I will provide my thought on the hand, but there isn't much to say. The play preflop was fine, other than the before mentioned sitting with too little at to big a blind. The flop play was HORRIBLE. Anyone who plays cash game will make a continuation bet on the flop and pick up the pot. You showed strength in a heads up match, allowing the first bet to pick up the pot. Ok, we don't bet the flop and let the turn come and help him. His bet on the turn was two parted. He was fishing to see where you were at and how much you liked your hand, and he was semi-bluffing the flush draw. An aggressive heads up player makes this play all the time with this weak of action post flop.

My advise to you is to quit playing cash game and stick to what ever you are good at. Cash game CAN NOT be played like a MTT and a MTT CAN NOT be played like cash game. I struggle in MTT's because I play them too much like a cash game.
