With just one longshot in races that made up the Rainbow 6 on Sunday at Gulfstream Park, there was no single winning ticket and the carryover going into Thursday&rsquo;s card is a whopping $2,288,394.In order for someone to have a single winning ticket, there has to be more than one longshot to win. With moderate field sizes in most of the races that make up the sequence, that is not likely to happen Thursday. There is rain forecast for the Miami area all week, though, so anything is possible.Here is a look at Thursday&rsquo;s Rainbow 6 races.Race 4: Country Strong, who will be a short price to win the one&#45;mile $10,000 maiden claimer for fillies and mares, will likely be singled in small tickets. Kaufy Futures could pull off an upset for trainer Tamar Levy, though. She is lightly raced and could take a big step forward in her second try at a one&#45;turn mile.Race 5: Notorious Nick and Ten Carat Daddy should be part of any ticket if this one&#45;mile maiden special weight race stays on turf. A longshot with a chance is Primo Post, who comes out of a hot barn and will be running with blinkers for the first time. Undaunted rates a serious look, especially if the race is moved to the main track. Race 6: Oh Danny Bear stands out in this $25,000 conditioned claimer for 3&#45;year&#45;olds and up. He is going for his fourth&#45;straight win and coming off a victory in a similar race in his first start off the claim by trainer Marcus Vitali. He has never raced on an off track, though. Rayo My King and So Nifty become more interesting if it comes up wet.Race 7: The Rohan Crichton&#45;trained Rachel&rsquo;s Smokin is the deserving 2&#45;1 morning&#45;line favorite, but competition runs deep in this $12,500 conditioned claimer for fillies and mares, which is scheduled for five furlongs on turf. True Heiress looks dangerous as she drops in class with leading jockey Edgard Zayas riding for trainer Steve Klesaris. Little Christina and My Masterpiece each is also capable of pulling off a small upset. It becomes a crapshoot it the race is washed off the turf. Race 8: Flim Fan, 6&#45;1 on the morning line, looks appealing in this wide&#45;open six&#45;furlong $20,000 maiden claimer. Trained by David Hawkes, he chased the pace before fading when he debuted in a key maiden special weight race on turf on April 21. Being a half&#45;brother to Truth Rules, who won the $150,000 Long Branch on the main track at Monmouth, he could thrive with the surface switch. The &ldquo;all&rdquo; button will be punched on more than one ticket. Race 9: La Chauffeur is the one to beat, rain or shine, in this one&#45;mile maiden special weight race on turf for Florida&#45;bred fillies and mares. Trained by Ralph Nicks, the daughter of Cairo Prince rallied to finish third in a similar race April 25. She earned a 65 Beyer Speed Figure in her last three races, all going a mile on turf in statebred maiden special weight races, and they are the best Beyers in the field. La Chauffeur also ran a decent race going six furlongs over a main track labeled good prior to his last three starts.
