Stiff hands: 12 through 16

Hard 12–16 are the stiff hands. One more card can bust them, and on their own they beat nothing. They come up constantly, and they are where players lose the most money. One rule covers nearly all of them. Stand against a weak upcard (2–6), hit against a strong one (7–ace).

Take 14 against a 5, the standing case. Your 14 wins one way, the dealer busts, and from a 5 that happens about 42% of the time, the best bust rate in the deck. Hitting risks any 8, 9, 10, J, Q, or K, each of which busts you on the spot, to chase a total you barely need. Stand. The dealer is forced to draw, so let the risk sit with them. Standing costs nothing and wins whenever the dealer busts.

14 against a 10 is the opposite case. Standing wins only if the dealer busts, and from a 10 that is 23%. Standing on 14 v 10 loses about 54 cents per dollar. Hitting loses about 47. Neither is good. Every stiff-hand decision picks the smaller loss. Basic strategy often picks the least-bad option, not a good one. Players who cannot accept that a correct play still loses most of the time drift into never-bust strategies, and never-bust gives the house several extra percent.

Two exceptions. Hit 12 against a 2 or 3. Twelve is the least fragile stiff, since only ten-value cards bust it, and a 2 or 3 does not bust often enough to justify sitting on a total that beats nothing. Every other stiff against a weak upcard stands, including 12 v 4, the one that feels most wrong. It returns in the famous-cells Lesson.
