Rebirth: Making money is a million times easier than falling in love

Chapter 7: 5x Leverage

Looking at Hai Ge and the other man, Lin Qi said in a deep voice, "I have twenty here. I want to multiply the leverage by five times and play with you for a hundred."

Hai Ge wasn't stupid; naturally, he wouldn't agree to such conditions.

However, before he could speak, Lin Qi added, "To be fair, I'll also multiply the odds by five, you don't need to."

In other words, if I lose, I'll pay you 500; if I win, you can just give me 100.

"How about it? Do you dare?"

Upon hearing this, Hai Ge and his companion were taken aback and subconsciously exchanged glances.

Only a fool would come up with such conditions, right?

According to this calculation, Lynch is essentially using 25 times leverage. If he loses, wouldn't he also lose 25 times the amount?

On their side, they only need to play normally; even if they lose, it's only a hundred, so there's no risk at all.

Is this kid really that confident?

For a moment, a hint of doubt began to creep into Hai Ge's mind.

Could it be that Zhang Haozhe discovered they were conspiring to frame him, so he deliberately hired this guy as an accomplice?

What if this kid is some kind of billiards master like in the movies? Wouldn't we be doomed?

After thinking for a moment, he winked at Ma Chao by the window, and the two of them went to the corner of the wall.

"Who is this kid? Do you know him?"

Hai asked in a low voice.

"A little guy from my village."

Ma Chao explained in a low voice, "He's also in high school, the same school as Zhang Haozhe."

Hearing that Lin Qi was also a high school student, Hai Ge felt much more relaxed.

But he pressed on, asking, "Does he know how to play billiards?"

"Probably not?"

Ma Chao glanced back at Lin Qi and muttered, "Anyway, I've never seen him fight before, not even when we were kids."

"That's good."

Hai Ge was relieved.

"Do you want to fight him?"

Ma Chao hesitated slightly.

He and Hai Ge conspired to cheat Zhang Haozhe because Zhang Haozhe's father was the village chief and his family was wealthy.

But he had heard about Lin Qi's family situation; he was told they were heavily in debt and living a difficult life.

Seeing that Hai Ge was really going to fight Lin Qi, he felt a little uncomfortable.

They're from the same village, so isn't doing this a bit too much of kicking someone when they're down?

"What's wrong?"

Hai Ge glanced at him: "You want to take his place?"

"Well……"

Ma Chao hesitated for a moment, but ultimately didn't dare to speak.

Hai Ge treated him well, and thanks to Hai Ge's ball skills, he also made a lot of money during this period.

If he offends Brother Hai, he won't get a share of this business.

Seeing that he swallowed his words, Hai snorted and returned to the billiard table.

"How is it?"

Lin Qi looked at him calmly: "Have you reached an agreement?"

"Okay, let's play it your way."

Hai chuckled and gestured to his female companion beside him, "Let's set up the ball!"

Seeing that he had actually agreed, Zhang Haozhe's face turned ashen.

"This is it..."

He muttered to himself, "It's all my fault, I dragged Lynch into this too..."

"Don't be afraid, watch me."

Lin Qi patted him on the shoulder, offered a word of comfort, then went to the table, picked up the gun powder, and wiped the gun tip.

With five times leverage and five times the odds, his risk is indeed very high.

His probability of winning is 50%, but the winnings are only 100 yuan, which is equivalent to 500% of his principal.

But if he loses, his loss will be -500 yuan, which is equivalent to -2500% of his principal.

Based on this probability, his expected return is also negative, which is -200 yuan.

The expected rate of return is -1000%.

Correspondingly, Hai Ge's winnings are 2500%, and the expected return is a positive 200 yuan, so no matter how you calculate it, he's making a profit.

Therefore, he must ensure that he has a greater than 83.33% probability of winning in order to be confident in playing this game.

However, this is only the apparent probability.

In Lynch's view, he used 20 dollars' worth of chips to get a chance to win 100 dollars, a return of up to five times!

As Marx pointed out in Capital, "If there is a 10% profit, capital will be used everywhere."

With a 20% profit margin, capital will become more active;

With a 50% profit, capital will take risks;

For the sake of 100% profit, capital dares to trample on all human laws;

With a 300% profit, capital will dare to commit any crime, even risking the gallows.

A 500% profit on this deal is already a great deal.

Moreover, regardless of any conditions, his probability of winning is 50%.

The odds of winning are already very high.

