Grunch:

pf is fine, I usually try to limp with 77 & smaller as they are not worth much UI.

flop - I actually like your call here. Since the bettor is 2nd of 5 players AND to your right, calling is a great way of seeing how many limpers you have. NOTE: only on a relatively uncoordinated flop like this one!!

Turn - easy raise here. You actually made more here than calling.

Riv - autobet. You lost 1-3 BBs easy. The 8 only helps a VERY unlikely 67.
