Keeping in mind statistical variance and the fact that these are 1 cpu results, it seems to be superior to Stockfish

Hi,
recently I answered a lot of questions about why Critter gives a too high or too low score in a given position. Why not ask the engine itself? Wink
Every version of Critter has a built-in undocumented command for displaying a summary of evaluation terms.
Just run the engine in console mode and type something like this:
Code:
position fen r3r1k1/1bqn1pp1/p1pb3p/3p4/Pp1P4/1P1NPN1P/1BR2PP1/1QR3K1 w - -
eval
Answer from the engine will look like this:
Code:
| Score | White Mg Eg | Black Mg Eg
-------------+-------+---------------------+--------------------
material | -0.13 |+32.19 +31.21 +40.88 |-32.33 -31.36 -40.93
pawn | +0.33 | -0.44 -0.40 -0.83 | +0.78 +0.76 +1.02
knight | +0.45 | +0.56 +0.57 +0.46 | -0.10 -0.10 -0.14
bishop | -0.01 | -0.11 -0.11 -0.13 | +0.10 +0.09 +0.16
rook | +0.11 | +0.50 +0.50 +0.57 | -0.39 -0.37 -0.52

passed pawns | +0.00 | +0.00 +0.00 +0.00 | +0.00 +0.00 +0.00
development | -0.01 | +0.13 +0.15 +0.00 | -0.15 -0.17 +0.00
-------------+-------+---------------------+--------------------
total | +0.56 |+33.11 +32.29 +40.39 |-32.55 -31.71 -39.98
mtrl bonus | -0.52 |
final score | +0.03 | (Mg: 89% , Eg: 11%)
All scores are from whites perspective.
In some endgames (e.g. 8/5KQ1/8/8/8/8/2pk4/8 w - -) it will not show this table, just the final score and a message saying "evaluated by endgame knowledge"
Hope this will be useful.
Richard
