|Chess Middle Game Winning Position|
Here is a situation that can arise during the middle of a game.
It is Black's move, and thinking that White merely threatens to play Q - R 6 and to mate at K Kt 7, Black plays 1 ... R - K 1, threatening mate by way of R - K 8. White now uncovers his real and most effective threat, viz.:
1 ... R - K 1; 2 Q × P ch, K × Q; 3 R - R 3 ch, K - Kt 1; 4 R - R 8 mate.
