Losing move.

White kept White's win for the rest of the game.

i2,j2,j1 were all winning, since i3 has a crescent to f4.]

C[Eric\:

I can prove that this wins for Black, since White's peep at i6 can't work until White has played j6, but that will only happen after Black has k6+k7 connected to the 11-edge, at which point Black will no longer need to keep i7 connected.

Based on how the rest of the game went, it seems like G9 should still win, but it is at least locally bad, since White's response gives White this whole corner.]
