The games are 9x9. I don’t remember joining it, but I’m in it. https://www.littlegolem.net/jsp/tournament/tournament.jsp?trnid=go19.cv.GO9.49.3.1

It’s the Championship games for Go9x9, tournament 49. See the list here: Go championships Just click on the Size 9x9 #49 and you’ll see the links to the various leagues.

49.3.1 means championship 49, league 3, group 1.

My guess is that the naming scheme changed (from go.ch.48.x.x that it was before to go19.cv.GO9.49.x.x currently) due to the recent changes in ratings per game size and pages reorganization.

meant to write: 

  from go9.ch.48.x.x that it was before to go19.cv.GO9.49.x.x 

Seems odd for a 9x9 game to be labelled go19, even if it is also labelled GO9. I guess cv means championship in a variant, but it’s not as obvious as ch.

@Dvd I agree. Losing the 19, and using either  go.cv.GO9.49.x.x  or  go.ch.GO9.49.x.x would make it far more clear.
