Detailed Description

Definitions for game-independent moves.

Useful for games that can encode moves as positive integers (including 0). Negative integers are reserved for special meanings, like pass or null move and defined in this file. Don't make an assumption about the exact values of the special moves (apart that they are negative). If you do, at least document it with a static assertion. Classes that can work with moves of different games should only include this header.
