Not exactly a "massive gamble" but on a quite Sunday afternoon, possibly of interest. 520 Newton Abbott. First price up this morning was 8/1, best price now 9/2. Pulled up on its last run 70 days ago, so somebody fancies it to run well against a strong looking favourite.
The favourite does look strong to me so I'm going 20 pts at 5/2 without Chilbury Hill.
