Piece Specific EPD's
Thanks to Mathias Gemuh, the author of BigLion and ChessGUI for creating a tool to sort the EPD's.
You have Piece specific EPD's. Moves starting with Bishop are saved in STS-Bishop.epd. Moves with Knight are saved in STS-Knight.epd and so on...
This helps in Piece Value tuning.
These files will be updated once the new STS is released.
Piece-EPD Tool is available for download.
