What is the strongest chess playing computer program (chess engine)?
That seems to change from week to week, but the strongest engines include Rybka, Fritz, Junior, Shredder, Hiarcs, Chess Tiger, Zappa, and a few others, which are always surpassing one another with each new version. These are software applications that can be played on various systems, as opposed to dedicated chess supercomputers such as Hydra and Deep Blue. For more information, visit our Chess Software page.
