KK vs big river c/r

[Galapogos]

Villain is an unimpressive reg who runs 20/15/2.9 over a good sample. His flop aggression is a 4 and his river aggression is a 2. I haven't seen him putting his stack in very lightly except preflop. The BB is a loose passive fishy type player but I'm not sure the SB knows this since he just sat down a few hands ago.

I really should have bet the turn looking back now because I doubt he's calling with 67s preflop OOP. But his flop donk had me confused since I had never seen him do that before so I decided to take a safer line.

The only reason I want to call is my hand looks like it can't stand a c/r but I don't see why he'd make such a massive overbet on a bluff.

This looks like a fold. Any relevant timing tells?

[Galapogos]

No timing tells.

Unimpressive reg?
Big check/raise?

i'd fold as well

when he checks the turn you can easily bet here and it doesnt have to be a large bet. basically you're getting pwned by a 9 and beating just about everything else, but the other hands you're beating probably aren't going to put a ton of money in there, smaller pairs etc some hands like TT perhaps too. maybe half pot turn & river and puke to any CR

Fold, but about timing tells... do we consider calling here more if he instashoves?

[Sugar Nut]

Have you seen him donk before? I don't think a lot of ppl will take that line with better than KK on that flop.

I might be inclined to raise flop for value and to induce some spazzy stuff but to be honest "over a good sample" should give you more reads than just some numbers, so out of all of us you should be able to make the best decision in this hand.
