Understanding Chess Notation Types
Chess notation is the universal language of chess, allowing players worldwide to record, share, and analyze games. Our algebraic chess notation calculator supports all major notation formats, making it ideal for The Password Game, tournament records, and online chess study.
What is Algebraic Chess Notation?
Algebraic chess notation is the standard method for recording chess moves, officially adopted by FIDE (World Chess Federation) in 1980. This chess notation calculator uses algebraic notation as the primary format. Each square has a unique coordinate (a1-h8), and moves are written with piece letters (K=King, Q=Queen, R=Rook, B=Bishop, N=Knight) followed by the destination square. Examples: e4, Nf3, Qxd5.
Standard vs UCI Notation
Our chess algebraic notation calculator displays both SAN (Standard Algebraic Notation) and UCI (Universal Chess Interface) formats simultaneously. SAN is human-readable (Nf3), while UCI shows start and end squares (g1f3). This dual display is perfect for understanding how chess engines communicate.
| Piece | Symbol | Example (SAN) | Example (UCI) |
|---|---|---|---|
| King | K | Ke2 | e1e2 |
| Queen | Q | Qd4 | d1d4 |
| Rook | R | Rd1 | a1d1 |
| Bishop | B | Bc4 | f1c4 |
| Knight | N | Nf3 | g1f3 |
| Pawn | (none) | e4 | e2e4 |
Captures
Use "x" to indicate a capture: Bxe5 means Bishop captures on e5. For pawns: exd5.
Check & Checkmate
Add "+" for check (Qf7+) and "#" for checkmate (Qf7#).
Castling
Kingside castling: O-O. Queenside castling: O-O-O.

Square Names and Coordinates
Every square on the chess board has a unique name formed by combining its file (column letter a-h) and rank (row number 1-8). Files run vertically from left to right: a, b, c, d, e, f, g, h. Ranks run horizontally from bottom to top (White's view): 1, 2, 3, 4, 5, 6, 7, 8. Understanding this coordinate system is essential for using any chess notation calculator, especially when solving The Password Game puzzles.
Special Notation Symbols
Chess notation includes special symbols that provide additional information about moves. Our chess algebraic notation calculator helps you understand these annotations:
Move Symbols
x = captures+ = check# = checkmate=Q = promotion
Castling
O-O = kingsideO-O-O = queenside
(Use letter "O", not zero)
Annotations
! = good move? = mistake!! = brilliant?? = blunder
