Subject: More ECM Inconsistencies (#100 - #199)

Hi all,

"DarkThought" finished its run with the original ECM at 90 sec
per position and I continue to analyse the results. In addition
to the inconsistencies already pointed out by Amir,
"DarkThought" differs on some more positions among the #100-#199
(even after 20 min analyses each).

ECM #135
original solution  = [ Nxb7 ]
"DarkThought" says = [ a5 ] hxg3 fxg3 f4 Nxb7 ... is equally good
                     (score = +1.3 after iteration #13,
                      looks like a transposition)
ECM #182
original solution  = [ Qxe3 ]
"DarkThought" says = [ Nd5 ] Nxf1 Ne7+ Rxe7 Qxe7 Ne6 Rxf1 ...
                     (score = +1.7 after iteration #12,
                      score of Qxe3 is +1.9)
ECM #196
original solution  = [ Rxd5 ]
"DarkThought" says = [ c3, Nbd4 ] are equally good
                     (score +1.1 after iteration #14, it thinks
                      Black loses the weak pawn on d5 anyway)

What do others think about these alternatives?
