I may have not been perfectly clear, but my intention was to depict an engine as
a tool that "does" a position and nothing more nothing less. As such it can be
empoyed for a variety of appications: playing games, running test positions,
overnight analysis, interactive analysis, advice, blunder check, statistical
research on GM games, hardware benchmarking, and insert_your_plan_here.

Back to Robin:

Most of the applications require extra paramaters. Obviously time control is
needed to play a game. Personality settings are useful to play a different game.
Critical positions-and-values could greatly enhance interactive analyis, if
implemented as a user controlled "learning file".

And that's where I'm back to my point: TTs do enhance analysis, but they're
unreliable. After playing back 1 move you you will immediately have a 13 ply
score on your screen, but without a PV and without 12, 11, ... ply scores. After
playing several moves back and forth you'll just have to wait and see what you
get. It can be done better and it will be done better. Until then, please enjoy
what you have right now. I think you do. :-)
