Sometimes money is taken on the exchange faster than you can place the bet, meaning that your bet is only partially matched.

Let’s say that you wanted to lay Minellahalfcentury (Wincanton 15:10) for £14.47 at odds of 3.85 and you place your bet, but there is only £2 in the exchange. £2 of your £14.47 lay is matched at 3.85, but now the odds are 4.00 and you still have £12.47 remaining that you need to get matched at odds of 3.85.

In this situation you have 2 options. Firstly you could leave it for a while and check back to see if the lay odds have dropped again and your bet has been taken. There is a risk involved here, because the lay odds may drift further, leaving you with no chance of getting the final £12.47 matched and you will then have to lay at much higher odds eating into your profits.

Secondly you can use the Tricky Bet Calculator to find out how much you should lay at the new odds of 4.0 to ensure that your matched bet remains equal. Watch the video below to see how we use the tricky bet calculator.
