Query: On WZ-pairs which prove Ramanujan series   The known WZ-proofs for Ramanujan-type series related to $1/\pi$ gave us the
insight to develop a new proof strategy based on the WZ-method. Using this
approach we are able to find more generalizations and discover first WZ-proofs
for certain series of this type.
