If you have the ability to take it, the person who takes it behind will definitely win. The key is to make sure that there are still four games on the table in the final round.
So let A take it first: A takes 1 and B takes 3; Party A takes 2 and Party B takes 2; If A takes 3, B takes 1.
Make sure that the total number of matches taken by A and B is four, then there are four matches left on the table in the last round, and A can only take 1~3, then B wins.
Similar to the game: Count to 30.
Rules of the game: based on two people, each person can add 1~3 to the original number every time, and whoever counts to 30 will lose. The game skills are as follows:
At 30, you lose: you have to grasp these numbers in turn: 2, 5, 8, 1 1 4, 17, 20, 23, 26, 29.
Win by 30: Grasp these numbers in turn: 3, 6, 9, 12, 15, 18, 2 1, 24, 27, 30.
Count to three:
At 30, you lose: you have to grasp these numbers in turn: 1, 5, 9, 13, 17, 2 1, 25, 29.
At 30, you lose: you have to grasp these numbers in turn: 2, 6, 10, 14, 18, 22, 26, 30.
