re: Poker & Dilemma - 3.30$ buy in - 60 max
It's opponent-dependent, but I prefer betting the flop to checking. Sure, either opponent might have an A. But from their perspectives, whether they have one or not, so can you. And since you're the original raiser, they're likely to think that if you do have one, you also have a decent kicker. Also, the fact that both just called pre- reduces the probability that they have a big A because if either did, he might have found a 4bet.
In addition, what if you still have the best hand? Betting seems pretty likely to win the pot whereas checking makes it quite easy for the BB to win it by betting with anything.
