Well, what do you guys think?

-Hero bets/fold?
-Hero bets/calls any raise?
-Hero bets/calls raises by shortstacks but not by Mp2?
-Hero bets pot, potcommits himself against Mp2 and the rest of the table, switches to 10/20 and watch some better players play the game?
-Hero check/folds?
-Hero check/raises?
