Should You Split 8s Against a Dealer 10?

Figures checked against the rules of the live table.

You have a pair of 8s. The dealer turns up a 10. Basic strategy says split — put a second bet out and play two hands. It is the play players argue with most, because it feels like throwing good money after bad. The short answer: you are going to lose money on this hand on average whatever you do. Splitting is the option that loses the least.

Why 16 is the worst hand in blackjack

Keep the 8s together and you hold a hard 16. Stand, and you only win when the dealer busts — with a 10 showing, that happens roughly one time in five. Hit, and any card from 6 through king busts you: 8 of the 13 ranks, about 62% of the time. Both choices lose well over half the money you put on the hand over the long run.

What splitting changes

Split, and each 8 becomes the start of a new hand. An 8 is a decent starting card: a 10-value card turns it into 18, a 3 makes 11 for a double, and with double after split allowed on Halfonred you can press those good starts. You stop playing one terrible hand and start playing two mediocre ones.

Split the 8sLose about $48

Splitting puts twice as much on the table and still loses less in total than playing one 16. That is the whole argument. The figures above are long-run averages for six decks with double after split; the exact cents move a little with the rules, but the order does not.

What about against an ace?

Split there too. Some games offer surrender, and in those games certain charts give up 8,8 against an ace when the dealer hits soft 17. Halfonred does not offer surrender, so the choice is between splitting and playing 16, and splitting wins.

The feeling versus the math

Splitting 8s against a 10 produces memorable disasters: two hands of 18 against a dealer 20, double the bet gone. Those hands stick. The far more common outcome — one hand wins, one loses, or the dealer busts and both win — does not. Over hundreds of hands, the split saves you money you would never notice losing by standing.

This is one cell of the full six-deck basic strategy chart. The rule for 8s is simple: always split them.
