Alekhine vs Rosenberg, 1935 simul, White to play. Instead of 19 Qe2 Nxb2! White can try 19 Nd2 (intending Nc4) Nb6 20.Nb3 Qa4 21.Na1 Rac8 22.Qxa4 Bxa4 23.Bc2 Bd7 24.f3 (24.Nb3? Rxc2!) Nc4 25.Be1 Bc5 26.Nb3 Bd6 27.Bd2 a5! 28.Bd3! (capturing the Pawn loses material) b6 and Black is better but not by much.
<Calli: W Rosenberg. This game is from a simul which was a complete disaster for Alekhine....> Interesting research.
Crafty End Game Trainer link to the diagram: http://www.chessvideos.tv/endgame-t... You are white, drag and drop the move you want to make.
The White moves given above are courtesy of Crafty EGT playing colours reversed. After 19. Qe2 as played Black has 19...e4 as well as Rosenberg's 19...Nxb2. Clearly, something went badly wrong with White's opening: I finger 11.0-0-0
