C[Eric\: Better\: c8. Then other than via B10, which would give Black a ladder escape and thus let Black win in the way Black actually did, I don't think White can connect to the A-edge.]

C[Eric\:

Starting from now, Black can win in the way Black eventually almost did (30.h8 instead of 30.h9).

White could have prevented this by first playing the peep at C10.

If White had done this, then at least 30.h8 instead of 30.h9 would not have obviously worked, and I think I'd slightly prefer White.]
