ATo

The biggest part of his hands are air and lower pairs, I think this is a nice line. The raise on the River looks nice but do you think he'll call with less then the K? Is he capable of calling with A high (or even Q-high)?

Hi!

I totally like this calldown line being IP since you can control the hand very well and very often let him spew with total airball which is awesome. Unless you improve there is probably no combo which makes me wanna fold this hand....therefore brainless calldown is very solid and good move.

If you know him that he is mostly donking weakish hands then you can also go for turnvalueraise since the card is quite nice for you...it completes 0 draws and makes Kx less likely. Problem is that 3bet would be nasty and without any reads I preffer just calldown.

River raise doesnt make whole lot of sense.Now you even split vs worse Tx and if he was bluffing he wont call anyway. Appart from that if you face a 3bet I assume you didnt plan on folding even though such option is totally realisitic. So raising here basically goes for slight value vs A/Qhigh hands but these are not going to take this donking line this often.... so yes I would again just call due to card being pretty much complete blank and nothing changed.
