Read a position
An isolated stone away from the edge has four liberties. A neighbouring opponent reduces that count. Connect to a friendly group to share liberties, and watch for groups left with only one.
A detail to notice
Before both players pass, resolve disputed captures on the board. This version counts remaining stones as alive and uses Chinese area scoring with 7.5 komi for White; it does not run a separate dead-stone negotiation.
