Subject: [PATCH] Replacement for chess support This layout does not use
 lyxskak.sty, which depends on skak.sty Instead it uses chessboard.sty,
 depending on chessfss and xskak. Compiles and displays fine with pdflatex,
 XeTeX but still does not compile with lualatex. We are now able again to mark
 fields and moves on the chessboard
