  [D]4B3/5K2/5P1b/2p5/2p5/1k6/8/8 w - - 0 1

  This study by Selesniew proved very difficult to the chess programs.
  For those of you who didn't follow the entire thread, here's some
  clarifications. It's white on the move to make a draw.

  1.Kg6! Bf4  [after 1.-c3 2.Kxh6 black cannot win]  2.Bf7 Kb4 3.Bxc4!! Kxc4
  and now we have the following position:


  [D]8/8/5PK1/2p5/2k2b2/8/8/8 w - - 0 1

  Around and around we go... 4.Kf5 Bd6 5.Ke6 Bf8 6.Kf7 Bh6 7.Kg6 Bf4 8.Kf5....
  Black has no choice but to follow. A sort of perpeetum mobile.
