I hope I can spark some interest in this opening for black by this post and I would like to know how often players are seeing these series of moves. I know it isn't played by the big GM people and I'd personally like to know why. I think this is fun and maybe I could bring it back into the light for a lot of players out there.
Alekhine's defense proceeds with the following moves:
There are three main variations I know for this opening: The four pawns attack, Modern, and exchange. I will show these in the order I stated them.
Also I am aware there is a Wikipedia page about all of this online. Don't just grab something from there, I want actual games and experience shown here. Have you ever played this?
Most people don't answer e4 with Nf6 because of the pawn push e5
penandpaper's first point makes sense. Second one... Not so much.
Actually it's true. It's exactly why defenses like this, the Pirc, Benoni, or Benko for example are not used at top levels as anything other than surprises. White has a choice between the theoretically most testing lines or a plethora of other lines that are equally, if not more, dangerous than that one. Giving White that many choices to a better position in the opening is not something that GMs like to do unless the tournament situation calls for them to try something different.
