How can OMFG cap flop raise turn and raise river with this hand, is this STANDARD? or is this just spewing....seems like it would be spewing against most opponents....and what is PerpCzech calling with...AQ, 55, 44, and 33.....or is this just a case of the bet fold play but he couldn't bring himself to lay down the hand.....I don't understand this hand at all so if any of you high stakes LHE players could explain this to me that would be great!!!
