Enter the optimal moves, in algebraic notation, for both white and black pieces.
The purpose of this game mode is to help you develop the ability to calculate long and correct
variations. By forcing you to think about both colors, you will also learn to view the board from
your opponent's perspective.
There is no easy way out: you cannot view the solution even after you make an incorrect
attempt. Your options are to solve the puzzle correctly, or to skip to the next puzzle.
You can try each puzzle as many times as you like.
All moves in this game mode must be entered using algebraic notation (sometimes called chess
notation). We offer a brief description of algebraic notation below, but if you are new to
algebraic notation, or you need a more thorough refresher, we recommend reading our
tutorial on how to read and write chess notation.
Algebraic Notation (AN) is a standard plain text format for recording chess games.
To enter a move, type piece + column + row. Columns are labelled a to h, rows 1 to 8, and pieces as follows:
