life in sente

  Difficulty: Intermediate   Keywords: Life & Death

In terms of life and death, the best outcome for a group of stones is life in sente.

A move is sente if the opponent has to answer it, so the player who plays it will maintain sente after the exchange. Life in sente requires the move which both requires a response and causes a group of stones to live.

Taking away the opponent's base while making good shape, removing aji while threatening an attack, and playing Sabaki moves to settle a group all derive from the desire to live in sente.

Example

Black lives in sente

To protect against black capturing the corner by moving at a, white must respond to B1. Black then plays elsewhere; black can capture marked white stones whenever he wants.

[Diagram]

Black lives in gote

Black captures white's stones, but white doesn't need to respond to this move, and can play elsewhere.
