Re: [Bug-XBoard] [bug #47271] 50 move rule

[h . g . muller]

XBoard takes account of all that, and I have never seen it make an error.
Most engine-engine games actually last more than 50 moves. Castling can be
illegal because the King or Rook has moved (or was said in the loaded
position to have moved).

Note that 50-move draws and illegal moves can also be claimed by the
engine, or by the Internet Chess Server. So to diagnose any problem (if
there indeed is one), it would be essential to have an example of a game
where this happened, together with the exact conditions (which engine or
ICS was being used). And to know what version of XBoard you were using.
