I'm not surprised. Fritz still is a lot stronger than the Baron. The difference in HW doesn't really make up for the difference in strength, also in 'normal' games. The Baron FRC doesn't have special knowledge in evaluation for FRC games. The only FRC addition is the castling rules. There are a lot of possibilities to improve here, e.g: - The loss of castling queenside should probably be punished different when the king is on b1 then when it is on g1. Also the initial position of the bishops and queens (needing advancing of the pawns before they can develop) may have an influence on this. - Hardwired squares related to e.g. trapped bishops (on a7, h7) trapped rooks (when the king moves to f1), piece development (no knight to c3 if there are pawns on c2 and d4, and not on e4) - Piece square tables with penalties for minor pieces (and some pawns) on their original squares. So there is a lot of widespread knowledge in normal chess engines that do not apply in FRC, or should be defined differently (more generic). When engines are better adapted to FRC (perhaps the authors of Betsy and Chispa already took some measures) I expect the gap with the 'normal' chess engines to close, especially in the really weird initial positions with all major pieces on one side, e.g. NNBBRQKR. Queenside castling might be very surprising here ! bye, Richard.
