**Bionic Impakt**, 
a chess program based on [[Crafty]] by [[Hans Secelle]] and [[Albrecht Heeffer]]. As a strong chess player, Hans added a lot of knowledge incorporated from his former program [[Bionic]] in the [[Oracle|prescan routines]] and [[Evaluation|evaluation]] as well as the [[Opening Book|opening book]] and [[Time Management|time controls]] <ref>[[http://www.stmintz.com/ccc/index.php?id=40574|Bionic vs Crafty, once again]] by [[Đorđe Vidanović]], [[CCC]], January 23, 1999</ref>. There were no attempts to "hide" anything from Hans' and Albrecht's side <ref>[[http://www.stmintz.com/ccc/index.php?id=40771|Re: Bionic Vs Crafty Debate: some data required]] by [[Albrecht Heeffer]], [[CCC]], January 25, 1999</ref>, and despite violating the Crafty license, since program changes were never published <ref>[[http://groups.google.com/group/rec.games.chess.computer/msg/bb5b443496ea75fd|Re: Chess programming]] by [[Gian-Carlo Pascutto]], [[Computer Chess Forums|rgcc]], June 18, 2002</ref>, and lack of explicit permission by [[Robert Hyatt]] <ref>[[http://groups.google.com/group/rec.games.chess.computer/browse_frm/thread/f6b1901c0aa05a94#|Re: POOR BOB HYATT]] by [[Robert Hyatt]], [[Computer Chess Forums|rgcc]], February 21, 1999</ref>, Bionic Impakt was allowed by the [[CSVN]] to participate the [[DOCCC 1998]]. 

=DOCCC 1998=
While Bionic Impakt did quite well at the [[DOCCC 1998]] and caused an éclat after winning from [[The King]], [[Diep]] and [[Kallisto]] and finally becoming tied third, other participants complained <ref>[[http://www.stmintz.com/ccc/index.php?id=33849|Crafty vs Bionic Impakt, What's the difference Bob ?]] by [[Johan Havegheer]], [[CCC]], November, 24, 1998</ref> and raised forum discussions about using open source programs <ref>[[http://groups.google.com/group/rec.games.chess.computer/browse_frm/thread/ed89415506592e02#|Crafty implications ...]] by [[Chris Whittington]], [[Computer Chess Forums|rgcc]], March 4, 1999</ref> and [[Clones|cloning]] <ref>[[http://www.stmintz.com/ccc/index.php?id=40574|Bionic vs Crafty, once again]] by [[Đorđe Vidanović]], [[CCC]], January 23, 1999</ref>, also because during the two weekends of the tournament, the playing version appeared to have changed <ref>[[http://www.stmintz.com/ccc/index.php?id=34321|Re: Dutch CCC - Arthur on 300MHz G3 2nd weekend]] by [[Robert Hyatt]], [[CCC]], November 29, 1998</ref>, claiming some the program played the first weekend was more Crafty like <ref>[[http://www.stmintz.com/ccc/index.php?id=40708|Chess program similarity experiment]] by [[Bruce Moreland]], [[CCC]], January 24, 1999</ref>, but explicitly later denied by Heeffer <ref>[[http://www.stmintz.com/ccc/index.php?id=40771|Re: Bionic Vs Crafty Debate: some data required]] by [[Albrecht Heeffer]], [[CCC]], January 25, 1999</ref>. However, as a consequence Hans and Albrecht retired on Bionic Impakt and joined forces with [[Tom Vijlbrief]] on his program [[Ant]] <ref>[[http://www.open-aurec.com/wbforum/viewtopic.php?f=18&t=30320|Some news about H.
