The Punt Acca: Robbie Wilders' three horse racing tips on Saturday

Bond Chairman (3.00 Ascot)

This son of Kodiac saves his best for Ascot and has recorded his two best runs over this course and distance. Last season's Windsor Castle fourth was sent off a 40-1 shot on his return in the Palace of Holyroodhouse and ran a blinder when beaten a length into fourth. There should be more to come with that run behind and he is drawn in the same stall as the previous winner of this contest, Significantly, whose profile is not dissimilar to my selection's.

Isaac Shelby (3.15 Newmarket)

Charlie Appleby has landed the Superlative Stakes in three of the last four years with debut winners making their second start and it is no surprise the market has latched on to Victory Dance for the trainer. He didn't look as quick on his sole run as the previous three, though, and at a bigger price I'd rather side with Isaac Shelby, who produced a better Racing Post Rating and Topspeed figure than Victory Dance when hacking up on his first run. Better is expected now.

Samburu(3.50 Newmarket)

This son of Kingman was unbeaten going into Royal Ascot and enhanced his profile when finishing a close sixth in the Jersey Stakes. Running off a mark of 97 in the Bunbury Cup, Samburu is 8lb well in for that effort under Kieran O'Neill and retains a Group 2 entry at York next month. This could be the last time we see this progressive type in a handicap for a while.
