They have also been tested against Q (alonme or in pairs, with or without pawn odds for the latter), BNN, RR and RN (with or without Pawn odds). On the average, C does only slightly better than A, on the average 2-3%, where giving Pawn odds makes a difference of ~12%. The A-RNP result seems a statistical fluke, as it is almost the same as A-RN, while the extra Pawn obviously should help, and the A even does better there than C-RNP. Note the statistical error in 432 games is 2.2%, so that 32% of the results (so eight) should be off by more than 2.2%, and 5% (1 or 2) should be off by more than 4.5%. And A-RNP is most likely to be that latter one. Edit Form You may not post a new comment, because ItemID ARCHBISHOP Value does not match any item.
