Chess Puzzle #4msAO — Beginner, Black to move, middlegame

Position

White: king g1; queen b8; rook e1; bishop g4; pawns a2/f2/g2/h3. Black: king h7; queen f6; rook c2; bishop f7; pawns e6/g7/h6. White is ahead by 1 point of material. Black to move.

Solution (2 moves)

1. Opponent setup: Qb1 — queen b8→b1. Now Black to move.
2. Best move: Qxf2+ — queen f6→f2, captures pawn, gives check. Opponent replies Kh2 (king g1→h2).
3. Best move: Qxg2# — queen f2→g2, captures pawn, delivers checkmate.

Why this works

Black's queen on f6 dominates the kingside after White's queen retreats to b1. The move 1...Qxf2+ checks the king on g1 and forces it to h2—the only legal square, since f1 is controlled by the queen and h1 is also controlled by the same piece. After 2.Kh2 is forced, Black delivers 2...Qxg2# because the queen on g2 checks the king on h2 with no escape: h1 is controlled by the queen, h3 is blocked by White's own pawn, and g1 is also controlled by the queen. White's bishop on g4 and rook on e1 cannot reach g2 or defend h1 in time. The white king is completely cut off.

What to practice

In positions where the enemy king is already restricted by its own pawns, look for forcing checks that drive it into the corner. Black's queen exploits the h3 pawn as a trap—by checking from f2, the queen forces the king to h2, and then g2 becomes an unstoppable mating square. The pattern: a queen check that narrows the king's options, followed by a quiet capture on an adjacent square that seals all exits. This is a classic two-move finale when the defender's pieces are far from the kingside.

Tactical themes

endgame, mate, mate in 2, short. The combination ends with Qxg2# delivering checkmate.
