I decided to play 3b or fold in this scenario, mixing KQo this time it was a raise. Not at all sure about my flop sizing, I think in retrospect I'd like to see myself go bigger and polar. Once I took that line and get raised I have to call right? Turn seems fine from my side but what do you think about his small sizing? And how would you play this overall?
