Alekhine's defense is a duffer's defense. A grandmaster played this defense against me and I got a clear advantage into the middlegame, where, by virtue of his skill, he crushed me.
But the defense is easy enough to face. Getting an edge is easy:
e4 Nf6 e5 Nd5 Nc3! Nxc3 dxc3 Nc6 f4!
From here, you have a wide open, but safe center. Your doubled pawns help paralyze the enemy knight, and you have a great space advantage to the kingside. Develop your pieces and castle queenside.
I played this game in the Alekhine's Defense: Four Pawns Attack and I was crushed as white. I could not find a white improvement to this game which worries me on the viability of the Four Pawns Variation.
After review, it appears that I could have played Qh4 instead of Bxh6 for a worse endgame, but survivable. I did not play this opening to be barely survivable!
Thoughts?
