As last year (if I remember correctly) they are offering a free bet to the same stakes if you pick the winner of the King George.
I think King King is a perfectly fair price at 6-4. I was considering backing it until I read in the Racing Post this special offer.
My new strategy is to back the horse at 6-4 (10 pts max bet.) and lay back on Betfair at 2.64 so you are even if Kicking King wins. This way, I will effectly be paying a small premium (approx. 1 pt) for an approx. 40% chance of a 10 pts max bet on the 1.10 @ Huntingdon tomorrrow.
