villain was running like 33/11/0 but I only had 15 hands on him, so not very relevant.
However, before he min raised the flop he said the following sentence: "What did you hit?"
Then instead of calling or folding I started to think that he would be weak and I could raise him out of the pot. Do you think this is the kind of reaction opp wanted from me with his message?
