Fancy play syndrome.

preflop is fine. flop I like a lot. turn is probably ok. you're representing a hand that's about to give up (or one of those idiots that checks with the lead after the draw hits, but I don't think that's the case here). it's doubtful he has an A. most likely he has a smaller heart or absolutely nothing. I think the nothing is a significant chunk and that extra bet from him is nice. if he bets, I don't like checkraising. I'd probably donk the river and 3-bet it. you'd have to call a cap though since he's aggressive and your line is very suspicious. the river is not as obvious as it looks since he might have checked nothing and I think he'll take a stab with most worse hands, maybe even black kings as a bluff. an A might value bet though I don't think he has one. betting still is probably best but it's not automatic IMO
