Hard 12 vs Dealer 4: Hit or Stand?
Stand, under every common rule set.
Why stand is right
Here the line flips: against a 4, the dealer busts about 40% of the time, and that's finally enough to make standing on 12 the better play - barely. This is a razor-thin decision (the EV difference is under 2 cents per dollar), which is why you'll see charts agree on it but players argue about it forever. Trust the chart, stand, and don't sweat the losses; they were coming either way.
How the rules change the answer
This one is easy to memorize - the play doesn't change with the table rules.

|---|---|
| S17 · late surrender offered | Stand |
| S17 · no surrender | Stand |
| H17 · late surrender offered | Stand |
| H17 · no surrender | Stand |
