basic line where I think I am losing money - 5/10 6max

[punter11235]

I think I started making some stupid things recently so I am questioning basic lines... Villain in this hand in unknown 30/10 after 50 hands. No other reads yet.
I dont know what to do on the flop... I suspect calling is standard but what's my plan on the blank turn ? check-fold ? bet fold ? What's standard here ?
