I didn't stay for too long, but I did get to see one of the playoff games from the British Knockout Championship (another innovative event). Nigel Short was paired with Luke McShane and played a line against the Pirc which he said served him well against Yasser Seirawan about 25 years ago. Once Short played e6 McShane had to find the right defensive moves, but it was on move 12 that McShane played to wrong move. After that Short was always better, and won both the game and the playoff.
