I agree with CA , unless the dish is a tikka dish or something specifically requiring marinading I don't bother and find the chicken cooked perfectly nine times out of ten. I have to be honest and say I've never tried the yogurt method though so I'm not knocking it .. just never been dissatisfied with it un-marinaded way.
