as you have more big blinds you can play more
hands like small pocket pairs, suited conectors and obviously the premium hands
also you can play some Ax suited and those kind of hands trying to hit a flush and win a big pot
you can tribet more hands too, knowing that your oponents are going to raise hands like small pocket pairs and some suited conectors
as you go deeper and the blinds go up, the average will be like 20-50bbs, them you cant play those hands, the best at those stages is wait for premium hands except if you are in the button, BvB ...
So, at early stages, you have to take advantage of having a big stack and play a wide range
