Free chess engine with a tablebase So I've downloaded Stockfish and the Arena GUI, but I'm having trouble getting any tablebase I download to either load into Arena, or be compatible with Stockfish.  Any suggestions?  I'm willing to download a different GUI if it is easy to get a tablebase loaded.
If your GUI allows custom UCI options (I think you can do it in Arena, but check its documentation), you should be able to add a syzygy path yourself. Otherwise, you may try the popular Deep Fritz GUI. Check this link:
