Double or Bust or DOBBING as it is commonly known as is an in-Play trading method of laying at half the odds with double the money.
To demonstrate the method in simple terms lets suppose that a horse we fancy is 10/1 (11.00 in decimal odds) we are quite sure that it will do well but not convinced of its ability to win. To DOB this horse we would back it at 11.0 for £10.00 then at the exchange we would place a lay order at 5.5 (decimal odds) for £20.00. If when the horse is running in the race and the lay bet gets matched then we have a win win situation as follows
The horse wins: We win £100 from the bookmaker but lose £90 on the exchange making us £10 up and therefore doubling our stake.
The Horse doesnt win: We lose £10 to the bookmaker but win £20 on the exchange making us £10 up and therefore doubling our stake.
Sounds simple but the knack in dobbing is finding horses which will trade at at least half of its starting price. This involves a certain amount of research. To help with this I have a large stock of index cards and manually write down each runner of the day on a separate card with the following details added
