Villain check-raised me some hands before on a dry flop and I insta-folded (air). He seemed pretty aggressive overall so a flush draw might be part of his range for that donk-bet. On the other hand, we´re both pretty deep (40++ bb) and there´s only one player left to go on the bubble so he probably wouldn´t do that on a flush draw alone. Still, there´s only one hand I don´t beat.

What´s the correct way to play this?
