The fourth Max Euwe Memorial Chess Tournament was organized by the Verenigde Spaarbank in Rotterdam, the Netherlands from May 10th to the 17th, 1990. Following the format of previous editions of the memorial, four of the world's top grandmasters were invited to play in the double round robin event. As before, adjourned games were completed on the rest days occuring after the third and fifth rounds, and the time control for the tournament was forty moves in two hours followed by an additional hour for each twenty moves after that. This year's line-up included three Euwe memorial veterans and one new addition. The participants were (in order of ELO): Dutch grandmaster and previous Euwe memorial champion Jan Timman (2680); Soviet grandmaster Mikhail Gurevich (2645); British grandmaster and winner of the 2nd Euwe memorial Nigel Short (2630); and Swiss grandmaster and inaugural memorial participant Viktor Korchnoi (2625). The average of the combined ratings of the players ranked this event as a category XVI tournament. The move to Rotterdam was hoped to capitalize on the world cup tournament in the city last year, but it was ultimately deemed fruitless and the Euwe memorial would be moved back to Amsterdam the following year. Gurevich came to win the event, but Korchnoi edged him out by winning their fourth round encounter in a significant position in the Dutch Leningrad. Korchnoi won clear first having gone undefeated with Gurevich trailing second just half a point behind in the final. The final standings and crosstable are as follows:

1 Korchnoi 4/6 ** ½1 ½½ 1½

2 Gurevich 3.5/6 ½0 ** 1½ ½1

3 Timman 3/6 ½½ 0½ ** ½1

4 Short 1.5/6 0½ ½0 ½0 **
