Hi Dann, >In order to create an accurate tactical suite, I would like to have these rows >crunched by alternative software tools. The current analysis does not get "the >right answer" so the question is, will other programs see it? Most of the positions you posted do *not* seem to be tactical but rather positional in nature (e.g. "Soszynski 80 #13" is actually from the positional subset of LCT-II). >[D]r1r3k1/5p2/p3p1p1/b6p/Pp2N3/1P2P3/5PPP/2R1K2R w K - acd 18; acn 1259897193; >ce -32; pv O-O Bd8 Rfd1 Be7 Kf1 Kf8 Ke1 f5 Ng3 Rc3 Rb1 Kf7 Ne2 Rc5 Rbc1 Rac8 >Rxc5 Bxc5 Nd4; pm O-O; bm Ke2; id "Soszynski 80 #8"; Positional -- "DarkThought WCCC'99" never chooses 0-0 as best.
