Stiff hands are like bad days. They happen and they suck and there really is not a thing you can do about them except to push on and play them out. Unless of course they are one of the four hands that you can surrender, in which case surrender and wait until the next round and hope for better cards.
So what do you do with stiff hands when you are dealt them?
Well, if it is a hard 13, 14, 15 or 16 your hitting or standing will be split in half. If the blackjack dealer is showing a 2, 3, 4, 5 or 6 you will stand. This is because it would be too easy for you to hit and bust. At least with standing you have the shot at winning if the dealer busts. But if you hit and bust then you definitely lose. But if the dealer has a 7, 8, 9, 10, king, queen, jack or Ace showing you had better hit. It is likely that they will win so what does it hurt taking a stab at improving your hand? Your odds of losing here are greater anyway.
Now if you have a hard 12 the options are a little bit different. You would still hit against a 7, 8, 9, 10, king, queen, jack or Ace; but you would also hit against a dealer 2 or 3. Because a hard 12 is still a relatively small hand, there is the chance of improving the hand so blackjack players should hit!
Above all it should be understood about stiff hands in blackjack that they are the underdog hands of the game. These blackjack hands do not have the odds with them to win. But following basic strategy and winning with one is good feeling.
