  [D]2r3k1/4pp1p/3p2p1/p2R4/1r6/1P4P1/P3PP1P/R5K1 b - - 0 1


  This is a position from the game IM Giardelli-GM Andersson, Argentine 2001.
  It was previously posted, with some comments, under "Testposition - Double
  Rook ending." Andersson won this game in a convincing style. Voices were
  heard that Fritz might have done better than Giardelli. That arouse my
  curiosity, so I decided to give it a go.

  PIII 800, 128Mb Hash, 3-4 and some 5 men TB:s (not KPPKR...;)
  The whole game, from the above position, in 1 hour each.
