Well, in the end I did get to see Mark Hannon answering questions on Bobby Fischer on Mastermind tonight. Despite not having access to my own TV, I managed to watch via my computer using a TV tuner card. Isn't modern technology wonderful?
Mark Hannon did extremely well, scoring 13 points (and no passes) on his Bobby Fischer questions. I think he failed to get two of them - one, on the number of consecutive games Fischer won in the 1971 Candidates Matches - he said 20 when the answer was 13 (I think he misheard the question and added the games Fischer won at the back end of the Palma 1970 Interzonal). And he couldn't remember which piece Fischer had sacrificed against Spassky in one of the key 1972 match games (the answer was bishop and he said rook - for my part I cannot remember which game was being referred to). But 13 was a very good score under pressure (I think I got about 11 - under pressure of the glass of wine I had drunk shortly before). The questions were a good deal fairer than the last time chess featured on Mastermind. There were one or two tricky ones (where he had to remember the opening variation played in games) but he rose to the challenge.
But it was a case of "the operation was successful but the patient died." Mark piled up another 12 points on the general knowledge questions (some very tough questions in there) to score a very creditable 25 points overall. But another contestant just pipped him to first place, scoring 26. Never mind - the honour of chess was maintained.
