Strategy for tournaments, I think that in the initial phase we should look for good games, in my point of view we should not risk our stacks with two pairs as for example. I think at the beginning of a tournament we should get the nuts or something close to reach the middle stage.In the midseason of a tournament in my point of view we should take advantage of the opportunities to steal blinds, but for this to happen we must pay attention in SB and BB, we must observe if they are paying with any two cards, or if they are safer . When the SB and BB are safe players take advantage of stealing blinds by raising.
If players apply the call, you have to continue your strategy with a continuation bet, if there is resistance you must respect this resistance if you have not hit anything. Most of the time, your strategy in the middle phase of a tournament against insurance players will work.
In Bubble depending on your stack amount you must have differentiated strategies. If you are short stacked you should be more arround, being looser, if you have big stacks you should be as tight as possible because you already have money guaranteed.
