I thought I'd check out the May 1983 BCM. it has a picture from the Varsity Match on the cover. See below (and yes on page 199 they have the colours wrong on the Ivell - Regan game.)

The coincidence being myself and Ian Mullen have an article inside the same magazine on the Edinburgh -London match and just a few days ago I was asked about it on chessgames.com.
Also coincidental...No Russians at Wijk ann Zee in 1983...Balashov, Psakhis and Tal were not allowed to play because Korchnoi was playing.
There is a mini review (page 208 ) of a book called: 'Queens Gambit' by Walter Tevis. It mentions a few technical inaccuracies adding the definitive novel on chess has yet to be written.
