1-2 deep: bottom pair turned into a bluff, bet or xb river?

He called a pot size bet and the river does not create a new straight albeit it might create a new 2p. If you have the hand you are trying to represent(the 9) what was V calling you with that could improve to beat it? If he couldn't improve to beat it will V ever decide they are wrong to discount it?

Fold to the 25$ pre.
Flop I probably bet like 25. If we get called, it's really easy to play. BB isn't going to check/raise air much, I guess he can do it with something like JQ, J9 type hands. HJ most likely isn't going for a x/r unless he's nutted. So in reality, even facing a x/r it's super easy fold.

Turn if we betting here, it's probably with small sizings like 25. We are not betting this big with any hand when they've shown nothing but weakness.

Villain's range is some slowplayed sets(77), some 9x(A9s, 9Ts, 99, 98s), some overpairs, some bdfd.
I think most overpairs fold the turn actually unless he's got some sort of read on you.
I don't think sets are folding much to a river bet unless you jam.

I think jamming is ok. So usually we only get owned by those who're trapping with 9x here. Sometimes we also get owned by calling stations who station us with random hands like 1 pair, 2 pairs, sets and so on. Or if they got a read on you believing you're FOS, you get stationed here as well. If we get stationed here any less than a 9, we can make a note, and valuetown them with overbets relentlessly.

We also have some showdown value vs bdfd, so checking is also ok.

Raise pre yourself. As played, the call on the BTN isn't terrible. Fun hand to see a flop w/ in position.

Turn bet is way too big. River maybe bet $125? Really tough w/o reads. Giving up is fine.

I'm ok pre first time. Also ok with raising. Calling the raise is marginal, but will give you a pass given odds and position.

I think I take my free card on the turn and if I do bet it's small.

River. Dont bluff unknowns at low stakes. Also you have some showdown value. Not inconceivable he has something like KQs and your hand is good.

How are you ranging V? That will lead to your best river decision. Here's what I'd be thinking:

PRE - raise from the BB should be a strong range. Even though we're on the BTN, over-calling with 65s is dicey.

FLOP - check into two opponents on T86rb doesn't tell us much, but we might start to discount some hands that are strong yet vulnerable. He could have some SDV like 99 or 77, or just missed with two overs. If he's checking over-pairs, is that because he's scared of the board texture? Can we use that to our advantage?

No great reason for us to bet yet, so I'd check back a lot, and only bet if I think our opponents are likely to over-fold to continued aggression on later streets. I'd use small sizing, 1/3 pot or less.

TURN - 9x is now a straight, and 77 is a set, but otherwise the 7 doesn't change much unless he picked up the BDFD. I'd think his 2P+ would want to start betting, so when he checks, I think he could have picked up the FD. Occasionally he's trapping with a monster but most low stakes opponents aren't going to check twice in spots like this.

Since the 7 does bring in some additional straights, and our opponents have capped themselves, we can start a bluff. Anything from $60 to $80 should leave us a roughly 2x PSB for the river.

RIVER - the J shouldn't change anything unless he has JXss and ran into top pair, or JJ that made top set, but that seems unlikely, the way he's played this.

When V checks, sometimes we'll have the best hand and can win if we just check back. But we can also probably fold out a lot of his better 1P hands by just sticking it all in. Doubtful he gets here with such a strong hand that he's going to want to play for all the money.

Why did we overlimp preflop? HJ open limp is a weak play from a weak player. I would iso our hand. As played, I am fine to call the $25 in position -- it's basically a "juicer" bet from a player that is also likely a fish.

I think the turn sizing isn't great. What hand are you repping that checks back flop and then pots turn on a four-liner? 77 exclusively? Does 76s even bet this size? Why would we pot it with a straight?

You have a shred of sdv on the river versus two big spades. Your hand also looks pretty FOS. I would probably check back. If you bet, it has to be to a size that genuinely puts him in a tough spot -- it's pretty hard to fold an overpair when you check it twice and the bdfd misses.

You have the button, you have a limper, and you have a straddle - why you're not raising pre is beyond me. As played I would bet the flop - maybe BB has two overs, you already have a pair, make a bet. On the turn you have a perfect bluff spot which you bet and he calls - the river you need to continue with a big bet. Think you need to play much more aggressively in spots where people are weak.
