Semi-Slav — Botvinnik Variation
D44 · Played as black · Advanced · Queen's Gambit
Both sides give up material in the opening and neither king ever feels safe
The main line
1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 e6 5.Bg5 dxc4 6.e4 b5 7.e5 h6 8.Bh4 g5 9.Nxg5 hxg5
Strategic ideas
- Play both …c6 and …e6 to hold d5 with everything, then grab the c4-pawn and keep it
- Hold the extra pawn with …b5 and dare White to prove compensation
- Break the pin with …g5 even though it wrecks the kingside — activity beats structure here
- Sacrifice a piece with …gxh4 or accept White's Nxg5 — material stops mattering around move twelve
- Enter the most heavily analysed forcing line in all of chess, where knowing beats thinking
Key themes
- Dynamic — Pawns and pieces get thrown around from move ten — nothing about this position is static
- Attack — White's pawns storm the kingside while Black's queenside majority rolls the other way
- Counterattack — Black doesn't defend anything; every White threat is answered with a bigger one
Typical plans
The Botvinnik is what happens when both sides refuse to blink. Black holds d5 with both …c6 and …e6, grabs the c-pawn and clings to it with …b5. White responds by ripping the centre open with e4-e5 and Black's kingside gets shredded in the process. The resulting positions are the most analysed in chess — deep theory runs past move thirty in places, and both kings spend the game in mortal danger. Kramnik and Shirov built careers on it. It is not a line to improvise in.
Move by move
- d4 — White claims the centre.
- d5 — Black meets it symmetrically.
- c4 — White offers the Queen's Gambit.
- c6 — Black defends with the c-pawn, the Slav move order.
- Nf3 — White develops and controls e5.
- Nf6 — Black develops and defends d5.
- Nc3 — White develops and adds pressure to d5.
- e6 — Black plays …e6 as well. Both pawns now hold d5 — this is the Semi-Slav, and Black accepts that the c8-bishop is temporarily stuck.
- Bg5 — White pins the knight, the Anti-Meran move that invites the whole storm.
- dxc4 — Black takes the pawn and intends to hold it, which is the challenge the Botvinnik is built on.
- e4 — White grabs the centre rather than recovering the pawn. Material is officially secondary from here.
- b5 — Black defends the extra pawn. The queenside pawns are now a genuine long-term asset — if Black survives.
- e5 — White pushes past with tempo, attacking the f6-knight.
- h6 — Black asks the bishop the question, since the knight can't move while it's pinned.
- Bh4 — White keeps the pin, refusing to release the tension.
- g5 — Black plays the defining move — the only way to break the pin, and it hangs the g-pawn and wrecks the kingside for good.
- Nxg5 — White takes the pawn with the knight, offering a piece.
- hxg5 — Black takes back and is a piece up. White will collect the pawns on g5 and f6 straight back and get a raging initiative for the rest — the kingside is in ruins, the king can't castle safely, and every engine calls the whole thing balanced. Welcome to the Botvinnik Variation.
