Delfi is a Winboard/UCI chess engine written in Pascal designed by Italian chess programmer Fabio Cavicchio. It is designed to emulate a human playing style and is rated 2627 on the Chess Engines Grand Tournament.[1] The latest released version is 5.4.[as of?] Source code for version 5.1 is available.
From its release page, Delfi does not use bitboards like Crafty, but uses 16 × 16 array of bytes for board presentation. It uses capture history heuristic and smart thinking time allocation, from 50% to 400% of the average time. When some moves seem equal in its evaluation, it makes random moves.
