What is the 2-1-2 method? (2-1-2 system, New York system) How to do it, etc.

Bakara-chan

This betting, given from New York's area code 2-1-2, is pretty simple.It's easy.
You just bet on 2 credits → 1 credit → 2 credits.
It is often used mainly in baccarat, roulette even, and BJ, where the payout ratio is doubled.
There are eight patterns below.

merit and demerit

Merit

-Since there is no big loss, the funds will not be reduced at once
・ You can play around
・ If you win 3 out of 2 times, you win

Demerit

・ Since there is no big win, the funds will not increase at once.
・ It's boring
・ If you lose 3 out of 2 times, you lose

Realistic consideration

Bakara-chan

Now let's consider whether it can actually be used in practice.
As you can see from the above pattern, there is no doubt that it is a betting that you can play for a long time without a big win or a big loss.
If you win 3 times out of 2 times, you win, and if you lose 2 times, you lose.

General user

Certainly it seems to be playable in the long run, but it can't be used very much as a user looking for a win, isn't it?

Bakara-chan

Well, it's good to play, but it's a delicate place if you can keep winning.
After all, you win or lose, but since it is 1/2, even if the pure win rate is 50%, it will not be a plus or minus, and if it is red and black of roulette, you will lose that return rate, so it is almost the same as a flat bet. right.
Let's take a look at each pattern.

Bakara-chan

The expected value (?) Does not change even if you cut it when you make a profit, but 8 out of 5 patterns win and 3 patterns lose, which makes a difference.
In other words, the probability of winning is 8/5 (8%) if you say only the wins and losses out of the 62.5 patterns.

If you cut when you lose

Bakara-chan

Even if you lose unconditionally, the expected value (?) Does not change and the winning and losing patterns are the same.
By the way, even if I cut it when a loss occurs, it was a similar feeling, so the fundamental point is the same.

summary!Ketsuron!application! (?)

Bakara-chan

I don't lose much like that, but it's not a way to win, so it's a betting game for people who want to play for a long time.
Normally, the maximum drawdown (maximum loss amount) is 5 units, so even if you lose 12 games in a row, you will only lose 20 units.
I think that's the good point.

General user

I see.
It may be a betting that will be a plus in a sense for those who get hot and plunge into it.

Bakara-chan

Yeah lol
If you dare to apply it, for example, if you say the usual 8 patterns, the balance will be 1 patterns of 3 unit, 5 units, 1 units, minus 3 unit, minus 5 units, minus 6 units.
What if I went one set and lost and lost money, I would combine this with the love shale method?

Example)
・ 3 consecutive losses and minus 5 units → Make a sequence with a love shale legal feeling
・ In the sequence, 1 unit is added to the loss (1, 4, 4) and the bet amount is 212 units.Start the XNUMX method again with these XNUMX units. (The balance pattern is the image below)

・ If pattern 1 or 3 is used here, the balance is positive, so the end.
・ If the pattern is 2 or 4, subtract 2 from the sequence to get (1,4), so next, start the 5 method in 212 units. (Subtract the profits from the sequence) (I think you can start the 1,2,2 method in 3 units with 212)
・ If the pattern is 5 to 8, the loss is increasing, so add it to the sequence. (If it is pattern 6, it will be a sequence such as (2 or XNUMX). When adding a sequence, you can add it as it is, or divide it by XNUMX and add it. It's okay. Whether or not to postpone the game.)
・ As a point of caution, if the unit is an odd number, it is a bad idea, so it is desirable to use an even number.
・ If you lose 3 consecutive games (9 consecutive losses in total), the sequence will be (XNUMX, XNUMX, XNUMX, XNUMX, XNUMX).
・ If you lose, you will catch up after all, so you may be able to take it all at once.

Bakara-chan

I don't recommend it because it will end up catching up, but it's like recovering the loss by raising the bet amount in the same way as the Love Sher method or Monte Carlo method for the loss of 5 units that came out first.
I don't think it makes sense to look at it, but I feel like I don't have to know it lol
The betting is like adding the Dalambert and Monte Carlo methods, so if you lose a lot and can't stand the drawdown, you'll die, but if you can return the winning percentage to near the average, even if the winning percentage is low. It feels like you can make a positive balance.
I hope you can think of it as a combination of betting like this.
I don't know what it means so much, but this site is probably the only betting ... lol
That's it!Closed!

end!
