in this case it clearly is a backgammon timeout :)
i rarely timeout, so i dont know what a timeout does do for the match score in other game types
(i am trying to find the limits for my time control to cover my 3day-busy-reallife-weekens, and 3days to start seems ok, 10 days max seems ok, but 3 hours bonus per move seems too little compared with different timezones :))
