  Dropping player names and some positions is a nice idea - especially,
from a moral standpoint, if the collection includes a prominent notice
encouraging voluntary donations by the users to the source collection,
e.g. GoGoD.

  (A technical notice: you want info about last + second-to-last move
in the position as that's a feature that's often used in patterns.
Plus, bridging over just a 1-3 moves seems pretty easy to do by brute
force.  A better scheme might be to drop, say, a block of 20 moves
starting at move 40-80 at random.)

  I think a good question is what other uses besides learning move
patterns do people envision.
