White, having just promoted a pawn to a queen, knows a secret that black is about to learn the hard way.|The queen's power blossoms fully in the endgame where it can attack seemingly everything at once.|The side with a queen can force his opponent's king to assume a post directly in front of his own pawn. Then, when the pawn cannot be advanced, the queen's king will approach to eventually pick off the pawn. This forcing maneuver is performed as often as necessary.|The queen may also blockade her opponent's pawn directly, if permitted the opportunity. } 1. Qf4+ { There are several moves that win for white, 1. Qb4+, 1. Qf2, or even 1. Qd6+ for example. The secret is that this position is won for white. The method is simple. White aims to force the black king to assume a post directly in front of the pawn. Then, when the pawn cannot be advanced, the white king will approach to eventually pick off the pawn. } 1...
