12 vs 3
Hard 12 versus a dealer 3 is a hit in all 32 PlayCorrect rule mixes. It is closer than 12 vs 2, which is why it feels controversial, but standing is still the worse of the two. Educational, 21+, not gambling advice.

Closer than 12 vs 2, still a hit
Under default six-deck S17, hitting beats standing by about 0.0196 units — less than the 0.0405-unit gap on 12 vs 2, more than the razor-thin stand on 12 vs 4. All four two-card compositions agree on hitting vs 3 in the default set. The cell was in the 30-cell spot-check (both Wizard of Odds and Beating Bonuses) and in the 350/350 grids of 10 Nov 2026.
One-deck charts have composition-dependent 12s against other upcards (for example 4,8 vs 3 and 5,7 vs 3 prefer stand, and those two-card exceptions were verified on 10 Nov 2026), but the frequency-weighted 12 vs 3 cell remains a hit.
Stand begins at a dealer 4 on the total-dependent chart (with the 10,2 exception described on exact-card plays). Do not carry that stand back onto a dealer 3.
