Dilworth variation #1
You don't need to be a superstar to receive immortality in the game - all you need is the ability to hitch your name to a popular opening system. One classic case was English amateur correspondence player and humble railway's clerk Vernon Dilworth (1916-2004), who published analysis in the British magazine "Chess" during the early 1940s that rehabilitated an old line of the Open Lopez. Dilworth became famous overnight after his analysis was spotted by the great Mikhail Botvinnik, who used the tricky line (1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Nxe4 6.d4 b5 7.Bb3 d5 8.dxe5 Be6 9.c3 Bc5 10.Bc2 0-0 11.Nbd2 Nxf2!?) as a surprise weapon against Vassily Smylsov during the 1943/4 Moscow Championship. And the 'Dangerous Dilworth' is not only tricky but still alive and kicking today with many titled players over the years falling victim to it.
