Normal Variation

The Normal Variation, 1. e4 Nf6 2. e5 Nd5, is the standard response to White's pawn advance in the Alekhine Defense and the gateway to nearly all of its main lines. On d5 the knight stands centrally and cannot be hit at once by the e-pawn, although a pawn on c4 can chase it again, and Black accepts that it may have to move more than once. The position is a hub rather than a fixed system. White's third move decides how much territory to take and how much time to spend taking it.

The most frequent choice is 3. d4, which supports the e5-pawn and frees the c1-bishop. Black normally strikes at the advanced pawn with 3...d6, and White then commits. One route is to grab space with 4. c4 Nb6, followed either by 5. f4 dxe5 6. fxe5 Nc6, the Four Pawns Attack, or by 5. exd6 exd6, the Exchange Variation. The other prioritizes development with 4. Nf3. A typical sequence is 4...Bg4 5. Be2 e6 6. O-O Be7 7. c4 Nb6 8. Nc3 O-O 9. Be3 Nc6, in which White keeps a moderate space advantage while Black, with the pieces developed, directs pressure at d4.

The second most popular reply, 3. c4, is the Two Pawns Attack, which harasses the knight without delay. After 3...Nb6, 4. d4 d6 usually transposes into the 3. d4 complex, while 4. c5 is the Lasker Variation, which pushes the knight back to d5. Among the quieter options, 3. Nf3 develops first and leaves White's pawn plans open. The Sämisch Attack, 3. Nc3, sidesteps the most theoretical and double-edged lines: after 3...Nxc3, recapturing with 4. dxc3 accepts doubled pawns for faster development, while 4. bxc3 strengthens control of d4. The Welling Variation, 3. b3, and the Buckley Attack, 3. Na3, are rarities.

The Normal Variation is one of the most frequently reached positions among named openings. Engines give White a slight edge, with 3. d4, 3. c4 and 3. Nf3 as their preferred moves. In practice the results are nearly even, and draws are unusually rare, which reflects the unbalanced games that arise once White establishes a broad center and Black begins to undermine it.
