I tested my program in the arasan test suite and there is an alternative solution to position number 6(It is possible that I already reported a mistake about this one because I remember a similiar position when I reported about a mistake when I think that it was not from the arasan test suite but I am not sure). [D]1n3rn1/3b4/rq1P1pkp/1p4p1/p1p1N1N1/2Q2B1P/1P3PP1/R3R1K1 w - - Nexf6+ is the solution. Latest version of movei changed its mind from Nexf6+ to Ngxf6+ and I think that the following analysis proves that Ngxf6+ also winning [Event "?"] [Site "?"] [Date "????.??.??"] [Round "?"] [White "New game"] [Black "?"] [Result "*"] [SetUp "1"] [FEN "1n3rn1/3b4/rq1P1pkp/1p4p1/p1p1N1N1/2Q2B1P/1P3PP1/R3R1K1 w - - 0 1"] [PlyCount "11"] 1.
