My impression is that, nowadays, those who play the Exchange Variation against the French are often misunderstood—they are not as looking for a harmless way to make a draw as the previous generations of players. Placing the king on the queenside is a dangerous provocation, as White's attack comes quickly. 10. b2b4 [%c_effect b4;square;b4;type;GreatFind;persistent;true] 10... d8e8  11. a2a4 [%c_effect a4;square;a4;type;Inaccuracy;persistent;true] A bit slow. 11... f7f6 Black wants to protect the e5-square against a knight jump, but 11...Ng6 also avoids this while also creating play on the kingside. 12. a4a5  12... c8b8  13. b4b5  13... c6d8  14. b5b6  14... a7a6 The first new move. Theory goes very far these days, even in not-so-good opening lines. 15. b6c7  15... d7c7 [%c_effect c7;square;c7;type;Inaccuracy;persistent;true] The wrong capture. Black has no problems after 16. d1b3  16... g7g5 [%c_effect g5;square;g5;type;Mistake;persistent;true] This offers the a-pawn for the h-pawn, but this exchange favors White.
