Abstract
We discuss QCD at nonstandard values of parameters (quark masses, vacuum angle θ, the number of colors and flavors) and/or at nonstandard physical conditions (when the system is essentially heated and/or squezed. Studying these “fairy” version of the theory provides a broader perspective and allows one to understand better the dynamics of actual QCD.
