ETOBICOKE, Ontario &ndash; There are many questions to be answered in Sunday&rsquo;s $150,000 Plate Trial Stakes, a key prep for the June 26 Queen&rsquo;s Plate, but perhaps the most important ones involve two of the favorites: Can the speedy Bear&rsquo;s Chill stay the nine-furlong distance, and will the lightly raced Check Your Soul continue to improve?\r\nBear&rsquo;s Chill, a huge son of Artie Schiller, graduated second time out traveling seven furlongs Dec. 4. Trainer Reade Baker ran him once over the winter, which was a flat fourth-place finish in a 1 1/16-mile optional claimer on the grass at Gulfstream.\r\nBear&rsquo;s Chill ran similar spectacular races over seven furlongs in each of his two most recent outings, in a first-level allowance and the Queenston Stakes. On both occasions, he set a slow opening quarter and then picked up the pace before coasting home on top by a comfortable margin. He earned a 92 Beyer Speed Figure in the allowance and a 97 Beyer in the Queenston, numbers that make him the fastest member of this crop of Canadian-breds.\r\nBaker said he is uncertain about Bear&rsquo;s Chill&rsquo;s chances of staying the Trial distance.\r\n&ldquo;I just don&rsquo;t know,&rdquo; Baker said. &ldquo;His breeding says he&rsquo;ll go that far, and he&rsquo;s certainly built like a horse that will go that far, but none of those things are guarantees.&rdquo;\r\nBaker said Bear&rsquo;s Chill has retained his sharpness since the May 7 Queenston.\r\n&ldquo;He had a quick breeze and then we slowed him up a little the other day,&rdquo; Baker said. &ldquo;He&rsquo;s feeling great.&rdquo;\r\nCheck Your Soul graduated second time out, in a 1 1/16-mile maiden special on the grass April 15 at Keeneland. He ran greenly during a very wide trip in his first Polytrack try here May 1 in the Marine Stakes, but scored rather easily with just a 74 Beyer.\r\nTrainer Roger Attfield said he was content with Check Your Soul&rsquo;s performance in the 1 1/16-mile Marine.\r\n&ldquo;I don&rsquo;t think it was a stellar field, but he did it very nicely,&rdquo; Attfield said. &ldquo;He got a little bit warm in the post parade, and we&rsquo;ve been working on that. He&rsquo;s gotten better and better. He worked nicely [May 27]. Everything&rsquo;s on target. The farther, the better, for him.&rdquo;\r\nTrainer Todd Pletcher entered a promising maiden, Imhotep, and the stakes-winning sprinter Sensational Slam.\r\nBowman&rsquo;s Causeway, who was on the Triple Crown trail before coming up empty in the Grade 1 Florida Derby, is making his first start for trainer Chad Brown following a layoff.
