Today on twitter it was posted that Djokovic was 4/1 to beat Cilic, so I went on skybet to have a look cos I thought that was cracking odds, anyway it was 8/1 on, so I didn't bother,but while looking at various odds, i noticed that Djokovic to get an ace in his first service game was 6/4, and for him NOT to get an ace in his first service game was also 6/4, so with even my limited mathematical knowledge, i realised it was a no lose bet, so lumped on the most i have ever bet. I phoned my son to tell him the good news, and by the time he tried to put it on, one of the odds(for him to get an ace) had changed to 2/1 on. Now, my question is ,does Skybet have to honour the bet, or can they welch on it, and if they do, will i get my money back?
