'''Ananse''',<br/>
a chess program by [[Walter Bannerman]], which played various [[World Microcomputer Chess Championship|World Microcomputer Chess Championships]], [[IPCCC|International Paderborn Computer Chess Championships]] and four consecutive [[Aegon Tournaments]] from [[Aegon 1993|1993]] to [[Aegon 1996|1996]].
While Ananse did quite well against humans, in computer tournaments it often suffered from [[Engine Testing#bugs|bugs]], also due to premature, not well enough tested program changes between rounds, once even running Ananse under a [[Debugging|debugger]] with breakpoints enabled ([[WMCCC 1995]]). Competing programmers, who seemed obligated to win with their programs, often got nervous when Ananse played a good book line and [[Opening|opening]], for instance during the [[WMCCC 1996]] in [https://en.wikipedia.org/wiki/Jakarta Jakarta], [[Frans Morsch]] in the game of Ananse versus [[Fritz]].
=Description=
given in 1997 from the [[ICGA]] site <ref>[https://www.game-ai-forum.org/icga-tournaments/program.php?id=30 Ananse's ICGA Tournaments]</ref> :
200K code, 62K data. Basic alpha-beta search with several special routines providing a 'human touch'. Plays very much like a human player, even in the middle game. Search depth : 6 to 15 ply. No hash tables.
Best tournament results : 2 and a half points at [[Aegon 1993]] and 2 points at [[Aegon 1994]], plus several misses in [[WMCCC 1996|Jakarta '96]] (due to bugs) and a good game against Fritz 4. The current version is the best ever. Many improvements with the help of participants in Geneva the last 2 human tournaments in Geneva, where Ananse was the only participating program.
