I'm trying to come up with a range that doesn't let light 3 bettors autoprofit, not sure if I'm doing it right.
Let's say my UTG opening range looks like:
all pocket pairs, all suited broadways, AKo, T9-65s, all suited Ax
I get to 182 combos, or a 13.7% opening range from UTG. Is this too wide ?

Among this range, we can defend 3 bet by 4betting some and cold calling some.
AA,KK,AKo, 24 combos which we'll 4bet gii
TT,99,A5-A2 suited, 28 combos which we'll 4bet fold
AKs, AQs, QQ, JJ, 20 combos which we'll call a 3bet

In total 72 combos, out of 182 combos, that's 40% we are defending.
Are we overdefending UTG open?
Is it ok to NOT have a calling range and just 4bet/fold from UTG? If so, what would you do with AKs, AQs, QQ and JJ in a vacuum?
