Субъект: Scoring of timeouts
Is it well understood how many points are awarded for a timeout in a cube match? In this game, I was trailing 4-2 in a 5-point match when my opponent disappeared. A backgammon is no longer possible on the board; in fact, if the game were played out, every possible sequence of rolls and moves would result in a gammon. I thus expected that when my opponent timed out I would receive 2 points for the gammon. Instead I received 3 points and won the match 5-4. I feel somewhat guilty for being credited with an impossible backgammon. Not very guilty, as I expect my opponent would also have timed out in the next game, but somewhat guilty.

I had thought that a timeout would be scored the same way as a resignation -- i.e. that the player who timed out would lose the maximum number of points possible from the final position, at the current value of the cube. But I can't find this written anywhere. Has anyone else had experience with this? Is this the intended result, or a bug?

KotDB: I've had time outs and received the max possible.

KotDB: Brainking assigns points based on the current state of the game when the timeout occurs. I think worst case scenario is not practical to calculate.

I'm pretty sure that the correct way to resign cube match game is to offer your resignation along with the number of points you are resigning. If you resign a single point to me but I think I can gammon you, then I reject your resignation and we keep playing. Brainking doesn't support this. If you resign you give up the number of points on the board.

This being the case, you should never resign a cube match game until you have borne off a least one checker, and then only after it is mathematically impossible for you to win.

jryden: I'm guessing that what you mean by the current state is equivalent to the worst-case scenario, except in a few unusual cases that I've just thought of (e.g. White has borne off 10 checkers and has 5 on his ace point, while Black has 14 on his ace point and 1 on his 19-point: a backgammon is not possible, but one might say the game is in a backgammonish state).

But the game in question was not in a backgammonish state, nor was a backgammon possible, yet I was awarded 3 points. Therefore BK behaves differently than the way you and I believed it behaved.

KotDB:  Seems odd, but the person who timed out doesn't have much basis for complaint.  You should not feel bad about it.

IMHO a player who times out in a multigame match should forfeit the match, not just the current game.

I agree with that, at least with backgammon cubed matches, which should really be seen as a whole and not as separated games. So if timing out is currently worth a backgammon, it is still a low price to pay.

As for resignations, it is true that ideally one should be able to state what type of game one should resign, but I don't find it too serious that one cannot. Proper autopass / autoplay would save a lot more time !

nabla: I disagree. There are many situations where one needs to play a dozen or so moves to avoid a gammon, where autopass would notb help at all. If one could resign "normal" without the need to move the dozen moves to avoid a gammon, that could potgentially reduce the time of a one-move-per day game by two weeks!!!

nabla: I think cubed matches are treated the same way as multi-game matches in other games. And there a time-out only times out a single game.

But I agree, it would be nice if you can offer a resignation for a certain amount of points. For the user interface, only three options need to be offered "resign with backgammon", "resign with gammon" and "resign". If a backgammon, or a gammon is not possible, those options don't need to be offered. And an opponents confirmation is only required if the choosen resignation isn't the highest possible.

Separately, it would be nice to have the option to resign the entire match - not just for backgammon, but for all games.

That would seem to be taking a rather defeatist position?  As Yogi Berra said, "The game's not over till it's over"

pgtnot always true I have resigned games when my opponent waits till the final moment to move. This because the games if left to run there cause would finish next decade, LOL:

skipinnz:  I know what you mean.  I am almost 66 years old, and wonder what will happen when I leave permanently!  There are a couple of games withe a couple of players which have already been running 2 years.   Is there a feature to advise permanent demise, or do one's games all have to time out when one shuffles off this mortal coil?   (It would serve some opponents right!)
