=Description=
from the [[ICGA]] tournament site <ref>[https://www.game-ai-forum.org/icga-tournaments/program.php?id=90 LambChop's ICGA Tournaments]</ref>
LambChop is a conventional chess program based around [[Alpha-Beta|alpha beta]] searching and [[Iterative Deepening|iterative deepening]], plus the standard tricks such as [[Transposition Table|hash tables]], [[Quiescence Search|quiescence search]], search [[Extensions|extensions]] etc. LambChop can be grouped with those programs that use a combination of [[Recursion|recursive]] [[Null Move Pruning|nullmove pruning]] and full endpoint [[Evaluation|evaluation]]. Extensive use is made of [[Square Control|square control]] and [[Mobility|mobility]] throughout the program which contributes to an active playing style. The overall design philosophy is focused on the accurate processing of each node as opposed to emphasizing a high [[Nodes per Second|NPS]] rate.
