Neural net programs do very poorly.  I think it is because they have no temporal
insight (e.g. they see it is good to develop the queen, so they thrust it out
right away).  I think a very good application of NN to chess would be to
simplify the decision making process needed.  For instance, give the NN only a
few simple parameters:
This move has win/loss/draw value x.  It has computer eval of z.  It has GM
player choice of q.
That move has win/loss/draw value a.  It has computer eval of b.  It has GM
player choice of c.
Which move should I choose?
For a simple application such as this, I think they may have great value.  But
right now, it is asking way too much of them to play the entire game.  If we
model the way a brain works, but make it a teeny-tiny pipsqueak of a brain,
where is the benefit?  Whatever we do with it, we better not overtax it.  We
might give it a migraine.
