King's Indian Bishop Fork Chess Puzzles
The King's Indian Bishop Fork is a tactical motif that appears in King's Indian Defense structures when a bishop, often on g7 or h6, attacks two enemy pieces or a piece and a key square at the same time. For example, after the typical ...Bg7 setup, the bishop can create a fork on the long diagonal by hitting the queen and rook, or a king and major piece, once lines open. It is not a fixed opening line, but a recurring tactical idea tied to the bishop’s diagonal pressure in the King's Indian.
To spot this motif, look for moments when the bishop’s diagonal is cleared by a pawn break such as ...e5 or ...f5, or when White’s pieces cluster on dark squares in front of the king. The fork usually becomes possible after a sacrifice or exchange opens the bishop’s line, so count whether the bishop can attack two targets immediately after the move. Use it by preparing the diagonal first, then timing the bishop move so both targets are vulnerable on the same turn.
