Definitely. SNGs with 3 paid places is the prime example. Say you are the short stack and are already guaranteed at least 3rd place. Now the two big stacks are all-in against each other. Should you join the fray, or just wait for one to knock out the other and move up to at least 2nd by folding? I think you wait. Or maybe you are in 4th place and can move into the money by watching them knock each other out. In an MTT, unless it's the final table, I say no, you take the odds and try to make the final table rather than just limping into the money.
