Nesik participated in the 3rd Polish Computer Chess Championship and took: 2nd place in uniform hardware category and 3rd in the open category - more information.

From this site you can download a new Polish chess engine. It is currently under heavy development, and I hope that each time you visit this page in fututre there will be a newer, stronger and less buggy version ready for download. I am sorry to offer only a Win32 version at the moment - a portable, multi-platform release is planned.

About the author: my name is Marek Strejczek. I'm an MSc in Electronics and BSc in Computer Science (graduated respectively 2004 and 2006 from Technical University of Lodz, Poland). I used to be an active chess player (current FIDE rating 2138, status: inactive).

At the moment Nesik offers:

Winboard interface
alpha-beta function
aspiration window search
iterative deepening
bitboard and rotated bitboards move generation
static exchange evaluation
quiescence search
transposition table
killer moves
history heuristics
null move
some (fractional) extensions
pondering
evaluation function (considerable chess knowledge, but not tuned yet - poor in endings)
opening book (about 200,000 positions)

Remark:

Nesik is no longer developed or maintained. Still, if you encounter a problem using it please drop me an e-mail - I might be able to help.
