@Steamtyme, is it possible to note how many are seated at the table? that would affect preflop range.
Dealt to Hero [8s Js]
i like the preflop raise and c-bet. on the turn RRAI i'd have put him on a strong draw (and called). i tend to give people too much credit.

was he trying to bluff you off that or was he just a donk?
Hero [Jc 7c]
yikes. that turn and river is why i try to keep pots small after flops like that. very connected board. how often do you expect him to check behind you if you check the flop? i guess that's what determines whether i go for the steal (i'd rather not see turn+river if i bet) or play it more passively to get a cheap showdown.
without reads, villain could easily have raised AT, KT, QT, JT, TT (unlikely), T9, T8s, T7s, maybe other Tx. He also could have raised XsXs. there is a much wider range but the possibility that you are completely dominated by a straight or flush on the turn is real enough that we want to keep the pot small or get out IMO.
i'm probably not betting that turn and i'm probably check-folding the river. better spots to be had....
Hero [Kd Kh]
i might prefer a postflop 3bet there.
very frustrating turn. i would bet into his turn check and probably fold to a 3bet.
Hero [UTG] [Js Kd]
on the turn, your stack is only marginally bigger than the pot, correct? i think it's probably time to shove. the post flop check-call suggests either weakness or the nuts. either way, at these stack sizes i really don't like bet-folding to a turn check-raise. so i wanna get it in first to scare him off draws, weak pairs, top pair/weak kickers.
Hero [BTN] [Ks Ah]
not much to say about this one, seems fine.
Hero [LJ] [Jd Ks]
given that it's 3-handed i might bet the flop to isolate but that works.
