Trap in Alekhine Defense Opening
Continuing my series of thoughts on opening traps, I would like to mention a rookie trap / mistake I have encountered several times in blitz games playing Alekhine Defense.
It is a trivial opening position, but in several of my games white played 2. Nf3 or 2. Bc4, allowing black to simply snatch the pawn. I believe this is because the white players are used to playing 1. d4, and seeing black's response 1. ...Nf6. Thus, when they play 1. e4, they then automatically proceed paying little attention to black's knight.
