Ending and counting
Two consecutive passes close the game — the signal that nothing worthwhile remains. Area scoring (Chinese, the default here) counts the empty points you surround plus your stones on the board, so an extra stone inside your own area costs nothing; territory scoring (Japanese) counts surrounded points plus prisoners, so the same stone would cost a point. White then adds komi, 7.5 here, the fee for moving second — on even boards it is why White rarely wins by much. The counting habit to build: read a finished board as architecture, walls with the rooms behind them, and sweep every boundary once before passing. This board is the clean version: two full walls, two pure strips. Click any empty point inside White's territory.
