This game comes to us from 1970 Beograd between Bent Larsen and Boris Spassky. Larsen played a hypermodern opening as white, and things just didn't work out as he wanted to. White has just played 14.Rg1 when Spassky made chess history by responding with 14...Rh1! Fantastic move, and definitely one that should be included in chess' greatest moments. Spassky took advantage of his weak but advanced G pawn. Larsen played 15. Rh1 g2 16. Rf1 giving back the sacrificed rook ( 16. Rg1 Qh4+ 17. Kd1 Qh1 18. Qc1 Qg1+ 19. Kc2 Qc1+ Bc1 and black will win ). Spassky continued his attack with 16...Qh4+ 17. Kd1 Gf1(Q)+ and Larsen resigned. If 18. Bf1, then 18...Bg4+ 19. Kc1 Qe1+ 20. Qd1 Qd1 mate.
