What is the algorithm for chess?

Answer 1

Algebraic Chess notation is the most widely used form of recording and expressing chess moves. For example: 1.e4 e5 2.f4 exf4 3.Nf3 d4...

N: Knight, K: King, Q: Queen, B: Bishop, R: Rook. Then there are the files A, B, C, D, E, F, G, H, hence a a pawn moving four squares on the e-file would e4. A pawn moving on the a-file two squares would be annotated as a2.

Descriptive chess notation is the less used format of recording and expressing moves, since it is less compact and more difficult to comprehend. At one time it was widely used, but was defeated by the algebraic system.

Example: 1. P-K4 PK4 Where the P stands for pawn and K for king,hence it can be translated as "pawn moves in front of king four squares. The last number in the annotation stands for the number of moves the pawn in front of the king moved.

This was the more complicated version and failed to catch on.
