On the subject of laying bets; it's something I've not done a lot of, although when I have I've generally been successful. My mind struggles to see value in that regard as it would when backing for something - I don't know what because, as mid-table says, you're basically betting on something not happening.
It never really crossed my mind to lay Hamilton yesterday because I was close to certain that they would win, although not certain enough to bet at 1/3 or suchlike.
