I haven't read all responses but I def. agree with some and disagree with others. Not sure why this thread is so long tbh. It's completely read dependent on how villain plays postflop and there seems to be a billion lines they can take. Think about what they call with on the flop if you bet and how they'd play the turn when you take different lines as well as the river. Then think about how they'd play if you check flop. I'd say at microstakes it's better to check behind most of the time vs. the std "TAGs" and bet with second pair most of the time vs. fish. TAGs won't pay you off with crap and fish will. Most TAGs also won't bluff you off your hand. You can think a lot more into this and get to the exact types of lines each villain will play their range with to try and understand it better.

Btw - very rarely do you care what villain thinks you have at micros so stop balancing like a monkey. But then again, that's read specific too.
