What could be better than that? 9...Qe6 could be better than that. Catching the opposing king in the centre is half the fun of sacrificing pawns, and here 10.O-O?? would unprotect the White queen and so drop a piece to 10...d6. 10.d4 is surprisingly popular given that it doesn't actually get out of the pin! (It does help develop a piece though.) Black has tried various moves to claim some initiative; Radjabov's choice is 10...Bf6, 10...O-O is also obvious, 10...a5 prepares ...Ba6 hitting the queen, 10...c5 immediately challenges the d-pawn. Karjakin tried 10.Nf3 against Radjabov, which does get out of the pin. White loses castling privileges after 10...Qxe2 11.Kxe2 but can easily castle by hand with Re1 and Kf1. Dominguez Perez tried 10.Nc4 against Fressinet, to similar effect. 10.Qe3 is a radical solution tried by Frolyanov and Timofeev. Black has ...Ba6, ...Bf6 and ...c5 options after mutual kingside castling. Ruy Lopez
