An ability to handle testing ground will be vital at Pontefract and course specialist Penny Pot Lane falls into that category.
Richard Whitaker's mare holds few secrets from the handicapper these days as a seven-year-old - but having been second the last twice, she is clearly not far from a winning mark.
The last time she was successful came off 65 last September at Ripon and while she has gone eight starts without a win, now off a mark of 66, her turn is surely not far away.
She has two wins at Pontefract to her name and always seems to run well at the track.
Farhan can make his experience count as he switches back to the turf in the racingtv.com/British Stallion Studs EBF Novice Stakes.
John Butler's colt has run well three times at Wolverhampton, without necessarily relishing the sharper test on that all-weather track.
On his second of four career starts at York, he was a fair fifth and again ran as if this stiffer course and extra distance can only be in his favour.
Michael Stoute's Hydros looks good in the Injured Jockeys Fund Maiden Stakes. The Frankel colt, a half-brother to Royal Ascot winner Sangarius, is clearly worth persevering with.
