When chiral symmetry is spontaneously broken, the low-energy part of the Dirac operator spectrum can be computed analytically in the chiral limit. The tool is effective field theory or, equivalently in this case, Random Matrix Theory.

We revisit quenched reduction with fermions and explain how some old problems can be avoided using the overlap Dirac operator.
