White: Peter Bereolos
Black: GM Dimitry Gurevich
World Open, 1985
Round 1 Board 11

1.Nf3 c5 2.c4 b6

Heading for a hedgehog I thought.

3.g3 Bb7 4.Bg2 g6 5.Nc3 Bg7 6.b3 d5 7.cxd5 Nf6

Now it looks like I'll be playing the hedgehog!

8.Bb2 Nxd5 9.0-0 0-0 10.Rc1 Nc6 11.Qc2 Ndb4 12.Qb1 e5 13.a3 Na6 14.d3 Qd7 15.Rfd1 Rad8 16.Ne4 Rfe8 17.Bc3

Angling for b4, but Black soon gains an advantage. 17. e3 controlling d4 is probably better.

17...Nd4 18.Re1 f5 19.Ned2 Nb5 20.Bb2 e4

White's pieces are improperly placed to cope with this breakthrough.

21.Ng5 exd3 22.Bxb7 Qxb7 23.exd3 Bxb2 24.Qxb2 Nd4

White has managed to preserve material equality, but not for long. The weaknesses at d4, d3, and f3 give Black a clear advantage. It is hard to make a suggestion for White in this position.

25.Nc4 Rxe1+ 26.Rxe1 h6 27.Ne6 Qe7 28.Qd2?

[28.Nxd8 Qxe1+ 29.Kg2 Qe7-+]

28...Nf3+ 0:1
