1/2nl 9-handed table. I just move to this table knowing that there's a hyper aggressive maniac type player there.I have a monster stack of $1.3k covering everyone including this crazy villian who has about $800 and seems very bluffy happy when shown weakness and raises 80% hands preflop with non-stop action.I watch this guy overplay weak TP but ppl pay him off with even worse pair.This maniac wont hesitate to run huge bluffs and spew chips as fast as he can in many easy spots. Villian raises to $20 from up front,MP short stacker($50) calls,hero raises to $60 with Ac Qd,everyone folds to villian who of course calls,MP calls all-in.we are 3 way with shorty all-in.
Flop（180): Ks Qc Jh villian bets $50,hero calls.
Turn($280): 6h villian bets $75, hero calls.
River($430): 9c villian bets $175, hero?
I plan to call down on most rivers but 9 is really gross though. He could bet with any TP,two pairs or straight on this board or just run some pure bluffs.

what is your hand?

AQ

I probably fold. If he plays as described he might not have a straight and still be value betting. Just fold and find a better spot on this guy.

If V is a true honest to god maniac who has a VPIP north of 50 and has been running triple barrel bluffs or blasting away each street with his entire range greater than 50% of the time then this is a call.

The important thing in playing maniacs like this is to try to generate a read or profile.

Even though they are super aggro, they will still give off reads, tells, and sizing tells. You really want to focus super freaking hard on every hand he is in, his mannerisms, and most importantly his betting and sizing tells.

I'm not saying you figure out his Oreo Cookie tell, but I guarantee you that if you are paying attention to his bets and his chip placement, and his mannerisms you will have more confidence in "feeling" when he is full of crap and when your middle pair or better is good enough to play for $1k stacks.

All in all, though, the way you own a maniac is to just call them down whenever you have a value hand NO MATTER HOW SCARY THE BOARD GETS!!!!

This is why maniacs are so successful against most rec fish. Rec fish just tighten up waiting for that big overpair or trips or the nuts to finally "get" that maniac. Unfortunately, those hands happen less than 3% of the time. You can literally wait 1 or 2 hours before you get that "big hand" against the maniac, and in the mean time, he is spewing chips everywhere. By the time you get that "big hand" odds are all his maniac money will be gone.

And the truth is, you don't need that big hand to "get" the maniac. His range is so wide, and he is so aggro that pretty much ANY value hand is good against a maniac. So the way you own maniacs is to station them with all your value hands...

So in this case, we call and feel okay about it. Of course, its not a fist-pump-kung-fu-kick call by any stretch. But against a maniac I call here.

That river 9 really complicates matters further because calling the flop + turn got you no additional info. I'd take note of his bet sizing, but it could be nothing as its live. As played, I'd fold, but you seem to think a bluff here is really credible. You could have paid him off here and got it back later. Interested to hear the results, what the short stack held.

I think a key decision point is the river sizing.

His flop and turn sizing appear to be for pot-control, setting his price. The additional $100 otr may be for value, the reason any recall on previous semi-bluffs would be helpful. Sans that info, I'd lean toward a fold.
