Played annually in Leiden or Noordwijk since 1936!

Quadrangular, later Open, mostly national or local colorit, sometimes expanded with elite players.

The 1965 edition of the Noteboom Memorial series presented a strong international invitation tournament with eight players
(see above).

The Leiden Chess Club in the Netherlands is the holder and the organiser of the longest running Memorial Tournament ever organised. Until 1978, the tournament was a round robin of four players (“Vierkampen”). Since 1979, the event is an Open (swiss system), six rounds played during a weekend. Reigning World Champion Max Euwe won the first Noteboom Memorial tournament in 1936, and again in 1949. 

Not to mix with an additional Jubilee tournament (also held as a Quadrangular) in 1970, played at Oegstgeest near Leiden
(see further below).

1938 Eliskases first above Keres, Pirc, Euwe, and Bogo. An excellent win for Erich Eliskases!

Noordwijk has been played <in June 1938>, the all-time famous AVRO has been played later that year, <in November 1938>, Eliskases was not invited, the retrospective chessmetrics rating by Sonas shows virtually, how close ranked Eliskases was: on position 9 of the world, well, AVRO invited 8 players, the 8 best of that time: http://chessmetrics.com/cm/CM2/Sing...

His career seemed aimed for the very top. But WWII stranded him, taking away the best years from Eliskases.

1965 (Noteboom Memorial) Botvinnik won ahead of Trifunovic as second and Flohr as third.

A cozy little invitation tournament, 6 players, only 5 rounds, very balanced.

The Tilburg chess tournament was a series of very strong chess tournaments held in Tilburg, Netherlands, a city in south-eastern Holland. It was established in 1977 and ran continuously through 1994 under the sponsorship of Interpolis, a dutch insurance company.

Fontys Hogescholen (University) shortly revived the supertournament series from 1996 to 1998, when the last edition had been played.

In total 21 tournaments (18 sponsored by Interpolis, among them the last three tournaments in knock-out modus, after a pause in 1995, the three final Fontys’ tournaments in round robin again).

Record winner: Karpov (7 wins, among them the first five in the years 1977, 79, 80, 82, and 83, but remember: neither Korchnoi nor Kasparov were invited / participated at Tilburg in all those years).

Gata Kamsky, still untitled (!) but already sole no. 8 in the Elo rating list II (July) 1990 before the Tilburg tournament started, tied for first alongside with Ivanchuk, ahead of Gelfand, Short, Timman, Andersson, Nikolic, and Seirawan, earning his third and final GM norm, just a few months after his 16th birthday. Kamsky thus gained his Grandmaster title without previously acquiring an IM title.

The winners Kamsky and Ivanchuk were celebrated in an amusing manner: Sixteen girls danced towards them and threw confetti.

Of course, Kamsky is the youngest winner of the series (at age of 16), the oldest winner is the usual suspect, Korchnoi (at age of 54).

No invitation for Korchnoi at Tilburg tournament series until the year 1985 to secure the soviet participation. Korchnoi won then at his first entry in 1985 (alongside with Miles, and Hübner), and was clear second to Kasparov in 1989.

Kasparov who had sensationally won Banja Luka in 1979 as untitled player, and Baku in 1980, made his personal debut at the summit level in the world's chess circuit at Tilburg in 1981 (Karpov did not take part this time, he avoided to play in international tournaments with rising Kasparov): 

Beliavsky won, meanwhile Kasparov only scored 50%, he suffered defeats against two former World Champions, Petrosian and Spassky, and lost to Timman as well. Hereafter, Garry would moderate his intuitive style towards better calculation and a brutal opening preparation, winning (or co-winning) in each international tournament he participated for incredible ten years in a row up to Linares in 1991 where he finished as runner-up behind Ivanchuk.

In 1997, Peter Svidler announced his entrance to elite with a fine win in a fearless game against Great Gazza. Svidler then was 21 years young, and had never met Kasparov over the board before. Finally, Svidler as best on tie-break, Kasparov, and Kramnik won that Tilburg Fontys tournament, followed by a triumph of Anand in the last Tilburg edition in 1998.

In total, 8 WCC played in the Tilburg series: Smyslov, Tal, Petrosian, Spassky (all not winning!), Karpov, Kasparov, Kramnik, and Anand.

Winners were Beliavsky (2x), Miles (2x), Korchnoi, Portisch, Ivanchuk, Gelfand, Svidler, Salov, Kamsky, Timman, Piket, Hübner, and Adams, plus the mentioned World Champions Karpov (7x), Kasparov (3x), Kramnik, and Anand.

Prominent players not winning: Larsen, Andersson, Ljubojevic, Polugaevsky, Hort, Short, Shirov, Leko, Topalov, or Judit Polgar, plus the mentioned four ex-WCC Smyslov, Tal, Petrosian, Spassky.
