fold, limp, raise, push? what range of hands should i raise and what range of hands should i push?

edit: threw in another hand i'd like some feedback on too, thanks.

Push this.

Range depends on how tight the other players are as well as your table image.

1) Raise to 600-700
2) Push

[Melchiades]

Why do you prefer raising to 500-700 over pushing? Do you plan on folding to a push from BB getting 3:1?

[splashpot]

I plan on folding to a push from the bigstack. Which I believe is SB in that hand. And I'd be getting less than 2-1.

[Melchiades]

My mistake, I read it wrong.

First hand I might raise 600 if the blinds are tight. Otherwise I fold.

Second hand I push. You don't have a wide push range here, but TT is good here (right?). I wouldn't raise or call here.
EDIT: ooh.. its 6-handed. Easy push. /images/graemlins/smile.gif
