Its obviously based on an earlier version of ChessX. Basically it is ChessX with the ability to play games, do full game analysis and with an opening browser, the Hiarcs engine, and a few other features but without the dockable windows of ChessX, colored square and colored arrow annotations.
It is very very nice but then so is the current version of chessX and chessX at: www.box.com/chessX is free.
Is this going to be a worthwhile Chessbase alternative for Mac users? What do people think?
