board 3 G/75 + :05 delay A42 Modern Defense Averbakh Variation

1.Nf3 g6 2.c4 Bg7 3.d4 d6 4.Nc3 Nd7
[I expected 4...Bg4 , as played by Resika in the recent USATE; 4...f5 & a Leningrad Dutch; or 4...e5 /\5.dxe5 dxe5 6.Qxd8+ Kxd8 ]

5.e4 c5 6.Be2
Diagram



6...e6?
This weakens d6. [6...cxd4 7.Nxd4 Ngf6 seems right.]

7.Be3?!
[7.Nb5 Qb6 8.dxc5 dxc5 9.0-0+/- was best.]

7...b6?N
This leaves my foe unable to laterally defend his sore spot. [Rybka suggests coughing-up a P with 7...Ne7 Goihl - Swemers : Siegburg 1997 (7...Qc7? has also been played) 8.Nb5 0-0 9.Nxd6 Qb6+/= ]

8.Qd2?
Following the "don't move the same piece twice in the opening" mantra to a fault. [8.Nb5 Bf8 (8...Ke7 9.Bf4 e5 10.dxe5 Nxe5 11.Qd5 Be6 12.Qb7+ Kf8 13.0-0-0 is no better.) 9.Bf4 a6 10.Nxd6+ Bxd6 11.Bxd6+- would have refuted Black's play.]

8...h6?
[This stops Bh6 but there was no real need to as 8...Ngf6 (making the Nc3 stay put) /\9.Bh6 Bxh6 10.Qxh6 Bb7 11.d5 e5 12.Qg7 Ke7!+/= (looking to force the Qs off with ...Qf8) would've been fine.]

9.h3?
Again, Nb5 was winning.

9...Bb7
Now an attack on d6 can be countered by one against e4. [For example: 9...Bb7 10.Nb5 Ndf6 11.dxc5 Nxe4 12.Nxd6+ Qxd6 13.Qxd6 Nxd6 14.cxd6 Bxb2 15.Rb1 Bc3+ 16.Kf1 Nf6+/= ]

10.0-0 Ngf6
Diagram



11.d5!
This turns the Bb7 into a tall P & solidifies e4. [11.Qc2 cxd4 12.Nxd4+/= ]

11...e5
[Sobin doesn't want to further weaken g6 (8...h6 has already done that) by allowing me to trade on e6 & he doesn't want to swap at d5 because after 11...exd5 12.exd5!+/- his K would be exposed on the open file.]

12.Ne1
[12.Bd1 /\ Ba4 was an option; as was the thematic 12.a3 + b4.]

12...Qe7 13.a3 Ng8
[13...h5 followed by ...0-0 is less artificial.]

14.Bd3
This prophylactic isn't bad... [But starting the offensive, at once, with 14.b4 , was a good alternative; since 14...f5 15.exf5 gxf5 16.Bh5+ Kd8 (or 16...Kf8 17.g3 ) 17.bxc5 bxc5 18.Nb5! /\ Qa5+ takes care of the ...f4 menace.]

14...Bf6
Diagram

[This makes room for the K &/or looks to exchange d.s. Bs. Rybka prefers 14...Ngf6+/= but you can understand a human not wanting to retract his previous move. The same can be said about Black's 16th & 19th.]

15.g3!
If 15...Bg5, I'll just drive the cleric back & gain space with 16.f4.

15...Bc8
[But I would've have left the l.s. cleric at b7, opted for 15...Kf8 16.b4 Kg7+/= & tried to connect Rs.]

16.Kh2 Bg5?!
This just increases White's advantage. [>=16...Bg7+/= ]

17.f4 Bf6
Forced. [17...exf4? 18.gxf4 Bf6 loses to 19.Nb5 ]

18.Nf3 Nf8?
[18...Kf8+/- , getting the K to safety, was more circumspect.]

19.Rf2?
[>=19.fxe5 dxe5 20.b4+- But I was more concerned with stopping Black's designs against h3.]

19...Qd7?
[19...Nd7+/- ]

20.Bf1+- g5
[>=20...Nh7 ]

21.fxe5! dxe5 22.Ng1?
[>=22.b4 ]

22...Ng6?
Diagram

[>=22...g4 ]

23.b4
Finally!... [But Rybka says >=23.Be2 + doubling Rs on the f-file.]

23...cxb4?
After this, it's all downhill. [23...Be7 was a much better try.]

24.axb4
With the dual threats of 25.Bxb6 & 25.c5 + 26.Bb5, the latter of which Black apparently missed.

24...Bd8?
[>=24...Qd8 ; or 24...Kf8 ]

25.c5 Qb7 26.c6 Qb8 27.d6
Diagram

/\ 27...Be6 28.Nb5 followed by c7. White is going to win a piece.

27...Bd7
Desperation. Resigns was a good alternative. [I shouldn't poke fun at the enemy's plight but can't resist: 27...Nf8 would've completed the picture ;-)]

28.cxd7+ Kf8 29.Bb5?!
[>=29.Bc4 Nf6 30.Raf1 ]

29...a6
[>=29...Kg7 30.Bc6 Nf6 /\31.Bxa8 Qxa8 32.Qc2 Nxd7 ]

30.Rxa6?!
[>=30.Qd5! Nf6 31.Rxf6! Bxf6 32.Bc4 Rh7 33.Rf1 ]

30...Nf6?
[>=30...Rxa6 31.Bxa6 Nf6 32.Bb5 Kg7 ]

31.Qa2 Rxa6 32.Qxa6 Kg7
[Not 32...Qxd6? 33.Bc5! ]

33.Rd2 g4 34.h4?!
>= Qc8, here or next

34...Nxh4
Short of time & looking to ignite his extinguished (never-existant?) flame, Black throws more wood on. [>=34...Nh5 ]

35.gxh4 g3+
[>=35...Nh5 ]

36.Kh3 Nh5 37.Nge2
[>=37.Qc8 Bf6 38.Qxb8 ]

37...Bxh4
One more, just for the heck of it. [>=37...Bf6 ]

38.Qxb6
[>=38.Kxh4 ]

38...Qa8+-
At this point, with Joe Demetrick having won on board 4 to give our team a 2-1 lead, I offerred a draw but, instead of accepting it, my opponent resigned. A very gentlemanly gesture. Final Score : Karpovs 3, Sparta 1 Time left - Moldovan 7:20, Sobin 0:36 Estimated time used - Moldovan 70:55, Sobin 77:39 Longest think by White - 10 minutes for 26.c6 Longest thinks by Black - 7 minutes for 12...Qe7 & 24...Bd8? 1-0
