it makes perfect sense, it only from the surface looks like idiotic situation ... tell me, please, would you rather play 6 hours with a very good players, knowing that you are going to lose, or play 2 minutes and give up ? this is just funny illustration .... but seriously, good player is going to win with you anyway so do not sit to the game
using a doubling cube with this sort of players.
If this is going to be within a tournament, well, you have no choice, you have to accept and fight, and miracles happen, this is your only hope ... when you accept you lose 2 points, if not, you lose 1 point ... you will only shorten your pain by refusing ... another question ? what do you expect
from the player, who doubles the stakes after the first move ? If you know this player personaly, he will not do this, for what ? If you play on-line, you just accept and play . I was playing backgammon many times with doubling cube used right away ... but I wasn't the one who offered it . For me, this abusive use of doubling cube, can happen anywhere with any sort of game ... this is a matter of ethics rather than sportsmanship ...
