Hero - TAG 25 y/o brown guy, $550

V1 - MAWG, seems fairly conservative, and a thinker. $300

V2 - Spewy MABG, bluffed AI 689r10 board when H fired both streets in position. Hero called with J10, V showed KJo. $450

OTTH:

Hero CO: 10h10d
Folds to V2 in MP who limps, Folds to Hero who makes it 15, V1 in BB calls, folds to V2 who calls

Flop ($46)
2s 10c 2d

All check

Is there any merit to betting this flop to balance our range? I frequently fire cbets (maybe as high as 75%), but in this scenario I didn't want anyone to go away.

Turn ($46)
6s

V1 leads for 35, V2 flats, Hero thinks a little bit and then calls.

Turn brings BDFD potential. I figured at least one of them now has the flush draw. Again, is there any merit to raising this turn for value? If V2 was on a flush draw, he'd surely call regardless of the odds. This seemed like a chance to build the pot. V1 had previously shown the ability to bluff missed draws, so I figured if the turn bricked, he may fire.

River ($151)
Ks

V1 leads for 125, V2 thinks a little bit and then calls. Hero thinks a little bit and then jams.

Spoiler:

Our SPR against the spewy guy is ~7.5, so we can play for stacks (our goal) with three ~3/4 PSBs.

It's obviously a pretty drawless board, and we have it crushed (apart from someone having 2x), so I guess I don't hate checking behind. Hopefully someone will catch up to a piece or try to buy the pot. And with us in position, we should still be able to play for stacks eventually by the river by raising all-in.

However, I would probably lean towards getting the ball rolling by betting a small cbet on the flop, no more than $20. The spewy guy might play back, pairs/overcards might peel anyways, etc.

On the turn if we flat the pot will be $150 with $300 back for the donker, which is asking a lot to get in on the river. I'd probably lean towards a small raise that is enticing for draws to chase. If we went just $50 more to like a minraisish-looking $85, that would setup a PSB shove for the river. Again, I don't completely hate flatting as this'll probably entice the bluffer to do his thing again on the river, but we miss value from hands that possibly consider continuing here.

River is easy jam as played; it's only $175 more on top of the original $125 bet, it's almost a minraise.

Apologies, I had actually gotten the starting stack sizes wrong. I've edited my original post.

My raise was effectively $275 on the river on top of the original $125 bet.

Now knowing the bigger SPR of 9.5, I would more lean towards betting at least something on the flop, and definitely raising the turn.

The river jam is still standard, I would always do this with a nuttish hand almost regardless of how lol big it is (and it really isn't that big of a raise in this case, only just barely a 2x raise).

Normally I would say bet something on the flop but you have this board so crushed I think checking is better. Let the spewy guy have a chance to bluff at this is often your best chance to make any money. I would still throw in a $20 bet sometimes, both for balance and because villains are unlikely to give up any pair on the flop.

When there is a bet and call on the turn you should raise something. If you call here and the flush doesn't come in on the river you will often miss any chance to get a call when it's multiway. Make it look like you have JT/99 or even represent a flush draw yourself. Smallish works in your favor, I would go $80.

River is obvious given the action. It's very rare you will get both to call no matter how you size it.

If you're cbetting 75% of flops, then you're cbetting this flop with AK/AQ, etc. So you have to bet the top of your range here.

And it's a fantastic board to bet. No PP will fold. A2s sure as hell won't fold. No one is ever going to believe you hit this flop. Easy bet.

If I bet this flop, I'm betting $15. I have a lot of third pot bets in my range, so that's what I'll do here... AP on flop, everything looks fine. I think checking back flop then raising this turn would look crazy strong, so yeah I'm flatting turn. River shove is obvious.

Flop flat is fine imo.
Raise the turn.
Bet the river more in absolute and relative terms.

What do you mean by "bet the river more in absolute and relative terms"?

I misread your post and thought you bet $125 on the river.
If you jammed then you can't bet bet more, so nbd on that street.
