Good fold?

really hard to tell without any read on the guy... could be set, J8? doubt it... K9, KT possibly? hard to tell...

i threw away a straight couple of days ago to the third spade on the river believing i made a good fold, couple of hands later the guy showed bottom pair after a big raise by him on the river... so in retrospect i figured my straight possibly was good...

Sorry forgot reads, not a ton of hands, like ~50, but he was a 14/9. Seemed fairly tag.

Cant be K10 really i dont see the guy falt calling on the flop with K10. maybe K9 suit, maybe a set since he limped. Hard one but i thik its a god laydown

could be calling with KT on flop with intention of bluffing the turn if checked to him... like if any overcard to the 9 would hit the turn if he puts you on a 9.. not likely though i'd say.. probably a set in my opinion

I like zee laydown. Smells like a 9T, 22 kinda hand to me, given his stats.

You have an aggression frequency number?

Would JQ stay in after turn here?

I think he might of had QJ but i dunno if a tight palyer would call the first bet on the flop unless he thought you were trying to buy it.
