(This time I've spelt 'moment' right!)
We go back to the year 1964 and the World Students Olympiad.
G.Dahlin (Sweden) - K.B. Richardson (England)
and this position appreared...
and White sealed his next move.
A little while later Dahlin got in touch with Richardson and said:
"Let's do some analysis, Although I'm two pawns up I don't think I can win this."
So with nothing to lose Black agreed and watched as White displayed some
poor endgame technique and failed to find a win.
"It's a draw." said White: "Do you want a draw?"
"Yes." agreed a happy Black and went off to tell his mates.
After the result had been posted WHite's sealed move was revealed.
Despite this amazing piece of gamesmanship England won the match.
Sweden 1½ : 2½ England
Broström ½ - ½ Hollis
Westman ½ - ½ Rumens
Dahlin ½ - ½ Richardson
Pihlgren 0 - 1 Wood
