What is the Alekhine Defense?

The Alekhine Defense starts 1.e4 Nf6. Black attacks e4 at once and invites White to chase the knight with pawns: after 1.e4 Nf6 2.e5 Nd5 3.d4 d6 White has a big centre, and Black's aim is to prove that it is overextended. It is a hypermodern, provocative defence named after World Champion Alexander Alekhine, less common than the main replies to 1.e4 but fully sound and a good surprise weapon.

Main ideas and plans

Your strategy is to undermine White's pawns with ...d6, ...c5, ...e6 or ...g6 and to pressure them with pieces, especially ...Nc6, ...Bg4 and the knight on b6. In the Modern Variation, 1.e4 Nf6 2.e5 Nd5 3.d4 d6 4.Nf3, White settles for a modest centre; you can pin the knight with ...Bg4 to weaken White's control of d4 and e5, or fianchetto with ...g6 and ...Bg7 to hit e5 from the long diagonal. In the Exchange Variation, 1.e4 Nf6 2.e5 Nd5 3.d4 d6 4.c4 Nb6 5.exd6, you choose between recapturing with the c-pawn for an unbalanced structure and recapturing with the e-pawn for quick, symmetrical development.

The most ambitious test is the Four Pawns Attack, 1.e4 Nf6 2.e5 Nd5 3.d4 d6 4.c4 Nb6 5.f4, where White grabs as much space as possible. The main line continues 1.e4 Nf6 2.e5 Nd5 3.d4 d6 4.c4 Nb6 5.f4 dxe5 6.fxe5 Nc6 7.Be3 Bf5 8.Nc3 e6 9.Nf3, and you must strike at the centre quickly, typically with ...Be7, ...O-O and ...f6, or with ...Qd7 and long castling, before White's pawns suffocate you. White can also avoid the main lines with quieter moves such as an early Nc3, which usually lets you equalise more comfortably.

Who is it for?

The Alekhine suits provocative, counterattacking players who are comfortable defending against a space advantage and enjoy hitting a centre rather than occupying it. It works well as a surprise weapon because many 1.e4 players know little theory against it. The risk is clear: if you react too slowly, White's extra space turns into a lasting bind. Learn first the role of the knight on b6 and the timing of ...dxe5 and ...c5 against the Four Pawns Attack, and have a plan ready against the solid Modern Variation, which is White's most common choice.
