THE STORY BEGINS

Every piece has a part to play.

In game three of the 1984 championship match, early queen exchanges leave a position that still demands exact calculation. Karpov’s rooks take central squares and the bishops gain useful diagonals. Study the recorded bishop manoeuvre alongside an earlier rook improvement preferred by the saved analysis.

  1. Queen exchanges do not remove tactical threats.
  2. Capture a central pawn only after checking the rook’s retreat squares.
  3. Compare a bishop improvement with bringing the remaining rook into play.
  4. A final attack can grow from earlier control of an open file.

Rxd5 wins the central pawn while keeping the rook active. The recorded bishop attack sends the rook to d6 before it captures on a6. These are concrete choices, not permission to grab any pawn with a rook. Check the bishop’s attacks and the available files before comparing the saved alternatives.

The game continued with Bc5, but the saved search prefers improving the rook with Rd1 first. The bishop move has a natural purpose, yet the order of improvement matters. Compare the direct rook activation with the recorded bishop manoeuvre, then follow how White eventually uses the d-file later in the game. The exercise asks for the stronger saved choice, not a claim that the historical winner always played the best move.

Rd1 gives the remaining rook an active file. White’s bishops and knight restrict several black defensive choices. The rook later reaches d7 while the other rook is exchanged. Compare the entry squares and the bishop support before judging the resulting material balance.

Bb6 attacks the rook on c7 while White’s remaining pieces stay coordinated. A useful bishop move can be the result of earlier file control and exchanges. List Black’s legal rook replies and what the white bishops and knight control after each one. The game ends in resignation here; the saved continuation is separate from the recorded score.

Result: 1-0. The recorded score ends here; it does not imply checkmate.
