Moscow Variation Empty Square Sacrifice Chess Puzzles
The Moscow Variation Empty Square Sacrifice is a tactical motif that appears in the Moscow Variation of the Sicilian Defense, usually after 1.e4 c5 2.Nf3 d6 3.Bb5+. It refers to a sacrifice that clears or “empties” a key square so a piece can invade, often creating a direct attack on the king or winning material by force.
To spot it, look for positions where the bishop check on b5 has already forced a specific pawn or piece response, leaving a critical square undefended. The sacrifice is most effective when the opponent’s king is still in the center or when the move that captures the sacrificed piece opens a file, diagonal, or entry square for your queen or knight.
