ChessPDA 1.04 - ChessPDA is a full-featured chess database. ChessPDA allows you to enter games or chess problems (arbitrary positions) and replay them automatically or one move at a time. You may also take back moves, temporarily mark positions for analysis, revert to previously marked positions, and much more!  ChessPDA does legal move verification (legal verification can be turned off) and thus can be used by two players as an electronic chessboard. You may also replay library games or chess problems. Several games and problems are included in the online version and are automatically loaded. Send in the shareware fee to obtain a registered copy with the SAVE game feature enabled and including several 100-game and problem libraries.
