Ok Mj well, I was asking for the average situation, its sure that I will play more agressive with bigger stack or in good position, but if you want a more precise description of what gets me confused I will give you one particular situation.

In a 10$ buy-in 6 players sit and go with 5 players left, your in a early/mid position, next to the big blind, 5-6th stage of blinds so something like 60/120, you get pocket nines. Your a bit over average money with like 2500 chips (1500 at the beginning), you have the second bigger stack at that time and your feel there is a 40 to 50% chance there will be a raise preflop with two guys low in chips there is good chances for all-in pushes. How will you play this hand?
