I’ve used @bahia7’s famed Carrion Technique to great effect myself. It’s pretty good at floating upward a few positions at the end of a game. If I can reach the last three, I begin to switch over to my high aggression strategy for ≤3 opponents.
The key to our methodology is to carefully pick your spots for aggression. I named bahia’s strategy as such because like carrion birds, we wait patiently and scavenge from the dead and decaying stacks at the table.
Of further note, as @Sassy_Sarah mentioned in her post, a lot of us change gears at specific milestones in tournaments to take advantage or mitigate the disadvantages of the current phase. You can not and should not play the same way throughout the duration of a tournament. Doing so invites failure when everyone else rapidly flanks you with changes in range and aggression.
