Unlimited Hold'em tournaments! Success in tournament poker means long gaming sessions that will make you feel your limit and find out what you are capable of. Of course, this is not something that you can do every day, but sometimes knowing your limit can tell you a lot about yourself, and shed light on how you react in stressful situations. Once it becomes part of your comfort zone, it gives you a huge advantage over your opponents who are just getting such an experience. Tournament poker gives you the experience of playing in stressful situations without increasing your investment (because the longer the tournament goes, the higher the blinds become, but your risk is fixed from the very beginning of the tournament).
