"GERRY": I guess I don't understand what you are trying to say.

Are you saying you signed up for a brains tournament which was using a double cube, but you did not know it used the double cube? If that is what you are trying to say, then when you go to sign up for a tournament - there is a long description of all the options of the tournament above the area where you sign up at - so all the details (time, autopass, cube, etc...) should all be listed.

If it is not listed - then I agree that it needs to be.

If it is listed and you just did not notice it - then I don't think it would be the fault of the person who used a "cube" against you.

Which brings up the second question.

if you were going to win a game, and they use the cube - then you should not have lost unless you declined it and gave up... otherwise you may not have been in the best position to actually win the game.

..... Again - maybe I'm misunderstanding what you are trying to say - and if so, sorry. If you could explain a little better I would be happy to try to help.

***** Added - which tournament/games - might help to look to help understand what you are trying to say.
