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.

Online access:

http://chess.jaet.org

Downloads (up to 5-man endings):

http://extra.sse.reading.ac.uk/peop... (pawnless endings) http://extra.sse.reading.ac.uk/peop... (DTC endings, pawn only) http://extra.sse.reading.ac.uk/peop... (all DTZ endings)

Notes:

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.

Artsemthon: The stalemate resource 102.Kxa5! would have drawn.
 
   Jun-08-12 V Malakhov vs Kuzubov, 2009
 
Artsemthon: In the position after 81.Bxa4 White can force a winning capture on his 131st move, just in time to avoid a 50-move rule draw. 101...Kg6 would have delayed the winning capture enough to draw by the 50-move rule.
 
   Jun-08-12 W So vs Navara, 2012 (replies)
 
Artsemthon: Still a draw: 68...Kc7 69.f6 Ra8! 70.Kg3 Kd6 71.Kg4 Ke6 72.Kg5 (72.f7 Ke7 73.Kg5 Kf8) 72...Kf7.
 
   Jun-08-12 Z Stanojoski vs H Mossong, 2004
 
Artsemthon: Actually, the final position is a win just in time to avoid a 50-move rule draw: the last piece capture was on White's 85th move and White can force a capture of the knight on his 135th move.

Artsemthon: Three half points were blundered in this endgame. Firstly, Black could have won with 44...Na6 45.b5 Nb4 46.Ke4 Kf6 47.a6 Bb8! 48.Kd4 Ba7+! 49.Kc4 Nc2! 50.Kd5 Nd4! 51.Kd6 Bb6! 52.Kd5 Kf5 53.Kd6 Ke4 etc, or more easily on the previous move with the simple 43...Nd2+. Secondly, White
 
   Nov-28-11 O V Ivanov vs T Melamed, 2000
 
Artsemthon: 101...Rd6! draws, e.g. 102.Rh2+ Kg8 103.Rg2+ Kh7 104.Kf7 Rd7+!
 
   Nov-28-11 M Orsag vs P Haba, 1996
 
Artsemthon: 78.Rf8+! Nf2 79.Rg8! draws.
 
   Oct-27-11 D Boros vs Z Stupavski, 2005
 
Artsemthon: 68...Bd3?? is a terrible blunder. 68...Bb1 or 68...g5 draw easily.
