bad beat? or bad play by me?

ok i dont know how to do a hand history so i'll just walk you through it

dealt to me A Kos, two callers one raiser i call his raise other two fold i put him on a pocket pair.

flop comes K 10 7 so i bet the pot he calls making it around 6 dollars(small change i know lol) turn comes making it K 10 7 Q so i think hmm i need to take this down right now and bet the pot again he calls i know he hasnt got a set cause he would have raised me (or atleast thats what i would have done)turn comes making it K 10 7 Q 9

ding finally it clicks he has JJ but im so far in i put the last of my money in and he does indeed have jacks... did i play this right? apart from throwing the last of my money away lol

TPTK is not that strong of a hand, after he called the pot sized bet on the flop, you have to be a little worried. I would slow down a little on the turn (maybe 1/2 - 2/3 pot bet) and if he called that one, then check the river. If he bets big or puts you all-in on the river, you're probably beat. (But honestly it would still be a tough fold...) Tough to figure anything out when you're out of position and being called down.

I don't see where he mentions this was NL, so I am going to assume it's limit. I think you played the perfectly. Yeh, so he sucked out on you, but you put the money in the pot when you had the best hand, and that's all you can expect to try and do, and over long term you would win more of those than lose.

2/3 pot on turn. Check/fold river.

This is NL because you can't bet the pot in limit.

Who says it isnt PL?
