Without any specific reads I dont think that this should be a fold. Against a very tight player that never x/r any draws you could find a fold but against an unkown I think you should gii here. I think it shouldn be too hard to come up with his x/r range here.

I hope i did this right with pro pooker tools cuz i normally use a different program. So if we only give him made hands, which means any AAxx combo (very unlikely cuz he would 3bet from the BTN a lot),77xx and A7xx we have 45%!!!!

If we ad some big draws (89TJ. 5789) we still have around 46% but if you can take out a lot of AA combos because ppl would 3 bet with them IP than your equity goes up to 55%. Even though I gave him a pretty tight x/r range i do think you can gii here with some backdoor potential as well.

Oh sorry, didnt see that! Its kind of confusion reading hands with this format.

In that case i think you are better of folding. You will be up against a bigger set vs2 ppl quite a lot of the time and if not one of the two will have a wrap so you are never gii as a big favorite even though it looks ugly folding flop might be best imo.

Quick multiway sim (using PokerJuice range macros in Odds Oracle):

BTN flats $FI25 ! $3B6I
BB flats $FI25 ! $3B6O

There are some bad AA in both flatting ranges. We look at the tight, simple case where fold equity is zero and they both are raising sets and (mostly) nutty wraps with 13+ outs:

BTN: ($PJFI25 ! $pj3b6i) : (AA,77,66,T98,985)
CO: ($PJFI25 ! $pj3b6o) : (AA,77,66,T98,985)

We have 20.3% equity here. So you need some combination of fold equity and looser ranges to get it in good. It looks like a tall order. You c-bet 3-way with plenty of AA in your range, and they don't care.

I think its super easy cheap and explo fold meaning if somehow BN overplayed top2+ hand e.g. A785, then BB most likely HAS it by having set+ e.g. AA45 or super-20cards-non-nut-wrap 9854 with potential bdfds (though u have 1).

Vs BN/BB having A7/9854 odds for Hero are ~ 21: 25/54 and

Vs BN/BB having A785/9875 odds for Hero are ~ 31: 29/40.

U need to put 43$ extra to potentially (presuming BN stacks off also) win 150$ which is ~29% which you have in best-case-scenario and that is 2nd case. Range of BB is super strong here....

Nb We even did not take into account that someone has AA or 77 - hands that dominate our bottom set almost without bd draws (we do have Khi bdfd and chance to hit King if somehow we dont play vs AA but vs 77). Vs BN/BB having T987/AA odds for Hero are  ~ 7,5: 44/48 which is very interesting not getting into it how realistic it is for opponents to have those hands.

Follow-up: 

Interesting to note the effect of different preflop ranges. If we switch from PJ ranges to PPT x% ranges the result changes significantly:

BTN flats 25%6h ! 6%6h
BB flats 25%6h ! 6%6h

And we stack off against: 

BTN: 25%6h ! 6%6h) : (AA,77,66,T98,985)
CO: (25%6h ! 6%6h) : (AA,77,66,T98,985)

Now we have 33.3% equity and it all looks good. But is it? I doubt it.

All bad AA being removed from the flatting ranges by "!6%6h" explains a lot. In reality, people flat their worst AA. As they should, especially OOP.

Spoiler alert.... (as if this wasn't obvious by the post)

I fold and the button shows, A79T and the bb has 89T7.

Turn was a 6.

I was really expecting to see 77 or AA here, so this surprised me. Especially since this board is rainbow. I am glad that the RIO consensus is the same as mine though. Thanks guys.

I agree on the the fold. Wp UL Trondeez.

But would this ever be a call if both players had a very high VPIP, flop aggression

factor and raise CB% ? like 50% VPIP for both villians, button raise cb30% or

more over decent sample. Or is 77 now a more likely so its still a fold?
