International Open won by Viktor Korchnoi

Viktor Korchnoi won about 25 International Open Chess Tournaments of grandmaster strength (others than official events also played in swiss system as an open, to avoid double-counting). 

Some players are in bold to facilitate the reading of all these names, it does not necessarily mean that they faced Korchnoi in the Open (swiss system), I tried to name always the next best players, but the selection of further listed participants rests subjective and a little sentimental 😉


1.  Lone Pine, CA, Open 1981 at age of 50!

🙂 Lugano got an extra-page, until now there was no other in the world wide web! 

The Lugano International Open from 1976 to 1989 (14 consecutive editions), could be considered in its international variety, age & gender mix and strength of participants surpassing London Lloyds Bank Open (1977 - 1994), Berlin Summer Open (1983 - 1998) and New York Open (1981 - 2000, no edition in 1982 and 1999) as the successor of Lone Pine and predecessor of the Gibraltar Tradewise Chess Festival, Qatar Masters or Moscow Aeroflot Open as strongest Open Festival of its time.
