I think this would come under the heading of "Systems betting", I have been looking for occasions where I can make a book (using BEST odds available, from wherever) to at least 98%. Needless to say this is not easy but it does happen, I actually found 3 today 2 all in and 1 with deductions, (thankfully not applied) but still a bit worrying.

But my pont is that I have noticed that I can usually manage it in very small fields like 4-6. I actually had one today at 75% in a 5 horse field. an absolute gift!

It usually involves Betfair, and/or a begging phone call to one or more of the bookies that I bet with. but it is very satisfying when you get set.

Just wondering if any other systemites concentrate on smaller fields like this, it does seem to be an "angle"
