joshi tm: I think 11.dc it´s a ilegal move because any piece can go to square c6 and if white could play en-passant then the white pawn would go to c6. You suppose 11.dc is a legal move, then as consecuence black could play 11...bc and a black pawn could land in the square c6. c6 is closed until the end of the game so 11.dc it´s, in my opinion, a ilegal move.
