When played C00 French:KIA 2. d3 d5, I choose to move my pawn
8. ... b4 to reply
After that, 'the battle at early game is held' with
9. a3 bxa3 10. Nxa3 Bxa3 11. Rxa3 and at the end of game, I forced to resign in game..
I feel that
8. ... b4 is my first bad move because it enabled 'battle' at developing phase when I actually not ready for that. What should the right move to reply
8. Bd2 in this case??
