The Toolbox: Check-Raising

As the name suggests, the move involves checking in front of an opponent or opponents in the hope that one (or more) of them makes a bet. When the action gets back to you, you raise. It's generally a good idea to be holding a very strong hand when you do, as many players like to call down check-raisers "just to see," and the increased money in the pot sometimes create situations where it becomes correct for your opponents to call with all kinds of crazy draws.
