C[This move seems bad, since it allows White to play g8. It would have been better to play g8 or b10 instead.]
;W[g8];B[i7];W[h9];B[i9];W[i10]
C[This is a trick move. Black should answer at j9. See https\://www.hexwiki.net/index.php/Foiling]
(;B[c9];W[b11];B[e5];W[f3];B[d4]
C[Black's d4 already has a virtual connection to the 1-edge. Although it's not connected by an edge template, it is connected by what drking's site calls a cascading edge template and I think of as a ladder-creation template. It will create a second row ladder. Black doesn't have a ladder escape, but Black has a ladder escape fork at h2. https\://www.hexwiki.net/index.php/Ladder_escape_fork]
(;W[d3]
C[This move seems bad to me, because Black responding at c4 maintains Black's connection to the 1-edge. Better options are c3 or d5.]
(;B[e3];W[e6]
C[I likely would've tried something more towards the right.

Since White d3 already serves as an escape for height-2 ladders along the A-edge, White does not need another move near the A-edge.]
;B[d7]
C[Black presumably wants to make it harder for White's d9 to connect through c8.]
;W[f7];B[e7](;W[f5]
C[This move seems bad to me because it allows Black g5. Instead, I would've played somewhere near Black's 11-edge, to connect things together there. I think f8 instead of f5.]
;B[g5]C[I _think_ g5 reconnects to the 1-edge](;W[d6]
C[Instead of d6, I would have played somewhere near Black's 11-edge, for the same reason as before. Again, f8 seems to be the best option. Also, if g5 is indeed connected to the 1-edge, then i4 might be a good option for White.]

C[At this point g10 might have been an option.];W[f11](;B[g10]
C[A losing move, since White now has a forced win available via g11 and then the second row ladder at b10. A better move would have been Black h10. ]
;W[g11];B[h10];W[h11];B[a11];W[b10];B[a10];W[b9];B[a9];W[c7]
C[At this point White is connected by edge template\: https\://www.hexwiki.net/index.php/Edge_template_IV2b. White did not see this.]

C[The correct way to defend the template would have been B5.];B[b5];

C[White manages to recover and is again connected by template IV2b, this time at d3 and c4.]

W[f8]C[A better move.])(;W[i4]
C[Also an option. This gives g8 another way to connect to the k-edge, via a ladder at h7. If Black does not defend the connection from g5, White can potentially cut him off.]

C[This would have been a better move. The point of b10 is it both threatens to go up the left and serves as a ladder escape for a subsequent black piece at g8.]
