Run a couple of amps (from a current limited power supply) through the short and
use a 5 1/2 digit voltmeter on the millivolt range  and you can get the short
circuit location fairly easily.

I've hardly ever had a problem on 2-sided, and they are easy to spot
visually
and fix in a moment.  But, major trouble deep inside a 6-layer board will
drive you nuts!  Locating the exact point where two split planes or two
power planes are shorted is a real bear!
