3-5 point 3-3 approach

3-3 approach  

here is an alternative to the common approach at a. It can have a strategic meaning, for example to avoid being pressed into a low position (White a, Black b).

A common transposition

Black's answers  

The normal answer is - this transposes to the 4-5 point 3-3 invasion.

The attachment

Attachment  

The outward hane is almost the only move here. A gobase search reveals 48 pro games.

Variation 1  

If here, Black will cut the side he doesn't want. Since this is the same as 4-5 Point, 4-3 Approach, Outside Contact but one line lower, this is likely to be b, in order to capture in a ladder. Therefore, White will usually not choose this variation if the ladder works for Black.

Variation 2  

This variation avoids the ladder but remains low. aims at a or b.

Variation 3  

here is a bit rarer as a search result. White has a small corner but can take sente.

Strategic reasons to choose this move

Example  

For example, is more common in pro games than Black at a. The low stone can cause Black to dislike being pressed down.

Continuation  

Black's idea is to play tenuki after here. White at a now makes thickness facing .

For White ignoring the cover play by Black, see 3-5 point 3-3 approach cover, tenuki.

3-3 approach  

White is Yi Ch'ang Ho. Black is Yi Se-tol.

Continuation  

is fine technique to create shortage of liberties. and concentrate on the two upper white stones.

Continuation  

instead of a avoids strengthening White. and focus on stabilizing this group and take the initiative. switches to the top, establishing a connection between his influential group and his corner stone.

Variation  

is possible, but it follows the low 3-3 point move with an even lower second line move. This may be OK for White if there is a strong White position on the left side.
