You can make your picks now Vik ! It's not done on a daily basis, the rules are that you pick your way through the draw before it starts. You attempt to predict all the winners of all the rd1 matches and then from those players you attempt to predict the ones who will get through to rd3 and then from those you attempt to predict the ones who will get through to rd4 and so on until you have an overall winner.
You do it all before the tournament starts and then wait and see how it pans out ! You could do it this morning if you have time. Once you've done your picks, email them to andymonium.
