'''Mark James Watkins''',<br/>
an American mathematician affiliated with the School of Mathematics and Statistics <ref>[http://www.maths.usyd.edu.au/ School of Mathematics and Statistics, University of Sydney]</ref>, [https://en.wikipedia.org/wiki/University_of_Sydney University of Sydney], and member of its ''Computational Algebra Group'' <ref>[http://magma.maths.usyd.edu.au/group/ Computational Algebra Group]</ref>. In [[Computer Chess Forums|computer chess forums]], Mark Watkins is well known under the pseudonym "BB+" as an expert poster and publisher of recognized papers concerning the [[Rybka]] [[Rybka Controversy|controversies]] (both [[Ippolit]] and then [[Fruit]]). In February 2011, Mark Watkins disbanded his anonymity when involved in the [[ICGA Investigations]] regarding Fruit and Rybka.

=Solving Losing Chess=
Since late 2011 [[Mark Watkins]] worked on his long-term goal to [https://en.wikipedia.org/wiki/Solved_game#Weak weakly solve] the game of [[Losing Chess]], presumably by showing that 1. e3 wins for White. As of summer 2014 <ref>[[Mark Watkins]] ('''2014'''). ''Solved Openings in Losing Chess''. [[ICGA Journal#37_2|ICGA Journal, Vol. 37, No. 2]]</ref>, leaving b6 and c5 as the remaining Black responses <ref>[http://www.jsbeasley.co.uk/losinge3e6.htm Losing Chess 1 e3 e6] by [[John Beasley]], August 2014</ref>, all other responses to 1.e3 are indeed White wins, along with earlier work done by [[Ben Nye]] and others, as demonstrated by [[Proof-Number Search]] combined with [[Endgame Tablebases]]. On February 02, 2015, 1. e3 c5 was announced solved, on October 10, 2016, 1. e3 b6, proving 1.e3 wins <ref>[http://www.open-chess.org/viewtopic.php?f=3&t=3023 Losing Chess: 1. e3 wins] by [[Mark Watkins|BB+]], [[Computer Chess Forums|OpenChess Forum]], October 10, 2016</ref>.
