You should study FTs payout structure. Every FT is different from other. There are payjumps more valuable than others, for example if the payjump from 9th to 6th is a measly increase of 10% from eachother and the payjump from 6th to 5th is around 30%, the small and mid stacks should play considerably looser in the 10% payjump range than in the 30% payjump range.
Also, another thing to consider before playing a hand is your open raise range from every position. As the game gets short handed, you should open tighter from every position, and should defend the big blind tighter. the reason for that is that you have less antes, so stealing blinds and antes is less valuable. So, for example, your open range from the cutoff should be tighter 3-handed than 6-handed and naturally much tighter than 8-handed+, and of course, the more antes there are in the middle, the looser you should be defending the blinds and your 3-betting range.
Meaning: you should open 85s in the button 9 handed, but could fold open fold (or even limp) 85s 3 handed from the button, because there are less antes and the payjumps are steeper. Theoretically, you could add a limping strategy the shorter you get, but i didnt study that enough.
To finalize that: no matter how advanced the concept is, poker is always the same. It's all about position, stack size, value of the blinds+antes and ranges, and, in tournaments, payjumps. Never settle for easy advices like "play LAG" or "play TAG".
