General No Limit Reraising Guidelines

[Riposte]

From what I understand, general betting guidelines for NL are:
<font color="blue">
PREFLOP:
bet 3-5 times the BB, add 1xBB for each limper.....thatll be a pot sized raise
FLOP:
bet 3/4 to full pot
TURN/RIVER:
bet 1/2 pot to all in, depending on what your goal is with the bet </font>


What are some general guidelines for making reraises preflop and on the following streets? Thanks...

I think a reraise should be at least 2 times the original raise (i.e. twice a minimum raise) and three times is probably a little better.
