Douglas Bryson has a nice little item for chess trivia fans in his column in the Sunday Scotsman. An Erwin Knopfler played in several Scottish championships in the early 50's. He turns out to be the father of musicians David and Mark of the band Dire Straits, as confirmed by David. Bryson may have had this tidbit cut for space, but I remember David Knopfler's active participation on the World team in the famous "Kasparov versus the World" event in 1999. I was on the other side of course :-)
[Update: Changed the link to a longer version of the article on the Chess Scotland webpage. This one mentions the Kasparov vs the World connection.]
