Chess Club Busy 120318 - and Kid's Night This Coming Monday!

Always record your games for analysis later!

The chess action is on right now each Monday night! We had 17 players this Monday - including seven of the school aged variety - and it was not even Kids Night!
But we are fixing that this coming Monday as Kid's night is this week.
Hope to see you there - even if you are an 'older' kid.

Here is a game between two GM's - Ravinsky vs Panov, Moscow 1943.
It's the old story at that level. Do you take material, and lose time and some positional strength - or do you hold steady?
Panov - with the Black pieces - goes out of his way to steal a pawn. Ravinsky with White tries to find compensation for the lost soldier with gaining time, development and starting his attack faster.
Such situations are found often in the Sicilian Defense lines. My computer Igor3000 tells me this happens to be the Scheveninggen line of the Sicilian Defense. Ok, like I care!
For you e4 players and Sicilian Defense lovers, I'll start at the beginning.

1. e4            c5
2. Nf3          e6
3. d4            cxd4
4. Nxd4       Nf6
5. Nc3         d6
6. g3            Nc6
7. Bg2         Bd7
8. O-O         a6
9. Be3         Rc8
10. Qe2       b5
11. a3          Ne5
12. Rad1     Nc4

White to make move 13

Black is now threatening to win material. But is it the correct plan? Igor says no and Black will win the pawn and actually be a pawn down due to positional issues (+1.1). Ravinsky would not have calculated to that extreme, but did sense and see that he would have counter play for his pawn he lost. Such is the nature of top level chess. Panov was thinking "I'm a pawn up! Now to first fortify my position, then grind out my win."
Who will be right?

13. Bc1         Nxa3?
Hard to find but Igor suggests 13. ....h5 to gain space and give White something to worry about on the King side. A human probably never plays this move. (+1.1)

14. e5           dxe5


15. Nc6         Qc7
16. Nxe5       Nc4
17. Nxd7       Nxd7
18. Nd5         Qa7?
Correct was 18. .....Qe5, 19. Qf3, Qb8 - staying a pawn down. Now Black is down almost two pawns positionally (+1.8) according to Igor.

19. Nf4         Nce5
20. Rxd7      Nxd7?
Black is slipping into the abyss. This happens when defending. It is hard to find the right defensive line every move. 20. .....Qxd7 21. Qxe5, Rxc2 was better. (+2.2).

21. Nxe6         fxe6
22. Qxe6+       Be7
23. Re1           Qc5
24. b4              Nf8
Black correctly stayed away from 24. ......Qxb4?? as 25. Bf4, Qxe1+ 26. Qxe1 is bad for Black.

25. Qg4           Qc3??
The final mistake in a bad position. 25. .....Qc4 was best. Now White leads (+13).

26. Rxe7!         Kxe7
27. Bg5+          Kd6
28. Qd1+          Kc7
29. Bf4+           Kb6
30. Qd6+          Ka7
31. Qe7+          Rc7
32. Bxc7          Qa1+
33. Bf1             Ng6
34. Qc5+          Kb7
35. Ba5            Rf8
36. Qb6+          Resigns
