Subject: Search for a Very Special Chess Position

Help!  Help!  Help!

Does anybody know of a specific chess position which satisfies the following
criteria?  Would you please post that position here?  The more the better.

Criteria#1:  For at least one popular chess engine, the engine will, after a few
minutes, settle on one and only one move for it to make in that position and
will never change it's mind no matter how much additional time is taken.

This position should not be a theoretical forced win.  Preferably it should be a
middlegame position.

What do I want this for?

Answer:  I would like to screen out all such positions which do not also meet
the following additional criteria:

Criteria#2:  For some move, to be made by the program's opponent AFTER the
program makes it's move, the same program will then face a new position which
also meets the original criteria.

I intent to extend this process until a line, originating from the original
position, is found in which the program's responses are all completely
predictable [after allowing a few minutes for each of the program's moves].

Finally, I hope to screen out all such examples except those leading to a
theoretically won position for the program's opponent.

THE ULTIMATE INTENT IS: to prove by example that at least one such position
exists. [i.e. where, for some popular chess-playing program, a line leading to a
forced win can be demonstrated, subject to the above conditions]
