We discuss non-abelian SU(N-c) gauge theory coupled to an adjoint chir
al superfield X, and a number of fundamental chiral superfields Q(i).
Using duality, we show that turning on a superpotential W(X) = Tr Sigm
a(l=1)(k), g(l)X(l+1) leads to non-trivial long distance dynamics, a l
arge number of multicritical IR fixed points and vacua, connected to e
ach other by varying the coefficients g(l).
