Yes absolutely. Not so much deliberate missing as deciding not to make a completely makeable ball. Different from a two way shot, but you should look at two way shots that are good if you make it and safe if you miss.
One example is if one of your balls blocks a pocket for the 8 or opponent’s balls. You don’t shoot that until the end or when you are confident about running out.
It sounds like you are a newer player. Bar table 8 ball has a lot of strategy- particularly when the players aren’t run out players. There are many occasions to play safe, move your balks into better spots, tie up opponents balls etc…. There are some good books on 8 ball. Givens, Schwartz, others I think.
On a bar table there are clusters. You have to think about how to break them, leave them alone, or create them.
If you are a newer player, maybe the first guideline I’d say is to never leave yourself one of your balls and the 8. You want at least 2 of your balls on the table. This makes it harder to play safe on you and easier for you to run out. A good position and shotmaking drill is to take two balls -2 solids or two stripes- and the 8 ball and toss them randomly on the table. Take ball in hand and run the two balls then the 8. This helps 3 ball patterns in all games, but here gets you thinking of an 8 ball run out.
So for now if you can’t run out all the way, look to leave yourself with two or three balls and look for ways to play safe and move your balls into better position when doing so. Like after the break. You decide on stripes. You have an easy starter but a bad cluster. Solids are tied up. You can win games by choosing the better group of balls then playing smart. Make a couple balls then try to play a safe that opens your cluster but leaves the opponent safe or difficult.
I am no bar table monster, but when I have had modest success at 8 ball, it often comes by playing a little more strategically than the opponent. You will win more games against equal opponents and be able to make things a little tougher for better opponents.
