G/55+5 (delay) E22 Nimzo-Indian Defense Spielman Variation

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qb3 Nc6
Copyright: Berthold Englisch, Vienna 1882!! [For 4...c5 see our 2009 KST opener.]

5.Nf3
White had to defend d4. [If 5.d5?! then 5...exd5 6.cxd5 Nd4! /\7.Qxb4?? (>=7.Qd1 Dittmann - Bachtiar : Leipzig 1960 7...Nb5=/+ TN 8.Qb3 Nxc3 9.bxc3 Ba5=/+ ) 7...Nc2+ 8.Kd1 Nxb4-+ ]

5...a5
[5...0-0 is the norm but I wanted to take my opponent out of book. For the unenlightened: By over-protecting the B, I ensure that a possible d4-d5 won't require trading on c3 with a tempo loss and also claim space that will prevent a later Q-side expansion by White.]

6.Bg5
[>=6.a3 a4 7.Qc2 Bxc3+ as in Fine - Reshevsky : U.S. Championship 1938 (the ...a5 stem game). 8.bxc3 d6 9.e4 e5 ; 6.e3 ; or 6.Bd2 ]

6...h6

[6...a4 7.Qc2 a3 8.Bd2 d6 9.e3 e5 10.bxa3 Bxa3 11.Be2 exd4 12.Nxd4 0-0 Zschinzsch - Sloth : ICCF 1967, is good, too. Btw, Sloth won the 8th World Correspondence Championship.]

7.Bh4?N
[Gavin - Muelas : Barcelona 2000 continued 7.Bxf6 Qxf6 8.e3 0-0 9.a3 a4 10.Qc2 Bxc3+ 11.Qxc3 d6 12.Bd3 Re8 13.0-0 e5 14.dxe5 dxe5 15.Be4 Na5= ]

7...g5 8.Bg3 g4?
This fails to take advantage of White's error. [8...a4! 9.Qc2 a3!-/+ was thematic and correct.]

9.d5 gxf3
[>=9...a4 10.Qc2 exd5 11.a3 Ba5 12.cxd5 Nxd5 although 13.Bh4 Nde7 14.Nd2 gives compensation for the P.]

10.dxc6 fxe2 11.cxd7+ Bxd7 12.Bxe2 Bc6?!
[>=12...Ne4 would have kept the balance.]

13.f3?
[13.0-0+/= /\ Nb5 was best.]

13...Rg8
[>=13...Nh5=/+ ]

14.Rd1 Qe7
Diagram



15.0-0?
[>=15.a3 Bc5 Sherer (or, more simply, as I suggested, 15...Bd6= ) 16.Bh4!<=> and now Black's safest is 16...a4 (16...Rxg2 opens up a can of worms: 17.Ne4 Nxe4! (17...Rg6 18.Nxf6+ Rxf6 & White will pick-up an Exchange but he can't as yet as 19.Bxf6? (19.Qc2 ) 19...Qxf6 is -/+.) 18.Bxe7[] Bxe7 19.fxe4 (19.h4 a4 20.Qa2 Ng3 21.Bf1 Nxf1 22.Kxf1 Bxf3 23.Rh3 Bxd1 24.Kxg2 0-0-0=/+ ) 19...Bh4+ 20.Kd2 Bg5+ 21.Ke1 (21.Kc3 Rxe2=/+ ) 21...Bh4+ 22.Kd2 Bg5+ 23.Ke1 Bh4+ 1/2-1/2) 17.Qc2 Bb6= /\ ...Qc5 (17...Rxg2 18.Ne4 Bxe4 19.fxe4 e5 20.Rf1~~ ) /\18.Ne4?! (18.Bf1 is best.) 18...Bxe4 19.fxe4 Qc5! 20.Bxf6? Qf2+ 21.Kd2 Be3+ 22.Kd3 Qxf6-/+ 23.Kxe3? Rxg2-+ ]

15...Qc5+?
[>=15...Bc5+ 16.Bf2[] (16.Kh1?? Rxg3!-+ /\17.hxg3 Nh5 18.Kh2 Nxg3!! 19.Kxg3 Qg5+ 20.Kh3 Qh5+ 21.Kg3 Ke7 & Black mates in 8.) 16...Nh5-/+ /\ ...Nf4]

16.Bf2 Qg5 17.g3 h5 18.a3 Bd6 19.Nb5
Diagram



19...Bf4!
Making use of the pin against g3, I preserve my d.s. B and stop White's intended Be3. [19...Bxb5 20.Qxb5+ Qxb5 21.cxb5 0-0-0 was an option but why go into an ending when all of my pieces (except for the Ra8) are placed for attack?]

