The move is correct because white is already holpless in all variations. I tried autoplaying with long time control, both computers cant understand black is winning, but all the games black ended up winning. [D]r3r1k1/pp1q1p2/2p2npb/PPPp1bnp/3PpN2/2N1P1PP/1R1B1PBK/3Q1R2 b - - 0 19 Nikolic - Fischer 1968 The key move is 19 - Bg4!! The next Diagram was mentioned in Kasparov's My Predesessors, Kasparov said no computer can find the move here. [D]2r2rk1/pp3pp1/4bb1p/q2p1P1Q/3P4/2N5/PP4PP/1K1R1B1R b - - 0 17 Pillsbury - Lasker 1896 Key move 17 - Rxc3!! The next one here involves early sacrifice in the opening, there's no forcing line, just for iniative. This became the best played game in one of the 1990 Informator. [D]rn1qk1nr/1b3ppp/p2b4/3p4/P1pP4/5N2/2PNBPPP/R1BQ1RK1 w kq - 0 11 Geller - Dreev 1990 Key move 11. Bxc4!! Next one here people might already mentioned this to you, but just in case no one mentioned it, I'll post it here because its too good to miss. [D]8/8/4kpp1/3p1b2/p6P/2B5/6P1/6K1 b - - 0 47 Topalov - Shirov 1998 Key move 47 - Bh3!!
