Villain was new to the table and unknown.

I came up with this range for villain checkraising me, you think its valid?
88-QQ,AQ,AJ,KJ,KQ,QJs,JTs,T9s,98s,87s,7c6c + some random bluffs

What is his range for calling a shove?

unknowns have a pair + draw often enough that I'd do something other than folding

You're cr range looks ok...I'd have come up with something a little different but not significantly so. I would limit to the KJ combos to those that include the Kc, likewise for something like AQ (needs Qc). Also, I'd throw a couple more made flush hands in there...having the Ac takes a lot of possibilites off the table but he could have limp/called with any sc from 45 - 78.

Calling range if you shove will be any made flush or str8, any set. I guess he could call w/ KcJx as well. JT probably calls. Not sure about T9 - it probably shouldn't but it wouldn't shock me. Maybe AxQc. I think you fold everything else out. QxQc will call. QcJx as well. Seems like most of the folds you get will come from the random bluff part of his range and the wk pair + wk draw hands.

Unknowns don't usually check raise this big with a flush. He could have a straight, 999, two pair, or like QcJd. You have at the very least 40% equity against his range, and I can't really imagine anyone c/r/folding this board, so yeah, go all in.

I shoved, he called with 8 7, I sucked out.
Not sure if I made the correct play, but I guess its pretty close.

flop is probably a check, i can be convinced otherwise though

9 outs with two cards to come isn´t sucking out. Now if he would have had 87 and you would have won, now that would have been a suckout.

i think his range is pretty heavily weighted towards strong made hands <set+>, especially since you hold the A
i'd snapcall and reval turn

This is bad. If he has a combodraw he might shut down or bet the turn again. Any hand that clearly beat us will bet the turn again but we still have outs and we have to call/raise since he could obv. still be behind.

Now we are leading all combodraws. Basically almost any hand that raises this flop wants to get in. We have the best combodraw (nut flush draw + J pair) + we have outs 99,9 % of the time ---> shove.

Yes, I think calling is bad, cause I either hit my flush and don't get payed or don't hit and will have to fold cause he won't give me odds to keep drawing.
If I shove I have 40% even against most of his strong value hands, am a favourite against his weaker draws and fold out some stuff. So its pretty close between shoving and folding, but calling is the worst option.

Dude tptk + nfd Just ship it in. Worst case scenario you have like 35% equity.
