I grabbed this from SVN and compiled it. I tried annotating with with
both Stockfish an Crafty.
Stockfish UCI
-------------
Annotation appears to function as designed when "Annotate all moves" is
enabled.
Crafty 23.1
-----------
About every other time I start a Crafty analysis, the annotation text
doesn't show the score, instead it just shows an Mx value (e.g. M1,
M6, ...etc). However it does this in non-mating positions. For example,
it indicates all moved it's suggesting are "M1" moves. Here is an
example:
1.e4=
Crafty v23.1:14:M1
(14:M1 1.Nf3 Nc6 2.Nc3 Nf6 3.e4 e5 4.Bb5 Bb4)
So this is obviously not a mate situation. Once it starts doing this, if
I exit SCID and restart it, the issue is usually resolved, but sometimes
I have to exit and restart a couple of times.
Another strange behavior is that sometimes it's suggesting moves that
actually have a score *lower* that it's analysis of the move that was
actually mode. For example it suggests a line that is +3.2 when it's
evaluation of the actual move that was made is +3.6.
Overall
-------
In general because the tweaking of the 327 score is so small I'm forced
to annotate all moves in order to see the improved mate lines (I think
it's set to a one "centi-pawn" penalty for each additional move when
comparing mates?).
At my level, I'm really only interested in 1+/- (or greater) score
changes. What I was hoping for was to annotate a game and have all moves
that are +/- 1 annotated, but then also all "better" mate lines (such as
a mate in 3 opportunity, when my move was a mate in 6).
Would it make sense to have a configurable value used as the amount
subtracted from the 327.50 mate score? This way I could set it to 1.00
(or match it with my threshold setting) so that shorter mates will be
annotated along with all the other moves meeting the threshold setting.
That was sort of hard to put into words, so if I've been unclear on what
I mean here, please let me know.
Thanks,
