AAQQ hand is a fist pump call. Running 66J8 so it kills your queen really doesn't make sense. If you need an OESD to go with your bottom set and FD in a 3b pot you're playing way too tight. He will be jamming Txxx+ here (all these hands will have some other draw) especially if he has any inkling you're going to consider folding THIS hand ever. If you're ever folding AA+NFD in a 3b pot you've made a mistake somewhere.

KK73 hand this is a decent open limp spot given this guy is OTB. The rest is super read dependent, vs possible goof ball I'd just bet/cram. to me c/c has all the problems of bet/call except you've shown less strength so it will be more unclear what to do if you still have KK on blank turns. c/r then bomb most turns also seems better than c/c. c/c OOP doesn't/shouldn't scare people into not betting in future hands but c/r will. We are for sure not screwed against this guy's raise flop range which has lots of dominated draw+pairs.
