Assuming you play 11.Bd3, 11...Ne7 doesn't look bad if all you're trying for is a draw. Kramnik and Topolov have played this move to a draw against very strong GMs (Anand, Svidler and Shirov). Also, it's the main line, so I would be surprised if it is actually "lost". [D]r1bqk2r/4npbp/p2p1p2/1p1Np3/4P3/N2B4/PPP2PPP/R2QK2R w KQkq - 0 12 Now, true, very few GMs LOSE from this position as White. The highest-ranked one that I can find was ranked 2590. But I would definitely say that Black has excellent drawing chances. It seems like the one move that has the most options for White is the 15th. My database shows seven different moves that have been played here. Only two of them (Qf3 and cxb5) score better for White. One move (f3) shows equal scoring for White and Black. And the four other moves (Qe2, Qh5, Re1 and exf5) all score better for Black.
