free bet advice......

its people like you joining the betting gang without any real knowledge of what you are getting into that pay my billsare you under 25 by any chance

£50 on Villa to beat Fulham with Coral @2.30

Lay Villa here @2.34 , backers stake £28

Villa win and you get £65 back from Coral , lose the £38 or so liability on Betfair

Villa don't win then you'd be about £27 green after commission on here.

Either way you make £27 profit .

You want to back something at Corals at long odds (10+, the longer the better really, as long as you have the money at Betfair to cover a lay bet at similar odds), but where the odds at Corals aren't much worse than on here. Then if you wish, lay the same bet on here to secure a profit. You should be able to get close to £50 (£40 at the very least). For it to work you obviously need a decent chunk of money on here.

I used to be in his shoes... nothing wrong with learning the ropes (although the more you can work out on your own the better you will understand it).

1 - To make maximum value from a free bet you want to use the free bet to back something at as long a price as possible (since you never get the stake back you want to maximise possible payout).
2 - To guarantee maximum value from a free bet you want to lay it on betfair for the minimum price possible (almost always this will be higher than the bookies price).

Both 1 and 2 are important and need to be taken into account together and you will need a lot of cash in your betfair account to cover your liability if laying at long odds. 

Another example similar to tobermory, which requires over £500 in your betfair account:
£50 on Norwich to beat Arsenal with Coral @11 (which is like 12 in betfair prices)
Lay Norwich here @15, backers stake £36.79
Norwich win and you get £550 back from Coral, lose £515.06 liability on Betfair = £34.94
Norwich don't win and you get £36.79*0.95 = £34.95

Either way you make £34.95

Right now you can back Barcelona 4 - 1 @ 19 at Corals, and lay the same selection @ 19 on here. That would be a decent choice.

If you've got the cash in Betfair, back Furyk each way for the Masters @ 80/1.  Lay £22.50 on the win at 90 and £27.50 on the place at 14.5.  You'll win around £120 if he placed or £50 if he isn't.
