White does have a comfortable game after 3.exd5. The problem is that Black is even more comfortable! The position is already just about equal objectively. And usually, when Black achieves equality that early, Black can expect to outplay his opponent.
Strong players sometimes do play the French Exchange as white, but they don't play it to be comfortable, they strive to create sharp positions. The problem is that 3.exd5 exd5 doesn't lend itself to sharpness. As long as Black is vigilant, he can usually draw, and often wins.
One really famous game was Mikhail-Gurevich vs Nigel Short. Gurevich as white only needed a draw to advance to the next stage of the World championship. Short needed to win. Gurevich played the Exchange variation, reached a drawn position, but couldn't finish it.
Here's that game.
Hey, learning the french. Can someone please tell my why white wouldn't want to play 1.e4 e6 2.d4 d5 3.xd5 ?
To me it seems that white will have a comfortable game and not really have to worry about closed positions.
Any help?
