 * Home * Engines * Delicate Brute**

an experimental chess program by Don Beal written in C, which participated at the ACM 1991 and the WCCC 1992, running on a Sun-4 [|workstation] and about 4K Nodes per second in 1991, and at the WMCCC on a Sun Sparc II with about 10K Nps. Apparently, Delicate Brute used selective search features as introduced by Don Beal, such as using the null move in quiescence search.
