1) Arena sends "variant fischerandom" in WB mode.
2) In Arena UCI mode, one must analyze the FEN to notice that it is FRC.
3) SMK announces by switching on option "UCI_Chess960".
All 3 work fine in my engine.

However, in case 2, it is not always possible for engine to determine from
FEN that the game is in FRC mode. That is the problem.
"rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1" has no trace of FRC.

Best,
Matthias.
