Kikashi: Forcing Moves
Kikashi is a forcing move — a stone your opponent almost has to answer — that gains you a small, free advantage before you turn to bigger things. Used well, kikashi squeezes little profits out of a position at no cost. Used carelessly, it throws away potential you'd have preferred to keep.

What kikashi is
A kikashi is a move that carries enough of a threat that your opponent must respond, but whose own stone you don't mind sacrificing afterward. You force the exchange, gain a touch of strength or reduce the opponent's shape, and then leave the kikashi stone behind and play the big move elsewhere. It's a way to profit in sente.
Good kikashi versus aji keshi
The line between a helpful kikashi and a wasteful one is fine. A good kikashi gains something real and doesn't strengthen your opponent more than you. A bad one — often called aji keshi — forces a response that fixes your opponent's weaknesses or uses up potential you could have exploited better later. Before you force, ask whether the exchange truly helps you.
Using kikashi well
- Play kikashi that your opponent must answer, or the move loses its point.
- Be ready to sacrifice the kikashi stone — it has done its job once answered.
- Don't force just because you can; each exchange removes options from the board.
- Save some forcing moves as future ko threats rather than spending them early.
Frequently asked questions
- What is kikashi in Go?
- Kikashi is a forcing move your opponent must answer, letting you gain a small advantage in sente before playing elsewhere. The kikashi stone is often sacrificed afterward, having already done its work.
- What's the difference between kikashi and aji keshi?
- A kikashi gains something real without over-helping your opponent. Aji keshi is a wasteful forcing move that fixes the opponent's shape or spends potential you'd rather have kept — a forcing move that costs more than it gains.
- When should I play forcing moves?
- Play kikashi when the exchange clearly helps you and your opponent must respond. Avoid forcing just because you can — each exchange removes options, and some forcing moves are better saved as ko threats.
