It is not a draw - how can a position be draw if it's not legal. That's not the
point of the post nor the position -- this position is simply handy tool for a
engine users/programmers to identify maximum search depths of other engines
where they do have the code -   The position here is totally irrelevant except
to use as tool.

For example:

Junior's max search depth is 63 ply.
Fritz's max search depth is 67 ply.
Deep Sjeng's max search depth is 32 ply ? (I'm not sure about this - could this
be afalse read)
Shredder 7.04 is 99 ply.
