Simplify trapped rook As far as can tell, semiopenFiles are set if there is a pawn anywhere on the file. The removed condition would be true even if the pawns were very advanced, which doesn't make sense if we're looking for a trapped rook. Seems the engine fairs better with this removed. My guess s that the condition that mobility is 3 or less does this well enough. Begs the question whether this is a mobility issue alone... not sure. Should I do LTC test?
