Villain had played under 20 hands. He was 32/21 and cbet the flop 100% of the time ( 3/3 ) and cbet turn ( 2/2 ). That is all I have on him as he was very aggressive and didn't make it to one showdown.

Surely flushed me? I know I should have bet bigger on flop, prob more around the 0.10 mark. Should I have bet bigger on turn? Should I be calling hoping he shoving with a big missed hand, AK/AQ for e.g?
