Stupid turn, what do I do???

[Vinny80]

Sorry about the hand not converted, I don't know any converter able to handle crypto HH in £.

Donk is about 24/10/2. Villain is pretty unknown, only about 30 hands so far, but it shows 21/21/9 but this is not enough to get a read in my opinion. In this hand, I flop the nuts, plus a straight flush draw. The turn is so bad given his range, what line do you like after villain checks here, I believe this hand is quite interesting and I really wonder what people will say about it...

EDITED: To add that stacks are 500£ so we each have about 350 left on turn ...
