Quick answer
Advanced Algebraic Notation is a notation skill: a position reconstructed from notation. Work from the first evidence position for Advanced Algebraic Notation, and begin by testing Kf8.
Begin from Kf8 in 4k3/8/8/8/6R1/8/8/4K3 b - - 1 1. List the fields needed to reconstruct the board and distinguish a position snapshot from a complete game record. The evidence answer is: Advanced Algebraic Notation: preserve side to move, check markers and move numbering while rebuilding the board. Candidate line: Kf8.
In the Advanced Algebraic Notation example, notice: side Black; pieces Black king e8, White rook g4, White king e1; legal first moves Kf8, Kf7, Ke7, Kd7, Kd8. Keep the piece census tied to this diagram—other positions with the same theme can look completely different.
What the record contains
The first evidence board tests a position reconstructed; the second board tests a position reconstructed. For the pair of examples, install A from direct FEN setup and install B from direct FEN setup. For glossary entries nearby, open the Chess Wiki plus the Notation And Tools hub. Then compare Notation with Chess Engine Centipawns, Standard Algebraic Notation, Long Algebraic Notation around round-trip reconstruction.
The two inventories make the distinction concrete. A contains side Black; pieces Black king e8, White rook g4, White king e1; legal first moves Kf8, Kf7, Ke7, Kd7, Kd8; B contains side Black; pieces Black king e8, White rook g4, White king e1; legal first moves Kf8, Kf7, Ke7, Kd7, Kd8. Compare the side to move before comparing the labels in the context of annotation punctuation.
Topic dossier for this page and board pair r1:4k3 | r2:8 | r3:8 | r4:8 | r5:6R1 | r6:8 | r7:8 | r8:4K3 / r1:4k3 | r2:8 | r3:8 | r4:8 | r5:6R1 | r6:8 | r7:8 | r8:4K3: start with round-trip reconstruction; then test annotation punctuation; keep a missing-history warning separate from the coordinate origin; use the tag pair identifying a game as the transfer check; and reserve a malformed token for the exception.
Reconstruction test
On the first board, calculate Kf8 after Kf8 and write down the opponent's best reply around round-trip reconstruction. On the second board, calculate Kf8 after Kf8 and check annotation punctuation. Use the notation to preserve state, not to infer history that the record does not contain. In this case the useful condition is a malformed token.
Key claim: Advanced Algebraic Notation is illustrated here by a position reconstructed from notation; the first concrete test is Kf8. The board anchor is 4k3/8/8/8/6R1/8/8/4K3; the example is intentionally narrower than the topic label and should not be generalised without checking the surrounding position..
Practical boundary: To answer “How can a player read advanced algebraic notation accurately and reconstruct the position or game record it describes?”, compare the recorded setup with Kf8 and the opponent's reply. The decision is useful only when the stated condition survives that concrete test on board 4k3/8/8/8/6R1/8/8/4K3. The evidence records The position tests the stated rule or record field; verify the relevant source when a procedural decision matters and the second board signature r1:4k3 | r2:8 | r3:8 | r4:8 | r5:6R1 | r6:8 | r7:8 | r8:4K3. The false-positive test is whether a missing-history warning appears without the coordinate origin, so the conclusion is useful only when the stated condition survives that concrete test.
Evidence positions
example-1: a position reconstructed from notation
Show answer
Advanced Algebraic Notation: preserve side to move, check markers and move numbering while rebuilding the board. Candidate line: Kf8.
Why this position is here: Advanced Algebraic Notation is represented by a position reconstructed from notation. This is a direct FEN setup with board anchor 4k3/8/8/8/6R1/8/8/4K3; no opening history is inferred from the diagram.
FEN: 4k3/8/8/8/6R1/8/8/4K3 b - - 1 1
Question: What is the first concrete decision in this advanced algebraic notation position?
Answer cue: Advanced Algebraic Notation: preserve side to move, check markers and move numbering while rebuilding the board. Candidate line: Kf8. The first candidate to test is Kf8. Replay Kf8 on board anchor 4k3/8/8/8/6R1/8/8/4K3 and write down what changes after it.
Evidence boundary: The position tests the stated rule or record field; verify the relevant source when a procedural decision matters.
Reading the record
Read the first example (id example-1) as a complete record: continuation Kf8, source pgn-specification. This is a direct FEN setup with board anchor 4k3/8/8/8/6R1/8/8/4K3; no opening history is inferred from the diagram. If A does not expose a position reconstructed from notation, correct the evidence before relying on the prose.
Read the second example (id example-1) separately: continuation Kf8, source pgn-specification. Its feature is a position reconstructed from notation; inventory side Black; pieces Black king e8, White rook g4, White king e1; legal first moves Kf8, Kf7, Ke7, Kd7, Kd8. Compare what changes between Kf8 and Kf8.
Missing information
The main mistake to avoid with Advanced Algebraic Notation is treating a compact notation field as if it encoded history or context that it does not actually contain. In A, the missing condition must be located in r1:4k3 | r2:8 | r3:8 | r4:8 | r5:6R1 | r6:8 | r7:8 | r8:4K3 after Kf8; in B, test it against r1:4k3 | r2:8 | r3:8 | r4:8 | r5:6R1 | r6:8 | r7:8 | r8:4K3 after Kf8.
For Advanced Algebraic Notation, the first board's evidence boundary (after Kf8) is The position tests the stated rule or record field; verify the relevant source when a procedural decision matters. The second board's evidence boundary for Advanced Algebraic Notation is The position tests the stated rule or record field; verify the relevant source when a procedural decision matters. If a trusted source or careful calculation changes the conclusion around the tag pair identifying a game, update both the evidence record and this article.
Practice protocol
decode one record at a time, reconstruct the board, and deliberately test one malformed or incomplete input. Start with A's side to move and r1:4k3 | r2:8 | r3:8 | r4:8 | r5:6R1 | r6:8 | r7:8 | r8:4K3; record two candidates, the reply to Kf8 and the correction. Repeat with B's side to move and r1:4k3 | r2:8 | r3:8 | r4:8 | r5:6R1 | r6:8 | r7:8 | r8:4K3; the changed board tests transfer rather than diagram memory.
After the drill, compare your notes with Chess Engine Centipawns, Standard Algebraic Notation, Long Algebraic Notation through the coordinate origin. Keep A's rejected alternative beside B's chosen line Kf8; this shows whether the conclusion survived a new board signature.
