Ponpon Knight (ポンポン桂 or ぽんぽん桂 ponpon kei) is a surprise Static Rook attack position used against a Ranging Rook opponent.

The ponpon in the name is an onomatopoeia ( mimetic) sound effect of the Static Rook player's right knight jumping twice to start an early attack.

The position was originally used against a Fourth File Rook opponent. However, a more recent variation was developed to counter a Cheerful Central Rook opponent.

The strategy is not used by professional shogi players but can be found in amateur shogi.
