This doesnt really apply to tournament play...thats a different kettle of fish
With Tournament play you cant afford just to sit there and play a selection of cards that you want too due the ever increasing blinds.....
In tournament play the blinds dictate your play....
In a cash game the blinds dont change so you are free to play your own strategy as you wish with out the pressure of the increasing blinds...
In cash games you dictate your own play......
