  We consider $SU(N)$ Yang-Mills theory with massless chiral fermions in a
complex representation of the gauge group. The main emphasis is on the
so-called hybrid psi-chi-eta model. The possible patterns of realization of the
continuous chiral flavor symmetry are discussed. We argue that the chiral
symmetry is broken in conjunction with a dynamical Higgsing of the gauge group
(complete or partial) by bi-fermion condensates. As a result a color-flavor
locked symmetry is preserved. The 't Hooft anomaly matching proceeds via
saturation of triangles by massless composite fermions or, in a mixed mode,
i.e., also by the "weakly" coupled fermions associated with dynamical
Abelianization, supplemented by a number of Nambu-Goldstone mesons.
Gauge-singlet condensates are of the multifermion type and, though it cannot be
excluded, the chiral symmetry realization via such gauge invariant condensates
is more contrived (requires a number of four-fermion condensates simultaneously
and, even so, problems remain), and less plausible. We conclude that in the
model at hand, chiral flavor symmetry implies dynamical Higgsing by bifermion
condensates.
