Oscar Grind is a fictional character and the protagonist of Allan Wilson's book, published back in 1965. Grinde invented this strategy for roulette players, but it is so appealing to other fans of gambling that it is still popular today.

The basic principle - repeat a bet if it played

This strategy is based on the fact that we accept the main rule of winning in gambling. It sounds like this - "The probability of any event is 50%. It will either happen or not happen. You see? We don't take into account any factors here that affect the outcome in any particular event (match or contest). It's important for us to win money after several events and to do so in a guaranteed manner.

Hence, rule number two - if you are lucky and the bet is played, then the parimatch sports betting amount should be increased. If you lose, you leave it at the same level. A lot of private players use this rule without even knowing it - they believe, for example, that if a team is on a winning streak, it is more likely to win again than to lose. By the way, the same is true for the financial market - if the price of a stock rises, it is more likely to keep rising than to stop or turn around. The main thing here is to catch the turning point and stop in time.

Yes, you must have noticed that if you are lucky, you are lucky for a relatively long time, and if, on the contrary, there are failures, they do not end instantly.

Don't bet more than 1/12 of the pot

Let's focus on the numbers. The main (and maybe the only) reason the strategy didn't work is because the pot is limited. Roughly speaking, if you have an endless deposit, then at a long distance you will win in any case, if you play disciplined. If, however, the bank is limited (as it almost always is), you need to find an exact balance between the amount you have, the odds on the event, and the amount you bet on each particular bet. And the greater this difference, the more likely the total winnings on the interval.

There are different opinions about specific numbers. But, basically, they come down to the fact that the amount of the bet should not be more than 1/12 or less of the amount on deposit. For example, your deposit is $12,000. In this case, the bet should be no more than 1,000. This is the maximum. But again, if the deposit is larger or the bet amount is smaller, the probability of winning in the end after several bets will be higher, and in the case of unsuccessful outcomes, you will be able to continue playing, that is, the deposit will last longer.

The same goes for the odds. The higher odds you take, the sooner you risk losing the whole bank. The smaller, the more reliable. Sooner or later, luck will turn to you, you will start winning and you need to make sure that the deposit is not exhausted by this time. Odds higher than 2.00 are considered high. But then again, you can also play with high odds if you have a large amount in your account and bet a small amount. Here you need to find the exact balance, individual for you. Experience, practice and intuition will help.
