W[d1]C[Bad move because it permits c3.];B[d2]
C[Weak move. c3 would have connected to the edge immediately by template B-3.]
;W[e1];B[f3]
C[Good. This move threatens 3 things\: a ladder escape for d2, a connection at e4, and if foiled at f2, a connection at f4 via template E-4. 

g2 would have also worked as a ladder escape fork, and would have been easier.

Black is now connected to the 1-edge.]

C[There's a ladder escape fork at b10 via c8 that would help this stone connect to the 11-edge and be an easy win for Black.]
;W[f9];B[c8]C[b10 would have been better.];W[c9];B[a10]
C[b10 would still have been better. The problem with a10 is that it does not escape a 2nd row ladder along the 11-edge...]

C[b5 would have been better as it would have cut off Black.];B[a6];W[b5]

C[This is an unnecessary move that White can ignore.

It would have been better to play d10 and then Tom's move h9.]
;W[g10]C[This move creates a non-template and invites f10.];B[h9];W[h10]
;B[j9];W[i8];B[i9];W[g9]C[This move reconnects White to the A-edge.];

C[This move isn't forcing, so White now gains the initiative. ];W[g4]
C[Probably White intends Black to play i4; White would play i3 and be connected to the K-edge via ladder escape.

However, Black now has the forcing move g5 available which would require White g5, and then Black h4 would be winning.]
;B[i4]C[Black falls for White's trap.];W[i3]C[The game is decided.];
