Thanks very much for the quick and accurate answer!

I will try to get hold of both.
I expect the Compendium to contain a sort of overview of the thesis,
not a copy of the thesis, right?
Since I am interested in all details, I will probably need the thesis.

I will try to use this corresponding squares technique in Chest to
prove (sometimes) that a position is a draw, and therefore cannot be
won in any depth.  Up to now, the usual search techniques cannot do this.

For a stipulation "white plays and holds draw" I do not yet have any
method to construct a positive answer.

Of course, I do not yet know whether there will be a "practical"
implementation (practical == fast enough), but I would like to try.
