There are about 400 commonly played positions in openings that lead to certain
disaster.

Almost every EPD test suite is full of bugs.

None yet.  That would take someone who knows something about chess.  I am hoping
that some very intelligent chess player who actually knows how to play the game
will look at the data and abstract something from it.  Eventually, I will try my
hand at real study.  Unfortunately, I'm a chess dunce.

I will suggest that if you have not already done so, you should get a copy of
CDB from Peter Klausler.
His home page:

The CDB home page:
http://reality.sgi.com/pmk_craypark/cdb.html

There are CDB database files in each of those directories which are merged PGN
and EPD analysis.  There is some small problem with CDB such that about 5% of
the EPD rows will not import.  But you can see most of the results visually.

If you have a large amount of data you would like to examine, then CDB is not
currently a good solution, because it is incredibly memory intensive.  For such
installations, I would suggest getting the latest copy of Chess Assistant, which
has some built in features for viewing C.A.P. data.
