no brainer?

If you call you need 33%, if you shove you need like 44%.
Vs a straight with a FD you only have like 31%
Vs a set you only have like 32%
So I think its pretty close. If you call you can play turns+rivers accordingly. If the board pairs and he xb you could think about bluffing the river for example.
I think x/shoving here is slightly -EV.

i think its never a set here. Most likley its a str8 or a combodraw like str8&flushdraw

so yeah its close

Def not no brainer. No brainer would be in spr = 1 situation where you need 33,3% to break even but here the spr is:

108,18-3,5= 104,68 bb smallest effective stack
flop pot 10,5 bb which means flop spr is now = 104,68/10,5 = 10

with an spr of 10 you would need 47,6% equity on average to break even.

What kind of realistic hands (barring idiot opponents) that are willing to go to a raising war on the flop would give your hand 47,6% equity on average?

Kreatief mentioned some hands you could be up against, but you are not even ahead against the (sucker end) bare straight here you would just have a bare nutflush draw here... Yes you are ahead of KKxxdd that stacks off here but that is pretty much the only hand I can imagine you are ahead of.

Going from spr = 10 to all in on flop generally means someone has (at least) the flopnuts, and you can't be ahead of any flopnuts here with your hand...

So if you can't raise, you can consider flatcalling but I don't really know what that additional value that would give you. You would want to hit the flush here on the turn and MAYBE your aces are live here but I would generally assume not. Here you have at best 9 outs to make your flush. If you consider your ace to be live than you can add 2 outs to that giving you 11 outs which would still not be enough for an all in, and also not enough for a call. If you call, there is 72 bb behind effectively, but on what turn are you going to be really happy apart from the flush and if you miss your flush the majority of the time, what are you going to do then...

Snap fold to the raise. This a straight always. How can he have a straight draw here? It's also never a bluff.

And like they said, you need 33% if you are only calling with the guarantee to see the river for free.

good that i postet this hand..i would do it again and again. I had a very similar hand where i had the 2nd nut str8 wit AA3x on 245 with a flsuhdraw. is it also than a fold? (villian was a fisch how minraises my bet on flop)

Hi,

your straight is irrelevant in that spot if you are sure your opponent only pot raises higher straights there.

Obviously this changes the lower the SPR is. In a 3b pot 100bb deep your hand is a snap shove.
