Grunch.

Hand 1 I like the preflop raise.
I would cbet flop.
C/r turn all in.
Ap kinda a toss up between a 3rd pot b/f and a check/soul read either way

Hand 2
I would cbet the flop
K baby baby is pretty much exactly what we wanted. (in terms of being the aggressor and a flop texture that our range stomps)
I like the turn raise (idea) just make it happen next time
Sizing is OK, I might go a little bigger, but that's nit picking
Folding river for sure.

Hand 3
Sucks.
In reality I don't even feel comfortable answering because my reaction to the bet would be radically different depending on the player and what kind of tells I could get out of them. Sometimes we look hard and find a call, sometimes we can snap fold, sometimes we can snap call.

Thanks for the responses all. For those who are interested:

Results:

Hand 1: Hero checks, and it checks through and hero takes pot with two pair KJ. CO had a weaker 2 pair on the turn; pretty sure other villain had some draw. Obviously I was pretty much in C/F mode at this point, but was more interested in the preflop/flop/turn in this hand. Especially turn... C/R all in? Wasn't sure. But thanks for the feedback. I only put "hero?" for the river just to not spoil everything - had no intention in value betting here.

Hand 2: Hero makes a bad call on the river. I knew it was a bad call the moment I called... it was one of those calls you make when you are just mentally not on your game. Villain had 5h4h for a rivered two pair and flush draw/gutshot draw on the turn.

Hand 3: Hero calls and villain tables K5s. Didn't want this hand to be just a bad beat story, but was really curious as to whether or not we can find a fold to an over-shove even though we have AA here...

grunch.

Hand 1 I dont like the preflop raise. KJo doesnt play great MW and its not a good idea to blot the pot OOP in a hand that is likely to go MW. As played fold flop, or c/r turn.

Hand 2 Raise bigger pre, as played fold river he has a bunch of 3x in his range.

Hand 3 Raise bigger pre. This spot really sucks, but I guess he has as many Qx as 5x in this spot so this is a call regardless, not super happy about it though
