Offering the Pawn sacrifice Ktxc3; (10) Pxc3, Bxc3 with the view to attacking by (11) R-c1, etc., as previously indicated. Black prefers to direct his attack against g5.
(9) … Ktxg5 (10) Ktxg5 Pxd4 (11) Kt-b5
(11) Pxd4 would lose a piece on account of Pxc4, attacking the Bishop on d3 and the Knight on g5. Black could now win a Pawn by taking on d3, but this would be very dangerous as it would open the f-file for White's Rook.
(11) … Kt-c5

DIAGRAM 71.
The position is getting very complicated indeed. The first possibility which White will consider is (12) Kt-d6+; but after K-e7 there seems to be no satisfactory continuation. For instance: (13) Q-C2, Ktxd3; (14) Ktd6xf7, R-f8 winning two Knights for the Rook. Or: (14) Ktxc8+ ?, Ra8xc8; (15) Qxd3, Pxc4 winning a piece. Therefore, White has no alternative but to retire the Queen.
(12) Q-c2 Ktxd3 (13) Qxd3 P-a6
