DTC = Depth to Conversion (Mate, Capture, or Promotion)
DTZ = Depth to Zeroing Move (Mate, Capture, or Pawn Move, the definition used in the 50-move rule)
DTZ50 = Depth to Zeroing Move taking into account the 50-move rule.
For pawnless endings, DTC = DTZ.

1) The winning side may sacrifice material in order to reach a winning sub-ending (e.g. in wKc2,Qf2,Nb2,Ba3 v bKa8, White plays 1.Qa7+ to force a capture as soon as possible, even though it favors the losing side).
2) For use with chess engines: Depths reported may be after the moves, leading to strange results in some cases (e.g. with wKc2,Qe4 v bKc5,Rh7, White plays 1.Qf5+ Kb4 2.Qe4+ Kc5 etc.)
For probing, download Wilhelm 1.50: http://www.mediafire.com/?nwx3865b6.... Instructions:
1) Put all endings in the folder that Wilhelm is located in.
2) Open the program and click the "hand" button.
3) Set up the position on the board (max. 5 pieces)
4) Click the "eyeglasses" button.
5) From the drop-down menu at the lower left, select the metric (DTC or DTZ) which you have downloaded.
6) Analysis should appear. If unknown or "???" appears, make sure all relevant files are available. For example, in KRBKR if White captures to KRBK and that ending is not available, then "???" displayed. Also, if only the file with one side to move is downloaded, then unknown or "???" will appear.
