No, "DarkThought" thinks it gets the weak pawn on d4 anyway -- until iteration #11 it also prefers Nxd4 but then fails low on it to +0.65. >>>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) > >I tend to disagree. e4 is positional, and the point is that it's >possible. It prepares a pawn storm through d5, g5 and eventually e3, but >white is not dead yet. Rf3 doesn't seem to do much. Rf3 fixes the white f-pawn on f2, thus preventing White from advancing it. "DarkThought" thinks that the E file will be opened anyway -- in its PV White plays d4 and then Black takes exd4. >>>ECM #075 >>>original solution = [ Nh6 ] >>>"DarkThought" says = [ Qh4, g6 ] are also good >>> (score = 1.2 after iteration #13) >>> > >Nh6 takes a pawn and opens up things. I am not able to look so deep at >your alternatives, but seems to me that black keeps material balance and >holds with Rd7 for both. "DarkThought" thinks it gets at least a pawn in all these cases ... =Ernst=
