How do I castle with ChessGenius?

To castle move your king two squares to the right or left. If castling is legal Chess Genius will accept the move and move your rook.
Castling is legal if the king and rook have not moved before in the game, the king is not in check and the squares that the king moves through are not attacked. For a better explanation and an excellent tutorial see

What is the rating of ChessGenius?

It is probably around 2600 USCF elo on a device with a 400Mhz Intel XScale processor.

What about Hash tables?

ChessGenius has user adjustable hash tables. The size can be set when a new game is started or from Tools / Options.
The hash tables can be adjusted in size from 64kb up to 16mb. ChessGenius plays stronger with bigger hash table, especially when ChessGenius has a long time to think. But big hash tables require more system resources.

Hash tables are used to store parts of the search tree. If ChessGenius encounters a position already in the hash table the result can be retrieved from the table thus saving search time.

How can I transfer a game from my WM device to my Desktop PC?
