Positional Pawn Sacrifice: Gukesh's b6 Against Ding, Checked
Game 11 of the 2024 World Championship: a pawn given for the b-file, a worse position rescued, and what Stockfish 19 says about when the sacrifice is sound.
- plan
- outpost
- target
- The b-file
In short
- A positional pawn sacrifice gives up a pawn for lasting advantages (an open file, a weak king, a square, time) rather than for a quick attack.
- In game 11 of the 2024 World Championship Gukesh pushed the b-pawn to b6, let it be taken, and used the open b-file to squeeze Ding Liren.
- Stockfish 19 rates 17.b6 as the best move and the position as level, so the sacrifice was sound but not winning; Black's drift under steady pressure decided the game.
- The recipe: count what the pawn buys, check that the enemy cannot return the pawn with interest, and bring the rooks first.

Part 1Level at 5-5, three games to play
Game 11 of the 2024 World Championship in Singapore was played on 8 December 2024. Ding Liren, the champion, and the 18-year-old challenger Gukesh stood level at five points each. The match was the best of fourteen games and the first to 7.5 points would win, so the game was a hinge. [3] Verified
Gukesh, with the white pieces, chose a risky opening. Ding replied with a long think and a plan that, by Ding's own account, went nowhere. By move 15 Black was clearly better. By move 29 Gukesh had won. The story between those two points is a lesson in the positional pawn sacrifice.

Part 2What is a positional pawn sacrifice?
A positional pawn sacrifice is a pawn given up for lasting advantages rather than for a direct attack on the king. The compensation is structural: an open file for the rooks, a square for a piece, a weak enemy king or a few tempi of development. It is lasting because the opponent cannot cash it in by force. The chess is slow, and the extra pawn does not run away.
Three checks separate a sacrifice from a gift. Can the opponent give the pawn back with interest (a counter-sacrifice or a simplification)? Do your pieces already stand where the new lines lead? And what do you lose when the pawn leaves (a protected square, a shield)? If the answers are favourable, the pawn is an investment.

The same pawn push at two moments. The numbers above the boards show the cost of going too early.
Part 3A gambit with the colours reversed
The game began 1.Nf3 d5 2.c4 d4. Black grabs space in the centre, a Benoni-like structure, and White answers with 3.b4, a Reversed Blumenfeld Gambit with Benkö-like play on the queenside. Gozzoli calls 2.c4 a new choice in this match. After 3...c5 4.e3 White has the Blumenfeld a tempo up. [2] Verified
1.Nf3 d5 2.c4 d4 3.b4 c5 4.e3 Nf6 5.a3 Bg4 6.exd4 cxd4 7.h3 Bxf3 8.Qxf3 Qc7 +0.28about equal
The opening to move 8. Black has traded a bishop for a knight and White has a lead in space on the queenside. Verified
Ding thought for about 38 minutes over 4...Nf6 and for about 20 more on 5...Bg4, which left Ding with less than an hour on the clock early. By Ding's own account the time went on calculating lines that led nowhere. [2][3] Verified
Black's setup took the squares c5 and e5 for the knights, and after 9.d3 a5 10.b5 Nbd7 the picture was clear. White's pawn on d3 is weak, the b3 square is a hole, and the queen on f3 is awkward. Gozzoli wrote that the annotator was not optimistic about White's chances here. [2] Verified

- Black's knight squares
- pawn chain or line of force
Part 4Two plans from the same position
After 12...Nfd7 each side had a plan. White needed to finish development, castle and open the b-file. Black wanted to win the pawn on d3 with the knights from c5 and e5. Neither plan worked quickly. The player who found the right moment first would profit.
- plan
- key square
- plan
- target
- Black's grip
The same position, two plans. White's depends on the b-file, Black's on the pawn on d3.
Black's counterplay depended on the d3 pawn falling or on White's queen staying clumsy. White's depended on the b-pawn breaking through before Black consolidated. As Gozzoli notes, the idea of 11.g3, giving up d3 in return for development, is the concept behind the later play. [2] Verified
Part 5The decisions that mattered
Four positions decided the middle game. Each asks first and answers after. Think about the move before you open the answer.
