  We study a variant of multiple zeta values of level 2, which forms a subspace
of the space of alternating multiple zeta values. This variant, which is
regarded as the `shuffle counterpart' of Hoffman's `odd variant', exhibits nice
properties such as duality, shuffle product, parity results, etc., like
ordinary multiple zeta values. We also give some conjectures on relations
between our values, Hoffman's values, and multiple zeta values.
