in tournaments the player's ability plays more ... in cash tables the variance plays a more important role I would recommend you to play sit and go micro tournaments
Cash tables play pretty GTO overall, where as tournaments or the skill that separates the best from the rest in tournaments is displayed more frequently during the mid-late stages of an MTT.
Anyone can run up a stack at a cash game and leave, anyone can run up a big stack early in an MTT, however what matters is how you use those chips once you have them as you can't just get up and cash out
