Ok - I think it's finally clicked. Please can someone look at my example below and tell me if I've actually "got" it....
I placed a £10 free bet on Skybet for Wolves to win tomorrow at odds of 2.05. If they win I get £10.50.
I placed a £3 lay bet on Wolves not to win on Betfair odds of 2.18. If they don't win, I get £6.54.
So if they don't win, the sky bet has cost me nothing, so I'm up £3.54 (£6.54 - £3 Betfair bet).
If they do win I have the £10.50 from Skybet - the £3 Betfair bet and - £3.54 liability which means I'm up £3.96.
I know there are better odds and matches to be doing this on, but it was suggested that I go and try it out so it finally clicked?!
Are you on the team profit newbies Facebook group? It's worth joining there, this is exactly the sort of thing to post there :) but I'll do my best here...
Did you lay the same outcome, same match etc? So you have backed wolves to win, and you need to lay against wolves to win - don't get confused as I nearly did and place your lay on the other team winning. So in your betfair it will say something like Wolves to win and underneath that the word lay - see attached where I lay the outcome of both teams to score - I.e. I was saying in betfair that I didn't think that would happen.
If you've done that...
If Wolves win, you'll get £10.50 minus £3.54 = £6.96
If Wolves lose or draw, you're up £6.54 minus nothing (as you used a free bet).
The Betfair stake side took me a bit to get used to. Essentially, your £3 stake doesn't mean anything once you've layed it. You're promising to honour somebody else's bet. So if we look at betfair and ignore sky for a moment, betfair will hold your liability in reserve (in this case, £3.54) until the score is known. When it is, you have either forfeited that £3.54 liability or not forfeited anything and gained £6.54.
At least, that's my understanding of it. Happy to be corrected if somebody else wants to weigh in!
Does that make sense?
