That is a depressing thought Puho, I am sure it won't happen, but if everyone has to take a clubs greenshot on both front and back then so be it.
I am very worried now as time goes by that our score is not going to be good enough. That is the nature of waiting I suppose, one always expects the worst.
My partner and I did several practice runs on our own just to get familiar with this format, so I hope that is/was allowed. We also had several hiccups during our attempts to play the round and as we had no screenshots were forced to restart.
Luckily in those aborted ( WGT ) rounds we had a loysy score going.
I had 2 power cuts and my partner lost his internet once, it really was a trial of strength for the both of us.
