tright Ruy Lopez, Schliemann Defence rd kd bd rd nl pd pd nd pd pd qd pd pl pl pl pl pl ql pl pl rl bl kl rl Common moves: 11...Qc5 - German Variation 11...Qxf4 - Grandmaster Gambit AcceptedBlack's queen is attacked by an unprotected pawn. There are two plausible queen moves: 11...Qxf4 accepts the gambited f-pawn, which then allows White to solve most of her problems with the developing move 12.d4 before the a7-knight needs to be extracted to b5. White remains a pawn up and although Black can point to a passed pawn on e4, it's isolated and immobile. 11...Qc5 attempts to imbalance the position a little by grabbing the c2-pawn instead of the f4-pawn, thus isolating White's d-pawn. Sadly, 12.Nb5 Qxc2 13.d4! is still possible, and with 13...Qc6 not sufficing to defend the e-pawn because of 14.d5 (14...Qxd5?? 15.Nc7+) the queens will have to come off and White is a clear pawn up again. Those two lines are Exhibits A and B for the prosecution's case that 9.Nxa7+ busts the whole Classical (7...Qg5) Schliemann Defence. Other moves: 11...Qf5 was tried a bunch of times between 2011 and 2013, with no success whatsoever. White calmly retreats with 12.Nb5 and then has pawn majorities on both sides of the board. 12...O-O-O 13.a4 gets the queenside one rolling. Similarly 11...Qh4+. It's not clear how Black benefits from provoking g3 before retreating the queen to e7. 11...Qa5 was suggested on the ChessPublishing.com message board, but it's completely refuted by Solodovnichenko's 12.Nb5 Bc5 13.b4! Bxb4 14.Rb1 O-O-O 15.Na7+! Qxa7 16.Rxb4 when White's attacking chances are as great as Black's. Ruy Lopez
