I can't be sure of the relevant dates at the time, so the following could be wrong, but IIRC Run For Oscar was during a period when the BHA routinely gave Irish horses hefty hikes if required to assess them solely on Irish form.
To get round this, Byrnes brought Run For Oscar to Haydock and, although he won by a comfortable four, got a mark for the Cesarewitch perhaps ironically lower than if he hadn't made the August scouting expedition and had stayed at home and maybe won a similar race in Ireland instead.
And, as you say, he bolted in at Newmarket.
The Reverend Hubert (who I also bet last year) has a different profile but I thought he won very easily over course and distance in the trial, the time was decent imo, the ground will be similar and, while the trainer is an often-discussed apparent law unto himself, even with a penalty, and at the revised weights, I see no reason why he shouldn't: 1 Be off for his life and 2 Go a lot closer this year than he did last year.
But I respect the chance of Belgravian and I could easily end up dutching the pair, or at least not losing on the latter.
pawras wonders why many of us talk so much about races like this.
Talk doesn't equate to turnover - I'd imagine most of us bet on legion races a week, but we only talk at length about traditional big events like this in which many of us share a common interest.
