Hi Opt II is another card counting system used by advanced blackjack players. Like the Hi Opt 1 system, Hi Opt 2 is the second version of the highly optimum (efficient) systems. This one takes a little bit of work to get used to and provides slightly better odds than the other highly optimal card counting system. If you are planning on becoming a professional card counter and blackjack player, this method should be studied a little.

HiOpt-II是另一种常被高级玩家使用的算牌方法，是HiOpt-I算牌法的第二个版本。这种算法需要花点时间来掌握，但同时你能获得更高的胜率（相较于其它类似算牌法）。如果你决心做一名专业的算牌手，那么肯定要学习这种算牌法的。

One word of advice: Practice the Hi-Lo or KO card counting systems before using the Hi-Opt II method. Hi-Opt II has much more work involved but it truly doesn’t give you that much more of an edge. That small edge is golden when you are used to counting cards and trying to maximize the efficiency of your odds though.

建议：在学习HiOpt-II算牌法前，先练习掌握Hi-Lo算牌法或KO算牌法。HiOpt-II算牌法相对来说比较复杂，好像也没有为玩家增加多少优势；但要明白，对于21点游戏来说，任何一点微弱的优势，都是难能可贵的。

Difference between Hi-Opt II and Hi-Opt I

The major difference with Hi-Opt II is some cards are worth positive 2 or negative 2 count points per card. It is harder to keep track because you also have -1 and +1 valued cards to also keep track of. Another difference between the two systems is that you are counting the 7 and 2 point cards where the Hi-Opt I card counting system doesn’t. Both systems are balanced, meaning that when you start your count off at 0 at the beginning of the deck, you should have a final count of 0 at the end because the negative and positive counted scores cancel each other.

HiOpt-II和HiOpt-I算牌法的区别

最主要的区别是，在HiOpt-II算牌法中，有一些牌的计数值是-2或+2。再加上那些依然被记为+1、0、-1的牌，当然也就使得HiOpt-II算牌法会比HiOpt-I算牌法更难掌握。还有一个区别就是，在HiOpt-II中要记录2和7这两个原本在HiOpt-I算牌法中不需要记录的牌。但同样的，这两种算牌法都是“平衡”算牌法。

Hi-Opt II Card Counting Strategy

As with all card counting strategies, Hi-Opt II begins with the memorization of basic strategy. Basic strategy is a list of the “correct” moves to make for every combination of dealer hands to your hands to give the greatest mathematical edge. This edge will still not beat the house though, but this fine tunes your odds and lowers the house edge as low as possible. Next you implement your Hi-Opt II system and this will be the factor that beats the house edge when done successfully.

之前在《算牌法巡讲：HiOpt-I算法》中曾说过，所有的算牌法都是对基本策略表的补充。而仅凭基本策略表，玩家是赢不过庄家的，因为此时庄家优势依然为正数，只有辅以合理的算牌法并正确运用，玩家才可能战胜庄家。

The next part of the strategy is to memorize the table below to become a Hi-Opt II card counter. This is one of the hardest systems because of all the different cards and count points to keep track of. In the Hi-Opt II count table below, each card drawn corresponds to a count point. You start your count off when the deck is shuffled and the first card is dealt. You not only need to watch what cards you have, you also need to count the cards that the dealer has and everyone else’s cards on the table in order to get a good prediction of what cards are still left in the deck.

下表就是HiOpt-II算牌法的计数值对应表了，这是几种难度最大的算牌法之一，因为你需要跟踪并计算每一张牌。

So when you see a card, for example a 5, then add +2 points to your count total. If you get a ten card, then subtract -2 points from your count and so on. When the entire deck is used up, your count should be 0 as Hi-Opt II is a balanced card counting system.

When to Bet in Hi-Opt II Card Counting

关于HiOpt-II算牌法的下注时机

It is ideal to bet when many of the smaller cards are gone. A lot of high valued cards mean that your odds improve and this is the whole purpose of card counting by using the Hi-Opt II system. Therefore when many small cards are played, your true count becomes a large positive number. The higher this number, the more your edge increases and the more the blackjack house edge decreases. So it makes sense to bet more and often. On the other hand, a large negative running count means there are fewer ten cards and more small stiff cards in the deck, which decrease your edge and it makes sense to contract your betting. Card counting is great for indicating swings in “good” luck.

当发出的牌中小点数牌的数量远远多于大点数牌的时候，就是下注的好时机了。HiOpt-II算牌法的目的就是识别出牌盒中剩余牌的点数是否足够大，因为当越来越多的小牌被发出后，你的计数“真值”就会随之越来越大，你的优势也随之增加，相应的，庄家优势随之减少——这也是你下注并提高注额的时机。反之，则你就要减少注额、甚至不下注。其实，算牌法就是告诉你“好运气”是否来到了。

We also need to recall an important piece of information. The actual true count is the one that you are counting in the game. You need to pay attention to the running count. You can calculate and find the running count by taking the true count and dividing that number by the number of decks in play. For example, a true count of +4 in a 4 deck game has a running count of only +1. So you need to make your betting decisions based on your running count.

要特别提醒你的是，要用“真数”来作为你的决策依据。所谓真数，就是将计数值除以剩余的牌副数得到的数值。比如，计数值是+4，剩余4副牌，那么此时的真数就是+1了。

Also, the aces have a zero count in this system but this is something to watch out for. The real strategy says you need to make some very small changes to the basic strategy to account for the aces not being counted. You still need to keep track of how many aces are being played as well but that blackjack topic is extremely advanced and involves some mathematics.

还有，在HiOpt-II算牌法中，尽管Ace是记为零的，但仍然要特别关注Ace出现和剩余的数量。实际上，这涉及到对基本策略表进行些微的改动。而具体的理由和方法，因为涉及到许多的数学计算，就不在这里展开了。
