1. fold. we beat nothing.

2. fold. doesn't look like he's ever bluffing after checking that turn. you look pretty showdown bound.

3. 4bet preflop. postflop looks ok. i'd probably bet like 1/4 pot on the flop sometimes.

4. preflop is ewwwwwww. AKo OOP in what's probably going to be a multiway pot is just asking for a backfired situation. this isn't a spot where i'd 3bet x% and call y% unless y = 0.

i wouldn't try to block-bet-induce-raises from a not very good semi-passive opponent. again that's just asking for things to backfire. this hand as a whole seems pretty bad.

just pound that turn and get money in the pot.

as played river is prooooooobably a fold but it's close i guess. it comes down to if you think he'd valuebet KQ or KJ often enough.
