I think Black should've played c8 or h7, rather than this.]

;W[g4]C[Peter\: I felt that merely playing f9 would not connect, so trying to get something in the k1 area first, although it probably wouldn't have worked.]
;B[f9]C[Peter\: This is a bad move. For example, h5 would have been winning for Black, connecting to the 1-edge via i3 or f4, and to the 11-edge by climbing.

Eric\:

One way to think of that, is the {f6,g4,g5,g6,g7,h5} configuration from  https\://hexworld.org/board/#11,g7\:sf6g4 \:

Bridging through is fairly-often a good move in such cases, because the bridge will be captured - https\://www.hexwiki.net/index.php/Captured_cell - and White's 2 stones will be very separated.]
;W[e5]C[Peter\: Now things look better for White, although White is probably still not connected to the k-edge.]

(;B[h3]C[Peter\: Almost definitely losing move. Black should have played i3, so that White will only have a 2nd row escape. See the next variation.]
