Stand on 12–16 vs weak dealer

When you have 12–16 (a "stiff hand") and the dealer shows 2–6, the correct play is almost always stand. This feels wrong. Your 16 seems weak. But the math is brutal: the dealer must hit any hand under 17, and with a 2–6 upcard, they'll bust ~40% of the time by overshooting. If you stand, you win every time they bust — without taking any risk yourself. If you hit your 16, you bust immediately 62% of the time. That's worse than the dealer's bust rate. Don't help them. The one exception in this lesson: 12 vs 2 or 12 vs 3 — the dealer isn't weak enough there, so you hit.
