Title: The saturation of club guessing ideals

Abstract: I will outline the proof of the consistency that there exists a tail club guessing ideal on ω1 which is saturated but not a restriction of the non-stationary ideal. The relationship between the fully and tail club guessing ideals plays an important role in the proof. This relation will be emphasized in this talk.
