Typical good 19 hand fishing table.
Effective stacks are 100BB full ring.

I'm dealt 22 in MP3.

2 limpers when it gets to me, I limp. CO calls, SB completes, BB checks.

$0.60 pot, 6 players

Flop is Q52 rainbow.

Checks to me, I bet $0.40.

CO calls, the rest fold.

$1.40 pot, 2 players.

Turn is 8h, bringing 2 hearts to the board.

I bet $1.10. CO calls.

$3.60 pot
River is Q (no heart).

What's the best bet here? Value bet (how much?) or push? The action seems like he has a Q with bad kicker-- maybe he bites on a push. Or do you value bet and hope he 3-bets trip Q so you can get him all in?
