Would have been an interesting amount lost at 1.01 on Jean van de Velde if Betfair was around for the 1999 Open


You're only laying the favourite if there's value to lay the favourite same with all trading/betting. If there's no value you find value elsewhere. How you calculate if there's value or not is up to you.
