Subject: | [Bug-gnubg] Hint only uses 0-ply when importing / setting positions |

Hi there!
GNU BG seems to be using 0-ply hints when
you set positions up manually.
Steps to reproduce:
(Using GNU BG for Windows
030501)
1. Start GNUBG
2. Confirm that evaluation parameters are
set to at least world class
3. select Edit->Enter command and enter
"set matchid cInqADAAIAAA" (w/o quotes,
of course), and click OK
4. select Edit->Enter command and enter
"set board 4LsLgArgOTjAUQ" and click OK
5. Select Analyse->Hint
This is what I get:
1. Cubeful
0-ply bar/23
21/16*
MWC: 56,66%
0,483 0,094 0,003 - 0,517 0,176 0,007 0-ply cubeful [expert] 2. Cubeful 0-ply bar/20 6/4* MWC: 54,68% ( -1,98%) 0,458 0,081 0,002 - 0,542 0,234 0,012 0-ply cubeful [expert] .. etc ...
This in spite of Evaluation parameters are
clearly set to world class (and so should be using 2ply)
I have also confirmed this with SGF
position import, and by giving the commands directly to the cmdline
program.
When I play against GNUBG a select a hint
during play, it uses 2-ply, just as it should. Even weirder, if I do an
Analyse->Evaluate, it correctly uses 2-ply. Still weirder, if I start a new
game, and let the eval engine run at least once (i.e takea hint or let GNUBG
play a move) and THEN do steps 3 to 5 I get a 2-ply hint, but ONLY in the GUI
version. Starting a new game in the cmdline version and then doing 3-5 still
produces a 0-ply hint.
What am I doing wrong here?
be well
