Its difficult to overstate how big William Hills 7 places in the Supreme Novices Hurdle looks. Other books are 3, 4 and 5 places.
Looking at the race composition we can pretty much discount 5 horses who are over 100 on the exchange. We’re left with 11 contenders, 3 ins single figures. The book is running at a reasonable 133.8%.
If William Hill machines are taking stakes higher than £2 then don’t overthink this too much. Betting at Fixed Odds, Betting at SP, dutching the field, dutching at fixed odds, dutching at SP, dutching the top 11, blindly mugging any of the field each way, or blindly mugging any of the top 11 each way are all fine. Volume of money down will be directly related to profit.
