There is a lot of people who just miss their turns to be kicked out when they dont like their teammates or the situation on the warfield...
I think that if they are doing it often they should be banned - trashed - thrown out - killed - get additional penalty points taken of the points what do theyr hawe them - anything - whatewer...
The point is: you do hawe a parter in the game of doubles and he or she dont like you or the way your are playing or the situation on the board is bad and so they just leave you alone ant they desert from the battle. We all depend on eachother in the games of doubles or triplets and no one stands a chance when he is fighting alone against two or three players united against you.
When the things are going bad the partners, team mates, brathers in arms should stick together and unite the forces and not that one of them just leave the battlefield...
Man.... my English is teribble - I hope you will get the point of this...
