In my most recent game, Arena to 3 points, I was 2-0 up after game one and well ahead in game two that was a Crawford Game for a single point (no doubling allowed).
I’d borne off one piece. My opponent had one piece on the bar. They forfeited and I gained a backgammon for three points, taking the match 5-0.
How does BGA determine a forfeit gammon/backgammon? Was it because I had borne off the single piece? Had the opponent forfeited a turn earlier (still on the bar) but with me not having borne off, would the forfeit have been for a single point? (I would have accepted as I only needed one more point for the match).
I’ve read a little and it seems etiquette would be for the player forfeiting to set their terms, so forfeit for the game stake (one point, unless doubling happened) or forfeit for a gammon/backgammon. The opponent can reject a ‘too low’ forfeit, but counteroffer that the forfeit be for a gammon/backgammon. It looks like BGA determined the forfeit was for a backgammon. Possibly three forfeit buttons might help, or the opponent can counteroffer the forfeit. And yes, discuss the forfeit offer via chat.
Further etiquette in match play would be to accept a lower forfeit value if it concludes the match. In my case I would have accepted a one point forfeit as that was all I needed for the match. It’s poor etiquette to hold out for the gammon/backgammon “just so” they can win with that achievement. Winning a 3 point match by 5-0 is the same as 3-0; the match is won, which is all that matters.
