Hard 12 Against a Dealer 2

Updated

Hit. This is the hand where the rule everybody half-remembers — “stand on a stiff against a weak card” — breaks down, because a two is not a weak card. Standing costs 4.0% of your bet.

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 two is the strongest of the “weak” cards

Dealer bust rates by upcard are not flat across the low cards. A dealer showing 2 busts 35.4% of the time; a 5 busts 41.8% and a 6 busts 42.3%. That seven-point spread is the whole reason 12 is played differently against a 2 than against a 5.

Standing on 12 means you win only if the dealer breaks. Against a two you are asking a 35% question. Hitting gives you a live hand roughly 69% of the time, because only a ten-value card busts a 12.

What each option is actually worth

Six decks, dealer stands on soft 17, averaged across every two-card 12. Bet of 1 unit:

break even Hit -0.254 Stand -0.293 Surrender -0.500
Both live options lose, but hitting loses noticeably less. Surrender would be a large mistake on a hand this cheap.

Where the answer flips

Against a 2 and a 3 you hit. From a 4 onward you stand, all the way to a 6, and then you hit again from 7 up. That gives the 12 row an unusual shape: hit, hit, stand, stand, stand, hit, hit, hit, hit, hit.

The flip between 3 and 4 is genuinely close — see 12 against a 4, which is the tightest non-surrender decision on the chart and the one published charts most often get wrong.
