Houdini 2.0c 64-bit (3123+15
−15
)Quote
Author: Robert Houdart (Belgium) Link: Homepage
Information: There is some concern in the chess community that some versions of Houdini may contain substantial parts of Stockfish code. These concerns have not been tested in a court of law, or reviewed by court-appointed independent experts. Includes both SSE and non-SSE games. We found little if any difference in our testing. Includes games from 2.0 and 2.0c
This is one of the 19 Houdini versions we tested: Compare them!
