Hero???

My thought process is I very likely have the best hand against their ranges. I put BB shortstacker on str8 and BTN on low flush. If I know BTN steals like 40-50%, then his high Axdd and Qxdd almost all of them raises preflop. Therefore, since he limped, my read was he had a weak starting hand.

The problem is, I'm not too sure on live player stack off range on 3flush boards when obvious draw hits. If or since I had 4bet on this turn to $500, is this overplay?

TLDR-- BTN capped at baby flush, correct play to 4bet turn with my medium flush and risk running into nut flush?
Also is there a 5/5 or 5/10 forum?

In live poker this is just about the easiest fold ever, btn is never bluffing and never has a worse value hand

he is never bluffing (agree).

easiest fold? (questionable).

He's never raising broadway with Q here for isolation with the short stack? This is always a better flush? There's 13 combos of better flushes remaining if he plays all suited Aces and all suited Queens down to Q2s (unlikely) and a few of those can be discounted as he should raise AQs 95% of the time, and Q4s-Q2s should be folding some portion of the time.

There are 15 combos of worse flushes possible. And at least 60% of those should be in his limping range. So we lose to ~10 combos and beat 9 combos of better flushes. +10% spaz out factor. I could never fold here.

I'd flat and bet/fold most rivers for a healthy portion of the pot.

OP just explained that the button almost never has diamonds here.

So we think that he flats our flop bet with top pair+nfd or gs+snfd?

Also, if this guy is raising a lot on his button we really expect him to be passing up on raising suited Aces in position? I dunno, just seems hard to pin him down to only value hands that have us beat.

I think we are making a lot of assumptions with no given reads with the BB left to act behind us but I fold pretty comfortably.

if you put the BB on a straight and the BTN on a lower flush 100% then flat to try to bring the BB in then bet/call the river.

However, OP just gave his opinion on what the BTN/BB might have had without giving any actual reads as to why. But I see loose passive (see the btn limp) players flat with AXdd and QXdd here all the time. They also are never 3betting this flop with a worse range.

Given the info I can only go by SOP live play which is the turn is a clear b/f.

SOP?

standard operating procedure

no.

correct.

no.

...in the games I play...

I guess I didnt explain myself clearly. BTN villian raises a wide range. My read on him is he is unlikely not to steal with Axdd. That leaves Qxdd. I was never thinking about folding any point on the turn. I was thinking about whether to call the 3bet on the turn. Then on the river, I donk into BTN or c/c. Imo im only losing to like Q2dd-Q7dd in this spot from deep stack BTN. The short stacker BB can possibly have nuts but come on, he is going shove with a much worse than flush here with only $80 left so my concern was entirely on BTN. One more thing is BTN probably wnats to protect his low flush from a 4th diamond on the river which is a reasoning for his 3bet. Not necessarily only nuts/2nd nuts.

Yeah if he can thin value bet otr I like a call and chr given the current information or bet/call but it's a function of what gets the most money out of the bb imo

BB is all in, isn't he?..
