Hello

On that spot I'm 3betting AA-JJ,AKo-AQo,AKs-ATs,KQs-KJs,QJs,JTs,[50]A5s-A2s[/50]
CO calls something like JJ-55,AQo,AQs-ATs,KQs-KJs,QJs,JTs,[35]QQ,44-22,AKo,KQo,A5s-A2s[/35]. I have 51.7% equity with no set, no dp.

To find the best cbet strategy (without a solver) I've made some assumptions (which are possibly wrong)

-I have a slight equity advantage but no nuts advantage
-Not having very strong hands like DP+ prevent me to cbet big
-Cbetting big with overpairs OOP on that flop seems to be pretty unconfortable
-80% of my range is Ahi or draws

So in that spot I thought I have to cbet <50% PSB and not checking so much to be able to cbet a lots of draws that are not able to x/c like BDFD BDSD because if we decide to bet bigger we cannot bet very frequently. Obviously a friend of mine have a PIO simulation that showed the opposit: Cbet 0.75psb 83% of the time (or 33% pSB 90% of the time)

What's wrong in my thinking process?
What is the best strategy for you on that spot and why?

Thank you very much guys and my warmest season's greetings to you and your family :)
