As requested by Bull, a quick guide to matching the Gee Gee's (How I do it at least). Beware that it is much more volatile and has complexities such as rule 4. Personally I don't worry about rule 4 as it can work for you as well as against you. I have lost £7 on a qualifier that should have been pennies, I've also returned an extra £6 on a SNR bet. It tends to even itself out BUT don't do this if you can't accept losing more than you thought you would
The bigger the meeting or race, the greater the competition between the bookies and more liquidity on Betfair. At 11 am most races on betfair have between 2 - 20,000 matched, for ascot this was more like £250,000.
At the off there is usually £300,00 - 600,00 and again for ascot more like £3-4m. This made ascot great for arbs and I made >90% on EVERY SNR I did and on some >100%
When the bookies publish their early prices get on quickly and look for an arb. Glancing Betfair you'll soon realise which of the days meetings will attract the money. You can normally find a least 1 arb or narb and often 3 or 4 races will have an arb in them. Get your bet and lay in place as with any other sport.
