1/2 game

My stack is around $450, just changed tables because I noticed maniac (now two seats to my left) at new game sitting with $800 or so and spewing chips. He has been playing every hand, frequently raising air preflop, raising blind, betting with air, etc. I've only been at the table for a few hands and the table shouldn't have any reads on me other than I'm a white male in early 30s with a rather unkempt beard and glasses.

V1 is said maniac with~$800
V2 is new to table, bald 40ish blue collar guy with ~$300
V3 has been at table, haven't noticed him doing anything yet, late 30s white collar guy with ~$400
V4 seems to like to chase draws, has ~$300

UTG (late 30s woman) limps, I overlimp with AQ, player to my left limps, V1 raises to 8, V2 3-bets to 16, V3 calls in hijack, CO, Button and small blind fold, V4 calls in big blind, UTG folds, I call, V1 calls.

Pot: $93

Flop AT7

V4 donks $10, I call, V1 and V2 fold, V3 calls

Pot: $123

Turn: 4

V4 bets $15, I raise to $50, V3 calls, V4 folds

Pot: $223

River T

I check, V3 bets $150, ...

Dynamic is out of whack, and the new guy is more than likely unaware of V1. V3 on the other hand should have an idea of how V1 has been playing, and he's probably staying out of hands while waiting for a "monster", typical response in LLSNL games when there's a maniac at the table.

I definitely wouldn't 4-bet pre, especially doing so would push off the very target that made me move to this table.

AQ is not strong enough to slowplay OOP 5-handed, so what was your plan to flat that silly donk bet?

I also don't like the size of raise on turn, I would make it much closer to $100.

River is difficult because of bet sizing in previous streets.

Is villain making a play with a busted flush draw, especially seeing how weak we had played previous streets and then checked the river?

Is villain value betting thinly with Ax, but why would he just call flop or turn and then bet so strongly with that same hand?

Was villain floating with Tx flop and called the turn because the weakish turn raise, and now he's value betting?

Is he slowplaying AT, TT or 77? But unless he's a habitual slowplaying donk, those hands would have easily raised the turn, if not flop. Most people in these stakes also have MUBS and would have raised to protect against flush draw.

V4's flop donkbet needs to get raised. I like something ~$60-65, which would set up a $200 pot on the turn. If he really does like to chase draws, why not charge him the max?

Without a read on V3, I'm inclined to let the river go, though the more I think about it the more I'm thinking call. Sizing tells us he wants a call from a strong made hand, although you did make it super cheap to draw if he did have one.

Questions about V3:

-How long have you been at this table?
-How many flops has V3 seen while you've been at the table?
-What range did you give V3 when he cold called the small 3bet?

On flop I was a bit too tentative with the preflop 3-bettor and cold caller still to act. But I think making a decent raise would have been a better play.

I agree turn sizing is bad.

I've been at table less than an orbit.

Not how many hands V3 has played at this point, but he has not yet been the preflop aggressor.

With basically no read to go on, I'd guess his preflop range consists mainly of TT, JJ, QQ, AK, and big suited aces, sometimes could be oddly played KK or AA, and if villain is looser or playing for implied odds with maniac, his range could include any pair, suited broadways, maybe suited connectors

That is the strangest betting action. Pre-flop I would open the betting instead of limping, but limping is cool once in a while. I think the pre-flop could get more analysis but I'll move on. 3-bet pot, with 5 callers.

Flop: $93, and the first to act donks $10? what is that? Right here I would say you made your largest mistake by just calling. Re-raise to $60.
As played: then the original opener and 3-bettor pre-flop fold to the $10 donk?
What in the world is going on at this table?

Turn: Again, you have got to put in a large re-raise here, I think $50 is not enough. But, V3 made the call. So he's got something. Spade draws are certainly a big part of his range, including the ones that already have a pair, AsXs and TsXs varieties.

River: Bet the river here yourself, since you are probably going to call if he bets a reasonable amount. As played, I think you have to make the call.

Opening with maniac to your left is not the most optimal.

You have no information on V3 and he had odds to make a call with something like T9s, K10 etc. That river 10 would have scared me away. A substantial reraise on the flop, around $35 would have given you the info you needed about V3 (sort of) while also getting more value out of the donk at the table. If V3 was still in on the dead turn card, I'd have checked. River? Check/call. This is a hard hand with no info on V3 you you need to give him respect. Also, not that it would be helping much, but if you have no behavioral info on someone and your 50/50 on something, make like Navarro/Caro and look into non-verbal and visual cues like the way they have their stacks, their dress, whether they're drinking or not (even energy drinks as they increase impulsivity). If I'm 50/50 on something these tells might hinge me one way or another, but again it's not something you should take too seriously (coming from an almost Doctor in Psych haha)

I'm sure the experts here have way better math odds to help you with but regardless you should read a little on Joe Navarro for times when you have absolutely no table-behavior-info.

Please explain the meaning of making such small raise on flop.

Poor reason to bet. We want to bet for value (get called by worse) or as a bluff (not recommended here).

The hand was played so strangely that it's hard to know if we can get value. Not sure if we can get called by worse.

The $10 bet comes off to me like "may I see another card for insanely cheap please?" to which, for some reason you replied "Yes, yes you may." Agree with all to pop it up here. How many turns are you really going to love?

4 of clubs, there is one. But then you min-raise so tiny...

Then on the end, I think I'm throwing out a blocker bet. We have no idea where we are at in the hand, but after raising the turn and leading river, we take the play he made away from him.

Really tricky hand, but agree with you that you didn't play it well on any street.