Critical moment 1 of 5 · Move 11, White to play
Save the d3 pawn, or let it go?
- target
- key square
- Black's knights
Black's knights eye d3 and the queen on f3 is awkwardly placed. What is White's priority: to protect the pawn or to finish development?
Think it through on the boardWeigh the candidates
| Move | Stockfish | Verdict |
|---|---|---|
| 11.Nd2 11...Nc5 | −0.79Black slightly better | Guards the pawn but costs about two thirds of a pawn against 11.g3, since the queen and bishop stay stuck. Verified |
| 11.Qf4 11...Nc5 | −2.06Black winning | Loses material: Stockfish has Black about two pawns up. Verified |
| 11.Bd2 11...Nc5 | −2.15Black winning | Also loses material: Black is about two pawns up. Verified |
What Gukesh played
11.g3−0.24about equal
Gukesh plays 11.g3, preparing Bg2 and castling. The pawn on d3 is left to its fate.
Stockfish's first choice too. Depth 24.
What it revealed
White accepts that d3 may fall in return for development. The choice came after a long think and fixes the structure for the rest of the game.
- Verified Gozzoli writes that Gukesh thought for more than an hour in this position and that, with 11.g3, White accepts that the pawn on d3 is doomed.[2]
- Verified Stockfish agrees that 11.g3 is the best move.
Critical moment 2 of 5 · Move 15, White to play
Where do the pieces belong?
- target
- key square
- Black's grip
Black's knights are strong and the pawn on d4 cramps White. White has a queen on f4 and two undeveloped minor pieces. Which piece should move next?
Think it through on the boardWeigh the candidates
| Move | Stockfish | Verdict |
|---|---|---|
| 15.Nd2 15...e6 | −0.13about equal | The move that holds the balance: close to level, as Stockfish and Gozzoli agree. Verified |
| 15.Bd2 15...e6 | −3.12Black winning | Natural, but loses material: Stockfish has Black about three pawns up. Verified |
| 15.Qh4 15...Nexd3 | −3.32Black winning | Loses material: Black is about three pawns up. Verified |
What Gukesh played
15.Rd1−1.01Black clearly better
Gukesh plays 15.Rd1, lining up behind the pawn on d3. It is the first move where Stockfish gives Black a clear edge.
Stockfish preferred 15.Nd2 (−0.15); the game move gave up about 0.9 pawns. Depth 22.
What it revealed
The rook lines up behind a pawn, and the knight on b1 stays out of play. A natural-looking move cost White nearly nine tenths of a pawn.
What Stockfish adds Stockfish puts Black about a pawn up after 15.Rd1, against close to level after 15.Nd2.
Critical moment 3 of 5 · Move 17, White to play
Use the b-pawn, or keep it?
- target
- The b-file
The b-pawn has waited on b5 for seven moves. Black's queen stands on c7. Is the moment to use the pawn now?
Think it through on the boardWeigh the candidates
| Move | Stockfish | Verdict |
|---|---|---|
| 17.Ba3 17...Bh6 | +0.12about equal | A real alternative: Stockfish rates it level, a hair below 17.b6. Played one move later in the game. Verified |
| 17.Nd2 17...Qb8 | −0.65Black slightly better | Solid, but gives Black time: Black is about two thirds of a pawn better. Verified |
| 17.Kh2 17...Bh6 | −6.36Black completely winning | Too slow: Stockfish has Black winning material. Verified |
What Gukesh played
17.b60.00about equal
Gukesh plays 17.b6. The pawn attacks the queen on c7, and the b-file will open once the pawn is taken or traded.
Stockfish's first choice too. Depth 24.
What it revealed
The pawn is a sacrifice in the positional sense: White does not expect to win it back at once, but the b-file and the loose Black queen are worth more.
