First of all an example of a hand which occured about 8-10x /60000 hands so far:

-villain is a Reg with 31/22/10 and a c/raise of 9% On the flop and never folds to 3bets.

-I seem to misplay overpair+FD when the overpair is not KKxx or AAxx (KKxx +FD dominated
is a cooler IMO)

-I got 3 ways of adjusting in mind: 
a) Not 3betting QQxx and JJxx in that spot
b) checking my hand behind on the flop
c) folding to c/raise OTF

a) I like 3betting against this reg because he never folds to my 3bets and my hands got decent playabilty in position. If I get 4bet however, I have to give this hand up because it doesnt play well against his 4bets, which are almost always AAxx.

This hand plays okay multiway and HU too, so I'm not always sure what to do.

b) Seems just wrong because I make the POT bigger pre and now I don't want to get it in with a decent hand (or is this hand not strong enough?)

c) I'm a 35% dog vs the Nutflushdraw, so folding seems best.

How can I avoid this? By choosing c) or should I call it a cooler that my opponent had KK6hhx?
