G/60+30 E73 King's Indian Defense Insanity Variation Deferred

1.c4 I really wasn't in the mood to face another K's Indian but after...

1...Nf6 2.Nc3 g6 3.e4 d6 I had a change of heart & decided to confront the issue.

4.d4 [RR4.d3 Bg7 5.g3 0-0 6.Bg2 Nc6 7.Nge2 Bg4 8.f3 Be6N 9.Be3 Ne5 10.Nf4 Bd7 11.h4 h5 12.Qe2 c5 13.0-0 a6 14.Rfd1 Nc6 15.Qf2 Qa5= Moldovan - Fischler : STC Gauntlet, U.S. Chess Live 07/23/2005]

4...Bg7 5.Be2 0-0 6.Be3 [For 6.g4 see Stoyko - Thomson : GSCL match , Summit 06/29/2009.; 6.Bg5 the Averbakh Variation was another option.]

6...Na6 Diagram

[For 6...Nc6 see my opponent's 5th round draw vs. gotleib.]

7.g4!? [7.Nf3 is objectively best but I needed to win & felt something sharper was in order.]

7...h6N This slows g4-g5 but weakens g6 & gives me an extra target (h6) to work against. [>=7...c5 ; 7...e5 ; & 7...Qe8 have been played as well.]

8.f3 [>=8.h4+/= /\c5 9.g5 hxg5 10.hxg5 Nh7 11.d5 ]

8...c5 9.d5 Qa5 10.Qd2 [>=10.Nh3 h5 11.Nf2 hxg4 12.fxg4 ]

10...Kh7 [>=10...h5 ]

11.h4 Diagram



11...e6? [11...h5= would have maintained the balance.]

12.g5 This wins a P... [... But Rybka says >=12.h5! g5 13.Nh3+/- /\ of sacking on g5. For example : 13... 13...exd5 14.cxd5 Nc7?? 15.Bxg5!+- hxg5? 16.h6! Bxh6 17.Nxg5+ Kg6 18.Rxh6+!! Kxh6 19.Ne6+ Kh7 20.0-0-0! fxe6 21.Qg5 Kh8 22.Rh1+ Nh7 23.Qe7 Rf7 24.Qxf7 with mate to follow]

12...Nh5 [‹12...hxg5 13.hxg5+ Nh5 14.f4+/- ; 12...Ng8? 13.h5+- ]

13.gxh6 Bh8?? [After this Black is lost. He should've played 13...Bxc3 14.bxc3 e5+/= ]

14.Nh3 Diagram



14...f6? [This stops Ng5+ but entombs his ds B & leaves his K with little wriggle-room. >=14...Bxc3 15.Ng5+ Kh8 16.bxc3 exd5 17.cxd5 Bd7 ]

15.dxe6 Bxe6 16.Qxd6 [>=16.f4 Ng3 17.f5 ]

16...Bf7? [>=16...Rfe8 17.0-0-0 Bxh3 18.Rxh3 Rad8 ]

17.0-0-0 Rad8 18.Qh2 Diagram

You don't see a lineup like this very often. Every square on the h-file is occupied.

18...Nb4 19.Kb1 Nc6 [>=19...Rfe8 ]

20.f4 [>=20.Nd5 ]

20...Nd4 21.Bd3 [>=21.Rhg1 ]

21...Qb4 Diagram

[>=21...Qc7 22.Nd5 Qd7 ; ‹21...Kxh6? 22.f5+ Kg7 23.fxg6 Bxg6 24.Nf4 ]

22.Qf2?! [>=22.Nd5 ; & 22.f5 were stronger.]

22...Bxc4 [22...Rg8 does not save the day : 23.f5 Bxc4 24.Nd5 Bxd3+ 25.Rxd3 ; ‹22...Kxh6? 23.f5+ Kh7 24.Rhg1 ]

23.Bxc4 [>=23.f5 Rg8 24.Nd5 Bxd3+ 25.Rxd3 ]

23...Qxc4 24.f5 Rg8 25.Rhg1 [>=25.Nd5 Rxd5 26.fxg6+ Rxg6 27.exd5 Qxd5 28.Bxd4 cxd4 29.Rhe1+- I didn't play the attack perfectly but many of these notes wouldn't have generated if more than a 1/10th P threshold was used.]

25...Qf7? The pressure is too much. Black crumbles. [25...gxf5 26.exf5 Rxg1 27.Qxg1 Rg8 was a much better try. Now I expose a pin against the fP, win an Exchange & reinforce my h6 passer.]

26.fxg6+ Rxg6[] Diagram



27.Ng5+! Rxg5[] Otherwise he loses his Q.

28.hxg5 Rg8 [‹28...Qg6 29.Qh2 /\ Qc7+ 29...Rd7 30.Qh3 ]

29.Bxd4 cxd4 30.Rxd4 [30.Qf5+ Qg6 (‹30...Rg6 31.Rxd4 threat : Rd7) 31.Qd7+ Bg7[] 32.Qxd4 was good, too; not to mention funny. Notice how of all Black's pieces are huddled in 1 corner.]

30...f5 [30...Qe6 31.g6+ Rxg6 32.Rxg6 Kxg6 33.Rd8 Kh7 34.Qxa7 was best but just as hopeless.]

31.Rd6 Diagram

&, faced with the prospect of losing his R to g6+, Black resigned. Time left - Moldovan 9:10, chessforlove 22:56 Time used - Moldovan 66:20, chessforlove 52:04 Longest think by White - 10:13 for 15.dxe6 Longest think by Black - 9:37 for 24...Rg8 Start - 8:06:16 p.m. End - 10:10 p.m. Game length - 2 hours, 4 minutes [including reconnection time after Ng5+ knocked him offline :-)] 1-0
