;W[g11]C[Peter\: This was locally a mistake, because it still leaves j6 as a forcing move (threatening i10).

White should have played i7, which, due to the ladder escape fork, would not have left j6 forcing.]

 ;B[h4]C[Peter\: Mohex tried this, and it made it relatively harder for White to pull off the win.

During the game, I thought that the black stones on rank 6 are probably too strong and will allow Black to do some kind of switchback. I am surprised that this wasn't the case.]
