To create some feature/personalities to be used for analyses is interesting.
Many of such 'positional' judgement is discarded because the search will give
the same result, but this doesn't help at all for analysis of your own game.

A typical cenario is that you go through your game with the engine beeing a
'master' that are looking over your shoulder and give some comment and
suggestion for moves to try.
When you do this you only give the engine 10 sec. or so to analyse, only when
you need to get more coffee it could get a minute or two.
That the engine doesn't find some deep tactics does'nt matter, more important is
that the evaluation is as correct as possible and as soon as possible so you get
a hint that you are at the right road when you try some variations.
The blunder you normaly make in the game will in almost all cases be catched by
the engine in the first 5 seconds anyway.

Another feature that help in analysis is to be able to turn off all asymetry so
that the engine can keep its hashtable between half-moves. With this you can go
back and fourt in the game/variation and the evaluation would get better and
better. This is almost a must for using an engine for endgame analysis.
