ThiGar [4k\]: so e3 was not very good. What was b to play instead?
USGO4 [-\]: who's ahead at this point?
Wagaboo [5k\]: i would say w
Imp20 [3k\]: black has more territory
ppkp: b
Wagaboo [5k\]: because b is weaker than b
ppkp: but 2 weak groups=-20 points
duelas [4k\]: i would say w too

mw2a [1k\]: seems about even but w has better position

USGO4 [-\]: b looks like hs more terr but it's not solid like w's
evanj [3d\]: correct, meatperl
evanj [3d\]: er, metaperl
USGO4 [-\]: in the fight, the right-side w group will get stronger and then can invade the b area on the bottom
