A hard 16 is already in trouble. Hitting can bust it, but standing gives a dealer showing 10 a strong opportunity to finish with 17 through 21. Neither choice is attractive.
When every option is negative, the correct play is the one with the smaller expected loss.
Why the result can mislead you
If you hit and draw a 10, the hand busts immediately. That vivid result can make the decision feel wrong. If you stand and the dealer happens to bust, standing can feel correct. One result does not change the underlying comparison.
The trainer grades the choice before the next card is dealt. A losing hand can still begin with the correct decision.
The rule to remember
Against a dealer 7 through ace, hit hard 16 when surrender is unavailable. Against dealer 2 through 6, stand and let the dealer’s weaker upcard carry more of the bust risk.
If late surrender is available, the chart can change. The first Casino Strategy Trainer profile does not include surrender, so confirm the actual table rules.
