  There are three quarks with masses at or below the characteristic scale of
QCD dynamics: up, down and strange. However, twisted mass lattice QCD relies on
quark doublets. Various options for including three quark flavors within the
twisted mass approach are explored by studying the kaon masses, both
analytically (through chiral Lagrangians) and numerically (through lattice
simulations). Advantages and disadvantages are revealed for each ``strange and
twisted'' option.
