Fold Flopped Nuts On River against Aggressive Opponent?

[Rob76803]

This hand occurred with about 250 people remaining in FTOPS Event 8 ($216 Limit Omaha H/L). I don't know if this is the right place to post this, but I'm gonna give it a go anyway. Villain is probably the most aggressive player at the table (to a fault) and will also call or raise a single raise out of the big blind every time. I have an aggressive image, as I have been raising a lot from LP.

Keep in mind that this is a tournament, not a ring game. Is this raise OK? Everybody's fairly short here, and the action has been necessarily very aggressive. I raised hoping to isolate with one or two players. I think villain calls here with any four cards. I think this was just about the best possible outcome for me preflop. I get to play against one player with a hand that gets better the fewer opponents are in the pot.

[b]I flop the nuts and get bet into. What's his range here? Like I mentioned before, he's very aggressive. I think he could bet here with any sort of open ended/wrap around straight draw, any flush draw, any two pair, any set or he could be betting that I have all low cards in the hole. I raise, and he immediately reraises. Now I think his range is a whole lot smaller. Two pair or a set is now much more likely, as is something like a straight and flush draw. I reraise to cap and he calls.

Is there a worse possible turn card? He bets and I call hoping to fill up on the river.

Pot=13,200

I miss my boat and the straight comes out on the river to boot. Is there any holding of his that I beat here? Could he possibly be going crazy with pocket jacks after I showed weakness on the turn? I've got about 3,000 left if I fold, which is enough, if I get lucky, to rebuild my stack. 1,400 is a different matter. What do you do here?

For a fold to be correct the chances to rebuild the stack with less than 4 big blinds left should be higher than the chances to win the hand. I don't think that's the case. If that's correct a raise would be the right thing to do.
