White: GM Sergey Kudrin
Black: Peter Bereolos
Midwest Masters Invitational, 1987
Round 3 Board 8
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.b4 Bb6 6.d3 a6
With the move order employed by White with an early b4, Black should play 6...d6 and wait for White to spend a tempo on a4 before committing to ...a6
7.0-0 d6 8.Nbd2 0-0 9.Bb3 Be6
9...Ne7 is probably a bit better.
10.Nc4 Ba7 11.Bg5 h6
If Black is going to allow his f pawns to be doubled as in the game then he should avoid this weakening of the kingside.
The only consistent follow-up is 12...g5. White may then speculate with 13. Nxg5!?
13.Bxf6 gxf6 14.Nh4 Bg4
14...f5 15. Qh5 illustrates one of the big problems with 11...h6.
15.Qd2 Kh7 16.Ne3 Ne7 17.Kh1 f5?
The final mistake. This move had to be prefaced with 17...Be6, but after 18. f4 White would still be much better.
18.h3 Bxh3 19.gxh3 f4 20.Nef5 Ng6 21.Kh2 Qd8 22.Nf3 c6 23.Rg1 d5 24.Qe2 Qf6 25.Rg2 Rad8 26.Rag1 Rg8 27.Ng5+ 1:0
