[Bug-gnubg] Faulty Cube Statistics - Beaver

[Ned Cross]

GNU seems to have trouble interpreting game 4 of this TMG file which contains a beaver. Move analysis gives an equity for double/take of +1.407, indicating proper cube action is double/pass.  In the game white beavered, but match statistics show a -.407 take error for black, the side that doubled (I suppose because black's response to the beaver was "take").

 

No error is shown for white, apparently because GNU does not provide analysis of beavers, however I think it should be possible to flag the beaver as an error since proper action was "drop". Perhaps this is not so simple since the filter is looking for a numeric value within the user-defined ranges for "doubtful/bad/very bad".

 

 [sidebar - on TMG "take" is the ONLY possible response to beaver, there is no option to "drop" the beaver - hence the term "eat it!" in fact seems appropriate]
