The Punt Acca: Charlie Huggins' three horse racing tips at Chepstow and Kempton on Friday

Opec (1.40 Chepstow)

Opec would be unbeaten over hurdles had she not fallen when well clear at the second-last at Market Rasen in June. James Owen's filly has made amends since, winning all three of her starts including when beating subsequent Fontwell and Cheltenham scorer Quantock Hills by three and three-quarter lengths. The fact she receives upwards of 2lb from all of her rivals is a bonus.

Martator (2.30 Kempton)

The form of Martator's latest victory suggests that he is more than capable of completing a six-timer here. The improving seven-year-old beat Kotmask by 11 lengths at Ascot last time and that runner-up has subsequently gone one better at the same venue, while the seventh-placed Frere D'Armes has also won his sole start since. Charlie Deutsch and Venetia Williams can combine for another big-race success as their representative receives 12lb and 9lb from chief market rivals Edwardstone and Boothill.

Galia Des Liteaux (2.50 Chepstow)

Galia Des Liteaux is back down to the same rating of 142 as when she finished runner-up in the Classic Chase and the winner of that Warwick marathon contest, My Silver Lining, franked the form when placing in the Grand National Trial and Midlands Grand National off higher marks. She is also rated 4lb lower than when eighth in last season's Grand National and Dan Skelton's mare will be suited by returning to this longer trip after finishing a respectable seventh over an inadequate 3m2f in the Coral Gold Cup.
