=Tournament Play=
Gandalf started its tournament career at the [[WMCCC 1993]] and caused a stir while winning versus [[MChess]] and [[Quest]], but also had its tactical blackouts of a highly [[Selectivity|selective]] search with only one [[Ply|ply]] [[Brute-Force|brute-force]]. It further played the [[WCCC 1995]], the [[WMCCC 1995]], and becoming a more conventional program in 1996, the [[WMCCC 1996]], [[WMCCC 1997]] and [[WMCCC 2001]]. Dan operated Gandalf almost at all [[IPCCC|IPCCCs]] from [[IPCCC 1994|1994]] until [[IPCCC 2007|2007]], one time runner up in [[IPCCC 2005 b|2005]] and several times third. Gandalf played various [[Aegon Tournaments]], [[Dutch Open Computer Chess Championship]], [[International CSVN Tournament]] as well as [[CCT Tournaments]].

given from the [[ICGA]] tournament page <ref>[https://www.game-ai-forum.org/icga-tournaments/program.php?id=7 Gandalf's ICGA Tournaments]</ref> :
==1995==
Gandalf is a PC program developed over the last ten years. The program performs highly selective searches, combining a one-ply brute-force search with selective search and [[Extensions|search extensions]]. The search does not use standard techniques like the [[Null Move Pruning|null-move method]], but instead uses a rule-based method involving a calculation for every [[Node|node]] to decide which moves are good. Development of the program was an extremely difficult and time consuming task. Gandalf searches about 1500 [[Nodes per Second|nodes per second]] on a [[x86|486/66]]. Gandalf has considerable [[Knowledge|chess knowledge]] and plays aggressively, which is unusual for a highly selective search program. Gandalf uses an opening book containing about 500,000 positions.
==1997==
Gandalf was born an extreme selective program (1 ply brute-force + selective search) doing 1500 Nodes / sec on a [[x86|P90]]. On [[SSDF]] you see a rating of approx 2050. To compete, Gandalf got a standard null-move search engine in early 1996 and has done well at both [[WMCCC 1996|Jakarta]] (6/9) and [[Aegon 1997|Aegon97]] (TPR 2391). It has a high amount of chess knowledge, many extensions and is only doing 30K nodes/sec on a [https://en.wikipedia.org/wiki/Pentium_Pro PP200]. Gandalf searches approx to depth 9-10 in the middlegame on a PP200.
