If you ask chess players what was Fischer’s defence against 1.d4, most would say the King’s Indian Defence (KID). A few would also say the Gruenfeld as well (remember the “Game of the Century” they might yell out).
But Fischer also had a third option, one which he used for surprise and special occasions. That defence is known as the Benoni and is characterized as 1.d4 Nf6 2.c4 c5. Black intends to strike on the queenside and is willing to sacrifice a pawn to gain a powerful attacking position from that side of the board.

1.d4 Nf6 2.c4 c5 3.d5 e6 4.Nc3 exd5 5.cxd5 d6 6.e4 g6 7.Nf3 Bg7 8.Bg5 (Recent experiences with this move are discouraging.) 8…h6 9.Bf4 g5 10.Bc1 (Understandably, White dislikes both trading the Bishop for Knight by 10.Bg3 Nh5 or 10.Be3 Ng4 and 10.Bd2 interfering with his intended Nd2. So the Bishop has, if one may put it so, achieved a but less than nothing.) 10…O-O 11.Nd2 Nbd7 12.Be2 Ne5 13.Nf1 (Apparently hoping to exploit the hole on f5, White again loses time. He ought to castle instead.) 13…b5 (An excellent pawn sacrifice. Here Fischer shows his extra sense for grasping any attacking possibility.) 14.Bxb5 (Declining the sacrifice by 14.Ng3 is no better because of 14…Qa5! 15.O-O and Black has either 15…b4 16.Nb1 c4 17.Nd2 c3 18.bxc3 bxc3 etc., or 15…Bd7 followed possibly by 16.a4 b4 17.Nb1 c4 18.Nd2 Rfc8 19.Qc2 Qc5 etc.) 14…Qa5 15.Ng3 (Black wins on 15.Bd3 Nxd3+ 16.Qxd3 Nxe4 17.Qxe4 Bxc3+ 18.Bd2 Bxd2+ 19.Nxd2 Ba6.) 15…c4 16.O-O Rb8 17.Qa4 Qxa4 18.Bxa4 Nd3 (The swap of Queens has changed the situation, but little. Black has a strong initiative for his Pawn.) 19.Bb5 (A better defense is 19.Rb1 Then 19…Ng4 threatens 20…Bxc3 but is met by 20.Bc2.) 19…Ng4 20.Nge2 Nxc1 21.Raxc1 Ne5 22.b3 cxb3 23.axb3 a6 24.Ba4 Nd3 25.Rc2 f5 26.Ng3 (White makes matters worse: 26.exf5 Bxf5 27.Rd2 is necessary.) 26…f4! 27.Nge2 f3 28.Ng3 fxg2 29.Kxg2 Bg4! (Now Black has positional advantages which must win one way or another.)
30.Nf5 (White loses a piece: but the plausible 30.f3 also loses quickly because of 30…Bxf3+! and 31.Kh3 31…Nf4# or 31.Rxf3 Ne1+ or 31.Kg1 Bd4+ etc. 30.Nd1 may hold out longer but not really for long.) 30…Nf4+ 31.Kg3 (There is no difference after 31.Kg1 but 31.Kh1 allows mate in two.) 31…Bxf5 32.exf5 Bxc3 33.Kf3 (Or 33.Rxc3 Ne2+, and the damage amounts to a full Rook.) 33…Be5 34.Ke4 Rb4+ 35.Rc4 Rfb8 36.f6 Kf7 37.Kf5 Rxc4 38.bxc4 Ne2 39.Re1 Nd4+ 40.Kg4 h5+ 41.Kh3 Kxf6 0-1

[This was the first time ever that Fischer beat Spassky in a game. Immediately following this victory Fischer went on a rampage to win the title.]

[It is difficult to state what is the best move for White here. One try is 13.h3 h4 14.a4, placing some pressure on the wings.

Aleksey Ivlev (2259)-Daniil Yuffa (2527), Russia Blitz Ch., Sochi, Oct. 2 2017 continued instead with 13.Nf3 (On the whole, this looks like a better move than 13.h3 as above.) 13…Ne5 14.Nxe5 Bxe5 15.Ne2 h4 16.Bf4 Bxf4 17.Nxf4 Qg5 18.g3 h3 19.f3 Bd7 20.Rae1 h5 21.Kh1 Re7 -/+ 22.Nd3 Rae8 23.e5 Bf5 24.f4 Qg6 25.Re3 dxe5 26.fxe5 Bxd3 27.Qxd3 Qxd3 28.Rxd3 Rxe5 29.d6 Re2 30.Rd5 Rf2 31.Rg1 0-1.]
