I am familiar with the term and have seen this term thrown all over the forem this week. So my question is this.

2 or 3 betting is when a raise comes in thats 2 bet correct and a reraise is 3 bet. even in Nl holdem not just limit holdem

If i am correct so far what is an example of when a correct 2 or 3 bet should be used. I know i not ready to use this method but i would like to be able to understand this fundemental.

Thanks
Don
