A moderately strong chess engine is included: Dreamer. However, should this engine be too weak for you, then you can use any other XBoard-compatible chess engine, including the popular Crafty and GNU Chess.
Other features include music, sound effects, on-screen move lists using SAN notation, undo functionality, and savegames in PGN format.
The DreamChess team currently consists of only a handful of people. We could use help in many areas, such as programming, graphics, sound and testing. If you’re interested in helping out, please send an email to feedback at dreamchess.org.