- Verified Gozzoli calls 17.b6 very accurate, since opening the b-file guarantees White a lot of play.[2]
- Verified Stockfish agrees that 17.b6 is the best move, with 17.Ba3 a close second. Gozzoli prefers 17...Qb8 to the 17...Qd6 played; Stockfish rates the two within a tenth of a pawn.
- Verified Gozzoli reports that Ding told the press conference Black had no chance in this position, a sign of low confidence.[2]
Critical moment 4 of 5 · Move 21, White to play
Bring the sleeping knight into play
- key square
- target
The knight on b1 has not moved since the first move. Black's knight has just arrived on c6. Where should the knight go?
Think it through on the boardWeigh the candidates
| Move | Stockfish | Verdict |
|---|---|---|
| 21.Nd2 21...O-O | +0.18about equal | Also fine: within a tenth of a pawn of 21.Na3, but the knight has fewer targets from d2. Verified |
| 21.Qe2 21...O-O | −0.14about equal | Slightly worse: about a seventh of a pawn in Black's favour. Verified |
| 21.Bf3 21...O-O | −0.30about equal | Worse: about a third of a pawn in Black's favour. Verified |
What Gukesh played
21.Na3+0.07about equal
Gukesh plays 21.Na3, heading for c2 and b4, to double on the b-file and play on the dark squares.
Stockfish's first choice too. Depth 30.
What it revealed
The last piece joins the plan. The knight guards b5, b4 and the pawn on c4, and prepares to double rooks on the b-file.
- Verified Ding said afterwards that ...Nc6 looked fine but Na3 had been missed, a very strong idea; the Chess.com report also has Ding saying Black had no chance after it.[3]
- Inferred The route a3-c2 is slow, but it returns the knight to the game without leaving the b-file undefended.
Part 6The turning point: 28...Qc8
From move 22 Black took the pawn on b6 and played on, with Gukesh doubling rooks on the b-file. The position was close to level in Stockfish's eyes, with White's pressure making Black's life hard. Then Black made two mistakes within three moves.
Critical moment 5 of 5 · Move 28, Black to play
Black to move: keep the knight guarded
- target
White's queen, rooks and knight all pressure the black knight on c6 and the b7 pawn. Black has about eight minutes left. Which move holds?
Think it through on the boardWeigh the candidates
| Move | Stockfish | Verdict |
|---|---|---|
| 28...Nb4 29.Nxb7 | +0.49White slightly better | Stockfish's choice: it leaves the knight active and holds the balance. Verified |
| 28...Qd8 29.Nxb7 | +7.37White completely winning | Loses: Stockfish has White more than seven pawns up. Verified |
| 28...Rd7 29.Nxd7 | +7.57White completely winning | Also loses: White is more than seven pawns up. Verified |
What Ding played
28...Qc8+7.34White completely winning
Ding plays 28...Qc8, which leaves the knight on c6 hanging to a queen sacrifice that wins.
Stockfish preferred 28...Nb4 (+0.49); the game move gave up about 6.8 pawns. Depth 22.
What it revealed
29.Qxc6 wins: after 29...bxc6 30.Rxb8 Qxb8 31.Rxb8+ White has traded queen and rook for queen, rook and knight, and Black's structure is wrecked.
What Stockfish adds The blunder costs nearly seven pawns. Stockfish sees a win for White.
29.Qxc6 bxc6 30.Rxb8 Qxb8 31.Rxb8+ Kh7 32.Bxc6 +6.96White completely winning
The queen sacrifice finishes the game: White comes out a piece up, with Black's pawns weak. Verified
Part 7What could Ding have done?
Black had two clear chances to keep the advantage. The first was at move 15, where 15...e6 would have kept the edge. The second was at the end, where 28...Nb4 would have held a worse position.

- outpost
28...Nb4 29.Nxb7 Bf8 30.Ra1 f5 31.Qh4 Kh7 32.Nxa5 +0.50White slightly better
28...Nb4 is the saving move: Black keeps the knight active and the position holds. Verified
- outpost
The defender's rule: when the opponent has sacrificed a pawn for lines, do not defend passively. Return the pawn or put a piece on the file yourself.
