−16
)Quote
Authors: Ben Dean-Kawamura, Georg v. Zimmermann (Germany) Released: 2003-11-10Links: Homepage, Jim Ablett's compile
This is Jim Ablett's optimized compile based on original Sunsetter C10. Jim fixed EGTB usage with 64-bit. Sometimes it fails to win simple endgames like KRPKP.
Issues with this engine: Frequent losses on time.
This is the only Sunsetter version we tested.
