Digits to the right of it are multiplied by 10 raised to a negative power or exponent. The first position to the right of the separator indicates 10 −1 (0.1), the second position 10 −2 (0.01), and so on for each successive position. As an example, the number 2674 in a base-10 numeral system is: (2 × 10 3) + (6 × 10 2) + (7 × 10 1) + (4 ...
The general rule is that all moves and captures are made diagonally. All references to squares refer to the dark squares only. The main differences from English draughts are: the size of the board (10×10), pieces can also capture backward (not only forward), the long-range moving and capturing capability of kings known as flying, and the requirement that the maximum number of men be captured ...
Syzygy tablebases were developed by Ronald de Man and released in April 2013 in a form optimized for use by a chess program during search. This variety consists of two tables per endgame: a smaller WDL (win/draw/loss) table which contains knowledge of the 50-move rule, and a larger DTZ table (distance to zero ply, i.e., pawn move or capture).
Using between two hundred desktop computers at the peak of the project and around fifty later on, the team made 10 14 calculations to search from the initial position to a database of positions with at most ten pieces. [12] However, the solution is only for the initial position rather than for all 156 accepted random 3-move openings of ...
In the Portable Game Notation for chess games, FEN is used to define initial positions other than the standard one. [3] FEN does not provide sufficient information to decide whether a draw by threefold repetition may be legally claimed or a draw offer may be accepted; for that, a different format such as Extended Position Description is needed.

Mathematical tables are lists of numbers showing the results of a calculation with varying arguments.Trigonometric tables were used in ancient Greece and India for applications to astronomy and celestial navigation, and continued to be widely used until electronic calculators became cheap and plentiful in the 1970s, in order to simplify and drastically speed up computation.
The queen's position is the number of characters to the left of the "Q", giving 2 for the standard SP. The N5N configuration is obtained by omitting the "Q", giving -N-N- for the standard SP, so its N5N code is 5. In general idn = (bishop's code) + 16* (queen's position) + 96* (N5N code) For the standard SP, idn = 6 + 16*2 + 96*5 = 518
