Although I do not agree with Paul's call with the 45s he said he thought the other guy was on a resteal and thus he realized he would only be a 10% underdog, even against AK! (obviously a resteal would not be attempted with a serious pair) And this may be an accurate assessment, you never know. Maybe Haveson had been stealing all day or had been protecting his blind and Paul picked up on it. Paul was, no doubt about it, on a rush as well so maybe that was just a cover up for him to play a pot with a deceptive hand with the momentum and a chance to make a lot of chips if he flopped a hand. If he still stuck with the idea his opponent was restealing it's possible maybe his opponent is on a draw as well right (not flush of course or the call would have been pathetic), so when Paul makes a flush draw he says what the heck and calls since he is already invested. NOTE: I do not like the call, I said that, but I believe these are a couple of reasons Paul MIGHT call--I've seen worse plays.
