Hand 1: iso to .50 preflop, then bet 1.50 into 1.60 so that you can shove the turn for like 2/3 PSB. as played, bet flop at least $1. as played, i like it.

Hand 2: iso to .50-.60 PF. as played, i'm ok with either blocking bet/folding river or c/eval (folding to almost any show of strength). i like c/f the most.

Hand 3: spoon's got this one covered.
