Lay £9.76 on Mark Selby @ 1.59 = Potential liability of £5.75


Let’s have a look at our potential profit/loss for the possible outcomes…

Selby wins+ £5.33– £5.75£0.42 loss
Selby loses– £10.00+ £9.56£0.44 loss

So, no matter the outcome, we’ll lose a maximum of £0.44 in qualifying for our £5.00 free bet.

Free bet

Our £5.00 free bet will be credited by 12:00 on Thursday 25th February 2021 and will be valid until 09:00 on Friday 26th February 2021. Although the promotion page suggests using the free bet on Thursday’s matches, Betfred free bets can usually be used on any sports market.

Using straightforward matched betting, we should be able to convert our free bet into 80% cash, so £4.00. If we take into account our maximum qualifying loss of £0.44, this gives us a guaranteed profit of £3.56 on this Betfred offer!

* Mark Selby won the match 6-4, resulting in a profit of £3.58 on this Betfred offer. *
