When he cbets multiway he usually has something, either Tx or overpair so I'd fold flop. We don't really improve that much on turn, we have like 4 sixes that would give us straight but if we do hit it we won't get any value on the river. Same with 2 eights. So even though he only bets halfpot this should still be a pretty easy fold for me.

I can see folding here vs. super tight UTG player betting into two players. That being said, in many other circumstances this hand is slightly too strong to fold in this spot.

I think multi way I just fold the flop as his lead is strong and our hand is almost impossible to play on most run outs.

In a heads up pot I would call the flop and fold the turn.
