I frequently see a very small (0.10-0.15, i.e. 1/10th of a Pawn) difference between the 1st choice and the 10th. These positions are invariably nontactical, where a few moves might improve the position (e.g. Rfe1), while the others are just shifting the pieces randomly to similar squares (Rfd1, Rff1, etc.). It appears that the engine doesn't 'know' enough about chess to rank the moves sensibly.Mark Weekshttps://www.blogger.com/profile/10101044127493771263noreply@blogger.comtag:blogger.com,1999:blog-27359163.post-23591929486370408332009-05-01T11:27:00.000+02:002009-05-01T11:27:00.000+02:00A related question is, are there any positions com...A related question is, are there any positions computers find unclear? In the sense that either their evaluations don't settle during in analysis, but bobble either side of 0; or, whereby some computers prefer white and some black and this disagreement cannot be easily resolved.<br /><br />(I seem to recall that an older version of Fritz in some lines of the poisoned pawn (the e5 ones?) used to yo-yo its evaluations indefinitely.)Tom Chivershttps://www.blogger.com/profile/09850710685193416732noreply@blogger.com
