Hello Dear Friends,
I have run a new testing-played by Fruit 2.0 vs Engines (released around 2004 year)
Some Notes (if we test the engines without books):
http://www.sedatcanbaz.com/chess/scct-no-books/1)Fruit 2.0 test (no books):
*Fruit 2.0 and Zappa 1.0 (when Zappa is with Black pieces) have similarities in openings
*Fruit 2.0 vs Fruit 2.0, both same versions have identical opening playing style
*The rest engine openings are almost different than Fruit 2.0 opening playing style
Games:
http://www.sedatcanbaz.com/chess/games/Fruit20test.rar2)SCCT SSE/Non-SSE test (no books):
*There are some similarities in openings, played by the Top chess engines:
- Houdini / Strelka / Komodo / Rybka / Ivanhoe / Critter / Stockfish
http://www.sedatcanbaz.com/chess/scct-sse-no-sse/3)SCCT 3 Type Tournament (no books):
*Some engines (Rybka;Glaurung;Thinker;Bright;Toga;Loop...) have similarities in openings too
http://www.sedatcanbaz.com/chess/sccts-3-type-tournaments/More Details:
*It seems many of the above engines are based on similar opening-related code
*These testings are done mainly for different purposes (not for proving which engine is a clone)
*Once more we noticed that many chess engines are each other relative
*Mostly of the played openings are far away from the current strong opening theory
Best Wishes,
Sedat Canbaz