Part 8A fresh angle: the sacrifice was level
| Move | What happened | Stockfish's view |
|---|---|---|
| 15.Rd1 | Gukesh lines up behind d3 | Black's edge grows to about a pawn |
| 15...g6 | Ding misses 16.a4 | Gives back nearly the whole edge; 15...e6 was better |
| 17.b6 | The positional sacrifice | Best move; a pawn given, the position stays level |
| 21...Rd7 | Black drifts | Costs about seven tenths of a pawn; 21...O-O was the move |
| 26...e6 | Black loses the thread | Costs about a pawn and a half; 26...Rd6 held |
| 28...Qc8 | The blunder | Costs nearly seven pawns; 28...Nb4 held |
Both players erred more than once. The lesson is that a level sacrifice can still win games: after 17.b6 Black had to find accurate moves for twelve more moves against a growing b-file, and did not.
Part 9How to use a positional pawn sacrifice
The recipe
- Find a targetLook for a weak pawn, an exposed king or an unprotected piece on a file or diagonal that the pawn can open.
- Bring the pieces firstA rook on the right file, a queen behind it, a knight heading for the key square. Prepare before you sacrifice.
- Count what the opponent can returnCan the pawn be given back with a trade or a counter-sacrifice? If so, think again.
- Play it with a threatThe pawn on b6 attacked a queen. A sacrifice with tempo wins time as well as lines.
- Keep the pressureDo not rush to win the pawn back. Add pieces to the file until the opponent errs.
- Do my rooks have a way onto the file?
- Can the pawn be taken with a gain of time?
- Is my own king safe if the position opens?
- Is there a quiet move that keeps my position safe instead?
Your turnPractise it
Set each position up, decide your plan before you look, then play it out against Stockfish to see whether it holds.
White to play. The b-pawn stands on b5 and Black's queen is on c7. How do you use the pawn?
Hint
The pawn can attack the queen.
A good answer
17.b6 is Stockfish's choice: the pawn attacks the queen and opens the b-file.
Black to play. White's pieces press on c6 and b7. Which move holds?
Hint
Move the knight from the attacked square.
A good answer
28...Nb4 is Stockfish's move and holds; 28...Qc8 loses to 29.Qxc6, and so do the quiet 28...Qd8 and 28...Rd7.
White to play. Black's knights are on c5 and e5. What is the safest developing move?
Hint
Develop the sleeping knight.
A good answer
15.Nd2 is Stockfish's move; the rook move played in the game was worse.
Part 10Takeaways
- A positional sacrifice buys structure. The pawn is paid for with a file, a square or time.
- Pieces first. The same push was sound at move 17 and a mistake at move 11.
- A sacrifice with tempo is better. The pawn on b6 attacked the queen.
- Quiet moves matter. 15.Rd1 looked natural and gave Black the edge.
- Defend actively. Passive defence of a positional sacrifice rarely works.
Questions readers ask
What is a positional pawn sacrifice?
It is a pawn given up for lasting advantages such as an open file, a strong square or time, rather than for a direct attack. The opponent cannot cash in the extra pawn quickly, and the compensation lasts.
When should I sacrifice a pawn for the open file?
Sacrifice when your rooks can use the file before the opponent can defend it, and when the pawn cannot be returned with interest. Prepare the rooks first, then open the file with a threat.
Why did Gukesh play 17.b6 against Ding?
Stockfish rates it the best move, by a hair over 17.Ba3. The pawn attacked the queen on c7 and opened the b-file for the rooks, giving a pawn for lasting pressure while the position stayed level.
How did Gukesh beat Ding in game 11 of the 2024 World Championship?
Gukesh sacrificed a pawn with 17.b6, kept the pressure on the b-file and won when Ding blundered with 28...Qc8, allowing the queen sacrifice 29.Qxc6.
Is a positional sacrifice risky?
It is risky when your pieces are not ready, as in the same push at move 11, which just loses a pawn. With the rooks ready it is an investment with a clear return.
