UB 50-100: First Trifecta and I think it was a mistake

[Gamblor]

UB 50-100, I'm slightly underrolled for this game but a brutal LAGgy-maniac has me taking a shot.

Maniac raises/3-bets 75% of his hands preflop and follows through all the way (when checked to). he's already reloaded.

9-handed. I get AJo and open raise UTG, as usual maniac 3-bets and its heads up to the flop. yes i missed an easy cap here.

2 to the flop ($375) J [img]/images/graemlins/spade.gif[/img] 4 [img]/images/graemlins/club.gif[/img] J [img]/images/graemlins/heart.gif[/img]

I check-raise.

2 to the turn ($575) (J [img]/images/graemlins/spade.gif[/img] 4 [img]/images/graemlins/club.gif[/img] J [img]/images/graemlins/heart.gif[/img]) K [img]/images/graemlins/spade.gif[/img]

I check-raise. (Is bet-3-bet a better line?)

2 to the river ($975) (J [img]/images/graemlins/spade.gif[/img] 4 [img]/images/graemlins/club.gif[/img] J [img]/images/graemlins/heart.gif[/img] K [img]/images/graemlins/spade.gif[/img]) 8 [img]/images/graemlins/spade.gif[/img]

I check-raise and he calls.

Now, is this guy gonna stick around and continue to hand away his money or will this wise him up a bit?
