Should you want to know more about Nostradamus, please read here.
It plays decent chess, as an evidence I wanted to share this nice game, played vs Hegener&Glaser's Mephisto I, aka "Das Brikett", the famous 1980 chess computer. Its Computer Elo evaluation is 1.242 at active chess (30s/m) according to schach-computer.info rating list (equivalent to 1.323 FIDE Elo). Here it plays faster (level A2, 10s/m); using this level it is rated 1.248 CElo in my private list where all matches are played at 15s/m or 40/10 (moves/min). Nostradamus plays instantly (no tree-search). A win using dark pieces!
