Given that MP2 was a poster, and the button essentially open limped, I really like a raise here. Your opponents probably have very bad hands.

The turn is an interesting situation. If you bet, almost all hands aside from sets and straights are going to fold. By checking you may fill on the river, you may induce worse hands to call a river bet... This is an interesting spot, I would probably check, but looking to call down an aggressive player.
