We rapidly then improved Echec and the version 1.5 finished second of the [[WMCCC 1990=|1990 World Microcomputer Chess Championship]]. Echec even should have win the tournament since it had a winning position against [[Mephisto Lyon|Mephisto]] but since our new program [[Cumulus]] was having visibly a bad bug and that we were not sure that the Bug was not in common code shared by Echec, we were happy with a draw and set the [[Contempt Factor|contempt factor]] to +4. When [[Richard Lang]] saw that, he set Mephisto's Contempt Factor to -2, laughing. Well of course, we were all thinking that Mephisto should win... Mephisto took a poisoned pawn and then came into a losing position. Echec tried to [[Repetitions|repeat the position]], and Mephisto did not want at first but its score went bellow -2 and finally the programs drew !
