RyanFish 1 x64 - The Accidental Stockfish Clone

RyanFish 1 x64 is a Stockfish 2.3.1 clone compiled by Velmarin from the github source of Ryan Takker. The executable banner showed that the author is Norbert Raymund which will confuse the tester. After the clone version was published, the github source URL of Ryanfish mysteriously disappeared.

Ryanfish scored 57.25% with 1053 wins, 676 losses and 871 draws in the gauntlet matches for the strongest computer chess engines. It placed #6 in the gauntlet and earned 3090 ELO rating points. Ryanfish is #5 in the Top 100 Chess Engines List edging ComStock 3 with 1 ELO point. There are now 3 Stockfish family in the top 6 which includes ComStock 3.  Stockfish has now 2 formidable allies to withstand the assault of the Ippolit clones that dominated the strongest chess engines list.

  1. Unlike ComStock, which supports RobboBases, RyanFish (also based on the obsolete Stockfish 2.3.1) looks redundant to me.

  2. Check out Komodo MP, dude, and let us know if it would be worth buying.
