as touched on, adjusting to the players behind you is important at every level...if the stacks are too deep to push but at too awkward a stage to open certain hands wide, youll just have to wait when you can afford to if the stacks/reads on players behind/tournament situation dictate. unfortunately theres no way to answer this but in the most general way, youll have to look at specific hands and situations.

at a certain point in the tourney the situation/stacks/blinds will dictate shoving or folding only...at this time you can appropriately estimate the ranges to make the decision of which hands youre going to push. Eventually, no matter how hard you find certain hands to play, learning the pushing/folding scheme will take the weapons out of their hands and leave you to exploit them with your pushing and folding appropriately.

note: this skill is learned best in STTs IMO and can be adjusted to fit mtt game factors (ex usually shoving wider bc of value of antes and payout structure)
