“Oscar’s Grind” is the nickname given to a betting system popularized by Allan Wilson in the mid-1960s. It’s almost exclusively employed to even-money binary propositions, such as the reverse of a coin or, in the context of sports gambling, covering the spread.
It is like the D’Alembert System, to some degree, however whereas D’Alembert increases bet size following a loss, Oscar’s Grind aims to capitalize on winning streaks by upping bet size following a win (while waiting out losing streaks).
Below, we describe how Oscar’s Grind operates and why it doesn’t actually work in real life.
How Can Oscar’s Grind Operate?
Oscar’s Grind divides betting into”sessions” and”units” Every session starts with a one-unit bet and finishes if the bettor has achieved a one-unit gain.
For most people, using real dollar amounts makes it easier to comprehend.
Pretend that your”device” is $100. All your sessions will begin with a $100 wager. It will end just when you have a $100 profit.
For mathematical simplicity, pretend there is not any juice when betting against the spread (“ATS”), which winning a $100 ATS wager is going to result in a $100 gain. (In reality, it ends in a $90.91 profit with the standard -110 odds in impact.)
In the event that you win your first bet of $100, you’ve achieved the sought-after $100 gain along with also a new session starts.
In the event that you lose your first $100 bet, Oscar’s Grind dictates that you continue to wager $100 (a.k.a. one unit) until you win a bet. When you (eventually) win a bet, the bet size doubles to $200. It remains $200 until :
You lose again, at which time it raises by a different device (to $300), or
Gambling a lesser amount could potentially result in a $100 gain.
Again, using illustrations will make this simpler to comprehend.
