Fischer writes, "The innovation. Months before the I had showed this line to Benko and he suggested this innocent-looking move. Upon looking deeper I found that, horrible as White's pawn structure may be, Black can't exploit it because he'll be unable to develop his K-side normally. It's little quirks like this that could life difficult for a chess machine." 15...Rd8 16.Be3 Qxb5 17.Rxb5 Rd7 18.Ke2 f6 19.Rd1 Rxd1 20.Kxd1 Kd7 21.Rb8 Kc6 22.Bxa7 g5 23.a4 Bg7 24.Rb6+ Kd5 25.Rb7 Bf8 26.Rb8 Bg7 27.Rb5+ Kc6 28.Rb6+ Kd5 29.a5 f5 30.Bb8 Rc8 31.a6 Rxc3 32.Rb5+ Kc4 33.Rb7 Bd4 34.Rc7+ Kd3 35.Rxc3+ Kxc3 36.Be5! 1-0

In this position White has some forceful options like b5 or Bf2-h4, but since Black has no play I will just slowly improve my position and wait to see if he wants to make any bad moves ... 26.Kf2 Nb6? 27.Rac2 Nc8? 28.a4 b6? 29.Rb1 Ne7 30.Ra2 Na8? 31.Rba1 Rb7 32.a5+- After four totally unforced errors White can win by opening the a-file.

In this position Black has two possible plans: play defensively by moving the QN over to the kingside, c6, and Qd7-e6; or play more actively with Nd4 and f5, opening up the position. 12...Nd4 Benko choses the active plan (at first!). 13.Qf2 Ne8 14.0-0 Nd6 15.Qg3 Kh8 16.Qg4 c6? But, now he falters plays a move from the defensive plan. c5! was in order. 17.Qh5 Qe8? Benko is still mixing metaphors: now he switching back to the active plan, eyeing f5, but Ne6 was now the only move. 18.Bxd4 exd4 19.Rf6! Kg8 20.e5 h6 21.Ne2 1-0
