Pair of 9s vs a dealer 7
Basic strategyStand on 18.
Why
You split 9s against almost everything, but not the 7. A dealer 7 most often finishes on 17, and your 18 already beats that.
Splitting would break up a winning hand into two hands that each start at 9 and have to fight their way up. Standing keeps the edge you already have.
By the numbers
Average result per $100 initial bet, after the dealer checks for blackjack. A negative number is an average loss; the best play is the one that loses least or wins most.
| Play | Dealer hits soft 17 | Dealer stands on soft 17 |
|---|---|---|
| Hit | −$59.11 | −$59.11 |
| Stand | +$39.96Best | +$39.96Best |
| Double (2× bet) | −$118.23 | −$118.23 |
| Split (2 hands) | +$37.00 | +$37.00 |
| Surrender (if offered) | −$50.00 | −$50.00 |
Without surrender, stand beats split by $2.96 per $100 bet under either soft-17 rule.

How the table rules change it
| Table rules (4–8 decks, double after split unless noted) | Play |
|---|---|
| Dealer hits soft 17, no surrender Most Florida and Las Vegas tables | Stand |
| Dealer hits soft 17, surrender allowed Some higher-limit tables | Stand |
| Dealer stands on soft 17, no surrender Felt says “stands on all 17s” | Stand |
| Dealer stands on soft 17, surrender allowed Best common shoe game | Stand |
The answer is the same under every common rule set.
Common mistake
"Always split 9s." The full rule: split 9s against 2 through 6 and 8 through 9; stand against 7, 10 and ace.
Going further
Against an 8, splitting 9s is right because your 18 only pushes a dealer 18, and two 9s can beat it.
Drill it
This hand first, then the spots people mix it up with. The switches match your table’s rules and carry over to the full trainer.
Questions
Why split 9s against 8 but not 7?
Against an 8, the dealer's most likely total is 18, which ties yours. Against a 7, their most likely total is 17, which loses to yours.
Split 9s against a 10?
No, stand. A dealer 10 is too strong.
