I've written about Double or Nothing in play trading, or Dobbing,before, but that was over 18 months ago so many readers won't have seen the original article.

The reason I've returned to Dobbing today is that I've just read an interesting article in Betting Insiders that gave a secret but free source of selections for your trades.

So to recap here is the explanation of Dobbing that we shared previously, written by Dave Renham…

Dobbing is a term I came across a few years back – I am not sure where it originates from, but essentially a ‘DOB’ means ‘double or bust’. Essentially if we win, we double our original stake, if we lose we ‘bust’ or lose our stake. I am concentrating on the idea of dobbing by utilizing the in running betting markets. It may be easier to explain by giving you an example:

Let us imagine you back a horse pre race at 8.0 for £10; in order to create a potential DOB you try and lay at half the odds for double the stake – so a lay at 4.0 for £20.

If the horse hits 4.0 or lower in running, your lay bet will be matched and regardless of the result you will win £10 (less commission).

Here is the simple maths behind the two potential winning outcomes – if the horse goes onto win the race you get £70 returned from the ‘back’ part of the bet; you lose £60 on the ‘lay’ part of the bet giving you that £10 profit; if the horse does not go onto win, you lose your £10 stake from the ‘back’ bet, but gain £20 from the lay stake – again giving you a £10 profit. Of course if the lay part of the bet is not matched you will lose your £10.

Dobbing is well worth looking into and if you want to do it yourself basically you want to look for horses that you think will run prominently.

The easier profits probably come from bigger priced selections that you think will be up with the pace and on the National Hunt will jump well.

But you can also bet shorter ones that you think will win or go close.

For example if your fancy is 3/1 before the off then it needs to drop below even money for you to get your profit.

If you follow a tipster and you want to find out if it would be profitable to use their selections as Dobbing selections then you can research this by checking the Betfair results page and comparing the Betfair Starting Price with the In Play Low price.

Each time that the In Play Low is half what the Betfair SP is then that would have been a profitable trade.

If you are available during the day consider this as a way of making profit.
