A08 King's Indian Attack

HCA Winter Open Tampa (2), March 26, 2011 [Notes by Hoffer]

This is another masterpiece from ten-year-old Truman Hoang. He thoroughly dominates an opponent rated 600 points higher and three times his age!

1.e4 c5 2.Nf3 g6

The Accelerated Dragon doesn't have the best reputation, yet we must assume Black is comfortable with it.

3.g3!?

There are more possible chess games than atoms in the foreseeable universe. The Sicilian compromises a high percentage of them with complex variations you sometimes need to know 30 moves deep to survive the latest improvement played last week in Wijk aan Zee. A safe alternative to avert the main lines of the Sicilian is the King's Indian Attack which is most usually entered by playing 3.d3. Fischer's fingerprints abound throughout this variation.

3…Bg7 4.Bg2 Nc6 5.0–0 e6 6.d3 Nge7 7.Nbd2

A reasonable move. White has three other interesting choices:

A) 7.d4!?N Back in 2005 I tried this experimental a pawn sacrifice here to gain rapid development and open lines for attack against a couple of WIMs with spectacular results: 7…cxd4 8.c3! dxc3 9.Nxc3 0–0 (9…d5 10.exd5!) 10.Qd6 Qb6 (10…a6 11.Bg5 f6 12.Bf4 Qb6 13.Rab1 Qb4 14.Qd1 b5 15.Bd6 Qa5 16.b4 Qd8 17.a4 Bb7 18.axb5 axb5 19.Qe2 Qb6 20.Bc5 Qd8 21.Rfd1 Ba6 22.Rd2 d5?

b) 7…b6 Black deferred playing …d5, which was a little unsettling as I was wondering what he was up to. My opponent, International Master Ron Burnett of Tennessee, is one of the strongest players in the South. Ron was the inaugural winner of the US State Champion of Champions. He was 38-years-old at the time of this game. I recall how back around 1991, young Ron would put on his Reeboks and jump on a Greyhound bus taking his 2500 rating around the country. He arrived late to a tournament in Miami, took a half-point bye and still won the tournament ahead of such luminaries as GM Eduard Gufeld, IM Boris Kogan, and SM Gary Sanders! 8.Na3 0–0 9.Qb3!?N (9.Re1; or 9.e5 ) 9…d5 10.Bg5 h6 11.Be3 Bb7 12.Rad1 Kh7 13.Rfe1 Rc8 14.c4!?
