Turn (89€) KJ5T

River (89€) KJ5T8
villain bets 32€ with 81€ behind, hero?

Put the rest in given that villain has so little behind? On one side i feel like most of the time we only get called by better hands, on the other side i think he will call with any King most of the time feeling commited to the pot having invested more than 1/2 of his stack. The small bet looks like a valuebet from a weak King but not sure. The only really strong hand he can have is Q9 imo.

Also not sure if the turn check is good...
I didnt play in 5 or 6 days and already feel a bit rusty lol

I'm not checking the turn. Part of me wants to shove the river and part wants to just call. I'd probably just call, though, because some rec players will just fold and only call with better!

I would have bet the turn again. Maybe the T gave him a better hand, but there are so many situations where it didn't. Don't overthink and keep getting money in with AA.

AP, yeah call the river. Maybe he's betting air, Kx, 2 pair, a straight, who knows. Like Javanewt said, he'll fold worse and most likely call a shove with better.
