Betting on the two cards held in Saudi Arabia on Friday and Saturday will be widely available through account-wagering operations and many brick-and-mortar sites in the U.S., along with countries in Europe, Scandinavia, and Africa, according to the host of the pool.Takeout for win, place, and show bets will be 20 percent, according to the officials, while all other wagers – including exacta, trifecta, superfecta, and linked bets like the pick 3, pick 4, and pick 6 – will be 27 percent. Bets from all countries participating in the pool will be commingled.Among the other wagers that will be available in the international pool is the Omni, which requires a bettor to select two of the first three horses. The Omni, which can go by different names in different countries, is popular in many international jurisdictions but has failed to catch on among North American bettors during limited experiments. The international racing world will have its sights set on King Abdulaziz Racetrack in Riyadh on Saturday due to the inaugural running of the Saudi Cup, worth $20 million. The race has drawn five American entrants, and four are expected to be among the favorites in the 1 1/8 mile dirt race.
