Controversy
IPPOLIT was initially prohibited from many computer chess websites after the author of the chess engine Rybka claimed it to be a clone of his program.{{cite web|url=http://chessprogramming.wikispaces.com/Ippolit|title=chessprogramming|website=Chessprogramming.wikispaces.com|accessdate=2016-09-25|archive-date=2016-10-02|archive-url=https://web.archive.org/web/20161002223327/http://chessprogramming.wikispaces.com/Ippolit|url-status=dead}} IPPOLIT authors have denied the accusation. Even today, some chess rating lists still refuse to include it in their lists of tested programs.
