Frank\: It looks like this mistake causes White the game? 

Mohex\: Black was winning anyway. If White plays i4, Black e5 still wins.]

Good, since this kills h4.]
 ;W[g6]C[Eric\:

White should probably have tried H2 now, before Black's D8 chain gets closer to the 1-edge.]

It's unlikely to matter, but White should get this, to make sure Black can't have a forcing move at J7.]
