How can four people fight the landlord to win?

According to the analysis of the card types of both sides, the biggest variable between them is whether the other four 10 will be bombed or two10;

1. Assuming that the opponent's four cards 10 will press the pop-up card, we will play cards as follows: 1. Our own team played first, and the opponent won without directly joining the 789 company. 2. If the opponent plays 7 after playing 5, then you play 8 or 9. If the opponent doesn't want to play the remaining pair of 8-9, the result wins; 3. If you fight 8 or 9, the other side is 4 10, you are in charge of the king's bombing, and then the remaining pair is 8 to 9, and the other side can't stand it, or you win! (Pay attention to this place, here we will still lose if the other side takes it apart 10. )

So the key for us to win is to prevent our family from splitting four10s into two10s.

Second, split the opponent's four 10 cards into two pairs of 10 cards:

1. Our own team goes out first, out of pair 7, and goes home 10 (the remaining pair 5, pair 7, pair 10), and we don't want it;

2. If the opponent hits 5, we will hit 8. If the opponent hits 10 again (with 7 hands left), we will directly bomb (with 4, 5 and 9 hands left);

At this time, it is obvious that if we play pairings, we will lose, so if we try to split pairings 7, we will win. For example, if he wants a single row of 4 or 5 (there is one 7 left), we will take the first 9, continue to give the single 9 and the remaining pair, and finally give the smallest single, so we will win!
