I'm posting this on both mid and high since a lot of posters might only browse on of them.

I've had some thoughts with fine-tuning my 3bet ranges lately and wanted some input.

For a long time I thought stuff like JJ,TT and AQs where too loose to 3b when IP vs decent reg utg range, but they all have +54% vs a realistic flatting range and have enough odds to flat vs a tight 4b range too, not to mention you deny others equity from making profitable calls behind, and obv profit when utg folds. So I think it's definately something I should add into my 3b range, for a long time I just flatted these hands.

I've also been toying around with mixing hands into both 3b and flat ranges, mostly the hands I 3bet for value so QQ+,AK. I've thought of 3betting these 50% vs utg 3x sizing. There are a lot of things to consider here though, should I 3bet QQ% more than 50% because it is much more vulnerable than AA and would rather get hu vs utg, or 3bet AA more than 50% because it is so much ahead compared to anything else?
If you had to choose one of these to 3bet more often than the other, which would it be? Let's assume we are mp vs utg, and co and btn 3bet 5% both, sb 3bets 8% and bb 3bets 4%, so we get squeezed roughly 22% of the time not taking into account our blockers to their 3b range.

Opening sizing also matters, I'd want to 3bet the top hands a higher % vs 2,5x and 2x, with very rarely flatting vs 2x.

I guess that's it for now, comments and thoughts welcome.
