GNU Chess is Free Software , licensed under the terms of the GNU General Public License , and is maintained by collaborating developers. It is often used in conjunction with a GUI program such as XBoard . In 1998 – 1999 GNU Chess underwent a transition to version 5. Version 5 was essentially a complete rewrite from scratch of GNU Chess to eliminate Spaghetti Code and replace antiquated data structures with more advanced computer chess implementation techniques. These included Bitboard s, a Search Algorithm called Principal Variation Search (PVS) (a variation by Professor Tony Marsland of Alpha-beta Minimax ), and full end-leaf evaluation. The primary author of version 5 was Chua Kong-Sian. {Link without Title} It uses a number of other techniques to improve its performance, such as an Opening Book (generated by studying master games) to help it start well and Hash Table s storing previously-analyzed positions to prevent wasting time re-analyzing already analyzed positions.
