C[A weak move.

g6 would have been immediately winning for White, since it would have connected White to the K-edge by https\://www.mathstat.dal.ca/~selinger/downloads/hex/template-Z5.png]

C[This looks like a wasted move, since it doesn't threaten Black's connection to the 11-edge via f9 or h9.]
;B[f5]
C[This is also a wasted move, since g5 was already securely connected to the 1-edge.

g7 would have been immediately winning.]
;W[e10];B[g7]
C[f8 would have been more immidately winning, as it connects Black's groups while also maintaining the connection to the 11-edge.]
