Blockade the Passed Pawn: Abdusattorov v Praggnanandhaa, Checked

Part 1Wijk aan Zee 2026: the defending champion at 0 out of 2

The 88th Tata Steel Masters ran from 16 January to 1 February 2026 at Wijk aan Zee, a 14-player round robin at a classical time control: 120 minutes for 40 moves, then 30 more minutes with 30 seconds a move. Praggnanandhaa arrived as the defending champion. Nodirbek Abdusattorov eventually won the event with 9 out of 13, and Praggnanandhaa finished 11th. ^[5] ✓ Verified

In round 2 Praggnanandhaa, 0 out of 1, met Abdusattorov. The game came down to a rook ending in which White had a pawn more, and the question this article asks is the one every club player faces in such endings: what do you do about a passed pawn, whether it is yours or your opponent's?

Part 2What is a blockade, and why does it stop a passed pawn?

A blockade is a piece standing on the square directly in front of an enemy passed pawn, so that the pawn cannot advance. A passed pawn is a pawn that no enemy pawn can stop or capture on its way to promotion. The great teacher Aron Nimzowitsch made the blockade a central idea of positional play: a pawn that cannot move is not a danger, and a blockader that cannot be driven away is a permanent asset. ◐ Inferred

In the endgame the king is the best blockader, because it can never be traded for a rook or a knight and it is immune to attack by the opposing rook. A knight is also a fine blockader. A rook is a poor one, since a rook on the blockade square is stuck defending and the pawn's own king can chase it away.

A blockade has a cost: the blockader is committed, and the side blockading must not be dragged away by threats elsewhere. That is why passed-pawn endings so often turn on counterplay, and on whether the rook in front of the pawn or the rook behind it is more active. The rest of this article follows one game in which the blockade was available and Black did not take it.

Part 3How a quiet Queen's Gambit gave White a target on a7

Praggnanandhaa met the Queen's Gambit with the Exchange structure after 4...h6, and Abdusattorov replied with the quiet 6.Bf4. Bishops came off on d6, then on h7 after 9.Nh4 Bh7 10.Bd3. Abdusattorov said afterwards that the opening gave White what was wanted, according to the Chess.com report. ^[3] ✓ Verified

White's plan is simple: advance the a-pawn to a6. Black's pawns on a7 and b7 can then be fixed, and the a7 pawn in particular can never be defended by another pawn. Black answered 15.a5 with ...g6 and later 18...b5, which left a7 as a permanent target for a rook.

Stockfish thinks the position at this point is close to level. The pawn on a6 gives White a long-term target, not an advantage; it is a seed that bears fruit only if Black later gets the rook or the king overloaded. ✓ Verified

Part 4Two plans from the same rook ending

Between moves 19 and 30 queens and a pair of knights came off, leaving rooks and one knight each. Black's b-pawn became a passed pawn on b4 and White's a-pawn stood on a6. By the time of the key moments both sides held a passer, and the game would be decided by who could blockade and who could support.

Fast forward to the position after 42.g3, which is where the game turns. Both plans can be drawn on the same board.

Counterplay is the whole of Black's resource. White's rook on b3 guards the pawns on the third rank, and the white king has to keep the pawn on d4 safe from a rook that gets to a4.

Part 5The decisions that mattered

The evaluation stays within a quarter of a pawn for 30 moves. Then three decisions change it: one by Black that creates a passed pawn for White, one by White that gives most of the advantage back, and, in the next section, the decisive error. The graph shows them.

Part 6The turning point: 42...Rg2?

Black's b-pawn and White's a-pawn were then traded: 36...b3 37.a7 Rc7 and, after 40.Rb8 Rxa7 41.Rxb3, White keeps the extra pawn, the d-pawn, while Black's rook is active on a2. Stockfish rates the position after 41...Ra2 as close to level.

From here the rest is technique. After 47...Ke7?! (Stockfish prefers 47...Ra2) White breaks open the kingside with 48.f5, the king invades on f5 and f6, and 53.Rxh5 wins a second pawn. Praggnanandhaa captured on h4 at move 58, 59.d6 pushed the pawn on, and Black resigned after 60.Kd5.

Part 7What could Black have done? Take the square, not the pawn

The defence is a single idea: keep the king near the pawn and the rook active, and do not send the rook pawn-hunting. Stockfish's choice 42...Ke6 keeps the game close to level; its line runs 43.Rb6+ Ke7 44.Kd5, after which the white king leads the pawn but Black's king stays beside it and the rook keeps checking distance.

Part 8A fresh angle: the game was not lost on the pawn it dropped

The pawn that White won is not the story. What the engine sees is a passed pawn that ended up neither stopped nor supported, until the move in which Black's king stayed where it was. The clock suggests it was not a hurried decision, and a good habit follows: slow down at moments of calm, not only at moments of danger. ◐ Inferred

Part 9How to blockade a passed pawn in your own games

• Is the pawn passed, and who is nearer to its front square?
• Is my rook behind the pawn, or in front of it?
• Do the enemy rook's checks drive my king off the square?
• Can I give a pawn on the other wing to take the blockade?

Your turnPractise it

Set each position up, decide your plan before you look, then play it out against Stockfish to see whether it holds.

Part 10What to take away

• The king is the best blockader. It cannot be driven off by a rook, and it can never be exchanged.
• Race the kings first. Count the moves to the pawn's front square before touching the rook.
• Do not create a passed pawn for the opponent. 31...d4 gave White the central pawn the whole ending turned on.
• An extra pawn is not an extra win. White's edge was gone after 35.Ra8 and had to be won again.
• Errors come in calm moments too. Black's decisive move came with twenty minutes on the clock.
