After 3…Ne4 the position resolves into an open centre — the central pawns have largely been traded, so open files and piece activity decide the game rather than pawn play, with the d-file half-open for White and the e-file half-open for Black, white is ahead by a pawn.

Strategic ideas
Ideas for White
Return the pawn at the right moment, consolidate with e3/Nf3/Be2,the Ng4/e5 pressure with precise move orders.
Ideas for Black
Harass the e5 pawn and the Bf4 with ...Qe7/...Bb4+ tempo hits, then exploit the open lines and the eternal ...Ne5/...the ...Ne5 and ...f6 tricks.
Plans & pawn structures
- 1White plays down the d-file — with no White pawn there, a rook lift and pawn lever turn this file into direct pressure on d7.
- 2Black's counterplay runs down the e-file: it is half-open for Black, so the rooks swing there to hit e2 while White is busy elsewhere.
- 3In this open centre, development speed and king safety trump material — get castled, connect the rooks onto the open lines, and look for tactics against the less-coordinated side.
- 4Play around the fixed weaknesses: White's doubled e-pawns can be blockaded, piled on, and won in an endgame — trade pieces if you are attacking it, keep pieces on if you are defending.
Typical middlegame structures
The main line leads to an open centre — the central pawns have largely been traded, so open files and piece activity decide the game rather than pawn play. It leaves the d-file half-open for White, the e-file half-open for Black — that is where the rooks belong and where the middlegame is decided. Structurally, doubled white pawns on the e-file: fixed targets that reward the side with the pieces to attack them.
Traps & tactical motifs
The classic smothered patterns: careless Bf4-undefended lines let ...Ne5 or ...Qe7 hits win material by force.
How to Play Against the Fajarowicz Variation
- Target White's doubled e-pawns. Blockade the weak pawn on its square, pile pieces against it, and steer toward an endgame where it simply cannot be defended.
- Neutralise the e-file before Black owns it: challenge with your own rook, or close the file with a pawn so the opponent's main artery of play dries up.
- In this open position White must match development tempo for tempo — fall behind on castling and coordination and the open lines turn against you at once.
