Steve Bennett passed this to us recently via Paul Habershon. Its from a newspaper column citing a game played by Sandy Cordon at the Hitchin Congress in 1983. It was referenced on this website, shortly after Sandy’s death, when Paul mentioned that Jim Plaskett had called it stunning, and I agree. I will reproduce a snip of the column (slightly dodgy quality for added authenticity!) here and then publish the position properly with the solution in the New Year.
Not many of us get to play this sort of combination in a game of skittles, let alone a congress! It’s Sandy (White) to play and win.
Good luck – first correct answer wins a mince pie!
