Oh, in regard to this... this is one reason I raise this spot... I'm happy to fold to a 3bet, because if he 3bets I know he has a jack, and since I have no idea what his kicker is, I just fold to avoid paying off a boat with a flush. If he calls the raise, I tread carefully. And if he folds, well we just won with ace high. Calling with a non-nut draw is not something I like to do, unless I have a good idea what villain's range is.(but i didnt want to pushed out the hand by a bet/3bet line)
