It was almost like the movie “Groundhog Day” as the university English teacher simultaneously played 20 chess matches, moving from one to the next, winning. Over and over again.

Although a couple of matches caused him to pause and linger, for the most part, he kept moving clockwise inside the rectangle of tables. He seemed to embody the theme of the 16th annual Art at the Capitol event: “Kālena, the Talent of Hawai‘i.”

Mind you, while his opponents were highly ranked in their own rights, they were probably less than a quarter his age.

At one point, onlookers filled most of the seats while others peered in through the open door. The live taiko drumming in the atrium from another event didn’t seem to distract Rubsamen, although he swayed a bit to the beat of the drums.

He moved quickly from board to board taking about five seconds before making a move. But this time, he stood in front of a board for about 15 seconds. (Kevin Fujii/Civil Beat/2025)

Rubsamen moved from board to board, taking about five seconds before making a move. At one point, he stood in front of a board for about 15 seconds. An eternity.

Trying to capture Rubsamen’s next move on camera was tricky. His hand flew as fast as a baseball player transferring the ball from mitt to throw.

One might not think of the game of chess as an art form like a painting or performing art. But the skill and strategy required to play one game, let alone 20, showcased Rubsamen’s talent. In addition to continuing to play at an elite level, he coaches scholastic-age players and members of the Hawaiʻi Chess Federation.
