[Moldovan, Deep Rybka 3 & HIARCS 11]

board 3 G/75 + :05 delay A44 Old Benoni Defense

1.d4
[Overall, 1.Nf3 , postponing central commitment, is more flexible but the text keeps certain East Indian weapons in hand.]

1...c5
[>=1...Nf6 2.c4 c5 , which my foe used to beat GM Maxim Dlugy in 1990! See http://www.kenilworthchessclub.org/articles/history/club/part4.htm]

2.d5
[Heading for a Caro-Kann Exchange with 2.e3 /\cxd4 3.exd4 d5 ; , or a Slav Exchange with 2.c3 /\cxd4 3.cxd4 d5 , was an option but, with my team out-rated on the top boards, trying to exploit Black's move order was indicated.]

2...e5 3.e4 d6 4.Nc3
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.]

4...Nf6
[I expected 4...Be7 /\5.Nf3 Bg4 + 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.]

5.Bb5+
[According to ChessBase 5.Nf3 Be7 6.Be2 0-0 7.0-0 Ne8 8.Nd2 is most common.]

5...Nbd7
Diagram

[Another surprise. 5...Bd7 6.a4 Be7 was anticipated.]

6.g4!?N
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 7.Be2+/= /\ g4!? was precise.]

6...a6 7.Be2 g6
[>=7...h6 8.a4 Qa5 9.Bd2 Be7 ; or 7...b5 8.g5 Ng8 (8...b4!? 9.gxf6 bxc3 10.fxg7 Bxg7 11.bxc3 Qa5 12.Qd3 Nf6 ) 9.h4 h6 ]

8.a4
[8.g5 Ng8 9.h4 h6 (9...b5 allows 10.h5|^ ) 10.Nh3 (10.a4 hxg5 11.Bxg5 f6 is equal.) 10...b5 ]

8...b6
[>=8...Qa5 threatening to take the e4P 9.Bd2 h6 keeping the Nf6 from being pushed back.]

9.g5 Ng8 10.h4 h6
Playing to open the h-file is best. [10...h5 11.f4! ]

11.Nh3!
This shields the Rh1 so I can recapture at g5 with the hP.

11...hxg5 12.hxg5
Diagram

[12.Nxg5 , though playable, is inconsistent (doesn't restrain) and isolates the hP.]

12...Bg7
This lets Black develop the gN but makes his d.s. B bad. [>= ...Be7, putting pressure against g5. For examples : A) 12...Be7 13.Be3? Nf8 14.Bg4 Bxg5! exploiting the pin on the Nh3 & winning a P 15.Bxc8 (15.Bxg5? Qxg5! 16.Bxc8 Rxc8 17.Nxg5 Rxh1+ 18.Ke2 Rxd1 (=/+ Rybka; -/+ HIARCS)) 15...Qxc8 16.Bxg5 Rxh3 17.Kd2 ; B) 12...Be7 13.Qd3! Nf8 14.Qf3! (14.Qg3 Qd7! 15.Bf1 Qg4= ; 14.Bf1 Rh5= ) 14...Rxh3! 15.Rxh3 Bxh3 16.Qxh3 Bxg5 17.Bxa6! Bxc1 (17...Rxa6? 18.Bxg5! f6 (18...Qxg5? loses to 19.Qc8+ Ke7 20.Qxa6 ) 19.Qd3 Ra7 20.Be3+/- ) 18.Bb5+ Nd7 19.Rxc1 Ngf6 with less of a disadvantage than in the game.]

13.Be3
[13.Bg4 c4! 14.Be3 Nc5= ; But 13.Qd3 Nf8 14.Qg3 Qd7 15.Bf1 Qg4 16.Qxg4 Bxg4 17.Bg2 /\ f3, Ke2, Be3 + Nf2 was a reasonable alternative.]

13...Ne7
[13...f5 14.gxf6! Ndxf6 15.Bf1 is also good for White.]

14.Bg4
[14.Kd2! /\ Qf1 14...Nf8 15.Bg4 was best.]

