Deletion of Karosel 2D

Comment: Although the article is written by the developer, that doesn't necessarily make it |OR or |not-notable; it is, however, a |COI which raises those possibilities. I also disagree with the notion that bidding systems don't belong here. What is necessary is that it is POV, V and OR|NPOV, V, and NOR. On that, I am undecided; it has been published in American Contract Bridge League's ''Bridge Bulletin'' and on the "Bridge Guys" website but the article is not written clearly enough for me to understand and it is not well-enough referenced to |reliable sources to dispel POV, V, and OR concerns. Happening upon the article, I tagged it as lacking some necessities and made a request for help from Wikipedia talk:WikiProject Contract bridge|WikiProject Contract bridge. They seem divided as to whether it is notable but one editor promised to do a clean-up in the future
