hand 1: pre is preety meh, c/f turn, if you are going to continue c/cing>>>jamming.

hand 2: flop float is fine imo, turn lead I don't mind though I'd make it a size he's more likely to jam over like $145, as played if you think he has no overpairs in his range bar 99 river is a c/c.

hand 3: I bet flop, hate taking c/c lines with the middle parts of my value range, as played fold.
