In 1982, Tze-Chung Chen won many titles, starting from Sapporo Tokyu Open. In many other tournaments, he had always acquired a position to compete for the championship. Soon after, he started his activity in the U.S. as well, and in 1983, he was given the Rookie of the Year title from the PGA TOUR in the U.S. In 1985, after he made a contract with ThreeBond, he won second place in the U.S. Open (Oakland Hills Country Club). At this time, Tze-Chung Chen became famous for the so-called “twice-hit chip”, but we must also remember his great achievements of winning the only double eagle in the history of the U.S. Open, as well as scoring a 65, tying the course record. He became second by a very narrow margin, but it was a moment when an Oriental player came the closest to winning the championship in a major tournament. In 1987, he won the Los Angeles Open as well as a total of six other tournaments in Japan. In 2014, he won the Kaohsiung Open (Taiwan PGA Tour) as the oldest player to win in a regular tour. In 2015, he won the Japanese senior golf tournament for the first time in its final match, Iwasaki Shiratsuyu Senior Golf Tournament. Currently, he aims to enter into senior tours in Japan. At the same time, he also makes efforts to nurture young golfers at the Taiwan PGA.In 2020, he won twice on the Taiwan PGA Tour (Southern Taiwan Senior Open Tournament, Oriental Sunshine TSPGA Open Tournament), and finished second twice (Friends of Yangde Changchun Invitational Tournament, Hsieh Min-Nan Golf Foundation—Cock and Chicken Invitational Tournament). Following these great achievements, he won 3rd place in the Rainbow Paint Changchun Open Tournament in 2023. He will continue to focus on developing young Taiwanese players at the Taiwan PGA, while challenging the Japan Senior Tour himself.
