[Bug-gnubg] Tutor Cube Warning bug and Export Analysis Bug

[Ned Cross]

OS: Win ME

GNUBG: Version 0.12 Build 020930

Bug:  1) Tutor mode fails to give warning flag for re-cube when TG

      2) Export position no longer including analysis (text nor html)

 

 

1) I was playing out a midgame position from a previous match, using tutor mode with the following settings:

    Cube decisions - on

    Checker play - on

    Tutor Decisions - Same as Evaluation

    Evaluation settings - (Checker Play and Cube settings Identical) 2-ply, 6 candidates, tol. 0.110, Reduced 2-ply, cubeful checker eval.

    Warning Level - Doubtful

 

**BUG** Redoubling to 4 in the posted position provoked no warning flag from the tutor.  GNU passed, and post-game analysis flagged the recube as "bad" - an error of -0.130.

 

2) **BUG** When trying to export this position to write the bug report, neither text nor html exports would include the analysis ( my export settings do still have "output move analysis" and "output cube analysis" enabled.

 

    To generate this post, I had to "copy" the analysis from the "annotation" window after pasting the exported text position.
