Computer Chess Created In 487 Bytes, Breaks 32-Year-Old Record
An anonymous reader writes: The record for smallest computer implementation of chess on any platform was held by 1K ZX Chess, which saw a release back in 1983 for the Sinclair ZX81. It uses just 672 bytes of memory, and includes most chess rules as well as a computer component to play against. The 32-year-old record has been beaten this week by the demoscene group Red Sector Inc. They have implemented a fully-playable version of chess called BootChess in just 487 bytes (readme file including source code).
I've noticed that they take a fairly liberal definition of "chess", as they simply discard certain rules, such as en passant pawn capture or castling moves, which are pretty important chess moves. It's a bit hard to argue that this is really "chess" if they just decide to leave out inconvenient rules ("chess lite?"). I probably wouldn't complain about other ommissions such as the 3-repetition rule, but castling?
Even so, a very cool accomplishment in micro-optimization techniques.
Irony: Agile development has too much intertia to be abandoned now.
Modern Chess is not now a variant called Mad Queen. It is a standardized game referred to as Chess and understood world-wide.
Modern chess may have originated in a game that at one time was referred to as "Mad Queen".
