Most of Polugaevsky's rivals had mentally chalked up a zero for him as ...Rc8 is impossible, but Polugaevsky has prepared a fine resource   20...Nb3+! (20...Rc8 21.Qxc6+ leads to mate ) 21.Kb1? Already a decisive mistake ( after 21.axb3 Black's attack is dangerous but White should be able to defend - analysis suggested a draw as the most likely result ) 21...Na5 22.Rd4 Rc8 23.Red1 g5 24.Bxc6+ Qxc6 25.Qd3 Be7 26.Be1 O-O 27.Bxb4 Bxb4 28.Rxb4 Nc4 29.b3 Nxe5 30.Qe2 Qc3 31.Re4 Nc6 32.Rd3 Qa5 33.Rh3 Nb4 34.c4 Rfd8 35.a4 Qf5 36.Rf3 Qg6 37.Kb2 Qg7+ 38.Kb1 Rc6 39.c5 Nd5 40.Rc4 Nf4 41.Qb2 Rd1+ 42.Ka2 Qf8 43.Rfc3 Qd8 44.Rc2 Nd3 45.Qc3 Qd5 46.Ka3 Ne5 47.Rb4 Rd3 48.Rb8+ Kg7 49.Qb4 Rd1 50.Ka2 Ra6 51.Rb6 Rd4 52.Qxd4 Qxd4 53.Rxa6 Qd3 0-1
