Home * Engines * Pepito

Pepito,
a Chess Engine Communication Protocol and UCI compliant open source chess engine written by Carlos del Cacho in C, first released in September 2000 [1]. The recent version comes with an own GUI written in C++ using wxWidgets and can create opening book databases from a pile of thousands of chess games, applying advanced data structures such as B-trees and skip lists [2]. As bitboard engine, Pepito applies rotated bitboards with 1/2 MiB lookup tables, indexed by the full 8-bit line occupancy, to determine sliding piece attacks. Pepito played the CCT4, CCT5 and CCT6 tournaments.

Clones

The program Siboney by Francisco Rivera published in 2002 was based on Pepito with a changed evaluation [6] [7] [8]. In 2003, Deep<9> by pretended author Denis Grafen was proven a blatant clone of Pepito [9] [10] [11].
