About the Alekhine Defense
Black answers 1.e4 with 1...Nf6, inviting White's pawns to chase the knight. The idea is to make White over-extend, then attack the big centre.
After e5 Nd5 c4 Nb6 d4, White has a big centre that can become a target.
Black hits the centre with ...d6, ...Nc6, ...Bg4 and ...c5.
The quiet 4.Nf3 (Modern) is White's safest way to keep a small edge.