20.Nd4 h4! 21.g4[]
[21.Nxc6?? loses to 21...hxg3! 22.hxg3 Bxg3 ]

21...a4!
Now we chase the enemy Q off the b-file to save the other cleric.

22.Qb4?!
This lets the Bc6 stay put and ends-up costing White a P. [>=22.Qc3 Bd7 23.h3= solidifying his weak spot.]

22...Bd6 23.c5!
[] [23.Qd2 , looking to trade Qs, falls to 23...Qe5-+ ]

23...Bxc5 24.Qc3
[>=24.Qd2 Qd5 25.h3 ]

24...Bxd4 25.Qxd4
Max offered a draw but, being ahead, I had no interest. [Furthermore >=25.Rxd4 ]

25...Nd5 26.Qd2??
[26.Rfe1=/+ was expected.]

26...Nf4! 27.Be3?
Diagram

[27.Rfe1 , clearing f1 for the K, was still the best try. Now White has big problems on the g-file and c6-h1 diagonal.] For the past 10 moves Black has masterfully conducted the attack...

27...Nh3+??
... But here he reverses the decisive move-order... [... and misses the murderous 27...Qxg4+!! /\28.fxg4 Nh3# ]

28.Kh1 Qxg4! 29.Bb5?
[Not 29.Rg1?? Nf2+! 30.Bxf2 Bxf3+ 31.Bxf3 Qxf3+ 32.Rg2 Qxg2# ; However >=29.Qd7+ Bxd7 30.fxg4-/+ ]

29...Bxb5 30.fxg4 Bc6+ 31.Qg2 Rxg4 32.Qxc6+ bxc6
Now I'm 3Ps ahead but there's no clear road to victory and time-trouble.

33.Rd3
Diagram

[>=33.Rf3 Ng5 34.Bxg5 Rxg5 35.Rh3 ]

33...Ng5?!
[>=33...Ra5! Sherer]

34.Rfd1?
[>=34.Bxg5 Rxg5 35.Rh3 ]

34...Kf8?
[>=34...Ne4 ]

35.Bd4
[>=35.Rd4 ]

35...Kg8?!
Down to 1:18 [>=35...Ne4 ]

36.Bc3 Kh7?!
[>=36...Ne4 37.h3 Nf2+ 38.Kh2 Nxd1 39.hxg4 Nxc3 40.bxc3 c5 ]

37.Rd7 Rc8 38.Bf6 Kg6
[>=38...Ne4 ]

39.Rf1
[>=39.Bxg5 Rxg5 40.R7d4 ]

39...Ne4 40.Be5
Diagram



40...f5??
[40...f6-+ /\41.Bxc7? h3 was right.]

41.Rf3??
[41.Rg7+ Kh5 42.Rh7+ Kg6 43.Rg7+ Kh6 (or 43...Kh5 44.Rh7+ Kg6 45.Rg7+ 1/2-1/2, especially since I had just 20 seconds left.) 44.Rxg4 fxg4 45.Rf4 Nc5 46.Rxg4 Kh5 47.h3=/+ ]

41...Nd2??
This loses the N and the game. [41...Ng5 was still winning for me.]

42.Rxd2 Rg8
Resigns was indicated.

43.Rg2?!
[>=43.Rf1+- ]

43...Kh5
[>=43...Kf7 44.Rxg4 Rxg4 45.Bxc7 Rd4+/- ]

44.Rff2?!
[>=44.Rxg4 Rxg4 45.Re3+- ]

44...Rxg2 45.Rxg2 Rxg2?
[>=45...Rd8 46.h3 Rd5 /\47.Bxc7? e5+/- ]

46.Kxg2 Kg4 47.h3+ Kg5 48.Kf3
& Black played on until he was mated somewhere around move 64. Estimated time left - Sherer 0:50, Moldovan 0:12 Estimated time used - Sherer 58:00, Moldovan 60:00 Longest think by White - 5 minutes for 9.d5 and 18.a3 Longest think by Black - 14 minutes for 19...Bf4! I was stupid for being greedy and not grabbing the half-point at some juncture. 1-0
