Rybka Wins In Leiden
Some computer chess tournaments aim to determine the best chess program by running all the engines on the same hardware to create a level playing field.
The Open Dutch Computer Championships in Leiden, now in its 30th year, dispenses with such limitations for a no-holds barred smack-down between the top engines.
The most jaw-dropping hardware this year was the mind blowing 800 cores monster powering Jonny.
Twenty 'players' competed in a nine round Swiss competition and the winner was top seed Rybka with a near perfect 8.5/9 score, way ahead of the rest. Only Spark escaped with a draw against the 'little fish'.
Since Rybka was created by IM Vasik Rajlich (pictured), it has dominated the computer chess world and become the engine that sets the standard for others to beat.
The Rybka 4 engine is available in both Aquarium and Chessbase GUIs.
