Answers to Questions (FAQ)
What is UCI notation? (Definition)
In chess, the UCI notation (for Universal Chess Interface) is the writing used by the UCI protocol which allows communication between chess software.
How does UCI notation work?
The UCI format describes the movements of the pieces by encoding the start and end coordinates of the piece. The moves are therefore noted with 4 characters (letter, digit, letter, digit).
Example: d2d4 movement of the piece in coordinate d2 towards the square d4
The coordinate system of the chessboard is standard, in view from the white player (whose pieces are at the bottom): the columns are noted from a to h (from left to right) and the rows from '1 ' to 8 (bottom to top).
Case (uppercase and lowercase) is ignored, but the majority of the time the moves are all written in lowercase.
How to note a promotion?
The writing of the starting and ending squares makes it possible to describe the vast majority of moves, with the exception of promotions, which involve a player's choice as to the promoted piece. In this case, the notation changes to 5 characters, the letter of the piece is added at the end.
The allowed letters are: Q for Queen, B for Bishop, N for Knight, and R for Rook.
Example: e7e8q for a pawn promotion to Queen
