Hero checks, BTN bets 18bb

The math

GTO answer: Call

AK with the nut backdoor flush draw and two overcards facing a turn barrel in a 3-bet pot. We have around 30 percent equity vs the value range and beat all the bluffs. Pot odds 42 to 18 (30 percent) makes calling correct. Raising blows up the pot OOP with a draw. Call, reassess river.
