In 1986, Abe participated in a special three-game match against Yoshiharu Habu called the ""Young Prodigy 3-game Clash" (天才少年激突三番勝負, Tensai Shōnen Gekitotsu Sanban Shōbu), which was a special project pitting the most promising young professional from Western Japan (the 17-year-old Abe) against the most promising young professional from Eastern Japan (the 15-year-old Habu). Even though Abe ended up losing the match, his play received high praise with professional Hirobumi Serizawa [ja] even stating that Abe was more talented than Habu.[2]
Abe's first shogi championship as a professional came in 1993 when he defeated Hiroki Nakata 3 games to 2 to win the 12th All Nihon Pro [ja].[2][4]
Abe's only appearance in a major title match to date came in 2002 when he challenged Habu for the 15th Ryūō title. Abe advanced to the title match by defeating his 12th All Nihon Pro opponent Nakata 2 games to 1 to win the best-of-three challenger playoff. In the title match against Habu, Abe lost the first two games before winning the next three to take a 3 games to 2 lead. Habu, however, went on to win Games 6 and 7 to defend his title.[5]
Abe became the 22nd professional to win 800 official games when he defeated Yasuaki Murayama in a 68th Ōza tournament preminary round game on January 30, 2020. He was awarded the "Shogi Honor Fighting-spirit Award [ja]" as a result, and become the first player to receive the award while still currently ranked 8-dan.[7]
Abe's only appearance in a major title match was in 2002 when he was the challenger for the Ryūō title.[9] Abe has won two non-major shogi championships during his career: the 12th All Nihon Pro [ja] (1993) and the 20th All Star Kachinuki-sen [ja] (1999–2000).[10]
