The Preakness Stakes, with its post time of 3:18 p.m., features 10 horses, giving bettors an easier field to navigate than the 19-horse Kentucky Derby. Straight bets, which require at least $2 to place, include three types of bets â win, place and show. A win bet means you bet on a specific horse to win the race. A place bet means the horse needs to finish second or first. A show bet means the horse you're rooting for can place first, second or third. You win based on where the horse actually finishes, with exact selections paying out larger sums.
