the problem is that in the temporary file, there is not an absolute path and the chess-game files are not copied into the tmp directory.
Indeed. So the bug is in our InsetExternal template "Chess". This is now http://bugzilla.lyx.org/show_bug.cgi?id=5320
Besides that, at my place LyX can't find chess.layout / lyxskak.sty / lyxchess.sty, but that might be something with my installation.
You need to install the class file manually to your TeX system. I do this automatically in my installer, unfortunately this is not the case in Joost's Windows installer. (For Linux and Mac I don't know if this can be done automatically when installing LyX.)
thanks and regards Uwe
