[Potowame]

in the SB with the UTG player folding , and the Loose agressive player Limping to try and steal with a auto bet on the flop, I would think that I was ahead or I would have been raised by the aggressive player. Plus you should be ahead of a random hand the BB has.
with the blinds being that big I think its a good time to push preflop, and hope to win the pot right there. With 4 players left and the blinds being $250 / $500 it seems that everyone was waiting for the aggressive player to knock someone out then open up thier game. Another reason to step it up and let the weeker players blind out.
The worst thing that you can do in this situation is complete the blind, either fold (which 4 handed is not right) to hope the BB and button get in a war or Raise it, a call is a bad play in this point of the tourny.
