  Recent developments and open issues in chiral dynamics with strange quarks
are reviewed. Topics include: Order parameters of chiral symmetry breaking, the
flavor dependence of these order parameters, speculations about the phase
structure of QCD with varying number of flavors, OZI violation and its natural
emergence in case of a small strange quark condensate, heavy kaon chiral
perturbation theory, an update on pion-pion, pion-kaon and pion-nucleon sigma
terms, the dynamics and nature of scalar mesons, the role of the scalar pion
and kaon form factors, attempts to describe some strange baryons employing
coupled channel dynamics tied to unitarity and chiral perturbation theory, and
the role of final state interactions in Goldstone boson pair production in
proton-proton collisions.
