Hard 16 Against a Dealer 9

Updated

Surrender, but only just. This is the narrowest surrender decision on the chart: giving up beats hitting by 0.5% of a bet. If your table has no surrender, hit without hesitating.

The short version
Every number on this page is computed for a six-deck game with our own solver, then checked against an independent reference. The calculator will do the same for your exact table and hand.

A nine is not a weak card

Players surrender freely against a ten and an ace and then talk themselves out of it against a nine, because a nine looks beatable. It is not. The dealer busts with a nine showing 22.9% of the time — barely more often than with a ten, and far less often than with any card from 2 to 6.

Worse, a nine most often finishes on 19, which beats every hand you can reach by standing on 16 and most of the hands you reach by hitting it.

What each option is actually worth

Six decks, dealer stands on soft 17, averaged across every two-card 16. Bet of 1 unit:

break even Surrender -0.500 Hit -0.505 Stand -0.543
Surrender and hit are almost touching. Standing is not close — that is the decision worth getting right.

Why such a thin margin still matters

0.5% of a bet sounds like nothing, and on one hand it is. The reason to take it anyway is that surrender costs you nothing to learn: it is a fixed −0.5, it never needs recalculating, and it removes a hand you would otherwise misplay under pressure.

If you are counting, this is also one of the first cells to move. At a high true count the extra tens make standing better than both, because the dealer’s bust rate climbs and your draw gets more dangerous at the same time.
