Moscow Variation Bishop Fork Chess Puzzles
The Moscow Variation Bishop Fork is a tactical motif that can arise in the Sicilian Defense, Moscow Variation, after White checks with 3.Bb5+. In the typical position, White’s bishop on b5 creates pressure on the c6 knight and can later fork two valuable targets if Black’s pieces are placed carelessly. For an intermediate player, the key idea is that the bishop is not just checking the king—it may also be setting up a double attack on the king and queen, or king and rook, from a strong diagonal.
To spot this motif, watch for positions where Black’s king is still uncastled or where the queen and a loose piece sit on the same diagonal as White’s bishop after the Moscow move order. The fork usually becomes possible when Black responds with a natural developing move that leaves c6, d7, or e6 underprotected, allowing the bishop to hit two targets at once. Use it by keeping the bishop active on b5 and timing the check so Black’s king move or interposed piece creates a tactical weakness.
