Kirichigai

A cross-cut (kirichigai) occurs when two players simultaneously cut into each other’s groups, creating an intersecting pattern of stones. This move typically leads to immediate fighting, as both sides must decide how to handle the cuts and potential weaknesses. The key feature of cross-cut is that it does not provide an immediate advantage but instead initiates a high-stakes battle for influence, liberties, and shape.

Strategic Considerations

• Cross-cut is a common feature in middle-game fighting and often leads to complex reading scenarios.
• It can be used both offensively, to disrupt an opponent’s structure, and defensively, to create counterplay.
• Handling cross-cut properly involves choosing between extending for stability or sacrificing a stone to complicate the situation.

Because of its aggressive nature, cross-cut requires careful calculation. If misplayed, it can result in losing control of the fight, but when executed correctly, it can split the opponent’s groups and force favorable exchanges.
