 One exception. In the rook ending - black's move - it might be useful to show
 bm, which is 1.-Rd2! The theme is about "activity in rook ending". Black draws
 with 1.-Rd2! but loses with passive move like 1.-Rb8? (guarding the b6-pawn -
 but choosing passivity.) From the games I've seen so far neither Rybka nor
 Fritz 9 or Fruit understands this.
