$2/$4 Deep Stacked With Big Draw

[XChamp]

BB is 45/22 over the 90 hands I've played with him. He has checkraised my cont bets 2-3 times and I've folded each time.

I think my reraise to $180 is fine. The problem is that after BB re-reraises I think he most likely has a monster. I think there is a 5-10% chance he has something like 45o or a horribly played AA (I've run into this a lot lately at NL$400 against donkies).

What do you do?

I would just have called his reraise and taken another card. $1/2,$2/4 NL they dont seem to just give up on boards like this on a 3 bet.

My plan would be to call a pot sized bet from him on the turn if you miss the board or raise a large amount if you get there.

If the board pairs this could get ugly.

Normally I do exactly what you wrote, but due to his history I felt his checkraise could be almost anything. I only like calling his checkraise if I think he has a strong hand (2 pair or better). I did not think he had a hand like that.

Obviously once he re-reraised I realized I was probably incorrect. But, so much money is in the pot now. Should I get away from the hand or am I committed?

After you 3-bet and he 4-bets I'd just get it in now, you really aren't in terrible shape against anything except the rare combo draws bigger than you.
