Return to parent joseki article: 4-4 point 3-3 invasion joseki

The 4-4 Point 3-3 invasion, hane is a common move that is a feature of the traditional 3-3 invasion joseki as well as double-hane joseki. It can be used to create a wall or to take territory by capturing the corner in gote.

Historically, it was the most common way to play the 3-3 invasion. However, ever since the AI era, the traditional joseki has come under scrutiny for various weaknesses. Currently, professionals and strong AI programs only play this move if they plan take the corner with the double-hane variation.

Discussion

Why isn't the hane-extend played anymore?

When to play the double hane?

When to play the inside hane?

What if white plays the hane on the wrong side?

Changing the order  

If White tries to reverse the order in the hane-stretch variation by playing W1 before W5, then Black may punish with B4. This lets Black shut White into the corner (particularly as a is Black's sente). White ends up with a smaller corner (than in the joseki) and Black may be in a position to make territory on the left. The only positional disadvantage for Black is the aji of the cut at b. However, it general pales in comparison to White's initial loss and Black's overall gain. See 4-4 point 3-3 invasion, W reverse playing order.
