I'd like to know,too
analysis, help???

Oh dear.... another problem...
For some stupid reason when I go to select "Analysis Mode" it's greyed out. Why?
EDIT: Problem solved. Ok new question I'm in Winboard and in the Engine Output window, it gives a whole bunch of possible moves in lines like this:

What do those columns mean?
Ok, so, I'm thinking: 'everybody's into these "analysis engines" and "pgn files" these days. I'd like to "analyze" my "pgns" with a [free] "engine".'
how?
I've tried different downloads but I always get stuck on a few issues:
Which engine is the easiest engine to use?
How do I open a pgn file? (Are they normal opened by engines?)
What sorts of things can you learn from the analysis given by such engines?
Can anyone help me out?
