Compensation, the inititiave, pawn structure, stamina, psychology, calculation, time-management, strategical out-playing, openings, variations, variations, variations - in short, all the usual stuff . . . ? Harald Borchgrevink won Blackpool 2007, and went for a rather different emphasis:
I enjoyed three cans of Tennent's on the way down, mostly to ease the pain of being inches away from Graeme Kafka's one working speaker, however a rather loud one, but at the board I would soon discover that I had the "flow" this weekend, so my slight fuzzy feeling should not worry me too much. With the black pieces I soon equalised, but my opponent played the middle game well, and as our pawn chains locked the centre efficiently, the a-file was my only hope.
Luckily, Nigel Chapman offered me a pint as we passed the first time control, and that did the trick. With my opponent spending much time, and me with no risk of losing, I managed to "grind her down", winning a pawn and then another before 0-1 was a fact. Not an impressive start, but nonetheless a point and a pint,
he wrote of round 1.
You can read the rest here, and I don't think it spoils anything to let you know the inevitable punch-line: "The trophy is now on display at the Sandy Bells pub."
Thanks to Tryfon Gavriel for the tip-off on this one.
