this Monday March 29 at 4pm until whenever. The basketball tournament on TV may make us have to abandon our tables if they get too crowded......or we may have to order more bee,..eh, ......food. That's right......food!

 Here is a game which shows why chess is the greatest game known to man. No one can make this stuff up!

It was GM Vladimir Kramnik vs GM Mikhail Ulybin in Chalkidiki, Greece in 1992. Here is the position:


   Here are the annotator Rudy Blumenfeld's notes. My notes will be in ( ).

   The White rook at a7 is inside Black's        position and the dark-square bishop has a great diagonal. But there is no coordination between the White pieces. However, things are about to change quickly!

    36. g5 !!

   (When I saw the double !!, I had to have Igor3000 take a look at this to see if Kramink had found a 'computer' move, as he is certainly capable of computer-like chess genius. 

Well, Kramink did not make the best move according to Igor - who studied the position for 15 minutes and going eleven and half moves deep. Igor says 36. Bg2 was best giving White a .89 of a pawn advantage.

Igor then informed me that Kramnik's move was not the second best move......Bh1 was ....giving White a .88 pawn advantage. Well where was g5? After all, that move got a 2x ! by the annotator. Granted, maybe Rudy did not use a computer or the computers available to chess writers were not very strong in 1992. But I had to see how far down 'g5' was on Igor's totem pole of best moves.

Well, it was not 3rd as Rb1 gave White a .86 pawn advantage. And meanwhile, Igor has been looking a million moves deep a second for 20 minutes now!

And 'g5' was not the 4th, 5th, 6th or 7th best move either as Rd4, Kf1, Rd5 and Ba1 all put White at a .82 of a pawn advantage.

It was not even 8th as Ke1 still left White with a .81 advantage.

THIS is why chess is the greatest game ever! So many possible moves. All good, all still winning, all perfectly fine for White, and all will send Black on a different mission to find his best reply. You just have to LOVE this game (and it is a gift from above) of chess!

At #9 is 'g5' with only a .79 advantage for White. Kramnik did have a plan for growing his advantage to victory, and it is a very 'human' plan of using the open h-file for his rooks. If only his opponent will blunder just a little, a win is possible. 

And this is all the side with the slight advantage can do, is to keep making solid and forcing moves and wait for your opponent to slip up, even ever so slightly. 

Or, do what I usually do, and toss the advantage out the window and then beg for a draw!)

   36.  .......          hxg5

   37.  hxg5         Nxg5?!

(The first little sidestep by Black. The text move looks obvious to mere mortals, but 37. ....Kg8 was preferable - 38. Rd5, Kf8  39. Bg2, Rc8 and the .79 disadvantage does not grow to +1.01, a full pawn positional advantage.)

   38. Bc6          Rc8

   39. Rh1          Kg8

By threatening mate, White brings the rook along the open file with tempo (a move gainer).

   40. Raa1         Nce6?

(Uh-oh for Black. Again the most natural move as you would want to leave the one Knight in front of your embattled King, but 40. ...Nge6 was better. Now White has a +2 pawn positional advantage. And 40. .....f6 was even worse for Black. Kramnik needs no more help to get this win.)

   41. Rh4 ?!        f6             (41. Rag1 was better, but White still holds a +1.6 advantage)

Now the diagonal c4-g8 has been weakened.

   42. Rg1         Kf7

   43. Bd5         Ke8

   44. Rh8+       Nf8

   45. f4            Nge6

   46. Kf3          f5

   47. Rg6         Nc5

   48. Bxg7       Rf7

   49. Bxf8       Black resigns

LCCC is Back Playing Chess Live! Stop By! Oh, And Drawing Conclusions


Another successful chess evening at the Buffalo Wild Wings in Brighton, Michigan at the Green Oak Village Place Mall. We started at 4pm and by the 7pm had 8 players involved in 4 games! Not a bad number for our 3rd attempt at starting live chess back up. We concluded around 9pm.

Our opening night brought us 11 players. We had 8 players two weeks ago. And 8 this Monday night.

Our old location is still closed due to COVID concerns, so here we are at the Buffalo Wild Wings. Officially, we are not meeting there. Unofficially, a bunch of chess players are showing up, eating some wings and playing chess at the same time. 

We will try it again on Monday March 29th at 4pm until whenever! Stop on by.

Here part of an article by GM Andrew Soltis, paraphrased by your humble scribe. He is talking about draws - the alleged scourge of chess.

"We want our chess stars to play until it is King vs King, but we often seeing them shaking hands when there are still 30 pieces left on the board. You cannot force someone to play, but you can discourage draws. There have been many attempts at this by tournament organizers.

At Groningen in 1998, each GM was assigned an amount of money equivalent to his rating. For each win, the GM got 10% of your opponent's rating you collected in money and you lost the same 10% of your rating was lost. Good idea? No horrible. Since there was in fact no real prizes per se, there were only 6 win out of 30 games (20% verses the usual 33% to 45%).

Another try was to demand a replay. In a tournament in Paris 1900, the idea was that after a draw, there had to be a replay. The drawn game would not count. Good idea? No. It effectively gave the better player two chances to beat the lesser player.

They tried it again, but with a quarter point being issued to both players, with a replay for the remaining 1/2 point. Though better, it still left the stronger player with an edge and the choice to play for the 1/2 point or basically gentleman draw for the 1/4 point. Now your tournament draw of opponents became a little too relevant in the outcome of a tournament.

