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.

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. > For the computer the following is done > before roll: > a 0-ply assessment of our position in the double window.

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. _______________________________________________ Bug-gnubg mailing list [email protected] http://lists.gnu.org/mailman/listinfo/bug-gnubg
