Garden State Chess League 2009-10 Kenilworth, NJ (1), 08.10.2009
[Moldovan, Deep Rybka 3 & HIARCS 11]
G/75 + :05 delay
A44 Old Benoni Defense
, postponing central commitment, is more flexible but the text keeps certain East Indian weapons in hand.]
, which my foe used to beat GM Maxim Dlugy in 1990! See http://www.kenilworthchessclub.org/articles/history/club/part4.htm]
[Heading for a Caro-Kann Exchange with 2.e3
; , or a Slav Exchange with 2.c3
, was an option but, with my team out-rated on the top boards, trying to exploit Black's move order was indicated.]
The most natural reaction. [4.Bd3
, recommended by Horowitz (Chess Openings : Theory & Practice) & Kmoch (Pawn Power In Chess), just doesn't impress.; & 4.c4
is supposedly weaker; despite the advantages obtained in Kernighan - Lewis : KST 2007 & Shiffman - Wojcio : Kenilworth Ch. 2008.]
[I expected 4...Be7
+ 6...Bxf3 & the thematic trade of dark-squared clerics via ...Bg5.; 4...a6
, preventing my next move & preparing ...b5, is another common reply.
All I could find on 4...Nf6, which parodoxically may now be a bit premature, was a few notes in MCO & NCO.]
[According to ChessBase 5.Nf3
is most common.]
[Another surprise. 5...Bd7
This boldly "Grobs" space and looks to displace the Nf6 which doesn't have d7 (thanks to the B check), h5 (thanks to the Nf3 omission) & e8 available. [However, since White's aim is to restrain, not kill, 6.a4
preventing Black from expanding on the other wing 6...a6
/\ g4!? was precise.]
; or 7...b5
is equal.) 10...b5
threatening to take the e4P 9.Bd2
keeping the Nf6 from being pushed back.]
Playing to open the h-file is best. [‹10...h5
This shields the Rh1 so I can recapture at g5 with the hP.
, though playable, is inconsistent (doesn't restrain) and isolates the hP.]
This lets Black develop the gN but makes his d.s. B bad. [>= ...Be7, putting pressure against g5. For examples :
exploiting the pin on the Nh3 & winning a P 15.Bxc8
(=/+ Rybka; -/+ HIARCS)) 15...Qxc8
; B) 12...Be7
loses to 19.Qc8+
with less of a disadvantage than in the game.]
; But 13.Qd3
/\ f3, Ke2, Be3 + Nf2 was a reasonable alternative.]
is also good for White.]
/\ Qf1 14...Nf8
[Black misses a chance to gain some territory via >=14...c4!+/=
Despite eliminating my g5P and trading Qs, Black stands worse, due to his bad B & weak gP. To make matters worse, he is behind on the clock... 54 minutes to 29.
This overlooks a fork & loses an Exchange. [Something like 20...Nh5
/\ ...Ng7 & additional trades should've been played.]
[Keeping the B active with 21...Bxe3
was little or no better.]
With the R swap the Q-side becomes vulnerable.]
Playing to maintain an all-over bind is unnecessarily slow. [24.a5!
+ Rxa6) 25.Nxb5!
would have broken through right away.]
This freezes the Ne7.
Black swings his K around to f7, to protect g7+g6 & free the aforementioned equine, but ...Nh7, here or next, seems a bit better. [26...Nh5
threatening to win the g6P (or 27.Ng3
threat : Nxh5 28...Bxg5
, on the other hand, is no improvement.]
This stops ...Nh5.
This sets a fiendish trap.
/\ ...Bh6 [If 28...Nh7?
(A quadruple discovered attack) & White wins the d6 P because 30...gxf5?
loses to 31.Rxg7+
This prevents ...Bh6, ...Nh7 & ...Nh5.
followed by ...Be7 but, apparently stumped for a plan, Black opts to temporize & await developments.]
This overprotects e4 + g4 & prepares Ke2 followed by Nf1-d2-f3 but Ne2, here or next, was best.
+ 35.Bxa5) 34.Rh7+
, just-about putting Black in zugzwang, was more accurate.]
Diagram Threatening to get rid of the bad B with ...Bf6.
Loathe to allow the aforementioned or retreat further, I return the Exchange to raid the Q-side with my B and obtain a passer.
The hP won't be a problem. In the long run it is doomed.
[The engines say 35.Kf3
was required. Now Black drops a 2nd P.]
This attempts to trap my B but loses yet another chip.
was just as hopeless.; 40...h3?
is even more so.]
Time left - Moldovan 31:00, Lewis 7:00
Estimated time used - Moldovan 47:30, Lewis 71:30
Longest think by White - 6 minutes for 13.Be3
Longest think by Black - 11 minutes for 12...Bg7
This win clinched the match for the Karpovs, who dispatched the champion Kortchnois 2.5-1.5. 1-0
