I have gone moderate bet puissance de lune with sportsbet, if runs 2nd or 3rd get my money back.
I think it will be in first three, and there should be steady pace, which would suit a stayer, assuming it is up to the top level. I think it is.
If slow pace, and its a dundeel, is close enough, it will be hard to beat.
Blowout would be happy trails, so will have a small bet on it. It is a good horse with good form and has ideal barrier, although may get back.
With the 3yolds, you just neve know, although they seldom win.
good punting to you.
