C[This is a questionable move. Black d4 is connected to the 1-edge via edge template A-4 (http\://www.mseymour.ca/hex_book/hexstrat9.html), but it is too far from black's main group to be a real threat. White is free to respond elsewhere. A more forceful move would have been h3, which would be a forced win for black.]
;W[g4];B[e6]
C[Black's e6 is connected to the 11-edge via double threat, but it is still not connected to d4. White could separate them at d5 or e5, but chooses to invade the edge template instead.]
;W[c3];B[b4]
C[Black recognizes that c3 provides white with a ladder escape along the A-edge, and attempts to ward this off with an attempted min-maxing move. The trouble is that it doesn't really keep d4 connected. White is free to take the initiative and respond elsewhere.]
;W[c6]
C[This move immediately threatens to connect to white's group via e5. It also reconnects c3 to the A-edge (by escaping the 3rd row ladder at c4) and is therefore an excellent minmaxing move.]
;B[g3]
C[In an effort to defend against both connections from c3 and c6 simultaneously, black plays g3.]

C[It's not obvious how white can win the resulting 3rd row ladder. ];
B[j3];W[i4];B[j4];W[i5];B[j5];W[g10]
C[! An unexpected move. Black can now redirect the ladder away from the K-edge, but it may not be enough to keep white from connecting.]
(;B[i7]
C[Black wants to move the ladder further from the edge, while not permitting white to outrun him. Although this is ultimately unsuccessful, Mohex actually computes that this is a winning position for black.]
;W[h7];B[i9];W[j9]
C[A reasonable template intrusion, guaranteeing that any white piece at i3 will connect to the K-edge. A bridge intrusion at j6 would have not been desirable, as it would require white to play h6 and give the initiative to black.]
;B[h10];W[i6];B[j6];W[i8]C[A sequence of forced moves ensues.];B[h8];
W[h9];B[g8];W[f8](;B[g7]
C[This is black's fatal mistake. According to the Mohex solver, f10 would have been a winning move for black.]
;W[e8]
C[Now black is disconnected and white has an easy way to the A-edge.](;
B[b8]
C[Not a good move. White could immediately bridge to c6 via d7 and complete the connection.]

B[resign])(;B[a8]C[This move would not save black. ](;W[b7]
C[White is connected. c6 and b7 are connected to the A-edge by template E-3. In the next move, white can neither play e7 or c9, and black cannot prevent both. b7 serves as a ladder escape for c9.]

C[According to Mohex, both e8 and e10 would be losing moves for black. Black must first attack the bridge at f5.]

C[And now, finally, is a good time for black to disconnect white's biggest group, according to Mohex.]

C[Apart from filling in bridges (which does not help white here), black's moves are forcing. To see the sequence without the filled-in bridges, see the next variation.]
