提示
查看提示
Block every three-in-a-row chance instead of trying to win.
为什么有效
The goal shifts from winning to simply preventing a loss. You need to place your marks where they stop the other side from ever completing a line. With the grid already set up, marking the right blocking cells leaves no possible tic-tac-toe, which forces the game to finish as a draw.

That cell is the strongest spot because it shuts down the middle paths the other side would otherwise use to build a row.
