Bet 365 have the Chelsea vs Stoke result to be Stoke or Draw priced at 2.00 Betfair offer you a lay of Chelsea at 1.73
I am still trying to work out the ins and outs of this kind of thing but would I be correct in saying you get £37 more value (ignoring commision) from Betfair if it was to win as the backer wold have to put up £137 to win my £100 whilst if I backed it with Bet 365 I'd only leave with £200 rather than £237?
