The Dutch Defense.
This was a strategic chess opening characterized by the move 1.d4 f5, aiming to control the e4 square and launch a vigorous kingside attack. Its origins trace back to the 19th century, with early contributions from Dutch players seeking to challenge the more classical e4 and d4 openings. The opening gained prominence in the early 20th century, especially through the games of Dutch grandmasters like Max Euwe, who became World Chess Champion. Well, at least that was what Wikipedia said. As for the truth, Sheva himself decided not to think about this matter too much, knowing that it wouldn't matter that much anyway.
Throughout history, the Dutch Defense had been favored by players who enjoy dynamic, asymmetrical positions and complex strategic battles, with notable practitioners including Bent Larsen and Hikaru Nakamura, who have employed it at top levels to surprise opponents.
