Semi-Slav Defense: Anti-Meran Hastings Variation
Semi-Slav Defense: Anti-Meran, Hastings Variation
Definition
The Hastings Variation is a sharp branch of the Semi-Slav Defense that arises after White tries the Anti-Meran Gambit (5.Qc2 followed by 6.e4). The critical tabiya appears after:
1.d4 d5 2.c4 e6 3.Nc3 c6 4.Nf3 Nf6 5.Qc2 Nbd7 6.e4 dxe4 7.Nxe4 Nxe4 8.Qxe4 Bb4+ 9.Bd2 Qa5
The move 9...Qa5 (instead of the more common 9…Bxd2+ or 9…Qe7) constitutes the Hastings Variation. Black pins the d2-bishop, keeps tension, and prepares a timely …c5 strike.
Move-Order Map
- 1.d4 d5
- 2.c4 e6
- 3.Nc3 c6 (entering the Semi-Slav)
- 4.Nf3 Nf6
- 5.Qc2 Nbd7 (Anti-Meran setup)
- 6.e4 dxe4
- 7.Nxe4 Nxe4
- 8.Qxe4 Bb4+ (typical Meran-style check)
- 9.Bd2 Qa5 (Hastings Variation)
Strategic Themes
- Central tension: Black delays recapturing on d2 to keep the e4-queen somewhat exposed and aims for …c5 to challenge White’s center.
- Piece activity: The black queen on a5 eyes both d2 and c3, while the bishop on b4 restricts White’s knight. White typically replies with 10.a3 or 10.c5 to gain time.
- Imbalanced pawn structure: After the eventual exchange on d2, the resulting IQP-type positions give both sides chances—White gets space and activity; Black enjoys solid structure and counterplay on the light squares.
- Move-order subtleties: Because 9…Qa5 leaves the b4-bishop hanging to 10.Bd3, Black must be precise; meanwhile White must decide when (or if) to play a2-a3.
Historical & Naming Note
The variation received its name when it was analyzed and employed during several Hastings tournaments in the 1930s (notably Hastings 1933/34). It was popularized by British masters such as Sir George Thomas and William Winter, and later refined by Soviet analysts.

Typical Plans
- For White
- Push the kingside pawns (h- and g-files) to gain attacking chances if Black castles short.
- Occupy the center with Ne5 and f2-f4 breaks.
- Open the c-file after c4-c5, targeting Black’s queen and queenside pawns.
- For Black
- Timely …c5 or …e5 pawn breaks to undermine White’s space advantage.
- Exploit pins along the a5–e1 and b4–e1 diagonals.
- Exchange minor pieces to relieve pressure and steer the game toward an ending with the better pawn structure.
Interesting Facts & Anecdotes
- The line is sometimes called the “Curious Queen” variation because the early excursion of the black queen to a5 looks risky yet is perfectly sound.
- World Champions Garry Kasparov and Vladimir Kramnik have both used the Hastings Variation as Black when they needed a fighting, counterpunching defense against 1.d4.
- The ECO code for this system is D45. In mega-databases, over 1,000 games have featured 9…Qa5, with Black scoring a healthy 48–50%.
- Computer engines once thought the line dubious for Black, but modern neural-network assessments show it to be fully playable, offering double-edged middlegames.
When to Choose the Hastings Variation
Select this line if you:
- want to sidestep the heavily theorized 9…Bxd2+ main line,
- enjoy positions with hanging pawns or an isolated queen’s pawn,
- prefer middlegame complexity to immediate endgame simplification.
