200nl straight facing ai on turn on 3 suited board

[ItsTime4Nutz]

Villain is 50/40/3.7 - only 50 hands.

I'm checking this flop because i don't want to get c/r, and i can reevaluate turn. Since he pushes turn it seems to me like straight, draw or 2 pair, why should he push w made flush?
But overall i don't know whether it's a acceptable call or not?
