75s from MP, turn+river play

Please no comments on the pre open Its Big 5 from ps .fr

I just want to know if you would bet this turn or rather check behind. And how you would proceed river in both cases.
Also this was a player who just came at our table , so no reads yet.

Altough its basically one of the worst turn cards in the deck for me I am still not 100% sure if checking behind is the best option vs betting.
