Centre Counter Gambit Declined
After 1. e4 d5 2. e5 Bf5, Black most likely leads into positions reminiscent of the Advance Variation of the French Defence (once ... e6 is played). The notable difference is that the light-squared bishop is not entrenched behind the pawn on e6. This provides more breathing room for Black than in the customary Advance Variation of the French. Whether or not that is a "better" version of the opening for Black is unclear in my opinion, though others will disagree.
The main point is that you are starting with an aggressive gambit (Center Counter) and finding yourself in a much more defensive type of opening (French) after 3 moves or so! This explains why you might feel more uncomfortable when the gambit is declined. The same type of dramatic shift in "position type" occurs in the variation presented by MattHelfst.
I almost always win as black in the Centre Counter declined. You just need to block the e pawn from progressing. http://lichess.org/Komz7SiL
I think the centre counter accepted NF6 variation is great and can lead to some nice games, but I am really bad at the centre counter declined. Are there any good lines for it? What should I be trying to do with it in theory etc.?
