We start back next Monday! We have a lot of fun events planned for 2015, so tell all your chess playing friends to get to LCCC!
Now a game from our league. Special thanks to Gene McClure for running it thru Rybka and adding his notes. I ran it thru my Igor3000 also (see I3 notes).
Gene McClure vs. Vince Valente
Analysis by[Rybka 4 x64 (15s)]
B00: Queen's FianchettoDefence, NimzowitschDefence
R: Last book move I3: White is up (.6)!
R: White has an active position
Gene: Vince said after the game he was glad I offered to trade my dark-squared Bishop, and I agree it could have helped defend f4 from his incoming Knight. Rybka gives 10. a3 Bxc3, 11.Bxc3 0-0, 12.Re1 Bd7 (+0.3).
R: Black has a cramped position I3: Not that cramped (.1). If Black had castled last move, the game is EVEN.
12.c4?! (= Rybka)
Gene: Rybka gives Ng3 or Qc3. I agree it would have been preferable to put the question to the h5 Knight with Ng3 at this point, avoiding some upcoming questionable defensive moves.
I3: White is going backwards (-.7)
15.Rg1?! R:[15.Ng1 Qh6=] I3: (-1)
16.Rh1?![16.Ne1 g4³ is a -2 advantage for Black]
R: Deflection: f3 I3: Prettier, but not as good as 16. ,,,,g4, so only (-1.4)
Gene: (-1.0 Rybka) White placed the wrong defender on g1 on move 15, not anticipating 16...Nxh3!
[17.gxh3 Qxf3 Overloading Deflection Discovered attack]
17...Nf4?! [17...Bg4 18.gxh3 Bxf3 19.Rg1µ]
18.Kg1 [18.g3 Bg4 19.Ne1 Ng6³]
18...Bg4 [18...g4 19.Ne1µ] I3: (-1.1)
19.Nh2 White threatens to win material: Nh2xg4
21.g3 Nh3+?![21...h4 22.Nf3 hxg3 23.Rxh8+ Qxh8 24.fxg3µ I3: (-1.7)]
[24.Kg2!? Bxf3+ 25.Qxf3 Qxf3+ 26.Kxf3µ]
25. Nh3? [25.f3 Rxg5 26.fxg4 Rxg4 27.Rxh5–+] I3: (-3.3)
26.Rh2?! not the greatest defence [26.Kh2 Bxh1 27.Rxh1 h4–+] I3: Now (-3.8)
27.Kf1 [27.Rg2 cannot undo what has already been done 27...Rg4–+]
28.fxg3 Rxg3 I3: (-4)
29.Ke1? [29.Qf2 desperation 29...Qg7 30.Re1–+] I3: Ouch, now (-7)
29...Qh4 (-5.7 Rybka)
[¹30...0–0–0 and the rest is a matter of technique 31.Kd2 Bxe4–+ I3: (-8)]
I3: A blunder! Castling was the move to shut down all counter play. Now after Kd2, Whites a1 rook now can come in to help out. (-2.7)
31.Kd2 Rg2?/ (+0.6 Rybka) I3: Advantage gone! (.4)
There were better ways to keep up the pressure [¹31...Qg6 would have given Black a clear advantage 32.Rg1 Rxg1 33.Qxg1 Bh5–+]
|After 32. .......Bxg2|
33.Re1? gives the opponent new chances [¹33.Ng5 Qg6 34.Qxg2²] I3: (-2.6)
Gene:After 33.Re1?:(-2.0 Rybka).Two other moves: (1) 33.Ng5! removes the Black Bishop threat to the White Knight while also forking the Black Queen and f7 Pawn. Black can then play either ..Qg6 defending f7 (+0.6), or ..Qf4+ exchanging
(+0.8).(2) A club observer suggested 33.Rg1? after the game as it appeared
White would win the exchange, but Black quickly obtains a Knight and two Pawns
for his Rook, and the White King is left open to repeated Queen checks: 33...Bxh3, 34. Rg8+ Ke7, 35.Rxa8 Qxc4, 36.Rg8
Qxd5+ (-2.5 Rybka). I3: after 33. Ng5, see the mate threat.
33...Qf3? forfeits the advantage [33...Qg4 34.Rg1 Qxh3 35.Rxg2–+] I3: (-.5)
34.Qxf3? [¹34.Re3 and White can hope to live 34...Qxf2+ 35.Nxf2³] I3: (-2.3)
36.Rh1 [36.Rg1 f5–+]
37.Rg1 [37.Rh7 Rf8 38.Ke3–+]
37...Bf5 I3: (-3.7)
