[Kirk]

Which free GUI do you prefer and why?
Arena is maybe the most famous but it exists a lot of other that I don't know very well.

Here is an overview:

For online play: Winboard/Xboard

For engine/engine contests and Epd analysis: Arena

For openings study and game preparation: Scid

I also like Jose, but it is not as good at database operations as Scid and the engine operations are inferior to both. However, I think it has the best *looking* GUI. So maybe it wins the beauty award.

I think I would probably like ChessAssistant Light best of all:

Except that I already have the full-on commercial version so I don't use the light version.

I have never tried JOSE. How are the engine operations inferior?

thanks
