I would probably play a ladder escape instead of connecting, for example c4.]

j2 would have been a simple ladder escape fork, and I'm not sure i3 wins.

Mohex\: i3 does win.

Black i2 and j2 now win for the same reason as 31. j2.

I thought of White h2 as an alternative to h3, but Black wins there, too.]

C[Eric\:

Losing move. i2 now wins for White.

Mohex\: so does g10, i9, or i5.]
