Here is my advice.
1. All previous strategiies calling in position reading players with good hands.
2. THe main thing you have to change your strategy during tournaments phase.
a. Early stage you have to very tight
b. Mid phase also should play tight but no very tight.
c. Final phase you have to open more open wide and try to play with some kind of intuition and getting to steal blinds cause you have to also know your opponents fortune, when who gets what , if in table long time was not shown best pockets AA, KK, QQ, be care of it soon it will comes after you so play safely in every stage of the Tourney and also luck is cruical and you have to be calm in every stage. The best strategy is to analyze your opponents and know the aproximate time of your fortune and opponets fortune also count than you can reach the best place! IN my oppiion, also need to count approximation of fortune !
