Money on Splitting vs. Standing with a Pair of 10s

When being dealt a pair of 10s in blackjack there are really only two options for plays: splitting or standing. You cannot hit, not with a hand total of 20. The rule of thumb with a pair of 10s in a game of blackjack is to stand—no splitting! This is because a pat 20 is a strong hand.

But you will find that some blackjack players would rather split a pair of 10s when faced with a dealer 5 or 6. They are the two cards with the highest probability of ending in a bust for the dealer. The thought process is that if the dealer is more likely to bust with those two up cards, why not split the pair of 10s and try to make the most off of the round.

Odds on winning when splitting a pair of 10s against a 5 or 6 is not too shabby: 63% and 64% respectively. Best case scenario, meaning splitting against a 6, you stand to win \$56. And that is \$56 total; each hand would have a profit of \$28, and together that is \$56. All in all, the odds and profit are not too shabby.

But I think you might change your mind when you look at the odds and potential profit for standing on a pair of 10s against a dealer’s 5 or 6.

The odds of winning against a dealer’s 5 or 6 when standing on a pair of 10s is 84% and 85%, respectively of course. Already the money bells in your head should be beginning to go off. Again, looking at the best case scenario of facing a dealer’s 6, 85% is a better odd than 64%. That also means that the potential profit is higher too.

Now I know the money bells are going off.

So if you stand to win 85% of the time by standing on a pair of 10s in blackjack, that means you stand to lose only 15% of the time. Subtract 15 from 85 and you get 70, and \$70 is the profit per \$100 if you stand on a pair of 10s in blackjack against a dealer’s 6; profit on standing against a dealer’s 5 with a pair of 10s is \$68 per \$100. Still not bad. And certainly more profitable.

And profit is the point behind strategy in blackjack. Strategy is there to improve your odds at winning in blackjack, and winning means more opportunities to make a profit. Knowing the difference in odds between plays helps. In this case, you know that standing on a pair of 10s against a 5 or 6 will give you around \$14 more per \$100.
