THE STORY BEGINS

Every piece has a part to play.

Frank Marshall introduced a dangerous pawn sacrifice against Capablanca in New York in 1918. Capablanca’s task was practical: meet the threats without letting material gain distract from king safety. The game is a study in defence under sustained pressure, not a recommendation to memorize a long opening line.

  1. After accepting a sacrifice, identify the opponent’s forcing moves.
  2. Defensive development is often worth more than protecting an extra pawn.
  3. Exchange an attacking piece when the resulting position is safe.
  4. Do not assume a successful defence ends the need to calculate.

A defensive manoeuvre can prepare the next active task. Capablanca plays 16.Re2. Black responds …Bg4, and the game continues into a forcing series of captures and checks. The extra material on the score sheet is not a substitute for understanding those threats. Compare the saved candidate lines and ask what each rook move changes about the defence of the king.

King safety is about actual lines, not only staying behind pawns. After …Qh1+, White plays 20.Ke2. The king will later travel through d3 to c2. This route looks unusual, but each step must be checked against the board rather than rejected by a general rule about castling. The saved variations show alternatives from the exact position, with all the rights and move history preserved.

Defence can be a sequence of useful steps rather than one brilliant block. The historical 24.Kc2 completes an important stage of the king’s escape. White has had to respond precisely while Black’s queen and bishops were active. Now look for ways to bring the undeveloped pieces into the game. Surviving a threat creates an opportunity; it does not remove the need to calculate the next one.

After defending, bring the piece that has been waiting into the game. With 31.Ra6, the rook leaves a1 along the open a-file. White’s advancing queenside pawn becomes a serious asset as the defence turns into counterplay. The lesson is the change of priorities: once immediate mating threats have been contained, improve the last inactive piece and keep checking the opponent’s forcing replies.

A CONNECTED IDEA

King safety depends on the actual lines

Compare Capablanca’s king route with Kosteniuk’s change of kingside structure. In both positions, count the opponent’s concrete threats rather than relying on appearances.
