Here is an interesting hypothetical situation.

You have been playing at a table full of rocks not making much money when an overly LAG player arrives. Within a few orbits, the LAG player puts on a few bad beats to the rocks and now everyone at the table has loosened up. The table has turned very profitable for you. Several times you have been able to re-raise after the LAG player raised and several of cold calls followed ,and take down good sized pots uncontested. You also generally benefitted from the looser play a couple times when players have overplayed top pair good kicker.

Pretty soon you find yourself in a spot to call the LAG player all in for what is a moderate +EV situation (let's say two over cards with a flush draw up against what seems like top pair). You know that if you bust this player he won't be buying back in and if he leaves, the rocks will settle down and stop spewing money.

Would anybody fold this +EV hand because the +EV of the table dynamic that his presence creates?
