Nick de Firmian writes that 1.g3 "can, and usually does, transpose into almost any other opening in which White fianchettos his king's bishop".

"[4] The hypermodern player Richard Reti played 1.g3 several times at Baden-Baden in 1925, with mixed results.

1.g3 received renewed attention after Pal Benko used it to defeat Bobby Fischer and Mikhail Tal in the 1962 Candidates Tournament in Curaçao, part of the 1963 World Championship cycle.

The following lines are examples of the kinds of positions that can develop from the King's Fianchetto opening.

1.Na3: Durkin 1.a3: Anderssen 1.b3: Nimzowitsch-Larsen 1.Nc3: Dunst 1.c3: Saragossa 1.d3: Mieses 1.e3: Van 't Kruijs 1.Nf3: Zukertort 1.f3: Barnes 1.g3: Benko 1.Nh3: Amar 1.h3: Clemenz
