During last year's Commonwealth Championship in Honk Kong the Novag Super-Constellation computer proved so successful at devouring Fide titled players in blitz games (5 minutes for each player) that it was spontaneously dubbed the 'Blitz Monster'. The 1985 Commonwealth , Championship, again sponsored by Novag, is currently in prog- ress at the London Docklands Museum on the Isle of Dogs. Instead of entering a commercially available Super-Con, Novag has put in two experimental machines, `Monster X' and 'Monster Y', which indi- cate the shape of things to come in Novag chess computer developments. 'Monster Y' already displayed were-mechanical ten- dencies in round 1 when it viciously sav- aged A. J. Stebbings, rated at 2210. There- after, its next two opponents came armed with silver bullets, though International Master Danny King experienced some horror in round 2 when the trigger tempor- arily jammed. Unfortunately, 'Monster X' has not yet managed a successful trans- formation and is in no danger at all of winning the £10,000 prize put up by Legal and General for any player who scores 11 out of 11. In fact, after three rounds only Chandler, Watson and Bellin still have a chance of carrying off the booty. Here are two exciting games from early rounds, both featuring John Nunn.

At this point Black offered a draw which White unwisely declined. 17 Rd Bxc3 18 Rxe3 Nxe4 White never seems to obtain sufficient attacking equivalent for the loss of this central pawn. 19 Rh3 d5 20 f5 Qd6 21 Bd3 Ne5 22 Bbl Rc6 23 fxg6 fxg6 24 RxfB+ KxfS 25 Bel h5 26 Bxe4 dxe4 27 Qe2 Rcl 28 Rc3 Ral 29 Qe3

The hot news this week is that Fide President Florencio Campomanes called off the Moscow world championship match `without decision'. My detailed comments on this unprecedented measure appear earlier in this week's Spectator, as well as comments on initial steps to host the projected rematch in London later this year in September.
