I have read a bit more about the game played, and perhaps it is not a
'madness', only a very risky sequence of moves, and much more risky if
you have in front one of the most solid players in the world, one with an
elite rating. Here is the game:
Nakamura,H (2660) - Gelfand,B (2724)
GM Biel SUI (10), 27.07.2005
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 e6 7.f4 Nbd7 8.Qf3
Qc7 9.0-0-0 b5 10.Bd3 Bb7 11.Rhe1 Qb6 (!?).
Here begins the main sequence:
12.Nd5 (?!) (Two pieces are in sacrifice now)...
Qxd4
13.Bxf6 (?!)(A new sacrifice)... gxf6 14.Bxb5 Qc5 15.Nxf6+ Kd8 16.Nxd7
(?!).
16...Qxb5 17.Nxf8 Rxf8 18.Qa3 Rc8 19.Qxd6+ Ke8 20.c3 Qc6 21.Qb4 a5 (!).
(It seems that Nakamura has not expected this one)...
22.Qxa5. White now has four pawns for the piece, but Black position is
safe, solid, and Gelfand plays the end with absolute precision...
22...Ra8 23.Qg5 f6(!) 24.Qd5 Qxc3+ 25.bxc3 exd5 26.exd5+ Kd7 27.Kb1 Ra4
28.g3 Rfa8 (!) 29.Rd2 R8a5 30.d6 Be4+ 31.Ka1 h5 (!) 32.h3 Bd5 33.g4 Rxa2+
34.Rxa2 Rxa2+ 35.Kb1 Rh2 36.Re3 h4 37.Kc1 Kxd6 38.f5 Rf2 39.Kd1 Rf3 0-1.
