In Response To: Memorizing backgammon positions (Tom Keith)

I think this one is still stacked heavily in favor of the memory expert, if I understand correctly. When you mention nactation, I'm assuming that there's enough information that the memory expert can ignore the picture entirely and just furnish the nactation of the correct move. In particular, the test does not require any knowledge of the rules of backgammon, nor how backgammon moves are standardly notated, nor the correspondence between standard notation and nactation. So the main difference from my contest is that now random access is needed, rather than just sequential access. I'm not as familiar with the outer limits of memorization skill for random access, but my intuition is that the memory expert should still win handily.
