  Hi Bruce,

  According to my experience in chess world, there aren't many of those long
streets. Millions of different ways can take you to completely different
positions.
  Even if you can fix a permanent weakness (though I don't think a 30-ply
program would allow it), and after some moves the program could see it's going
to lose material (say a pawn), there should be so many different and complicated
ways to go to there, that the program would very probably lead you to tactical
territory, where you wouldn't have a chance.
  That's just my opinion...
