Perhaps the biggest difference between
betting on horse racing and other types
of sports betting is that to be successful
at betting on horses one must have the
ability to find the
overlay.
In horse racing parlance, the overlay
is a horse that’s going off at higher
odds than one’s personal betting
line dictates. To understand more clearly
let’s look at football betting.
In NFL betting, an overlay occurs when
a team is giving up less points or getting
more points than the bettor believes the
team should. For instance, if the Oakland
Raiders are underdogs to the San Diego
Chargers and the betting line is 8.5 in
favor of the Chargers and you believe that
the Chargers are no more than 6 points
better than the Raiders, then the Raiders
are considered an overlay bet.
Horse betting lines work the same way,
in the sense that horses that go off at
higher odds than the horse bettor believes
the horse should be going off at are solid
horse bets.
Let’s take a look at a couple of
examples that illustrates the concept of
overlays.
The first race we will look at is the
Kentucky Derby. The favorite in the Kentucky
Derby was Street Sense. He went off at
9 to 2 and ended up winning the Kentucky
Derby. Now, personal handicapping is an
art, but based on Street Sense’s
history at Churchill Downs, where the Kentucky
Derby is held, the horse should have been
going off at horse betting odds of 2 to
1 or maybe 5 to 2. The reason is that Street
Sense’s best race occurred at Churchill
Downs. Not only did his best race before
the Kentucky Derby occur on the same track
but he scored with a much better speed
rating than any of the other horses had
ever received.
Street Sense’s trainer, Carl Nafzger,
had won the Kentucky Derby in 1990 with
Unbridled. Therefore, his trainer knew
how to get a horse to the Derby and also
knew how to win it. To place things even
more into Street Sense’s favor is
the fact that his jockey, Calvin Borel,
calls Churchill Downs home.
All of these factors pointed to Street
Sense being a short-priced favorite in
the Kentucky Derby. The fact that he went
off at odds of 9 to 2 means that Street
Sense was an overlay in the Kentucky Derby.
There was also an underlay in the Kentucky
Derby in the horse Curlin. Curlin went
off at 5 to 1 in the Kentucky Derby. Although
those are higher horse betting odds than
one got on Street Sense, make no mistake,
Curlin in the Kentucky Derby was an underlay
while Street Sense was an overlay. Going
into the Kentucky Derby Curlin had only
run 3 times. He had just broken his maiden
in January. His trainer had never won the
Kentucky Derby nor saddled a horse that
had finished in the top four in the race.
Curlin had never run on the Churchill
Downs surface. Had never run a mile and
quarter before. Had never run in a field
with more than five other horses. In other
words, Curlin was hopelessly outmatched
when it came to running against a seasoned
veteran like Street Sense. In order to
place a wager on Curlin, a true horse bettor
would want at least 6 to 1 odds and not
the 5 to 1 that he or she received on Curlin.
That made Curlin an underlay.
What really illustrates the concept is
that two weeks later, in the Preakness
Stakes, the two horses changed overlay/underlay
positions. While Street Sense was the overlay
in the Kentucky Derby, it was Curlin who
went off as the overlay in the Preakness.
The Preakness Stakes always sets up much
differently than the Kentucky Derby. Although
Curlin went off as the 3 to 1 second choice,
in reality his odds should have been closer
to 2 to 1. The Preakness set up as a two
horse race once it was confirmed that Hard
Spun, the speedster in the Derby, was going
to face pace pressure in the Preakness.
This meant that the two logical horses
to bet on were Curlin or Street Sense.
Street Sense, coming off the Kentucky Derby
win, went off at terribly underlaid odds
of around 6 to 5 or so. Curlin’s
3 to 1 was as close to a gift as any horse
bettor is likely to encounter. There were
far less horses in the Preakness than the
Derby and save for Hard Spun, who was likely
to get cooked in a speed duel on the lad,
all of the other horses in the race were
untested.
Curlin had learned a valuable lesson in
the Kentucky Derby and there was no doubt
that the horse would take that lesson and
apply it to his run in the Preakness. He
did so and beat Street Sense by a nose.
It doesn’t always work out this
way, of course, but by trying to find overlays,
and not necessarily which horse is most
likely to win, horse bettors are much more
likely top show a profit in the long-run.
What every horse bettor should think about
before placing his or her horseracing bet
is which horse has a chance of winning
relative to the odds that the horse is
going off at. That’s how overlays
are found and the only way to show a profit
betting on horses is to bet on overlays.
