THIS CRAZY WORLD OF CHESS by GM Larry Evans (page 100)

The matter did not stop there. The Soviet Union suddenly pulled out
two of her players from the Nineteenth Lone Pine Open in America after
learning Korchnoi was competing.

Either Larry Parr did not copy this correctly from Evans' book, or
Evans made a small mistake.There never was a "Nineteenth Lone Pine
Open." There were only 11, running annually 1971-1981 (see for
example: http://en.wikipedia.org/wiki/Lone_Pine_International). Evans
is correct that two Soviet players, Tseshkovsky and Romanishin, who
planned to play in 1979, did indeed pull out (or were ordered to pull
out) when it was learned that Korchnoi would play. That was the 9th
Lone Pine Open, so perhaps "nineteenth" is just an inadvertent typo.
At Lone Pine 1981, Korchnoi arrived only at the last minute,
catching the two Soviet GMs Yusupov and Romanishin by suprise. This
time they went ahead and played, and Korchnoi rubbed salt in their
wounds by winning the tournament.
