Tiger,
I would be more keen on EASYWORK for the RSA Chase than anything at the front of the market.
After a hurdles debut win over 2M from Mount Leinster (RPR 143 on hurdles debut) - Gordon Elliotts quote was:-
23Nov19 Gowran Park (16Hy, RPR 143)
He's a grand horse who loves that soft ground. I really fancied him in a winners' bumper last year but there were two fair horses that beat him on the day. He's a nice horse with plenty of improvement in him. He settled well. He's a chaser and anything he does this year will be a bonus for next year - Gordon Elliott, trainer of Easywork
A step up to 2M4F next time out brought that infamous thrashing of odds-on fav Unexcepted by 22 lengths, with an RPR of 153.
Straight into fav for the 2M Grade 1 Hurdle at the DRF after that, which was run on lightning fast ground on Day 1, over too short a trip, and a runner up place (RPR 146) behind easy winner Asterion Forlonge.
Final run in the Ballymore brought a step back up in trip to 2M5F and his best performance to date (RPR 155) when only Envoi Allen could lower his colours, with the Two Bigs well beaten into 3rd and 4th.
He is a 6yo Giggys gelding, so will be off chasing now, and his form over hurdles would rival that of Monkfish (RPR 154), Fury Road (RPR 152) and Latest Exhibition (RPR 152).
His two runs over 2M4F and 2M5F have brought much his best ratings (RPRs of 153 & 155), and for me, if Envoi Allen goes for the Marsh then Gordon will step Easywork up the extra 3F to the RSA this year, rather than having him take on EA at the Festival again. (not sure Giggys would want him taking on EA there again, either)
I think his price of 33/1 for the RSA is a big one, and he is my pick for the race at the prices at this point in time.
