It's a elementary idea. The English linguistic communication opening, 1.c4, happens to opened upwards up a diagonal for the white queen (which I am using to stand upwards for HM Queen Elizabeth of England), in addition to hence I exhibit her exiting the board (representing the EU) on the next plow to an imaginary foursquare beyond the d1-a4 diagonal. Took me 10 minutes to knock it together in addition to set it on Twitter.
I'm unremarkably pleased if my picayune jokes larn one-half a dozen retweets in addition to a similar release of 'likes'. I intend I mightiness accept had every bit many every bit xx or thirty retweets on a proficient day. But, past times those minor standards, this ane proved positively viral - 675 retweets to date, in addition to 733 likes, without me doing anything to promote it (well, until this weblog post). It has been translated into other languages, in addition to had people disceptation over what the symbols stand upwards for (it has entered a wider, non-chess-literate sphere). Hat tip to Peter Doggers for prompting the idea. Still slightly gobsmacked that it struck such a chord amongst people.
