can be a move hard to understand. If White captures a stone at instead, Black will live by intruding into the left and White's influence may not be sufficient.

Moves 27 to 36  

here is an important point for influence. If at instead, White will exchange a for b then take this point and Black's top central stones are floating.

Moves 37 to 38  

When Black defends at here, White continues to develop this corner exchange into a large scale fight with .

Joseki evaluation:

• Corner territory: Divided. Both have a small group, Black's being a bit larger.
• Influence: Black has influence towards the top side, cooperating well with his top right corner stone. White likewise has influence towards the bottom right. White has more influence towards the centre.
• Aji: White's position is somewhat thinner, with a and b as potential cuts. Black's top group however is a bit heavy.
• Sente: White has sente now, but considering the pattern evolved in one of "his" two corners, this is only to be expected.

Why not here with ?  

Although Black is crawling along the second line, perhaps White did not get enough from a left side where he invested 2 stones.

As we know, KataGo is not too fond of the pincer nor the counter pincer . The wedge of is perhaps a little inferior to a simple stretch, then , and are all blue moves?. For ...

Alternative for  

... KatatGo? suggests this variation. The original counter pincer stone is blighted but the original pincer stone is also badly affected by Black's influence. Black gets sente too to play the biggest corner reinforcement .

Alternative for  

For KataGo likes this much better. Notice how the two pincer stones are again disregarded by both as almost junk. Here White gets to play the big corner move .

 

Black's cut is favorable. would be better at A for a reason I can't explain. is not necessary, KataGo thinks and should try living on the left side already. is an outright mistake (2,1 pts) and White should in fact capture at B:

What if White captures (ctd)  

Variations can become pretty sharp now, with L&D situations on the left side but the point is that 1) White lives in the corner 2) White pressures the left side and is resilitent in the center 3) Black's connection at A is light and 4) White has the better chance to take the big sente at B first.
