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 www.chesscorner.com

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.

ChessGenius for Windows mobile reads and writes standard PGN files. These can be read by almost all desktop chess programs.

PGN is "Portable Game Notation", a standard representation of chess game data in ASCII text files. It is used by most Chess software. For full details see: http://www.chessclub.com/help/PGN-spec. Here is a sample game:
