Embla reports some bizarre evals, by the way; e.g. a 106 cp advantage in a KRKR endgame:
Ah thank you for that!
That's a most interesting bug, and not a trivial one:

Code: Select all

folkert@msi:~/Projects/QueenBee/tags/v0.9.1_2205/trunk$ ./Embla
position fen 8/5R2/8/3K2k1/8/8/3r4/8 w - -
eval
# color: white
Total Evaluation: 0.300000 (white side)
Hmmm:

Code: Select all

./Embla
position fen 8/5R2/8/3K2k1/8/8/2r5/8 b - - 33 180
eval
# color: black
Total Evaluation: 0.060000 (white side)

Well, there is some difference between +0.06 and +1.06, where does the missing 1.00 eval come from?

Exactly my point!

This probably comes from a tt-hit so now way I can reproduce this. That sucks.
