I have been using Betfair to lay ALL horses that I can that are under 2/1, stopping when I'm in front. A nice tax-free income. Haven't laid any runners o/s because I don't have access to the calls so don't know what the results are like. I am looking forward to laying runners for the place on the Grand National tomorrow night, even though they pay 1-2-3-4, last year only 4 runners finished the course out of 40 something.
