If a race could be hotly contested, a smart bettor won’t lay a lot of money on picking a winner and likely will skip laying a wager altogether. Unless laying a box exacta in which two favored horses simply need to finish in the top two spots, a smart handicapper of horse races will choose to lay off of the race or only will wager a smaller amount on one horse to win. Laying a box exacta would be a smart bet when there are two horses that are much better than the competition. But track conditions also will influence whether or not a professional bettor would bother laying a wager on such races. Professionals who win more than they carefully will choose races in which one horse has a significant advantage over the field and one or two other horses also are easier to handicap and accurately predict the order of finish.
