During this lesson, we’ve seen how to manage this overplay during this joseki.
Punish the overplay
After black covers at 1, if white push and cut with 2 and 4, then the key move is the cutting at 5.
After this cutting white has no good option. If he connects at 6 then he cannot save the stone after the atari at 7 (otherwise black kills the left side).
