I was phoned at my house one night to go along to Sandy Bells
and stop a riot over a row about the En Passant rule.
I had to carefully explain to this brute of man what the player did was legal.
DO NOT PLAY EN PASSANT IN A PUB AGAINST A STRANGER!
Remember that post from about 10 years ago when both players
thought it was checkmate (it had been with a pawn and it was not
checkmate because the mated played could play PxP en passant.)
We tried dropping hints but both players thought one had checkmated the other.
They blamed the RHP computer and things started getting nasty when they were
told to study the rules of chess.
Then a MOD happened along to tell us to stop discussing a game in progress.
After your 30 minutes you are booted out to make room
so other luckless punters can get their 30 minutes worth.
This way Agon can sell 300 or 450 tickets at £55.00 a pop
to keep re-filling a hall that holds 150 seats. It's a masterpiece.
In Berlin in 1914 Capablanca beat Lasker 6½-3.½ in a rapid-transit match,
(something akin to blitz or 5 minute chess) one of the games (as yet no score)
produced a position so interesting that the two of them tweaked it a bit and
together composed that study. That is the position on the Cuban 1988 stamp.
