I'll give it a shot:

Hand 1 I'd probably raise the flop or turn, but either way, I'd probably get it in. Looks like a cooler though, what'd he show up with? AA/KK?

Hand 2 fold or shove turn imo. Pretty sure if I call the turn, it'd be b/c I thought I was good & therefore I'd be calling the river.

Hand 3 calling the turn is ok. Folding the river seems bad, I know I'd at least call.
