The lesson video is the following
Main position
During this lesson, we’ve seen why AI prefers to play at 10 instead of connecting at A.

White approaches
When white approaches at 1, black can choose to tenuki.

In this case, white can capture the two stones but black is quite strong in the outside.
If black doesn’t like this result, he can respond the approach with 2 in the next diagram.

White overplay
White cannot cut directly with 1.

Black can calmly play 2 and 3, and white is dead.
Old variation
AI really hate the connection with the marked stone.

If black tenuki, then white can play up to 6. Then if the ladder (of stone 5) is working for white, he can connect at A. Otherwise play B and fight. In both cases, white has a good position to fight.
