Club guessing sequences and filters

We investigate club guessing sequences and filters. We prove that assuming V ? L. there exists a strong club guessing sequence on ?i if and only if ?i is not ineffable for every uncountable regular cardinal ju. We also prove that for every uncountable regular cardinal ju. relative to the existence of a Woodin cardinal above ?u. it is consistent that every tail club guessing ideal on ?i is precipitous. ?
