Hello James, I expect it is the expected results. >In the Nunn2 test positions they are all listed with "line". Yes and according to GM Nunn, those positions are from a practical games where one side's winning frequency is not greater than 60-40. I still guess that one side has the upper hand but only minimal, but of course it is interesting, maybe engines will be able to find a promising plan/novelties through continuous test and learning, like the following position from a game Chess Tiger 14-Junior 7, from OP 2002 published by Kurt. Chess Tiger here played Bc1, which I think is a novelty, more common here is Bf2 with queenside play to follow. [D]r1bqnrk1/ppp1n1bp/3p2p1/3Pp3/2P1Pp2/2N1BP2/PP2B1PP/R2QNRK1 w - - 0 12 Is Bc1 reasonable? now look what happened to the game, is that line playable against a human opponent? >If in the first case they are not expected results and they are considered equal >positions I guess they should all show "line" as a result.
