The first principle of playing mahjong is: safety first! Avoid guns and bars.
If it is against this principle, this pair of partners can't be removed! What is the purpose of opening a partner? It is to leave better partners to listen to better cards and ensure the success rate of Hu cards. Unless you are a big brand, by comparing "make it small, make it big", you can get much more than the loss of some guns.
The second principle of dismantling partners: you can't help your opponent to be a big card!
Many friends will make such a mistake: they want to play their own cards, regardless of the card potential, and lack the thinking concept of containment in their heads! I only think about my own cards, but I didn't measure that I would make cards after I removed them. Can my advantage be far greater than my opponent? You should give up if you are not far away. Think about it. I'll open 12. If someone touches two hands, it must be a draw. I just opened it. Can I make sure the painting? Certainly not, so my advantage is worse than others. This is thinking. In the face of this kind of game, what I want is to contain and slow down the opponent's progress.
The third principle of disassembly: it is beneficial to make my card bigger and stronger!
After observing the first and second principles in order, I will dismantle them from my interests! The order between them cannot be changed! At this time, the card splitting is mainly based on my number of cards, the success rate of Hu cards in the future, and my plan to make cards. Decide which partner to dismantle by comparison! I believe that all your friends have their own experiences and choose according to the rules of playing mahjong!
