Hi
I analyzed some chess endings and I rechead this position:
8/8/8/2p5/8/8/1kP5/3K4 w - - 0 1
The Tablebase 3.2 engine says that it i lost for white. The engine says that 1. c4 will loose in 13 moves.
But the position is a draw with 1. c4
Where can i find the Tablebase 3.3 engine and the TBAccess.dll (the new one)?
Have a good day

Re: Abnormal Behavior (Tablebase 3.2)
Hi again
I am analyzing a lot of other positions and it seems when white (or black) makes a double pawn move the analysis are completely wrong. (must be a draw but he marks lost)
4k3/4p3/4K3/8/8/8/4P3/8 w - - 0 1
8/8/8/3p4/8/5K2/k2P4/8 w - - 0 1
8/7p/8/8/6K1/8/1k5P/8 w - - 0 1
Strange behavier of the engine.
I downloaded the whole 3 and 4 pieces again, checked md5 sum, and used only them.
I didn't use 5 and 6 man to be sure there is no problem with them.
Can someone confirm this behavier of the engine tablebase.eng (3.2)?
Thanks

Re: Abnormal Behavior (Tablebase 3.2)
Can you try some different engine? I don't know what is "Tablebase 3.2" but all is working fine for me with engines like Crafty or Spike. Also you can try to analyze using "Wilhelm" software.

Re: Abnormal Behavior (Tablebase 3.2)
Hi
I tried with other engines, there seems to be no problem.
The engine i have is the tablebase.eng (i think it was on the CDs Endgame Turbo 1, I don't remember).
I only wanted to know from where this behavior is coming.
I wanted to use Fritz 10 to analyze my endgames but on the Chessbase Site they say that for use with 6 man I have to use the TBAccess.dll (seems to be Tablebase engine 3.3), but I don't know where to get it without bying Endgame Turbo 3. Is it freeware this file or not?
http://www.chessbase.de/support/support.asp?pid=645 (in german)
But tablebase.eng is a lot older. It exist since the 5 men tablebases, and I thought his analysis would be perfect, but this is not true in some cases.
If someone has tablebase.eng, can he try if this behavior is the same.
Thanks

Re: Abnormal Behavior (Tablebase 3.2)
The Tablebase 3.2 engine works fine for me under Chessbase9. In your first position it shows the draw after 1.c4.
