dude you have to raise this river. its obvious villain has a made hand and doesnt want to give you a free card for the flush draw. Dont fold the river ever, call the 3 bet bet or cap if you are feeling lucky. I dont like your pf play. 3 betting 99 is a donkey play. Any hand like QT has 6 outs against you so I dont think its 3 bet worthy. Also, why wouldnt you wait until you know another heart wont come on the turn to bet the flop.
