Hand 1: Raising is fine but think of it this way: It's a small sample size no way he threebets 20% of the time. Also just assume that no one is threebetting light until you see it over a large sample. Playing OOP in threebet pots is really tough and you may just want to fold just about everything besides AK/JJ and fourbet those hands. As tight as you play preflop its not exploitable at all.

Hand 2: I'd just threebarrel it. think of how many kings are in this guys range, like KQ only. As played I'd just fold, though c/r small and shoving the river isn't bad.

Hand 3: Since we're deep calling pre is fine, and of course you stack off here. KK/AA/AQ with card removal is much more likely than QQ/JJ, except that QQ/JJ is very likely range wise.

Hand 4: Raise it. I'd bet the flop to.

Hand 5: Can't fold no way.

Hand 6: Your not playing for stacks so don't raise the flop. Call down.

I think I agreed with Max on pretty much every single one!
