Exactly Sportsnut.
How would you feel, at the track, you've picked the first 7 winners, but not had a zac on any of them. Do you have a bet in the last??, or did you neck yourself after the 4th or 5th winner?

Butternut, to answer your question, against my better judgement (logic or tuition???) I would change my pick to the other box and apparently get the dosh 2 times out of 3.

Good 'on you Mark!