The most extreme anti-draw format was used in Paris in 1867. Draws were not replayed, they were ignored! It was like the game never took place! The problem with this became apparent near the end of the tournament, where the best players had to play reckless just to try and earn a win in a drawn position.  Otherwise they might lose too much ground to whoever was leading the tournament. The result was the lower rated players seemed to earn as many points as the better players later in the tournament, as the stars had to 'roll the dice'. [Ed. Note: It could also lead the way to some 'cash for a blunder' type situation. Not good]

What all this suggests is that we cannot abolish draws. But what about abolishing draws by 'agreement'.  The tradition of 'agreement draws' seems to have developed as a way for GM's to save energy in tournaments at different times during the tournament for various reasons.

This was tried in 2005 in the M-Tel super-tournament in Sophia. Draws could not be offered - only claimed due to rules." 

The other 5 rules for a draw in chess - besides agreement - include:

1. 50 - move rule - where no piece has be captured and no pawn has moved for 50 moves,  3 - move repetition,

2. Insufficient material for mate - neither side has enough material to checkmate the opponent.

3. Perpetual check - the king cannot get out of check, but cannot be checkmated either. Sometimes a person will use perpetual check to save a losing position because if he does not keep checking his opponents king, he will lose.

4. Stalemate - this is where the person who's move it is has no legal move but is not in check.

5. Same position or Three move rule - Here is when the same position has occurred in the game 3 times. This usually happens when opponents simply repeat the same moves 3 consecutive times. 

Well, guess which one of these rules did the GM's chose instead of an agreement or making a draw offer? 

Yes, you guessed it. Some pre-arranged signal was given and the GM's simply repeated moves 3 times!

So draws are here to stay. And along with the slowness of play and the difficulty for most to follow a chess game, chess will never be a TV ratings smash.

But this writer does not care. Who needs TV? We already know chess is the best game in the world.

A Chess Player's Life: Ivanov Part II - Beats the World Champion!

 Read about a true 'grinder' in the chess world in the last post - Igor Ivanov. Here is presented one of his best games. Enjoy.

Here is an example of Igor Ivanov’s moments of fame.

[Bracketed notes are from Igor3000]

Regular notes are from Igor Ivanov!

Spartakiad Tournament, Moscow, Russia 1979, Round 1

White: Igor Ivanov

Black: Anatoly Karpov

Sicilian Defense

Annotations by Igor Ivanov

1.       e4            c5

2.       Nf3          e6

3.       d4           cxd4

4.       Nxd4       a6

5.       Nc3          b5

6.       Bd3          Bb7

7.       O-O          Ne7

8.       Kh1          Nbc6

9.       Nxc6        Nxc6

10.   Qg4          h5

11.   Qe2          Ne5

Otherwise after 12. f4 Black will have no compensation for his weakened kingside.

12.   f4             Ng4

13.   Rf3           Qh4

14.   H3            Bc5

15.   Bd2           g6

I was not filled with optimism. I would have been content if Karpov would have given perpetual check (draw). The world champion’s decision is easily understood, but with his next move White completes his development, while the Black King is not safely placed. [last ‘book’ move is #17 for White]

16.   Raf1         Qe7

17.   A3            f5              my last move is preparing for counterplay on the queenside.

18.   Re1          Qf8

This loosens up coordination between Black’s pieces and therefore I decide to play actively. After 18. O-O White would be wise to limit himself to the more modest 19. Ref1.

19.   B4            Bd4

20.   A4            Rc8

21.   Nd1          Qf6

The f2-square is not safely defended, but the White knight does not stand too well. Unclear was 21. …bxc4. [21. ……bxa4 should have been considered 22. c3, Bf6 =]

22.   C3            Ba7

23.   Axb5        axb5

24.   Exf5         gxf5

The bishop on b7 is very strong and in order to initiate successful maneuvers on the queenside, I decided to sacrifice my rook for it. The decision to sacrifice was made much more easily because White doesn’t really have much else to do.

25.   Bxb5          Bxf3

26.   Qxf3          Rc7

27.   C4              Bd4

28.   Qd5           Kd8            [The backward pawn on d7 becomes a target]

29.   Qd6           Nf2+


Also after 29. ….Rg8 30. C5,Qg7 31. Bf1, Nh6 32. Ne3, Nf7 33. Qb6, White has enough compensation for the pawn.

       30.   Nxf2          Bxf2

       31.   Be3           Bxe3                        If 31.  …Bxe1 32. Bb6 with mating threats.

      32.   Rxe3         Qe7           

      33.   Qd2           Ke8?

      34.   Qd4           Rg8??

Black’s troubles grow. I feel that I this position White, without great risk, can attempt to create bigger threats. First a threat, then a double-threat that cannot be neutralized. For the first time in the game, I felt I might win!

35.   Qb6          Qg7            

36.   Qxe6+?    Kd8

I made a mistake! Everyone knows you must keep your composure until the very end, but not many of us actually do. After 36. Rxe6, Kf7 37. Re2  the rook on c7 is out of play and White wins easily.            

37.   Qd5          Ra7

I realized what I had done and felt just awful. But I calmed myself with the thought that my 36th move was payment for his 33rd move.

38.   Rd3           Ra1+??      

If I had played 38. Re1, then 38. ….Ra1 39. Rxa1, Qxa1+ 40. Kh2, Qg7 draws.

After this I have my win! Correct was 38. …..h4 and White can choose between two paths to a draw.

39.   Kh2           Ra2

42.   Qb6           Kc8

43.   Qa6+         Black Resigns
