Boor Attack in Chess (Slav Defense Variation)

The Boor Attack might not be as famed as other classical openings, but it serves as an engaging subject for study and application among chess enthusiasts.

The Boor Attack is found as a type of variation within the Slav Defense.

Let’s take a look.

Initial Setup and Move Order in the Boor Attack

Unlike widely acknowledged openings, the Boor Attack anchors itself within a specific sequence within the Queen’s Gambit Declined, becoming apparent only as the game advances beyond the initial moves.

Core Sequence of Moves in the Boor Attack

Within this framework, the sixth move, 6. e4, notes the onset of the Boor Attack.

This particular move catapults the game into a territory that is complex yet ripe with strategic potential, offering white opportunities to explore diverse tactical ideas.

The evaluation is roughly +0.20 for white.

The Strategic Essence of the Boor Attack

In the Boor Attack, white’s pieces are relatively well-placed.

Central Domination

The move 6. e4 exemplifies white’s aspiration to dominate the center, a key principle in chess.

By attacking the d5 pawn and aspiring to establish pawns on d4 and e4, white strives to command the central squares, thereby providing its pieces with greater mobility and influence.

King Safety and Future Plans

White’s plan is also geared towards ensuring the king’s safety, typically via short castling. (However, this might come a bit later.)

The pawns on f3 and e4 not only control crucial central squares but also shield the king after it relocates to the kingside.

In the ensuing middlegame, white seeks to amplify its central presence, potentially enabling energetic operations on both flanks.

Countering the Boor Attack

While the Boor Attack bears its own strategic allure, its emergence on the board presents black with palpable opportunities for counterplay and resistance.

Striking at the Center

Black, in response, may look to challenge white’s central foothold, commonly by utilizing pieces to target the d4 and e4 pawns.

Taking on e4 with the d5 pawn is a common 6th move for black.

Pin the Knight

Bb4 to pin the knight to the queen is a common maneuver, often on black’s 6th or 7th move.
