Likelihood functions for players' strengths in the fifth Interzonal tournament which occurred as part of the 1963 Chess world Championships in Stockholm, 1962.
(there are three chess datasets in the package, documented at

[the 1963 World championship], kka.Rd
[Karpov-Kasparov-Anand dataset], and chess.Rd
[rock-paper-scissors using Topalov-Anand-Karpov])
The 1963 World Chess Championship was notable for allegations of Soviet collusion. Specifically, Fischer publicly alleged that certain Soviet players had agreed in advance to draw all their games. The championship included an “interzonal” tournament in which 23 players competed in Stockholm; and a “Candidates” tournament in which 8 players competed in Curacao.
Likelihood functions interzonal
and interzonal_collusion
are created by files ‘inst/interzonal.Rmd’, which is heavily
documented and include some analysis. Object interzonal
includes
a term for drawing, (“draw
”), assumed to be the same for
all players; object interzonal_collusion
includes in addition to
draw
, a term for the drawing in Soviet-Soviet matches,
“coll
”.
Some other analysis is given in files
inst/curacao11962_threeplayers.R
and
