Such a is counter productive. If you want to tume a evaluation routine for special FRC positions, better rely on the poaition iteself. The so called flag could vary depending on Shredders view of the game. Thus it could not be a base of such considerations. The demand in Shredder to distinguish leads to different FEN encodings of identic positions in some cases. >>This is as useless and dispensable as an attempt >>to distinguish Bavarians from Germans. > >I once met a Bavarian who became rather angry when he was introduced >as a German. ;-) That was simply an example for Chess being a superset to traditional chess and not being fully distinct. >>They don't want to see it mixed with traditional chess. > >This, however, is a view I can easily sympathize with.

This seems to be an argument, but it is not because of three reasons: a) if that was a serious problem, why has it been brought against Chess960 now and not earlier against Shuffle Chess long before? There has been series of so called pseudo FRC games from 18 castling compatible starting arrays. Even there nobody has seen such problems. But now such games will be stored using different FEN strings, depending on Shredders view, what is obscure. b) all stored traditional chess games are encoded WITHOUT any SetUp or FEN tag in PGN. Thus they are already 100% to be distinguished from games, derived from the other 959 starting arrays. There is no need for further flags. c) there hardly would be chess friends, which would examine games in PGN files without being aware, what that file would be about. If they are not knowing, what they are doing, maybe a computer would be an unmatching toy for them. Reinhard.
