Hello,
Maybe you could raise a little larger preflop if utg calls a lot and opens hands like J10o from that position, 4x-4.5x is more standard when we 3bet out of position but this is just a small detail, your sizing is not bad.
Also I don't mind to flat call AQ from bb against utg's range, this goes better for full ring games but it can apply on 6-handed too and it's not a bad option.
I'm ok to check that flop sometimes, I can't really blame you, but I prefer to bet here against utg.
If we 3bet preflop is more standard to bet here anyways even if we have nothing.
1/4-1/3 of pot is a good sizing.
As played maybe you could find the fold at the end, it's a hard decision to make I know but such a move from him suggests that he has a hand that beat us and we still have 30+ bb behind to continue with the tourney.
