Monday, 16 July 2012: Timeform offer a runner-by-runner guide to a mile handicap at Ayr...

Dubai Dynamo is a tough handicapper who was back to winning ways at Ripon (1m) in May. In frame 4 times since, and excellent neck second over same C&D a week ago. Races off 2 lb lower mark now, and much respected.

Oriental Scot was back to best when winning at Haydock in May, and again suited by strong pace with narrow defeat over 9f at Musselburgh next time. Undone by further rise in weights at Windsor early this month.

Extraterrestial is a hold-up handicapper who is generally thereabouts but hard to win with. Not at best on last 2 outings, and his losing run now stands at 14. Percentage call remains to oppose.

Colour Guard was largely progressive in 4 starts at Southwell, winning 3 times at up to 1m. Creditable fourth of 7 at Ripon last month, but found nothing last time. Opposable.

Sam Nombulist opened his account in a visor at Doncaster (7f) in November, and improved to bag another big-field handicap at York last month, although had run of race. Well below form at Carlisle last time.

Paramour landed a 1m Pontefract maiden last August and bounced back to take 7f handicap at Newmarket last month. Well below form in 2 starts since, though, and now tried in cheekpieces.

Karaka Jack won big-field 7f handicap at York last July and at Doncaster on return in April. Back to form when third of 13 at Sandown last month, but failed to fire when mid-field at Carlisle last time.

Staff Sergeant produced a number of creditable efforts in defeat last year and improved to win over 9f at Musselburgh in May. Below form since, although more chance he can dominate here, and not ruled out entirely.

Dhaular Dhar was a surprise winner of big-field handicap at Doncaster (1žm) in October, and better effort this year when sixth of 11 at Chester (10.3f) last time. Left with plenty to do there, and may do better.

Indepub surpassed 2-y-o form when runner-up to Eastern Destiny in 9.8f Ripon handicap in May, and back to winning ways in 4-runner affair at Newcastle last time. Would have claims if securing early lead.

Timeform Verdict:

1. Dubai Dynamo

2. Indepub

3. Staff Sergeant

Timeform View: Dubai Dynamo can race off a 2 lb lower mark than when an excellent second at Ripon last time, and makes by far the most appeal. Indepub and Staff Sergeant can both go from the front, and would have claims if not cutting each other's throats.
