I disagree. The forced mate is shown in the line. Therefore it should be easy to only count the number of moves. I don't think that #153 is just a fancy mate announcement just to show "there is a mate!". I think Stefan, Sandro or Helmut can enlighten us. >I know Ruffian announces mate in 500 sometimes :-) The programmer just chose >some value that was close to the value representing for checkmate to represent a >mate of unknown depth. Some positions before there appeared #150 sometimes, this could be a hint. :-)
