Description given in 1999:
LambChop is a conventional chess program based around alpha beta searching and iterative deepening, plus the standard tricks such as hash tables, quiescence search, search extensions etc. LambChop can be grouped with those programs that use a combination of recursive nullmove pruning and full endpoint evaluation. Extensive use is made of square control and 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 NPS rate.
