If u all give up , I would ask u is this the best defence for white ? Since u dont know ?
French defence problems for black in advance

6...Ne7 isn't the only move. There is 6...Nh6, 6...c4 or ambitous 6...f6 for a start. Would probably play the the classic 6...c4, were there is a long manovering game. Your plus/minus symbols are particularly irrelevant there, and it is more important if have idea of each sides plans.
Problems must be answered in game or diagram, or position form .Thanks
