Oceans-11 20/40 full ring.

Villain-1 is bad, but not super fishy bad. Loves to slow play, cold-calls too much preflop, but can be pretty nitty post-flop, but never folds a hand with showdown value

Villain-2 fairly nitty preflop, but has some sense about limit holdem and knows when to step on the gas and when to slow down.

I raise KhKd UTG. I announced a few minutes ago that I was getting ready to leave, but I don't know if Villain-1 heard me, or if he is even paying attention, or cares about things like that.

Villain-1 cold-calls, MP calls, button calls, Villain-2 in the BB calls. 5-way action to a flop of:

8h 5s 2h

I bet, Villain-1 raises, folds to Villain-2 who calls. I 3-bet, all call.

Turn is Th.

Checked to me, and my plan for the rest of this hand is?

Bet, suck out if raised.

Play in tempo, bet turn, see how EP villian and MP villian react. Checking the turn feels like a mistake, unless you are planning to c/r and fire most rivers. I would just hate to see both passive villians check behind.

Yeah, what the others are saying. Bet/call turn. If unraised on turn, bet/evaluate any river.
