|-
| <math>A1</math>
| <math>S1 \cdot 3</math>
| Coordinate of chess board (it has size 8x8 so 3 bits are just enough)
|-
| <math>A2</math>
| <math>2 \times A1</math>
| square of the board (for example L00, 00L denotes e2 in [[Algebraic notation (chess)|algebraic notation]])
|-
| <math>A3</math>
| <math>S1 \cdot 4</math>
| piece (for example, 00L0&nbsp;— white king)
|-
| <math>A4</math>
| <math>(A2, A3)</math>
| piece on a board (for example L00, 00L; 00L0&nbsp;— white king on e2)
|-
| <math>A5</math>
| <math>64 \times A3</math>
| board (pieces positions, describes which piece each of 64 squares contains)
|-
| <math>A10</math>
| <math>(A5, S0, S1 \cdot 4, A2)</math>
| game state (<math>A5</math>&nbsp;— board, <math>S0</math>&nbsp;— player to move, <math>S1 \cdot 4</math>&nbsp;— possibility of [[castling]] (2 for white and 2 for black), <math>A2</math>&nbsp;— information about cell on which ''[[en passant]]'' move is possible
