Maybe Black had better moves before but here the engines do not calculate. After the pregiven moves Shredder 9 gives this position as totally equal. Note that there are transpositions of moves. It does not really count how the final position the engines have to calculate has been reached, but that the resulting position after the pregiven line offers equal chances and this is the case here. > >>>>> >>>>>[Event "EventX"] >>>>>[Site "SiteX"] >>>>>[Date "2005.10.27"] >>>>>[Round "?"] >>>>>[White "PlayerX"] >>>>>[Black "PlayerY"] >>>>>[Result "*"] >>>>>[ECO "D30"] >>>>>[PlyCount "17"] >>>>>[EventDate "2005.??.??"] >>>>> >>>>>1. d4 d5 2. c4 c6 3. e3 Nf6 4.

Black tries a sharp move 8..h5 as long as both did not castle. Shredder 9 gives a small advantage for White after a few minutes of calculating (0.59). > > >>>>> >>>>>[Event "EventX"] >>>>>[Site "SiteX"] >>>>>[Date "2005.10.27"] >>>>>[Round "?"] >>>>>[White "PlayerY"] >>>>>[Black "PlayerX"] >>>>>[Result "*"] >>>>>[ECO "D02"] >>>>>[PlyCount "16"] >>>>>[EventDate "2005.??.??"] >>>>> >>>>>1. d4 Nf6 2. g3 d5 3.

The pregiven final position of the line is what counts.
