Hand History converted gives me [ img ] and [ URL ] which I cant use apparantly lol.

My plan was to check raise since villain had raised a few pots in position when checked to him, on second thoughts the number of hands I had on him makes this read a bit insignificant. When he bet I thought maybe TP, draws, Ax hands that paired with the board or a positional bluff so I raised. But when he 3bet me it was crossing my mind that he had a set (22, 66, 44), perhaps overpair 77-TT (surely he would 4bet QQ+ Pre and I had JJ) or TPTK. Surely he's not bad enough to have 53o/53s there. Regardless I ended up calling. Is it a fold to his 3bet on the flop? Perhaps I should've bet first not plan a c/r and when he'd re-raise call and re-evaluate on the turn or fold. Or perhaps am I always getting the money in here against this type of player?
