Here's how Aintree works:
If you backed a horse at Cheltenham, at a nice price and it let you down, back it again at Aintree.
If you backed a horse at Cheltenham and it won, and remains a nice price, then back it again.
It used to be profitable to focus on horses that had skipped Cheltenham. I don't have figures but that may have changed. Tom Segal certainly thinks so.
Favour Northern trainers in the handicaps.
Favour front runners on the Mildmay course.
Which leaves me pondering whether to forgive Rolling Star (I doubt it), and whether to back The New One at a very skinny price (probably). I'm on Anquetta ew at 20/1, shame Pricewise is also. And on Sixty Something ew also at 20/1, and will probably give Fago a go. Then I'll also play every race with a slew of other "festival" bets. See where we stand when the dust settles. Good luck.
Notes every Saturday on that day's racing and how well or badly I've done the previous week.
