Solving Losing Chess

Since late 2011 Mark Watkins worked on his long-term goal to weakly solve the game of Losing Chess, presumably by showing that 1. e3 wins for White. As of summer 2014 [4], leaving b6 and c5 as the remaining Black responses [5], 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 [6].
