Hopefully the final release :-)
At startup SlowChess now calculates the estimated strength on the hardware it is actually running, that means the maximum ELO level is the estimated strength of the unleashed SlowChess. If you use very slow hardware and the engine startup takes too much time, let me know. There are no changes in the chessplaying parts, if you run a tournament there is no need to update.

Is based on SlowChess 2.96 by Jonathan Kreuzer: http://www.3dkingdoms.com/chess/slow.htm
Many thanks to Jonathan Kreuzer for sharing his wonderful engine and the clear and easy to understand source code.
UCI_ELO feature: It is possible to set ELO values between 1200 and the maximum strength on your hardware. They are very good tuned compared to the old SSDF values which are supposed to be very close to the human values. Thousands of testgames where played against emulations of dedicated computers between ELO 1400 and 2400, please take also a look at Results.txt.
Chess960: Chess960 should work as Winboard and as UCI engine under ChessGUI, Arena, Shredder and Fritz, as Winboard Engine under Winboard. Under ChessGUI chose the AHah_KxR option. As Winboard Engine you can set the hash size in megabytes from the command line: SlowChess2960.exe -H48. Supported values are 6, 12, 24(default), 48, 96, 192. Anything in between is set to the closest lower value.
The evaluation is exactly the same as the original version except of a modification of the castling evaluation in Chess960, and I am happy that I didn’t slow it down, in fact the new version is even slightly faster because of a few simplifications.
SlowChess2.960 is completely bugfree. If something is going wrong it is your own fault or a it is a bug of the UI. Feel free to contact me if you want to prove me wrong.
