Really?! In Russian it means exactly the same! Czech and Russian sometimes are very similar.

Did you know that "Rybka" means "A Little Fish" in Czech?

I have heard nothing about Rybka, but my computer game is Chessmaster 10 and I think it is one of the strongest chessprogrammes in the world. Once I took two computers and held a game Chessmaster VS Fritz 8 (another popular American chessprogramme). I organized 4 games and the score was 2-2. I is interesting to note that White won only.

 

Computers are sometimes matched up by hardware specs, but mostly their ratings from playing other computers.  Most computer tournaments allow any hardware, since it is now the chess engine that is compared.  The -0.20 is the value of the position as determined by the computer engine.  The 18 is 18 ply (9 moves or 18 half moves) in their look ahead.  The 159 is seconds.  Most computers have special opening and endgame books.  There is an option to turn those books off.  I recently played Rybka (and Fritz and Toga) with two other masters, but the machines are too strong.  The games are here:

Two questions for anyone that knows or follows chess computer play:

1) When two computers play against each other, do they have to run on the same hardware specs? It doesn't seem fair that one runs on a 3GB super duper computer, and the other runs on an ibook?

2) What exactly does this mean? -0.20/18 159

I'm assuming -.20 means black is winning, what is the /18 ? and 159 i think is # of seconds.
