Hi, I could use some help to spot where I lost this game :



The first 25 moves where played at the speed of light, but it's the same as a pro game I studied recently. White started to vary at 26.

I somewhat allowed him to grow too big after , but I can't see what I could have done instead. I mean, I can't split both sides... Or did I lose even before 80 ? If so, where ?

Was the joseki you played in the lower left what the pro chose?

27+33: These moves seem unduly friendly when white is struggling to live in an area of the board where you outnumber him. The more you let him build strength without any impediment, the more the attack at C8 or C9 becomes a problem for you.

I think that you should hane at 27, and if not, you must at 33.
Are you concerned about the respective crosscuts at G16 or H16? I think that you should welcome such a fight. His cutting stone has your N18/17/16 wall to worry about.

51: This is aji keshi. More than that, it is attacking from your stronger formation and forcing him to build strength near your weaker group. Generally, it is best to do the reverse: to attack by building your weaker group in sente and forcing him toward your stronger group.

67: Again, aji keshi.

69: A third time. Now you can't turn at F7 and force your way through, whereas you could have before.

77+79: This basically gives up on the whole idea of attacking white. Black is temprarily ahead in territory, but the black stones are tapped out. All of the strong black formations face nearly invulnerable white formations. The future belongs to white.



The coronor's report looks like this:
A) A wall from N18 to N15. Used to make territory.
B) A wall from C11 to J11. Got capped. Scrambled for life on the left side.
C) Strong group in the lower left. Made 8 points.
D) Strong group in the upper left. Used for making territory.


You probably are stronger than this guy. You make good solid formations that look like something that one sees in pro games. But then you don't use your strong groups.

no, but the game was already quite different at this point. In case you're interested, here's the game:

Yes, you're right about that. I thought that I should be happy to get 4th line territory.


Right. Actually, I wanted to keep him unsettled so that we both run, but I see what you mean.


Hmm, I was proud of this move. Now I can play C14 in sente to help settle my center group. Is it really that bad ?

I agree this is probably the turning point. What move would you suggest for black instead ?


I have a judgment problem then, I thought this one was weak, until . But yes, It can live locally, so you're right.

Thanks for your comments !
