Well 90% of the time his raise means he has 99+, AQ+.

Given the texture of this flop, flush draw, lowish paired board I could imagine an opponent pushing not out of weakness but because he doesn't want action from a flush draw. Also the opponent is pot committed with any decent bet.

He is pushing into 2 oppoenents so I think you will be facing an overpair a lot of the time. If he is pushing here with AK which is certainly a strong possibility he is still 3-1 to draw out on you.

Weight of evidence suggests I'm beat so without any reads I would fold here.
