I'd start by check/folding the flop
Got zero FE, and drawing to 4 outs, possibly an A could be good, but its not like we can get more than 1 str value even then
We can't multi barrel, we can't vbet, we got zero FE and we got super slim equity makes for an easy decision.
Don't mean to be harsh, but if you can't rationalize this current spot you shouldn't be playing 50nl in prima, you ll get demolished there, ppl are actually good
Prima has the toughest 50nl/100nl player pool ( inb4 PS fanboys state otherwise )

Interesting I dont noticed players to be so good.
They are very agresive.
Sugest where to play in euro ?

I just ran a sim on this spot using Pio

My Assumptions:
Used my 3bet range for BBvBU which is 10.33%:
100% Frequency: AA, KK, QQ, JJ, TT, 99, AK, AQ, AJ, Ats, KQs, KJs,
25% Frequency: 88, 77, 66, 55, ATo, A9s, A8s, A7s, A6s, A5s, A4s, A3s, A2s, KQo, KJo, KTs, K9s, QJ, QTs, JT, T9s, 98s, 87s, 76s
Used a BU 3bet defense range of 22.81%:
100% Frequency: TT, 99, 88, 77, 66, 55, 44, 33, 22, AJ, AT, A9, A8s ,A7s, A6s, KQ, KJ, KTs, K8s, QJ, QTs, JTs, J9s, 109s, T9s, 97s, 87s, 76s, 65s,
75% Frequency: AQ
50% Frequency: JJ, A8o, A5s,A4s, A3s, A2s, KTo, K9s, K9o, QTo, Q9s, Q8s, JTo, J8s, J7s, T9o, T7s, 98s, 98o, 96s, 86s, 75s, 54s, 43s


Results were as follows:
FLOP: Kd 4d Js
It likes betting 87% of range for the 55% pot bet HERO chose. Has AQcc as a bet 98% of the time.

TURN: 9d
Assuming flop b/c it likes checking 100% of range

RIVER: Ks
Assuming turn k/k it likes betting about 20% of range with AQcc being a 100% check

So it actually looks like HERO played this hand very well if my assumptions and sim running abilities are adequate

I'm guessing his call range would be something like this :
TT-22,AQs-A2s,K2s+,Q7s+,J7s+,T7s+,97s+,86s+,75s+,64s+,54s,43s,AQo-A8o,KTo+,QTo+,JTo
thats 27% out of which optimistically speaking ( him folding 22 to 88 for example which will probably never happen ) he s folding around 8% of that on the flop

Guess it might be a bet optimally, could make a case for that, just wouldn't do that against a fish as it would be border line - which might be why im bad too though

Ran it again with a 27% defense and it came out pretty similar. 79% of range bet OTF with AQ at 95% bet. fwiw it has 22-99 as a fold most of time for IP when OOP cbet so against a (~10%) BB 3bet range they are making a decent sized mistake calling those hands. I guess we could check/call as an exploitative adjustment vs the field if people are indeed peeling this much.

I dont see how XF is good here.....
I think bet/fold ...bet/X./f is better than just XF

+1 4TM
-1 for Spitfireee in this hand
