Descriptive Notation - Chess Move Recording

Descriptive Notation

Definition

Descriptive notation is a legacy system for recording chess moves in which each square is named from the perspective of the player whose turn it is. Instead of today’s algebraic notation (e.g., 1. e4 e5), a move is written in terms of the piece and the square it travels to, such as 1. P-K4 P-K4. Files are labeled by the piece that starts on them (Q-file, K-file, QR-file, etc.), while ranks are numbered from each player’s side (1-8 for White, 1-8 for Black). As a result, the very same physical square has two different names depending on whose move is being described.

Naming Conventions

  • Files: QR, QN, QB, Q, K, KB, KN, KR (from a-file to h-file for White). The abbreviations stand for Queen’s Rook, Queen’s Knight, Queen’s Bishop, Queen, King, King’s Bishop, King’s Knight, King’s Rook.
  • Ranks: 1 – 8 from the viewpoint of the player making the move.
  • Pieces: P, N, B, R, Q, K. Pawns are often omitted when listing captures (e.g., P×K4).
  • Special symbols: × (capture), + (check), ++ (double-check), # (mate), O-O (kingside castling), O-O-O (queenside castling).

Every-Move Perspective

Because ranks are renumbered after every half-move, the square we call e4 in algebraic notation becomes K4 for White but K5 when Black is to move. This “shifting lens” is one of the main reasons descriptive was gradually replaced— computers, databases, and even casual readers prefer a single, fixed name for each square.

Historical Significance

• Descriptive notation dominated English-language chess literature for more than a century. The classic works of Capablanca, Alekhine, and Chernev, as well as U.S. Chess Federation magazines through the 1970s, were all published in this system.
• FIDE officially recommended algebraic in 1970, but many British and American publishers continued to use descriptive into the 1980s. The influential British Chess Magazine finally switched in 1988; the last U.S. Championship bulletin printed exclusively in descriptive appeared in 1990.
• Older players sometimes still “think” in descriptive, just as musicians may picture piano keys rather than sheet music.

Side-by-Side Example

The first eight moves of the Ruy López, Berlin Defence, as played in Lasker vs. Steinitz, World Championship 1894:

Algebraic           Descriptive
1. e4     e5        1. P-K4    P-K4
2. Nf3    Nc6       2. N-KB3   N-QB3
3. Bb5    Nf6       3. B-N5    N-KB3
4. O-O    Nxe4      4. O-O     N×K4
5. d4     Nd6       5. P-Q4    N-K3
6. Bxc6   dxc6      6. B×N     P×B
7. dxe5   Nf5       7. P×P     N-K4
8. Qe2    Nc5       8. Q-K2    N-B3

How to Read a Capture

Suppose a White knight on g5 captures the pawn on f7 with check. Algebraic: Nxf7+ Descriptive: N×KP + (“Knight takes King’s Pawn, check”).

Interesting Facts & Anecdotes

  • “K4” Means Four Different Squares!
    • White to move: K4 = e4. • Black to move: K4 = e5. • White notation speaking of Black’s last move: ...P-K4 = e5. • Black notation speaking of White’s last move: P-K4 = e4. This ambiguity caused many newcomers to misplay replayed games.
  • Fischer’s Hybrid Style
    Bobby Fischer grew up reading descriptive and occasionally mixed symbols, writing N-KB3 next to g1–f3 in his personal scorebooks when forced to submit algebraic scoresheets at events such as the 1970 Interzonal.
  • Computer Parsing Nightmare
    Early chess engines struggled to import historic databases because descriptive files contained human prose like “Kt-Kt5” (old English for knight) or “P-QR4 (?!).” Standardizing those archives into PGN took thousands of volunteer hours.
  • Philidor & Staunton
    The first printed chess book using anything like modern descriptive was Philidor’s 1749 L’Analyze des Échecs. Howard Staunton’s 1847 treatise refined the English conventions that lasted until the algebraic wave of the late 20th century.

Why Learn Descriptive Today?

  1. To access classic literature that has never been re-issued in algebraic.
  2. To read old magazines and newspaper columns exactly as they appeared.
  3. To appreciate the historical evolution of chess pedagogy.

Quick Conversion Tips

  • Pawns on the K and Q files become e and d files in algebraic.
  • Remember that “B” in descriptive stands for Bishop, not the b-file.
  • If you see “QR-4,” count four squares up the a-file for White or the h-file for Black.

At a Glance

Descriptive notation is part of chess’s rich cultural heritage. While no longer standard in modern tournaments, it remains a valuable key to the game’s literature and history.
