(2200) - IM Glazer,Helmut (2470) [B74]
2nd NAPZ, 1994
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.Be3 Bg7 7.Be2
This was my first international tournament. I was sure a 2470 IM was very strong,
and knew lots of theory which was not readily available. So White avoids
the "modern" Yugoslav attack and plays an "old-fashioned" system. Remember
that this was 1994, and that most players (myself included) did not have home
PCs, chess-playing programs, or computer databases.
7...Nc6 8.0-0 0-0 9.Nb3 b6?!
According to theory, Black can equalize by trading off pieces on c4 or
g4 after 9 ... Be6; 10 f4, Na5 or Qc8. But in a tournament with 7 2400+ players, and
a handful of unrated (nominally 2200) players such as myself, it could make sense
for a 2470 Black to avoid exchanges and try for more than equality.
10.f4 Bb7 11.Bf3 Rc8 12.Qd2 Qc7?!
Very passive. Black needs counterplay, and should try 12 ... Qd7 with the idea of
Ng4, or 12 ... Nd7!? with the idea of 13 ... B:c3 and if 14 Q:c3, then Nce5.
13.Rad1 Rfe8 14.Rfe1 Nd8
Black's avoidance of theory and exchanges isn't working out. The natural-looking
14 ... a6 just creates a weakness on b6, and White increases his advantage by Qf2 or
Na4 or Nd5 forcing ...N:d5.
Now b6 is shielded by Nd4, but White has another idea.
16.Bf2 b5 17.e5!
This must be the right idea. White, unlike Black, has all his pieces developed,
and ...Nd8 interferes with the cooperation between Black's Rooks and has left e5 temporarily undefended. In other words, the tactics "should" work, but still need to be calculated.
17...Bxf3 18.exf6 b4!

24.Rxe6 Re8 25.Qd5! Kh8 (25...Bxc2? 26.Rxg6+! Kh8 27.Rxg7! mates quickly) 26.Qxd1+-]
19.Rxe7 Rxe7 20.fxe7 Qxe7 21.Nxf3 bxc3 22.bxc3 Nb7 23.Qd3 Rxc3
Probably best. After 23 ... a5, White has a combination of advantages: extra
doubled pawn, two weak Black pawns, stable center squares for White's pieces.
But now the White a-pawn is dangerous.

41.Ke1 Bc3+ 42.Kf1 fxe6 43.Nxe6+ Kf6
Black has material equality but White is winning due to the dual threats: against the
King and to trade Queens and win with the passed a-pawn.
