The Alekhine Defense arises after 1.e4 Nf6 and falls under ECO code B02. The central concept behind the Alekhine is to invite White to push their center pawns forward, creating targets that Black intends to chip away at later. Although uncommon at the master level, the opening is fundamentally sound. White's most frequent reply is 2. e5, gaining space and aspiring to build a broad center with d4, then c4, and occasionally even f4, while Black bides time before counterattacking the overextended pawn chain. If White prefers to sidestep the main line, 2. Nc3 is a solid alternative that can transpose into the Vienna Game. There is also the sharp Krejcik Variation with 2. Bc4, which appears to offer a pawn but actually sets a trap: after 2...Nxe4, White plays 3. Bxf7+ Kxf7 4. Qh5+, regaining the material and stripping Black of castling rights. The opening bears the name of Alexander Alekhine, who first employed it in 1921, though the detailed theory and main lines were developed considerably later. With 47 million Lichess games across all rating levels, it is a well-established opening choice.

Move Diversity and Theory Depth
What players actually play after the opening moves depends heavily on rating. At 1200 Elo, the top reply is Nc3, played 39.9% of the time. There are 4 other moves seeing meaningful share, and 80% of games stick to established theory. Entropy: 2.33. By 2500, e5 dominates at 76% of replies; only 2 viable alternatives remain and 98.5% of moves are theory. Entropy drops to 1.06. That entropy collapse is the signature of a line where preparation pays off: at the top, players know the best move and play it.
Historical Trends
