Winning Condition

“Keep in mind your opponent’s winning condition” is strategic advice by youtuber dwyrin, usually to be applied when ahead:

Keep asking yourself “Under which condition(s) can my opponent still win?”

When you are ahead, your opponent usually only has a few winning conditions, such as making a big territory in the one place where this is possible, or killing a group.

Focusing on preventing that winning condition is a good way to win a won game.
