Day 11of 14, Master the Fundamentals with Capablanca

The Castling Race

Capablanca vs Janowski · St. Petersburg 1914 · The Castling Race

When the kings castle on opposite sides, the game becomes a race and the rules change. Manoeuvring is a luxury; every move that does not advance a pawn toward the enemy king is a move given away. Capablanca had already removed Black's compensation for his doubled pawns by trading a bishop, and when Janowski answered the opposite-side castling with a slow knight move instead of a pawn storm, the race was effectively over. Take one idea into your games, with opposite castling, push the pawns in front of their king and count tempi, not beauty.

Three ideas you'll take from this endgame
01

Pawns first, pieces later

In a castling race the pawns open the lines and the pieces follow. Janowski's 10...Nh6 was a developing move in a position that had no time for one.

02

Remove their compensation

Black's doubled c-pawns were paid for with the bishop pair. 7.Be3 invites the trade, and once a bishop goes the weakness remains without the payment.

03

Count tempi honestly

Even Capablanca loses time here with 9.Qe1. In a race a slow move is not a small error, it is a move handed to the opponent.

The Big Idea

Two attacks, and only one of them starts

The Exchange Ruy Lopez gives Black doubled queen-side pawns in return for the bishop pair, and Capablanca's whole opening scheme is designed to collect the debt without paying the interest. With 7.Be3 he offers the trade of dark-squared bishops, and after 7...Bxe3 8.fxe3 he has three things at once: one of Black's bishops is gone, the f-file is open toward the king-side, and the doubled e-pawns now control d4. When Janowski castles long, the position turns into the purest kind of race, White's pawns go at the black king on the queen-side and Black's should go at the white king on the king-side. What decides it is not evaluation but speed. Capablanca is not perfect here, 9.Qe1 is slow, but Janowski answers with 10...Nh6, a piece move in a position that demanded pawns. By the time the black attack is ready to begin, 15.b5 has already opened the b-file. In your games, when the kings go to different wings, start pushing immediately.

How the Endgame Arose

An Exchange Ruy Lopez, and a bishop traded on purpose

Capablanca met the Spanish with 4.Bxc6 dxc6 and then chose 5.Nc3, a line he had discussed with Alekhine, who used it in the same tournament against Emanuel Lasker with a fine position. The strategic thread is simple. Black holds the bishop pair as compensation for a damaged structure, so White trades a bishop off at the first opportunity. After 7.Be3 Bxe3 8.fxe3 the compensation is halved, the f-file is open, and the doubled e-pawns are doing useful work covering d4. Janowski then castled queen-side, boldly and characteristically, and the race began.

Stop and Assess

The kings are on opposite wings. What is the plan?

Black has just castled long while White is castled short. Material is level and both sides have exactly the same instruction: attack the king in front of you with pawns. The only question that matters now is who does it faster. Stop and assess before you read on.

The kings have castled on opposite wings. What should each side do, and what is the one thing neither can afford?

Ask which pawns can advance toward the enemy king without exposing your own. Then ask what a quiet piece move costs in a race. Think, then reveal.

Reveal the assessment

White's method (Capablanca)

  • Storm the queen-side. 11.b4 and 12.a4 head straight for the black king.
  • Open a file. 15.b5 breaks the shelter and the b-file becomes the highway.
  • Use the extra tempo. Every quiet move Janowski makes is a move White spends attacking.

Black's problem (Janowski)

  • A piece move in a race. 10...Nh6 does not advance a pawn toward White's king.
  • Compensation already gone. The bishop pair was traded, the doubled pawns remain.
  • An attack that never starts. By the time the king-side pawns move, the queen-side is open.
The Plan

Storm, break, and invade

Capablanca runs the race in three stages. First he storms, 11.b4 and 12.a4 push directly at the king with no preparation beyond what is needed, because in this structure the pawns are the attack. Second he breaks, 15.b5 opens the b-file at the moment Black is least ready, and after 15...cxb5 16.axb5 a5 the black king's cover is permanently compromised. Third he invades, the knight comes to d5, the rooks arrive on the open files, and 27.c6+ finishes the job by dragging the king into the open. Janowski meanwhile has spent his moves on Nh6, Nf7, f6 and Ng5, all reasonable-looking, none of them a pawn moving toward the white king. In your games, judge a castling race by a single number, how many moves each side has spent advancing pawns at the enemy king.

