Subject: More ECM Inconsistencies (#001 - #099)

Hi all,

I am currently running the original ECM through "DarkThought"
with 90 sec per position. In addition to the inconsistencies
already pointed out by Amir, "DarkThought" begs to differ on
some more positions among the first 99 positions (even after
20 min analyses each).

ECM #016
original solution  = [ Rxc5 ]
"DarkThought" says = [ dxe3 ] Rxd8+ Rxd8 Bb2 Qd6 ... is equally good
                              (score = +0.4 after iteration #13)
ECM #031
original solution  = [ Nxd4 ]
"DarkThought" says = [ Rd6, Qd5, Qa6, h6, h5, Kh8 ] are equally good
                     (score = 0.8 after iteration #13)
ECM #070
original solution  = [ e4 ]
"DarkThought" says = [ Rf3 ] Kh1 g5 d4 exd4 Re6 Qg7 ...
                             (score = +1 after iteration #13,
                              g5 directly seems to be a transposition)
ECM #075
original solution  = [ Nh6 ]
"DarkThought" says = [ Qh4, g6 ] are also good
                     (score = 1.2 after iteration #13)

ECM #099
original solution  = [ Qxd5 ]
"DarkThought" says = [ b4 ] Rb5 Qxd5 Be5 Qb3 Bc6 ... is equally good
                     (changes between both with scores around +0.3)

What do others think about these alternatives?
