Santo 3 betting preflop here is honestly really bad. Don't ever 3 bet an utg open "to get a sesne of where you're at." If he calls or raises, you're in terrible shape, dominated a ton and have cut out loads of your implied odds vs his bigger hands by inflating the pot/or caused him to 4 bet and stopped yourself from beinh able to see a flop. If you feel he folds a lot to 3 bets when he opens utg then pick hands that don't play so well IP to 3 bet bluff, this is pretty much never the case here though so 3-betting is dire.
