Composure after firing large bet

[jdeane]

Long time reader, first time poster.

I am a typical ½ NL live/online player.

This applies to both cash games and tournaments.

When putting out a large / all-in bets on any street I have always subscribed to the “don’t move at all” strategy in order not to give off any physical tells.

1) Do you think that is a good strategy?
2) Are there subtle things one can do in this position to induce or discourage a call?
3) Are there any other ways to handle yourself after you fire the bet that may be better than sitting there like a rock?

Thanks in advance for the help.
