Chess Puzzle #EM38w — Advanced, White to move, middlegame

Position

White: king g1; queen e3; rook f1; bishop d4; pawns a3/c3/f4/g5/h3. Black: king g8; queen b2; rook b8; bishops e7/f7; pawns a6/d5/g7/h7. Black is ahead by 2 points of material. White to move.

Solution (2 moves)

1. Opponent setup: Qxa3 — queen b2→a3, captures pawn. Now White to move.
2. Best move: Qe5 — queen e3→e5. Opponent replies Bf8 (bishop e7→f8).
3. Best move: Qxb8 — queen e5→b8, captures rook.

Why this works

After Black's 34...Qxa3, White's queen on e5 targets both the bishop on f7 and the rook on b8 along the long diagonal and fifth rank respectively. When Black defends with 35...Bf8, the bishop abandons e7 and loses control of the b8 square. White's 36.Qxb8 simply captures the undefended rook. Black cannot recapture because the bishop on f8 no longer reaches b8. The decisive point is that Black's defensive try 35...Bf8 actually worsens the position by moving the only piece that could contest b8; any other move (such as 35...Kh8 or 35...g6) allows 36.Qxf7, threatening mate on g8 while winning the bishop.

What to practice

Recognize positions where a single piece defends multiple critical squares. Here, the bishop on e7 protected both itself and the rook on b8. By attacking both targets at once with the queen (a double attack on f7 and b8), White forces Black into a choice: moving the bishop to safety leaves the rook undefended, while defending the rook abandons the bishop. This deflection pattern—forcing a defender to choose between two targets—is the core of many middlegame combinations.

Tactical themes

advantage, middlegame, short. The key move is Qe5.
