RUY LOPEZ TRANSPOSITION
BERLIN D. (Centre V.) to STEINITZ D. (Side V.)
White advanced a forceful QPawn to the centre to form a joint attack against Black's KP.
Black sets his Queen's Pawn on Q3(d6) to switch his KP defence and free his QB - a poor move here, for he can lose a pawn in ensuing exchanges. B-Alt.
