if we were to open for $3 in a 100nl game with any hand we are calling a reraise with, but need to build a pot with preflop, that would also prefer lots of players in the pot when it makes its hand eg pp's and Axs but make it $4 with hands we fold to a reraise (AJo/KQo) and with hands that play quite well against the blinds (KTs/A9o JTs) does this help your thinking ?

Also, raising has a primary goal, to pot build, but also you are riasing to make your opponents do something else, make a mistake. How can you make a raise that forces your opponent into making a mistake.

Also, if you think of the stars games in particular (as they are tight) if you open for any raise size, how does your opponents cold calling raise change (or not change as may be the case) if you open for 3bbs or 6bbs?

There is a lot of sort of contradictory info, but basically you are looking to be 20/20 in terms of VPIP/PFR, so which type of raising makes this easier to acheive considering how your opponents will react to you being a 20/20 sort of player?
