Also the cost of the tournament, initial chips, if it is a Freezeout, if there is a rebuy or re-entry and how many there are, if there is an add on and its payment structure. How would you feel more comfortable and less pressured after analyzing all possible tournament structures. It is easier for some to play from early stages, another middle and others at the end. Each player has a style of play and must recognize it in order to get the most out of it.
