Oh Donna is today's outstanding bet on a very tricky card at Ascot. Despite the paucity of runners, all the races have a competitive edge but Oh Donna could be someway ahead of her rating in the William Hill Bank Syndication Open Novices' Handicap Hurdle.

The handicapper has basically had to guess following the former pointer's debut win under Rules at Ludlow last month.

Tackling 15 rivals, Nicky Henderson's mare made short work of the opposition, leading three from home and being pushed out to beat Hot 'n Saucy three lengths.

Oh Donna has been given a mark of 100 but this highlyregarded individual ought to be able to progress some way beyond that.

Her main rivals are Vitaman, who reportedly may have disliked soft ground when pulled up at Uttoxeter on his penultimate start and My Shenandoah, who is a difficult ride despite having won his last two races.

Given that this stamina test should suit, Oh Donna is taken to put daylight between herself and the field.

Court Master is worth supporting each-way in the Bucktail Handicap Chase.

Super Coin is the "good thing" here, being 5lb lower than when winning at the course last Saturday but it may be dangerous to take his form too literally.

And while Court Master has been somewhat frustrating, this two mile trip seems to bring out the best in him.

Bob Buckler's 10-year-old tired over two miles five furlongs in heavy ground at Plumpton last time but could now surprise off his light weight.

The day's feature is the £25,000-added PML Lightning Novices' Chase, in which nearly all the runners can be given a serious chance.

Narrow preference is for Hurricane Lamp, who began to transfer his hurdling ability to the larger obstacles when beating Storm Damage five lengths at Ludlow.
