If White then take the Bishop with his KtP the Queen will take the Pawn, giving check and attacking the White King's Rook at the same time. White can see the object of Black's play so in his next move he must try to prevent it. (See DIAGRAM XIV).

(14) White moves his King to Bsq. which puts him more under cover though it blocks his QR. He gains an advantage, however, for by moving from the diagonal commanded by the adverse QB, his own Knight is unpinned and can be moved if necessary.

Black takes the Knight with his Bishop, though he exposes his Bishop to capture in White's next move, but as the two pieces are of about equal value, the exchange is even.
