preflop raising frequency

[tommo]

I'm teaching a new player how to play and finding it hard to exactly iterate what my thinking is in some places.

right now he wants to know how I decide my betting frequency preflop. So I told him to consider the following:

A. if there a raiser
1. What is your position on the raiser
2. How tight is the raiser (how often does he raise)?
3. is the raiser loose tight aggressive passive postflop

B. No raiser
1. position
2. how many callers
3. how many players left to act (and their relative tightness).
4. relative tightness of the table


What other kinds of things do you guys consider? And I'm also curious how you guys change your betting frequency based on the above guidelines.
