# Chapter 4: The tactics of the early seven pairs of _19 cards and 28 cards (2)

Let us first analyze the solitary 19 cards in the early seven pairs (0-2 pair sub-period).

• In Chapter 3: Seven Pairs medium-term tactical _19 brand analysis (six) in about over, if solitary Zhang cards corresponding rib 19 cards (4.6 license) when a pair of sub-19 cards should be destroyed lone sheets , that is, 144 combined to play 1; 669 combined to play 9. Then in the early days of the seven pairs, you can also cater to this tactic. The 14 combinations will also play 1, and the combination will play 9. This is because it is better to judge whether the situation tends to the subfield than the one that is in pairs. The general card efficiency is also a cut-off paradigm that supports 14 dozens, 69 hits, and 9 points. At this point, the card efficiency of the sub-system and the general card efficiency are highly affinitive.

So what if you are completely alone, 19 cards, and no corresponding ribs?

• In the early days of the seven pairs, there is actually no need to pay too much attention to the Lonely 19 card. "19 cards are very important" refers to the concept of the seven pairs of late (5 pairs, always listening), and the importance of the seven pairs of late cards. The order is “Customer Winds and Winds> Campaign Cards>19 Cards>28 Cards>3~7 Cards”, that is, the importance of the 19th card in the later period is only the third. If you look at the types of cards mentioned above, you will find that there are 3 types of winds, 3 types, 4 cards, 19 cards, 6 cards, and 28 cards, which means that the seven pairs are 28 cards. It is also impossible to replace the 19 cards. In the late seven pairs, there are only three left in the lonely, and the wind and the cards in the early and middle stages are enough to cover the three solitary sheets. Therefore, it is advisable to actively knock out the completely lonely 19 cards at the beginning of the seven pairs.

Then let's take a look at the 28 cards.

• In the third chapter: the seven pairs of mid-term tactics _ number card 5 analysis (four) and the third chapter: seven pairs of mid-term tactics _28 card analysis (five) two chapters, 2·5·8 cards It is not an important card for the seven pairs. In other words, it is no problem to actively kill the Lonely Zhang card. The question is how to weigh 19 and 28 cards. If you consider how to better grasp the wind direction of the subfield, 28 cards>19 cards (since the 28 cards are paired to isolate the 19 cards on the outside, and the 19 cards have no special effect on the pair); If the card is easier to read, the 19th card > 28 cards (because the utilization rate of the 19th card is lower than the 28 card). However, it is worth noting here that the high precision of the 19-card reading mountain refers to the stage of the middle patrol and the final patrol. For the early stage of the seven pairs, the stock of the various brands is very large, and it is not necessary to reserve 19 Cards - This level of importance is only the third card and sacrifices the opportunity to grasp the wind direction of the sub-field, that is, the tactical idea of ​​the early seven pairs is to grasp the wind direction of the sub-field. As a result of this development, when splitting the 12 or 89, you should first remove 19 and then remove 28.
• Of course, there are considerations for the possibility of keeping the smooth and straight. The split side is first removed and then removed 28 because the 1 and 28 cards can be combined with the 23 cards and become a combination of 23 and 78. Listen), but 19 cards do not have this possibility. 2, 28 cards can be converted into a combination of 24 and 68 because of the 46 cards. That is to say, at this point (that is, the initial tactics of the seven pairs), the efficiency of the sub-cards and the general efficiency of the cards are still relatively large, and they are not completely opposite and have no brains to play seven pairs.

In a nutshell, the early tactics of the seven pairs (0-2 pair sub-period) are in a soft way to deal with the peace and smoothness of the hand in the case of retaining the pair. It is also common to remove the pair to make peace on the way. (This depends on the number of peace of mind and the number of foolish hands on the hand). However, if the number of sub-numbers reaches three, it is necessary to carefully weigh whether it should be biased toward peace or seven pairs. This is the "seven points of divergence - three pairs of sub-periods."
