Against 2 guys, I don't find any reason to cbet because I guess only hands are coming with me includes Ace in a multiway pot. After I check flop, I like when villain lead and just call the turn. After he check the turn I was pretty sure I was ahead and I just try to make him come with me.

What do you think about flop check and river betsize?

Fine. Pretty confident we have him beat here and he might make the K-high herocall.

X otf is fine, turn call is fine but river bet is meeeehhhh... Tough to get value from worse here as TT~QQ are unlikely given pre flop action, all lower pairs just got counterfeit and we block a ton of KX combos. On top of that he has a bunch of nines in his range that can't be ruled out given action (stuff like T9s), I X behind....

Thank you for feedback! Villain showed TT.
