Tetsurō Itodani

Tetsurō Itodani is one of the more unusual figures in professional shogi, and the reason is easy to state: he is a titleholder who also studied philosophy at Osaka University. Those two things sound like they should pull in opposite directions. Shogi at the top level is popularly imagined as long silences and deep calculation; academic philosophy is slower still. Yet Itodani is known for playing remarkably fast — moves arriving at a clip that unsettles opponents used to the game's meditative rhythm. I suspect there is no contradiction there at all. What looks like speed is probably just an unusually high processing rate applied to positions everyone else has to grind through. He won the Ryūō, shogi's most prestigious title, and holds the rank of 9-dan, the top of the ladder. He also serves as an executive director of the Japan Shogi Association, which means he spends part of his life on governance rather than the board. Strong players rarely volunteer for administration. That he does says something about him beyond the wins.
