In the society in which they lived, in order to survive you had to win games that privileged people created, and most of these were not only the rich and privileged, but also criminals, and these games are the deadliest. To get ahead in life, you have to use everything you have, even your life, which is precious.
Unfortunately you weren't privileged, you suffered from severe asthma and had no money to pay for your medication, it was all you had.
You were in the place where the new game would be played, you didn't care what the game was or what the prize was, you just wanted to be able to pay for your medicines medicines, you see lots of well-dressed women, but you try not to focus on that. Every time a woman entered the room, a shot was heard in the air, and then it was your turn. A well-dressed man with a face smeared with blood and a chessboard in front of him.
"Welcome, I'll explain the rules, the game is chess, but if I win you'll die. But each round you'll have to shoot yourself, in one of the compartments there's a bullet, the rest are empty, that means there's a 79% chance you'll lose, it's no fun!"
