He guys,

here's a hand i played yesterday and would highly appreciate some oppinions.

Pre villain minopens from the button, which widens my button calling a bit.
I think 3bet with such a hand doesnt archieve much but feel free to correct me.

OTF i went for a c/r cuz i thought i can rep a stronge range here (sets, straight, vulnerable overpairs like 77,88, combodraws like As5s...) and my first impression of this limit (my first stab on nl10) is that the regs cbet way to light in many spots and react way to nitty to overall aggression.
After villains call i give him some medium strong hands like overpairs, overcards with FD and rarely played very strong hands cuz i also assume that this regs tend to play theyre nuts faster especially on wet boards and cap theyre calling range often very hard.

OTT i go forward barreling cuz even if i think the K hits villains range better than mine i think i have a good range advantage here.

OTR i try to evaluate a good shoving range.

I would shove any sets,straights (13 combos) and would also shove All suited A4,A5 combos except the spike ones, which would block villains Flushdraws. then coming up for the villain depending shoves - if villain would be to nitty OTR i would add more bluffs but dunno which would be best to be honest.
i have a bit more than 6$ left.

Any ideas here for the river play guys?
Im also interested in how you guy would define a good Flop c/c range and how would you play Hands like A2s,A3s ,77 in this spot?

thanks in advance for your ideas!
