All eyes will be on the excellent Holy Grail as he bids to make his return to Happy Valley tonight a winning one. Arguably the most talked about griffin of last year when he was produced late on by champion trainer Ivan Allan, he resumed this year over the longer sprint trip at the Valley and won. He has gone on since then to confirm his position as one of the rising stars of the local game and Holy Grail is expected to win this 1,650-metre fourth event for Classes One and Two. And it could be - if all goes well - a highly significant win for several reasons. Holy Grail was produced when Allan was coming under pressure last season from David Hayes and his scintillating debut win at Sha Tin was another vital success in his defence of the trainers' crown. Allan readily admitted at the time that had Hayes not just been inching closer, Holy Grail might well have been starting this season in Class Four. And what a good thing he would have been in that grade. Ironically, after a Sha Tin double on Saturday, it is now Allan who is closing on Hayes who remains hot favourite for the title but may just be finding that the reigning champion is getting a little too close for comfort. The Australian ace remains four winnners clear but if that was to be reduced to three tonight - and Holy Grail is a top chance for the Singaporean maestro - it would really get interesting over the final five meetings of the season. Allan was contemplating starting Holy Grail in the Sha Tin Vase but eventually bypassed that for this contest which does look within the gelding's scope. Holy Grail will be stepping up to the mile trip but his campaign this season has been carefully mapped out and he now tackles this distance at the best possible time. His runs have been carefully spaced and his breeding suggests that he will have no particular trouble running out the mile. On top of that, his early success this season shows that the tighter city track holds no fears for him. The manner in which former champion trainer Brian Kan Ping-chee's horses are running suggests that Winning Scene could well pose a threat to Holy Grail. Winning Scene has run several cracking races - not least the Derby - and has had just a minor let-up since his last run. Kan has been piling on the winners in recent weeks and his horses are jumping out of their skins despite many having endured arduous campaigns. If there is a secret to his success, it may well be that most of his horses simply do their work on the racetrack itself. They don't idle in their boxes and by racing them so frequently, trackwork is left to a minimum. Winning Scene certainly commands respect, but it may be that a combination of weight and work will prove too much for topweight Smart Kid. He has also had a fairly tough campaign and is being asked to haul 139 pounds. Deauville ran much better time under Malaysian rider Saimee but has no Valley form and could be opposed. That is not the case with Pinky Long Legs who returns to his favourite track after an abortive outing last time on the all-weather surface. With Douglas Whyte riding Holy Grail, claimer Patrick P. H. Tse has the ride on Danetop who is not hopeless. Basil Marcus is reunited with Strikers who ran a much better race last time under Danny Lee and is worth tierce consideration. Noble Dancer has had a magnficient season and cannot be ruled out although his more glittering efforts have been at Sha Tin. Gaylord also has good Valley form at the trip but it is more diffcult to make a case for City Patrol and Big Mac who is backing up after his recent crack at the Champions and Chater Cup.
