redreoicy: First guess is to make a ladder breaker to play r7

USGO1: Sorry about that, table shook a bit as I placed G15
BHydden: if you're the pedantic type, you can click onto the wrong move 40 and then click the trashcan :)

BHydden: final round of USGC, who could have more important plans than this? :D
USGO1: I agree with BHydden:)
BHydden: ;)
USGO1: Mark has used more than half his time, now being at 42 minutes
xed_over: on this one move? :)
hexahedron: maybe white didn't expect this move by black
USGO1: I'm not sure about Zhongfan's time left, but he IS 2/3 of the way through a starbucks
USGO1: I'm now told by our fearless recording leader that Black has an hour and ten minutes left

Falchion: what did it say the % was at move 114?
hexahedron: around 95% for black
Falchion: wow, already that bad
hexahedron: keep in mind not to trust all these percents too much, we've seen in plenty of games at this tournament that it can swing quite a bit
hexahedron: bot is assuming superhuman-level tactics, in a sharp position it's very possible for one mistake to swing it all the way back to even

Falchion: last few moves feel good for B
hexahedron: KG says 97% for B (white lives in the middle, but black got a lot of profit
hexahedron: )
hexahedron: and connects his own group on the left in the process
hexahedron: we'll see what happens though, the tactics are so complicated

Falchion: B would have to mess up pretty badly to throw such an advantage away though
hexahedron: after the last 3 moves KG is thinking the white group in the middle dies now
Falchion: ouch, that's even worse
hexahedron: it's not entirely confident though, territory map shows it as all blackish, but not completely

hexahedron: G3 nice
Falchion: J4 now maybe?
hexahedron: no, J4 makes no eyeshape
hexahedron: all it would do is strengthen black and immediately kill any hope of black messing up
hexahedron: (the only point that J4 could help turn into an eye is H4, but notice how G3 and J3 already make H4 false)
hexahedron: do you see?
hexahedron: right, and that would help black
hexahedron: there's no ko
hexahedron: the only bit that remains not entirely clear to my lowly amateur reading is the L4 cut aji
hexahedron: but maybe I"m also missing some other variations
USGO1: The clock now tells us that Mark has only 10 minutes of main time remaining
