- Correct basic strategy is to hit 16 vs. 7,8,9,10 or A. Unless you are
- counting cards or you have "inside" information, it is best to hit. Most
- of the exceptions for card counters occur against 10 or 9 or A. It is a
- pretty rare situation that requires standing on 16 vs. dealer's 7.
-
- Look at the numbers below. If you stand with 16 vs. 7, you will lose
- on average about a half a bet. Hitting reduces your loss by about 12%
- of a bet. Either way you play it, you lose most of the time, but hitting
- will lose less money. You win *more* often by hitting, and you will
- sometimes push if you hit. If you stand, you lose more often and never
- push.

- The numbers for 16 vs. dealer 10 are closer together, as shown below,
- but the numbers still favor hitting over standing. You'd really prefer
- to surrender in this case, but surrender is much less common than the
- "dealer hits soft 17". In this situation, you win less often *and* you
- lose less often by hitting, but you push often enough to make hitting
- the best player overall.

-
- Assuming the dealer is always hiding a face card is a pretty good guide
- for making correct basic strategy decisions. Besides, if the dealer is
- showing a ten and you stand on 16, you will lose if the dealer is hiding
- 7, 8, 9, 10, or ace. Correct basic strategy plays take this into account.
- Basic strategy does not simply assume that the dealer is hiding a face
- card.

- I'd say this person probably does as well or better than you :-)
