WEEKEND PREVIEWS:PACEMAKERS have won the Queen Elizabeth II Stakes in the past but it won't be just that fact that will concentrate attention on Honoured Guest at Ascot today, writes Brian O'Connor

Aidan O'Brien's runner is set for pacemaking duties in aid of his illustrious stable companion Henrythenavigator who attempts to win a fifth Group One of the season in this afternoon's feature.

Colm O'Donoghue will team up with Honoured Guest, just as he rode Red Rock Canyon in that controversial Juddmonte International last month, but he will be hoping his role provokes no British Horseracing Authority fireworks this time.

Instead Murtagh on the Ballydoyle number one as well as connections of Tamayuz and Raven's Pass will be keeping in mind how two pacemakers - Maroof (1994) and Summoner (2001) have managed to steal this prestigious prize from the front.

Murtagh and O'Brien will also be represented in the Group Two Royal Lodge Stakes with Indian Ocean who is backed up by Set Sail.

Today's Group Three feature at home is Gowran Park's Denny Cordell Lavarack Lanwades Stud Stakes which has attracted the 113 rated Carribean Sunset but which may end up providing a welcome change of luck for She's Our Mark.

Pat Flynn's mare is already a winner in this grade but looked very unlucky in this race last year when a hampered fifth behind Timarwa. Fortune wasn't kind to her either in the Galway Mile last July while the Champion Stakes at Leopardstown earlier this month looked too ambitious.

She's rated to run equal to Carribean Sunset today and with a clear run She's Our Mark could be a value bet to overcome that Group One performer.

Oh Goodness Me ran into the Park Stakes contender Baliyana on her last start at Leopardstown but her experience could be crucial in today's mile maiden while Grand Opera represents the in-form Grand National winning trainer Gordon Elliott in the last race and can make the wait worthwhile.

Navan hosts an all-National Hunt card which features the €25,000 La Grande Chase and it looks like providing Oodachee with a suitable winning opportunity.

This two and a half miles should be ideal for a horse that was capable of chasing home the handicap "good thing" Oslot in the Galway Plate during at the summer festival.

Noel Meade always does well at his local course and Rinroe is an interesting contender for the Beginners Chase.

The six-year-old had smart bumper form and looks to have the scope to do well over fences.
