In Mahjong games, poker is a special operation that not only changes the progress of the game, but may also affect the final number of poker cards. Many Ma friends will ask:How many Hu does it take to fight Mahjong?？这个问题看似简单，但答案却因不同的麻将规则而异。本文将详细解析杠牌后的胡牌张数变化，帮助你在实战中做出更明智的决策。

1. The basic concept of bar cards

A bar card means that when a player has four identical cards in his hand, he can play them out to form a bar. Bars are divided into open bars and dark bars: open bars are when you touch the cards and then touch the fourth same card, or directly use the cards played by others; dark bars are when you already have four same cards in your hand. After the cards are tied, the player needs to fill a card from the end of the card wall and then play a card to keep the number of cards in his hand at 13 (or 14, depending on the rules).

二、杠牌对胡牌张数的影响

杠牌后，胡牌所需的张数会发生变化。在标准麻将中，胡牌的基本牌型是4副顺子或刻子加1对将牌，共14张。如果玩家杠了牌，那么杠的四张牌算作一个刻子，但占用4张牌的位置。因此，杠牌后，玩家手牌的总数会增加，但胡牌所需的牌型结构不变。

1. The relationship between ordinary Hu cards and bar cards

Without bars, players need 14 cards. If the player grabs once, the total number of cards in the hand becomes 15 (13 cards +1 replacement card +1 grabs card, but the grabs do not account for the number of cards in the hand. The actual hand is still 13, but one more card is needed when the card is played). In fact, after the card is played, the total number of cards the player needs to play will increase, because the card itself occupies the number of cards, but the number of chips in the card type remains unchanged. For example, if a player has a card, then when he has a card, in addition to the normal 4 decks of cards and 1 pair of generals, he needs an extra card to make up the fourth card of the card, so the total number of cards becomes 15 cards.

2. 不同麻将规则的差异

Mahjong rules in different regions have different regulations on the number of cards behind the card. For example, in national standard mahjong, the total number of Hu cards after the bar cards remains unchanged, but the number of the bar cards can be increased; in Sichuan Mahjong, the Hu cards after the bar cards are called "flowers on the bar", and the number of Hu cards may increase; in Guangdong Mahjong, the Hu cards after the bar cards may require more cards. Therefore,How many Hu does it take to fight Mahjong?There is no unified answer and needs to be judged based on specific rules.

3. The type of Hu card after the card

After the cards are dealt, the player may play the following card types:

  • flower on the bar: Touch your own card when making up the card after the card. This is a high-end card type.
  • snatch a beard：当别人加杠时，你可以抢杠胡牌，即胡那张被杠的牌。
  • Ordinary Hu Pai: After holding cards, you can reach the card conditions by touching or eating.

Among these hu card types, blooms on the bar and grab the bar usually have extra rounds rewarded, while ordinary hu cards are calculated based on the basic rounds.

四、杠牌策略与胡牌张数计算

在实战中，杠牌是否划算，需要综合考虑胡牌张数和番数。如果杠牌后胡牌张数增加，可能导致你更难胡牌，但杠牌本身带来的番数可能弥补这一劣势。例如，在国标麻将中，杠牌可以增加1番，而杠上开花可以增加8番，因此即使胡牌难度增加，也值得冒险。

此外，杠牌还可能影响其他玩家的牌型。例如，你杠牌后，其他玩家可能会改变策略，或者你杠的牌可能是别人需要的牌，从而阻止别人胡牌。因此，杠牌是一个需要谨慎决策的操作。

V. Summary

To sum up,How many Hu does it take to fight Mahjong?取决于具体的麻将规则和牌型。在大多数规则中，杠牌后胡牌的总张数会增加，但杠牌带来的番数奖励可能使杠牌成为有利的选择。玩家在杠牌前应仔细计算胡牌张数和番数，权衡利弊，做出最优决策。希望本文能帮助你更好地理解杠牌规则，提升麻将水平。
