both players usually say something like “have a good game” when the game

starts

which is sometimes shortened to “gg” in online Go

@gennan

when the game finishes they usually say something like “thank you for the game”

@gennan

“well played” (regardles if you won or lost)

in other words: “that game was good”
which also possible to shorten to “gg”
