Hi,
My feeling is that unless a user has requested "tutoring" he should not see analysis of his moves/cubeplay during a game. (Not sure about analysis of lucky rolls.) The analysis can be done during the game if that will save time later, but the results should not be displayed to the user unless he wants them.

I do agree without hesitation on points b, c and d.
Not really on point a.
Users may want to have gnubg playing at, let's say,
World Class since nowadays
it's fast, but they may want to have the anlysis at
GrandMaster.
A slow analysis after the match is probably affordable,
but not slow play.

To me, no tutor should mean no analysis at all (neither
luck nor cubes,
in or out of the doubling window).
Thinking about all this stuff raised a few quetions/remarks
in my mind:
1. I think I've already reported this a while ago:
in the options
window (settings/options/tutor) I have a draw bug:
the frame "Tutor
decisions" is too small and/or empty. See it
here:
http://www.hiboox.fr/go/images-100/tutorbug,083b33b2d8dfb9273ce0693e94deaf29.png.html
2. Actually the whole tutor thing is in fact the union
of 2 different
things: "on the fly analysis" (decision
by decision instead of at the
end of the match), plus the warning mechanism in case
of errors (only
applicable for human players, of course).
"on the fly analysis" is, to me, a feature
by itself: it slows a bit
the playing pace but at the end of the game/session/match
the analysis
is already available, no wait to know your error rate.
I would go for:
1 option for "on the fly analysis"
(both players, whether gnubg or human)
Values: none /
same as eval / same as analysis
1 option for tutor (on human players)
values: warn on
doubtful / bad / very bad / never
Tutor option disabled if "on the fly analysis"
is none.
Minor remark: when "on the fly analysis"
is ON, as soon as a game (or
the entire match) is over we should have all the stats
just like if an
entire analysis is run: per game (and per match, if
over) totals, error
rates etc. If "on the fly analysis" is ON,
there should be no need to
(re)analyze the match/session/game again.
3. A final word about terminolgy: currently it's a
bit misleading.
The "Evaluation" settings act on the Hint
command.
My proposed "on the fly analysis" option
can be set as "same as Analysis"
or "same as Evaluation". Weird.
I would do the following:
- rename the current "Settings/Evaluation"
to "Settings/Hint"
- rename my "on the fly analysis" as "on
the fly evaluation", with possible
values none / same as hint / same as analysis
MaX.
