Sloppy Reading Tree [1]
Sloppy,
an open source chess engine by Ilari Pihlajisto, written in C to build executables to run under Windows, Linux and OS X, compliant with the Chess Engine Communication Protocol. Sloppy is released under the GPLv3 license, and was first published in October, 2007 [2].
Sloppy is full of low-level trickery with bitwise operators, efficient data structures and algorithms [3]. Starting with rotated bitboards [4],
it uses magic bitboards based on Pradu Kannan's implementation [5] to determine sliding piece attacks.
Sloppy 0.2.0, released in February 2008, supports Daniel Shawul's Scorpio Bitbases [6].
