$40-80 Badugi Hand

[InWithTheBest]

Played some $40 mix this weekend at Bellagio. Im still bad at badugi but getting better. This hand occured at my second rotation of badugi against an opponent who had just hit a deuce after drawing at 7654x during the triple draw round. He proudly told the table he had broken a straight twice and than hit his card (clearly having no idea 7654x is bad).. Anyways..

Guy raises UTG the button calls and i three bet with 234x from the BB.. UTG instantly four bets and button folds. We both draw one. I decide my draw is better and bet into him, he raises really quick. I call and draw one and he stands pat. I check dark and than squeeze out a 7 to make my badugi. He bets I raise and he three bets very fast and very confidently. I decide to just call and check to him after we both stand pat. How did i do?
