How to connect the Syzygy Bases to Stockfish with Syzygy Bases support in Winboard 4.7.3a? I tried to do it in the GUI and Winbord and link to them the way in winboard.ini, but it does not work. Maybe it's impossible?

I think that the WinBoard option -egtFormats "syzygy:PATHNAME" should make the engines aware where they can find the syzygy EGT. (I recall Polyglot does support the standard UCI option for syzygy-bases under this name, but I am not 100% sure.) You can also type syzygy:PATHNAME in the 'EGT Path' field of the Common Engine Options dialog. If a UCI engine uses an option for the syzygy path that is not recognized by Polyglot, it should appear in the Engine Settings dialog, and you can set it from there. (If you want to set it automatically on loading the engine, you can install the engine with the 'extra WinBoard option' -firstOptions "OPTIONNAME=VALUE".)

Thank you! I added the path to the database in winboard.ini and it's now working (";syzygy:D:\SBases_345")! It seems that the polyglot don't support the way in database!
