I doubt there's a single secret to beating micros, but learning to let people give you their money certainly helps. This isn't one thing either. For instance, if you learn to spot those people who play LAG but only single-barrel when they don't hit, you can take away a lot of pots on the turn by floating them in position on the flop, or by calling with second and third pair hands you'd fold against someone tight.

Another example is the chronic over-bluffer who you can call light once you're recognized this tendency.
