advantages of waiting to see hole cards on your turn

[elevated]

When playing limit cash games what are the advantages of looking at your hole cards in turn? Does this differ in no limit hold'em or tournaments? Sometimes I like to see what I have before in order to analyze beforehand to make the best possible play.

If you have any tells, you can't give away any information about your hand before you see it.

also you can look for tells in other players and base your play on your reads.
