Toledo, a family of minimalistic open source chess programs by Óscar Toledo Gutiérrez. Toledo Chess 1 with text-mode user interface is written in C, and won the 18th International Obfuscated C Code Contest (IOCCC) 2005 in the Game category. Toledo Chess 2 even has an own X-Window and Windows graphical user interface and won the 19th IOCCC. Further, Toledo Nanochess, written in C as well, occupies only 1274 non-blank characters, while Toledo Picochess fits in 1K of source, but without en passant, castling or minor promotion. Toledo Javascript is the Nanochess JavaScript version, 2258 bytes, and Toledo Java the Java port. In January 2015, Óscar Toledo G. released Toledo Atomchess, a chess program of only 481 bytes of x86 machine code.
