is the correct play, as it puts the Queen in a position to take three of White's forces: QKt., KB, and KR. Of the three, the KB is protected by the KR and the QKt. is protected by the QKt.P and the QB so they are both safe. The KR is not protected, nor is the pawn on QKt7 so White must take steps to protect the more valuable, i.e., the KR.
16 | Resigns. |
(16) White's Pieces and Pawns are now in such a poor position that even if he did try to protect his King's Rook, he would gain so little that he could not possibly hope to win the game and, in consequence of this, he resigns and Black scores the game as won.
The student should notice that in this game, in spite of the opening moves on White's part, he has been on the defensive side all the time. Black, on the contrary, has made the attack with such success that his adversary resigned without even waiting for the checkmate.
