In general, I'd say doing stuff like the K high (KQ) c/c down is probably unecessary high variance for how things are going for you.

Your JTo flop call on the low board float is probably not great. Better off floating with cards that he's likely to bluff. Also you don't even have a backdoor draw potential. I'd rather raise the flop if I wanted to continue with that hand.

TT hand - I'd probably bet turn for value. Don't expect him to go for the double value c/r. The river is probably close. It hits some of his air range, but also induces him to shove his air.

K8cc hand - why not bet the flop on A high board OOP? I really wouldn't shove that river ever, he's not gonna believe you rep anything credibly after checking the flop.

Rest of hands are lame obviously!
