Larry Kaufman

Larry Kaufman is a an American Chess Grandmaster. He is probably most famous for his work in computer chess programming. He has played both Shogi and Go recreationally.

A quotation from his book Chess Board Options:

I first learned shogi from a chess friend, Mark (he asked that I omit his last name), whom I met while living in South Florida where he then lived (later he lived in Paris for many years). He was not a very strong chess player, probably class A (1800 to 2000), but was a somewhat stronger Go player, and he taught me Go well enough to bring my level up from novice to shodan (maybe 1800 in chess terms). He had learned shogi from a British magazine by that name which was mostly translations of articles in Japanese magazines, and insisted on teaching me to play. I wasn’t very interested in learning, with the difficulty of the pieces being identified by Japanese Kanji which were meaningless to me, but after all the time he had devoted to teaching me Go I could hardly refuse
