Coding hyper-efficient chess programs has been something like a running contest among big time Smarty Pantses with too much time on their hands. For the last 33 years, the record for the smallest version of chess was held by the fabled 1K ZX Chess for the Sinclair ZX81. First published in 1982, 1K ZX had all of the basic chess rules and a opponent loaded into a now-hard-to-imagine 672 bytes of memory. Its publisher, David Horne , would go on to publish the code for the program in a three art Computer Magazine series (the first part of which you can see embedded below: This is the super-rad David Horne: 1K ZX's 33 year reign has just been challenged. The challenger is a program called BootChess, which includes all of the features of 1K ZX with a stunning memory allocation of only 512 bytes. The program was written by Olivier Poudade and Peter Ferrie . It was never a very graphic-intensive game, anyway This is a photo of Peter Ferrie: A photo of Olivier Po
