Working on cycle 21 -- that's the one that culminated in the 2004 Tripoli KO -- prompted me to write The Worst World Championship Ever on my main blog. After I posted it, I started thinking that maybe it wasn't really the 'Worst World Championship Ever'. The aborted 1975 Fischer - Karpov match and the terminated 1984 Karpov - Kasparov match are two other strong choices, not to mention the nearly-abandoned 1993 Karpov - Timman match. I just realized that all three of those matches featured the same player. Now that's a coincidence!
