Alekhine's Defence

Alekhine's Defence is provocation with a philosophy: the knight hops into e4's territory, lures White's pawns forward, and then chips away at the overextended centre for the rest of the game. Hypermodernism at its spikiest.

Black's weapon·Tricky·5 movesIntermediate

Few openings have shaped modern chess as much as Alekhine's Defence. It has decided world championships, club trophies and late-night blitz games alike.

After 5.Bc4 the position resolves into a fluid centre — one side has staked a central pawn the other must decide how to challenge, so the structure is still being negotiated.

Position breakdown

A factual read of the position after the main line — the files, the centre, the pawn structure and king safety that decide how the middlegame is played. These are computed from the actual board, not generic advice.

Strategic ideas

Ideas for White

Grab space and hold it: the Four Pawns or Chase variations push Black back — but every pawn move is a target.

Ideas for Black

Harass the centre with ...c5, ...dxe5 and ...with precise ...c5/...Bg7 timing and piece pressure on d4/e5.

Plans & pawn structures

  • 1The centre is still fluid: decide early whether to lock it with a pawn advance or dissolve it with an exchange, because that choice picks the whole middlegame plan for you.
  • 2Trade correctly: before every exchange ask which piece benefits from the resulting square colours and pawn structure.
  • 3Watch the pawn breaks — both yours and your opponent's. In these structures the player who times the central break better usually wins the game.

Typical middlegame structures

The main line leads to a fluid centre — one side has staked a central pawn the other must decide how to challenge, so the structure is still being negotiated. No files have opened yet, so this is a manoeuvring struggle: improve your pieces and prepare the pawn break that will open the position on your terms.

How to Play Against the Alekhine's Defence

  • As White, strike at the fluid centre immediately with your own central pawn or piece pressure, before the opponent locks it into a shape that favours them.
