Really?
With him reraising preflop, of course i was afraid of AA / KK / AK before the flop...but who is gonna bet pot when the flop hits them perfectly?
...Sorry im probably giving away the results, but let me rephrase the question. If we put our opponent on a PP, QQ or lower, is the flat call on the flop the best play?
Alright, if you decided your opponent does not have an A or K, or think that you could get him off a weak A (unlikely as how the preflop action went) then is is going to be a much better idea for you to reraise on the flop.
That is, a bet here looks just as scary as it does on the turn. And your still gonna need to put in $12-15 either way. The difference is if your opponent again bets the turn then it is going to be ALOT more expensive for you to take this away. If he checks/folds the turn, you woulda got the same result on the flop, but you gave him a free card to make his flush. I suppose it would be easier to figure out where he is by his action on the turn, but a pot size bet seems like an awfully lot to float. Plus he can easily check/call you on the turn with Ax. I also definitely hate calling all the way down with out a sick read.
