Sally Simpson: Hi Jim,
" I would guess this is a clock simul, where Kasparov played maybe six good English players with a classical time control."
It was 10 board simul but with a difference.
First the scores.
Kasparov beat: Peter Wells, Neil Dickinson, Stuart Rachels (USA) and Teresa Needham.
He drew with Susan Walker - replaced by Gavin Crawley (see below), Ian Thomas, David Norwood and Phillip Rossiter
He lost to Stuart Conquest and Neil Bradbury.
The novel idea was not to have a normal simul with boards and pieces but use Acorn computers.
Each player sat in front of a screen and typed in his or her move.
Gary had White on the boards but the display on all screens showed Black at the top so the juniors had to play 'upside down'.
The colours displayed were white for the white pieces, purple for the black pieces, pale yellow for light squares and light green for the dark squares.
This is relevant because according to the players this display produced headaches. 'stars before their eyes' and general dizziness.
One player, Susan Walker actually fainted and had to be replaced by Gavin Crawley.
As the games wore on Kasparov's time became an issue as he had to type in the moves which takes longer than moving and pressing a clock. If he made an error typing in the clocks did not stop.
Nobody complained when he was awarded an extra 30 minutes.
