Forcing stalemate

This tactical procedure is used by the side which has the disadvantage and it usually involves a piece sacrifice. A player uses this maneuver when he realizes that he has no chance of recovering the gap between himself and the opponent.

Black is in a lot of trouble. White has an extra knight and rook and the pawns from b5 and d5 are dangerously close to the promotion squares. But Black has the resources to end the game a draw. He moves 1....Q:d5!. White is forced to capture the queen 2. N:d5 (otherwise after the white king would move on the h column 3...Rh7 checkmate). You can see now that the king would be stalemate if it weren't for the rook at f7, but that can be easily fixed: 2... Rf2+ 3.Kh1 Rh2+ 4.Q:h2 and now Black is not able to move any of the piece.

Normally, in a game like this, Black wouldn't stand a chance. But in this situation he is able to force a stalemate by sacrificing both his queen and his rook

Do you think is possible for White to end the game a draw? White has its turn to move. You can see that the black pawn is one square away from being promoted and that the white rook can't stop it by moving at c7. The answer is 'yes' and comes in the form of a very ingenious maneuver. 1. Rb7+ Kc8 (if 1... Ka8 than 2. Rg7 Qc1 3. Rg8+ Qc8 4. R:c8checkmate) 2. Rb5 Qc1 3. Rc5+ Q:c5 stalemate.

An intriguing example that shows you just how spectacles this tactical maneuver can be