The Critical Moment: Think First

White has advanced on the queen-side and Black has spent his moves repositioning knights. The pawns are as far forward as they can go without a break. This is the moment the race is won or lost.

White to play. The pawns are advanced and the black king is behind them. Which move opens the position?

15.b5: the break that opens the b-file against Black's king
Reveal the move and the why

15.b5, the break the whole attack was built for. After 15...cxb5 16.axb5 a5 the b-file is open, the black king has lost the pawn cover it was relying on, and every white piece has a route in. This is the moment to note what made it possible: Black's doubled c-pawns, created back on move four, are exactly what let the b-pawn break open the position so cheaply. The structural decision and the attacking decision are the same decision, made ten moves apart. In your games, when you storm a castled king, look for the pawn break that opens a file rather than the one that simply gains space, and time it for the moment their counterattack is still a move or two away.

Push the Pawns, Count the Tempi

Open the file, then drag the king out

With the queen-side open the invasion is quick. The knight reaches d5, the heavy pieces occupy the c- and d-files, and 27.c6+ is the final blow, a pawn check that pulls the king onto squares where the rooks and queen are already waiting. Black's king-side counterattack never produced a single threat.

The finish is short. 28.cxd7 Qxd7 29.d5 and the passed pawns and the exposed king decide together, with 31.Qc6 ending matters. The whole game is one lesson repeated: in an opposite-castling race the pawns are the attack, and the side that starts first usually finishes first. Carry it into your games, when the kings split, put a pawn in motion on the very next move.

Principles to Take to Your Own Board

This game is over. Your games are where it matters.

1 · With opposite castling, push pawns immediately.

The rule: the pawns in front of the enemy king are your attack, so start them at once. In this game: White pushed b4 and a4 while Black played knight moves. In your games: when the kings split, advance a pawn on the next move.

2 · Never touch the pawns in front of your own king.

The rule: in a race, your own cover must stay intact. In this game: White's king-side pawns hardly moved all game. In your games: attack with the pawns far from your king.

3 · Remove their compensation.

The rule: when the opponent has a weakness paid for by an asset, trade the asset off. In this game: 7.Be3 removed a bishop and left the doubled pawns unpaid for. In your games: exchange the piece that justifies their structure.

4 · Break to open a file, not to gain space.

The rule: in an attack, the pawn break that opens a line beats the one that merely advances. In this game: 15.b5 opened the b-file straight to the king. In your games: aim the break where your rooks can follow.

5 · A quiet move in a race is a lost move.

The rule: in sharp opposite-castling positions, tempo counts more than refinement. In this game: 10...Nh6 lost the race, and even 9.Qe1 was slow. In your games: ask whether each move brings the attack closer, and if not, find one that does.

Test Yourself

Five questions before you go

1 · Why are pawns the attack rather than pieces?

Because a castled king is protected by pawns, and only pawns can remove them cheaply. Pieces alone cannot open a file. In an opposite-castling race the pawns do the opening and the pieces do the invading, in that order.

2 · What was wrong with 10...Nh6?

Nothing, except the position it was played in. It develops a piece and improves nothing about Black's attack. In a race that is a tempo handed over, and here it was the tempo that let 15.b5 arrive before any black threat existed.

3 · Why trade bishops with 7.Be3?

Because Black's bishop pair was the compensation for his doubled c-pawns. Trading a bishop keeps the structural weakness and removes the payment for it. It also opened the f-file and let the doubled e-pawns cover d4, so one move achieved three things.

4 · How do the doubled pawns help White's attack?

They make the break cheap. With pawns on c7 and c6, White's b4-b5 hits a structure that cannot hold, and after the exchanges the b-file opens straight onto the king. The opening weakness and the middlegame attack are the same idea at different stages.

5 · Was Capablanca's play perfect here?

No, and it is worth being honest about it. 9.Qe1 is slow in a position that punishes slowness, and Black could have taken the initiative with an immediate pawn storm. Capablanca won because his opponent was slower still, which is exactly how most races are decided.
