[PokerintheI]

In a casino or underground game I call it just about every time I see it, in the hand or not. I do this primarily because it doesn't seem right to me to call people out on it sometimes, but not others. I don't want other players thinking I'm only going to point it out when it is to my advantage.

However, in my home games, where the rules are a bit more lax anyway, if some new player does this, but it was obviously his intention to raise (i.e. chips in two hands but the right comes forward faster than the left) I will usually let it go with a warning the first time.