Lynch had no initial capital, so taking risks was inevitable.

Moreover, he did not believe that his chances of winning were only 50%.

He is not good at most sports.

But billiards and golf are the only two sports he can play at a high level.

Billiards, in particular, allows him to perfectly utilize his keen intuition for numbers and geometry.

He has never played professional matches, but he has played with Ding Junhui privately.

After playing a few times, Ding Junhui stopped playing with him.

Ding Junhui said that when he plays billiards, he's like a robot, completely devoid of emotion.

But he preferred to believe that it was just Ding Junhui saying those hurtful things because he couldn't accept defeat.

After all, given enough time to calculate and aim, Ding Junhui is no match for him.

Hai Ge's female companion was very skilled and set up the ball in no time.

He feigned generosity and politely told Lynch, "You can tee off first!"

"it is good."

Lin Qi didn't give him a chance to back out and agreed immediately.

They're playing a game of Black Eight, not snooker, where the player who breaks first has a 3% advantage.

Seeing Lin Qi back down gracefully, Hai Ge was somewhat surprised and slightly astonished.

Could this kid be a wolf in sheep's clothing?

However, when he saw Lin Qi's opening stance, he immediately felt relieved and even gave the blond guy next to him a Donnie Yen-esque smile.

Lynch placed the cue stick on the table, then held the front of the cue stick between his left index and middle fingers and pressed it down firmly.

This posture is only used by beginners who have just learned billiards.

That's so unprofessional!

Hai Ge smiled and shook his head, already feeling seventy percent certain of victory.

Behind Lin Qi, Zhang Haozhe, who saw him assuming a hitting stance, covered his forehead, unable to bear watching what was about to happen.

However, the commotion around him did not affect Lynch.

He leaned down, gripping the cue stick firmly with his right hand. His gaze followed the cue stick, landing on the cue ball, and then looked at the triangular pile of balls in front of him.

In his line of sight, the front of the club seemed to extend outwards along a line that only he could see.

The extended line lands on the cue ball, then refracts on the surface and continues to extend backward.

Staring at the top of the cue stick and the cue ball, a series of formulas flashed through Lynch's mind.

If we consider the billiard ball as a rigid body, and the table has friction, then let the mass of the billiard ball be m, the radius be R, and the moment of inertia be I = 2/5 mR squared.

The cue stick imparts an impulse I_impulse to the cue ball, and the cue ball gains a center-of-mass momentum of I_impulse = mΔv, and the center of mass gains a translational velocity v0.

If the point of impact does not pass through the center of the ball, a torque will be generated, which will produce angular impulse, giving the ball an angular velocity ω.

When v=ωR, the ball rolls purely the moment it hits the table, and the point of impact is approximately 0.4R above the center of the ball.

Lynch slowly moved the cue stick, aligning the tip with a position approximately 11.42mm above the cue ball.

The extended line also extends from behind the cue ball, landing in front of the red ball at the very top of the pack.

Without actually hitting the ball, Lin Qi was calculating rapidly in his mind.

The standard radius of a billiard ball is approximately 28.55 mm, and its diameter is 57.1 mm.

The distance from the tee line to the pile of balls is approximately 1600mm.

The easiest place to score is on the outside of the second ball in the pile, where you slice it thinly, specifically the one just below the top corner.

If the angle between the line connecting the centers of the two balls and the direction of the cue ball's incident shot is θ when the balls collide, then with topspin, the separation angle is < 90°, and with backspin, the separation angle is > 90°.

两球心最小距离是57.11mm，目标进球所需的切角厚度在1/4到1/3之间，对应几何偏距大概是19mm。

Therefore, the final required horizontal deflection angle is tanα = b/L = 19/1600 ≈ 0.0119.

It is approximately equal to 2°.

Lynch slightly moved the club, shifting the tip slightly to the left.

The extended line also moved, landing outside the second ball in the pile.

"Are you done yet?"

He had been eyeing the area for a while, while Hai Ge and the other man on the opposite side were getting impatient.

The blond-haired guy couldn't help but urge, "Are you even capable? If you can't handle it, then forget it, don't..."

But before he could finish speaking, Lin Qi moved.

Snapped!

With a crisp sound, the cue ball shot out and accurately struck the second ball in the pile.

Whoosh!

The balls scattered and rolled around on the table.

The number 3 ball that was hit bounced off the side cushion and slowly fell into the bottom hole.
