I think calling the 3 bet is fine given we're heads up and my hand is coordinated with a suit. He could easily have a high pair that a rundown would play well against. It's also possible he 3 bet with a higher rundown type hand though. On the flop I think it's an easy call with the flush draw and BDSD, I have many good turn cards and position. On the turn when he checks it over to me I'm thinking he's got some AAxx or another high pair that is checking the flushing turn and I pot it. I wasn't worried about the paired board bc I don't think he's 3 betting me with many hands having the 3 along with either the 5 or the 9. When he raises it I only had $13.95 left behind so I called it off with the T high flush. My main questions are should I be taking the paired board as more of a threat and should I be playing the T high flush less aggressively on the turn?
