If they have seen you push on a bluff in the past, push.

If they think that you need a monster, value bet 2/3 to full pot.

I am having some real problems putting either one on a hand.... to make that cold call on the flop, I think that limper has to have a set.... but I don't know how he can check turn and river with it.

LAG could have a couple different hands, considering the great odds he was getting on the flop, but I don't know what he can call with since he, too checked both turn and river.

Overall.... I think your image determines your play more than anything else.... but given the likelyhood of a set from MP... I lean towards a push.
