What is a DSA bet
An DSA bet, short for double stakes about, is a bet in the category of Up-and-Down bets, which is a type of ‘any to come’ bet. So starting at the beginning an ‘any to come bet’, often called a ‘if cash’ bet, is a conditional bet. A bet in which future bets are dependent on previous bets. An Up-and-Down bet is one such conditional bet, it is a wager on two selections and consists of two separate bets. A same stakes single bet will be placed on each of the 2 selections. If either of these two bets wins, a single bet will then be placed on the other selection. With DSA bets this stake will be double the amount that was put on the first bet (with different types of Up-and-down bets, different stake amounts may be placed for the second bet).
Double stakes about bets should generally be placed when both selections are above even money. This is because if the one or both selections are odds-on there isn’t enough money to be places on the next choice. Of course this is still possible but it just means the second bet will not have double the stakes, which is the whole point of the bet. Instead the whole amount won will be placed on the next bet.
As a DSA bet is two separate bets, we’ll need to calculate each bet separately. Also each of these two bets are broken down into two sections themselves. The following bullet points show this better
- Part 1: A single stake bet on participant 1
- Part 2: If part 1 wins, place a bet on participant 2 at up to double the stake
- Part 1: A single stake bet on participant 2
- Part 2: If part 1 wins, place a bet on participant 1 at up to double the stake
With DSA bets you will get a return on your bet even if just one of your choices wins, this may not make you a profit, but you don’t lose everything if one leg loses. The maths for one and two winners is different as below will show.
S = Stake
P1 = Selection 1
P2 = Selection 2
The Maths for both winning (remember 2S is double the stake or the maximum amount that can be bet if the odds are below even money – odds of less than 2)
((S x P1) – 2S) + (2S x P2) + ((S x P2) – 2S) + (2S x P1)
Maths for one winning selection
(S x Winning Selection) – 3S
This means if your one winning selection is less than odds of 3 you will still lose money, even though you will get a return from the bookmaker.
Example of how our DSA calculator works
Let’s see these calculations in action, for this example we are going to make it simple and have odds of greater than evens.
We are down the track and done our research, the two horses we believe the bookie is offering value on are at odds of 5.5 and 8; feeling confident we place a DSA bet of £100.
It’s our lucky day and both horses romp home in first place, so let’s put these odds into our formula for both horses winning.
Return = ((100 x 5.5) – 2 x 100) + (2 x 100 x 8) + ((100 x 8) – 2 x 100) + (2 x 100 x 5.5)
Return = 550 – 200 + 1600 + 800 – 200 + 1100
Return = £3650
This is our total return, but remember our original stake was £100, and as a DSA is two bets we must subtract £200 from this for our total profit.
