The house edge is a statistical way of measuring the casino's advantage over the player. In blackjack, insurance is a side bet which is separate to your original stake. Offered only when the dealer's upcard is an ace, it acts as a safety net against an opposing blackjack. An insurance bet is usually half your original wager and pays 2 to 1. The side bet is. The following blackjack abbreviations and acronyms are used throughout this book and are typical of those used in the literature. When evaluating a game, you should assume Las Vegas Strip rules which include double on any first 2 cards, re-splits to 4 hands, dealer stands on soft-17, insurance allowed and, of course, a natural blackjack pays 3. What Does a Split in Blackjack Mean? A split solution means that you play two hands instead of one after getting the initial hand. Each hand is played solely, which. What splitting in blackjack means is that when your hand consists of two cards with similar value, you can split them by placing additional bet, creating two hands that will be played separately. The option to split is of enormous value; if it's used wisely of course.
byAmong my recent emails from players, I have several on the topic of splitting tens. One player mentioned that he seems to win more often than not when splitting tens against a dealer 5 or 6, so he was wondering if the play could be justified. Actually, his basic assertion is correct. You will win more often than not when splitting tens in those situations. But, winning more than 50% of the time is only part of the story.
When the dealer has a 5 or 6 up, he will bust more than 40% of the time. That's why basic strategy against those dealer upcards becomes quite a bit more aggressive. You should double 9, 10, and 11. Among soft totals, you should double A2 through A7. So, if you are dealt a pat 20, why not split the pair and get more money on the table while the dealer is weak?
Like all of basic strategy, this decision comes down to which action makes you the most money in the long run. Your single hand of a pat 20 is worth more than double what a single hand starting with a ten is worth.
Splitting Tens costs you money.
Assume we are playing a 6 deck, H17 game and we are dealt a pair of 10s against a dealer 6. Our initial bet is $10.
If we stand with 20, we'll win our $10 bet 78% of the time. We'll push with a dealer 20 about 11% of the time, and lose to a dealer 21 another 11% of the time. On average, we'll win $6.77 by standing.
If we instead split the tens (only once) and put a $10 bet on each hand, what happens? On average, each of these hands is still a winner, but the average win on each hand is only $2.78. Our total expected win on both hands combined is just $5.56, which is more than $1 less than the value if we had just stood on the 20. Despite having twice as much money bet in a favorable situation, we are now expected to win less overall.
If it's bad to split tens just once, it is of course worse to resplit them. If your strategy is to split tens and resplit up to the usual three times allowed, your total bet will be either $20, $30 or $40. Over all of these possibilities, your expected profit drops further yet to a grand total of only $4.51, more than $2 less than the value of your initial single $10 bet on a pat 20.

What about card counters?
Despite the risk of confusing basic strategy players, I can't talk about splitting tens without addressing what happens if you count cards. Because card counters have extra information about the remaining cards to be dealt, they are able to identify occasions when splitting tens does become the mathematically correct play. In our example game, the Hi-Lo index number for splitting tens against a dealer 6 is +4. (For indexes for other specific games, see our Advanced Blackjack Strategy cards.) When the true count is at +4 or higher, the value of multiple hands surpasses the value of the pat 20.

Having said that, even if the true count indicates that the play is warranted it may still be a bad idea to split tens. Because the act of splitting tens draws so much attention, most card counters choose to ignore the index for splitting tens, and just keep the pat 20 regardless of the count. In some casinos, the dealer is required to announce to the pit when a player splits tens. Pit bosses know that only two kinds of players split tens… Those that don't know any better, and those that know full-well what they are doing. If you are a card counter, you had better be sure the pit thinks you are completely harmless before you split tens. If they already view you with any suspicion, this move will confirm it.

In any case, I want to be perfectly clear about one point…
Basic strategy players shouldn't split tens. Period.

Just don't do it. It may seem fun, and it may be exciting. But splitting tens is just giving the casino extra money. They don't need any extra. Stand with your 20.

Man that was an awesome read . And now that I've read this I understand a lot more of what's truly going on . I'm an excellent basic strategy / bet/ knowing when to double and split . All my friends we picking on me cause I wouldn't hit those strong hands . But they were two hundred dollars down in one five deck shoot . I played for two hours , walked away with 300 only starting with fifty .
I was glad to know that someone with all this knowledge chose basic strategy, or excellent basic strategy as the technique of choice due to the house edge factors .
Thanks man , great article
