Proscenium Arch and Bonheur are $13 chances in the Thousand Guineas Prelude at Caulfield on Saturday. Acting is a $21 chance in Group 2 race over 1400m. Proscenium Arch has raced on three occasions for a debut win at Sandown and two third placings. Bonhueur started her campaign with a ‘soft kill’ in maiden grade at Moe. The stable hopes the horse will improve from Tuesday's gallop.
