[Avodah] Rambam on Agunah

[Henry Topas]

I recall hearing a shiur tape many years ago which I believe was from Rabbi
Berel Wein Shlita.

Again, if my memory serves me correctly, he was discussing the Rambam's
position on Aganah.

I believe he quotes the Rambam as stating something to the effect that it
would take great courage to find Kulos to "unchain" agunos.

Does anyone in the Avodah family recall either the Rambam or the Shiur or
better yet, the correct location of such a citation and direct me to it?

Thank you,
