USGO1 [-\]: welcome to the 4th round of the cotsen open here in LA
USGO1 [-\]: this is chris garlock, recording
gogeo [8k\]: when will be 3-3 invasion? before 20 movies?
rainman [9k\]: yes
USGO1 [-\]: this game will likely determine the 2017 champion, as both players are 3-0
gogeo [8k\]: Hi Chris - thanks for you work on go ! 
medical [4k?\]: big game, big kibitz :)
USGO1 [-\]: lee has won easily the last two years; surma is here because he was in mexico for the go congress
Tako [?\]: so mateusz won to Andrew Lu yesterday ? the game looks unfinished on KGS

C[Uberdude [?\]: i seem to recall there is some magic tsumego in b's shape here in some variations
mooooo [3k\]: f1 propably too small until midgame
cekalo [1d\]: why w e7?
Uberdude [?\]: to capture black =)
mooooo [3k\]: i guess strong outside group more important then life small
cekalo [1d\]: why
Uberdude [?\]: otherwise black can escape and w is cut
USGO1 [-\]: surma fingers stone, hesitates, retuns it to bowl
Uberdude [?\]: (perhaps not immediately depending what move you suggest instead, but will likely have to come back)

psibrr [4k\]: isn't f1 25 pts + defend  o4 with attack on J4 group

C[this is a mistake; white needs to help the lone stone on the right, maybe A is best]
LB[pm:A];B[pm]
C[after black 69, black has about 50 points and white and 25-30 at most, with not much in the way of prospects for more. plus two weak groups, one on the right and one below middle]
(;W[qg]
C[RainierBob [?\]: Surma was in Mexico earlier this month a a visiting pro for the 1st Latino-Americano Congreso de Go.

This is an overplay but white doesn't have a lot of good options here (see var); black is so strong and is ahead on points, so doesn't even need to kill, just make terr while attacking. ]

white is still in trouble; the lower group owes a move and if the center-right group gets sealed in, it just has one eye]

C[Mateusz' attack was a bit stronger than I expected; I met him 4 years ago when we studied at the same school and he's improved a lot since then. But the problem is that the white group on the left can only make one eye and black has sente moves around the marked stone, so it shouldn't be a problem to get a second eye.]