14...f5?
[Black misses a chance to gain some territory via >=14...c4!+/= /\ ...Nc5]

15.gxf6 Nxf6 16.Bxc8?!
[>=16.Be6! Bxe6 17.dxe6 d5 18.exd5 Nexd5 19.Qf3+/- ]

16...Qxc8 17.Qf3 Qg4 18.Ke2 Qxf3+
[>=18...Rh5 19.Qxg4 Nxg4 ]

19.Kxf3 Kd7
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.

20.Ng5
Diagram



20...Bh6??
This overlooks a fork & loses an Exchange. [Something like 20...Nh5 21.Ne6 Bf6+/= /\ ...Ng7 & additional trades should've been played.]

21.Nf7+- Bg7
[Keeping the B active with 21...Bxe3 22.Rxh8 Rxh8 23.Nxh8 Bd2 24.a5 was little or no better.]

22.Nxh8 Rxh8?
[>=22...Bxh8 With the R swap the Q-side becomes vulnerable.]

23.Rxh8 Bxh8 24.Ne2?
Playing to maintain an all-over bind is unnecessarily slow. [24.a5! b5 (24...Kc7 25.axb6+ Kxb6 26.b4! ; 24...bxa5? 25.Rxa5 + Rxa6) 25.Nxb5! axb5 26.a6 would have broken through right away.]

24...Bg7 25.c4
Threatening a4-a5.

25...a5
Diagram



26.Rg1
This freezes the Ne7.

26...Ke8
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 27.Bg5 threatening to win the g6P (or 27.Ng3 Nf6 (27...Nxg3 28.Rxg3 ) 28.Bg5 ) 27...Nf6 (27...Bf6 28.Ng3! threat : Nxh5 28...Bxg5 29.Nxh5 Bd2 30.Nf6+ ) 28.Nc3 , on the other hand, is no improvement.]

27.Ng3
This stops ...Nh5.

27...Kf7 28.Bg5!
This sets a fiendish trap.

28...Neg8
/\ ...Bh6 [If 28...Nh7? then 29.Bxe7 Kxe7 30.Nf5+! (A quadruple discovered attack) & White wins the d6 P because 30...gxf5? loses to 31.Rxg7+ ]

29.Rh1
This prevents ...Bh6, ...Nh7 & ...Nh5.

29...Kf8
[>=29...Bf8 followed by ...Be7 but, apparently stumped for a plan, Black opts to temporize & await developments.]

30.Rh4
This overprotects e4 + g4 & prepares Ke2 followed by Nf1-d2-f3 but Ne2, here or next, was best.

30...Kf7 31.Ke2
[31.Nf1 /\Nh5 32.Bd8! Bf6 33.Rxh5! Bxd8? (>=33...gxh5 34.Bxb6 + 35.Bxa5) 34.Rh7+ Ke8 35.Ne3 , just-about putting Black in zugzwang, was more accurate.]

31...Kf8 32.Nf1
[>=32.f4 exf4 33.Bxf4 Ne8 34.Rh1 Bxb2 35.Rb1 Bc3 36.Rxb6 ]

32...Nh5
Diagram

Threatening to get rid of the bad B with ...Bf6.

33.Rxh5!
Loathe to allow the aforementioned or retreat further, I return the Exchange to raid the Q-side with my B and obtain a passer.

33...gxh5
The hP won't be a problem. In the long run it is doomed.

34.Bd8 Nf6 35.Bxb6
[The engines say 35.Kf3 /\Nd7? 36.Ng3 was stronger.]

35...Nd7?
[35...Nxe4 36.Bxa5 Ke8 37.f3 Nf6 was required. Now Black drops a 2nd P.]

36.Bxa5 Nb8?
This attempts to trap my B but loses yet another chip.

37.Bc7 Na6 38.Bxd6+ Ke8 39.Ng3 h4 40.Nh5 Kd7
[40...Bh8 41.f4! exf4 42.e5 was just as hopeless.; 40...h3? 41.Nxg7+ Kf7 42.Bxe5 h2 43.Bxh2 is even more so.]

41.Nxg7 Kxd6 42.Nf5+
Black resigns 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
