John Oxx admits it is very much a discovery mission when What Style takes to the track for only the second time in the Leopardstown 1,000 Guineas Trial on Sunday.

The daughter of Teofilo created a favourable impression when beating the experienced Snow Queen on her debut over this course and distance in August.

While she was not seen again, the Aidan O'Brien-trained Snow Queen had four more races and will again be in opposition.

"What Style is going all right and has just had the one run which she won so she's an unknown quantity," said the Currabeg trainer.

"It's a good race with a good-level standard of fillies with good ratings and a bit of experience behind them so she's up against it.

"We've no idea what her level will be eventually. She's just had that one run and we haven't worked her too hard. She doesn't require a lot of homework so we'll have to run her a couple of times to see where she fits in.

"She's got a bad draw too, on the outside (nine), which isn't great, but we'll just have to see. I won't be making any predictions where she's going to finish. We'll have to play it all by ear.

"The filly she beat last year, Snow Queen, seemed to have improved and ended up better than she looked at that time."

Snow Queen's rider Joseph O'Brien, son of the trainer, expects the Danehill Dancer filly to run a decent race.

"She's in good form and she's a filly with plenty of ability, but she has her quirks," he said.

"She won a good race over six furlongs on her last run last year and I don't see any reason why she wouldn't stay a mile.

"She has form on softer ground, so hopefully she'll run a nice race."

Bunairgead got off the mark at the third attempt over this seven furlongs and her trainer Jim Bolger gave an upbeat report on the New Approach filly.

"She won her maiden well and seems to have improved, so we're hoping for a good run from her," said the Coolcullen handler.
