8.Nxe5= remains equal. Bxe5 9.Qxd8+ Kxd8 10.Bg5 8...0-0 8...Neg4!-+ ...0-0 is the strong threat. 9.Bc4 9.e5 Bxe5 10.Nxe5 Nxe5 11.Nf3 Qxd1+ 12.Kxd1 9...Ne3 9...0-0 10.Qe2 Re8 9.Be2 9.Nxe5 Bxe5 10.Qc2 White should play 10.Nf3 Qxd1+ 11.Kxd1 Nxe4 12.Be3 9.Nxe5 Bxe5 10.Be2 9...Qe7 9...Nfg4-+ White must now prevent ...Ne3. 10.Nc4 Nxf3+ 11.gxf3 Qh4+ 12.Kd2 Nf2 Better is 9...Nxf3+-+ 10.Bxf3 Ng4! 11.Bxg4 Qh4+ 12.g3 Qxg4 13.Qxg4 Bxg4 10.0-0
10.Nxe5 is the only way for White. Bxe5 11.0-0 10...Neg4? 10...Nfg4!-+ and Black stays clearly on top. Threatens to win with ...Ne3. 11.Nxe5 Ne3 11.Nc4 Nxe4 11...Bc5+ 12.Nd4 Rd8 12...Be6 13.h3 Bxc4 14.Bxc4 Ne5 12.Nxd6= Nxd6 13.Nd4 13.Re1!= remains equal. 13...Ne3 14.Bxe3 Qxe3+ 15.Kh1 Bd7 16.Bf3 Qg5 17.Qb3 17.b4 17.Qc1 Qxc1 18.Raxc1 17...c6 Black should try 17...c5 18.Ne2 Rae8 18.Rae1 Rae8 19.Qa3 19.Qa4 was called for. 19...Nb5 19...c5 Strongly threatening ...Nc4. 20.Nb3
20...Bb5! 21.Rxe8 Rxe8
19...c5-+ And now ...Nc4 would win. 20.Nb3 Bb5 21.Rxe8 Rxe8 20.Nxb5 Qxb5 White is in trouble. Black has strong attack. 21.b4 a6 22.Qb2 Be6 22...Rxe1 feels hotter. 23.Rxe1 Be6 24.Rd1 Re8 25.Qd2 h6 23.Be2 23.a3 was worth a try. 23...Bc4 23...Qg5-+ 24.Bd3 g6 24.Bxc4 Qxc4 25.h3 Re6 26.Rxe6?? -
26.Kg1 26.Kh2 26...Qxf1+-+ Not 26...Qxe6? 26...Qxf1+ -#37 27.a4 Weaker is 26...Qxe6 27.a4 27.Kh2 fxe6 Accuracy: White = 18%, Black = 11%.
