Well I'm not saying it's impossible that you will be raised by a jack or pocket pair here, but I just really can't remember it ever happening to me in a similar spot. As for the comment about the flush draw, I think if he's aggressive he seriously bets or checkraises about 90-95% of the time. What do you think that number is?

I don't think reraising is "out of the question" at all. But I think if your 3bet is called or reraised, you're winning here (not including splitting which we can ignore) somewhere between 50-60% of the time. Thats just a guess though...I really don't know.
