Maarten van 't Kruijs

Van 't Kruijs appears to have become affiliated with the United Amsterdam Chess Society sometime prior to 1851, when the club held the first Dutch chess 'championship' game.^[1] According to testimony from witnesses and other chess scholars of the time who were in attendance, Van 't Kruijs won rather handily in these tournaments. A few years later, a shuffle chess tournament was held in Amsterdam, which Van 't Kruijs also won. According to the long-running Dutch chess magazine of the time, Sissa, he had proven that shuffle chess was more emphatically expressed and that, “It is a field still undeveloped, to which labor we politely invite all our chess aficionados.”^[2]

On an 1861 visit to the Netherlands, the Prussian grandmaster Adolf Anderssen played a game against him and was so impressed by Van 't Kruijs' skill that he counted him among the ten strongest chess players in the world.^[3] It was around this time that he developed his prominent opening move and the one that would give him the most fame, that being the Van 't Kruijs Opening, 1.e3. One of the first times the opening was played was in 1863, in a game between Horing and Paulsen.

Van 't Kruijs continued to dominate Dutch chess, culminating in his victory at the 1878 Dutch Chess Championship.^[4] He then retired due to poor health.

Maarten Van 't Kruijs died on 30 March 1885 in Amsterdam. His eponymous opening continues to be played in various levels of chess, and his legacy jumpstarted Dutch chess. His theories were considered ahead of their time, though mostly considered part of Romantic chess.
