Dabbaba is a program written by Jens Baek
Nielsen from Denmark. The program is a fully functional program, and the
author does not ask you to send him money for using his program (so, while
he keeps the copyrights on his program, use for personal purposes is free.)
Dabbaba is a program that plays chess against you. Additionally, it
can also play several chess variants.
The graphics and interface of the program
fulfill their purposes, but are not very fancy. Nice points of
Dabbaba are not only its price (as it is free), but also its options, like
the chess variants it plays.
The chess variants, played by Dabbaba are:
Stationary Chess. The king cannot move; castling is forbidden.
Knightmate Chess. The knights are replaced
with kings, and the king is replaced with a knight. The goal is to mate
the knight; there is no castling.
Chancellor Chess. The queen has the combined moves of rook and knight.
This is called Almost Chess by original inventor
of this chess variant Ralph Betza.
Archbishop Chess (Janus Chess). The queen has the combined moves of
bishop and knight.
Nightrider Chess. Knights are nightriders: they can continue to make
knight moves in one turn when going in the same direction, but may capture
only after the last standard knight move.
Some variants where knights have additional possibilities: these are
types of Augmented Knights, as in Betza's
Chess Variant.
Grid chess.
Rooksquare chess.
Pawnfreeze chess.
Dabbaba has played 8 games against two Danish players both with a danish
rating of 2000. It was at the level 'game in 15 minutes'; Dabbaba only got 8
minutes giving the operator time to transfer the moves.
Dabbaba ran on a Pentium II 233 Mhz and won 5-3 (4-4 had been more fair).
