Briareus was done by the extra half mile at kempton when 4th in the King George behind kauto. In truth he was one of those who threatened to lay up with him for a bit, before fading out of it. I still think he'd have beat Petit Robin if he hadn't come down in the Champion Chase as that one was tiring badly, yet Hendersons horse is half the price. My own suspicion is that 2 miles is too sharp, and 3 miles too far, so today is probably right his range. Admittedly he seems to perform better going right handed, but on a flat track with decent ground he's all but got his conditions today and 20's looks decent value to me. My suspicion is that he's got one big'un in him, and today looks as good a chance as he'll get.
Think Mirage Dore will place too at the longer trip over hurdles and would have won the Coral Cup with a bit more assistance from the saddle. The horse has been compensating for the jockey, but on a flatter track, on better ground, at a trip further (staying hurdles are normally quite slowly run) I suspect the combination that got him beat at Chelters might not be quite so potent today.
In fact an e/w double at 20's and 11's makes some appeal
