White: Peter Bereolos
Black: GM Gregory Kaidanov
Land Of The Sky, 1998
Round 3, Board 1
1.d4 d5 2.c4 e6 3.Nf3 Nf6 4.g3 dxc4 5.Bg2 Nc6 6.Qa4 Bb4+ 7.Bd2 Nd5
After the game, Kaidanov asked me where my knowledge of theory ended. I had to somewhat embarrassingly admit that this was a new move to me. I was only familiar with the move 7...Bd6, which had occurred in a game between Karpov and Kramnik played shortly before this one.
8.Bxb4 Nxb4 9.a3 b5 10.Qxb5 Nc2+ 11.Kd2 Nxa1 12.Qxc6+ Bd7 13.Qxc4 c5 14.Nc3?!
The first new move, but not a very good one. The normal move is 14.Qa2 with a very double-edged game. White will obtain two pieces for his rook but his development will be a bit backward and his King will be somewhat exposed in the center. Interestingly, a few months later, Kaidanov chose to play the White side of this line in a must win situation versus Goldin in the final round of the World Open. However, things did not turn out well for him there.

Black hits at the weaknesses at b2, b3 and d4.
15.b4 cxd4 16.Nd5
Desperation, but there was not much else to do. 16.Nxd4 is met by 16...Rc8 and 17...Qxd4. 16.Ne4 Rc8 17.Nc5 (else ...Nc2) Rxc5 18.bxc5 Qb2+ 19.Kd1 Bb5 also looks grim for White. My best hope now is somehow pick up the d4 pawn and the Na1 which would give me two pawns for the exchange and good chances to hold if I can get my King to safety. It looks like White may have a chance to pull this off because of his multiple threats, but Kaidanov shows that the White pieces are not on good squares.
16...exd5 17.Qxd5 Qh6+
A good move covering g7 in case of Qe5+ and highlighting the uncomfortable position of the White King.
18.Ng5 Nb3+ 19.Kc2 0-0 20.Kxb3 Rad8 21.Qc5 Rc8 22.Qxd4
Achieving parts one and two of my goal, but my King is not safe.
