In the following position against a guest:

[D]8/8/8/8/7p/4k2P/5pK1/8 b - - 1 80

BK-Chess (Shredder) allowed a draw by repetition by 80...Ke2 81. Kh1 Ke1 82. Kh2
Ke2 83. Kh1 Ke1 84. Kh2 Ke2 85. Kh1. Supposedly it has all the 3, 4, 5 man EGTBs
as per its finger notes.


The following are the BK-Chess finger notes and the complete PGN:

 1: GOD BLESS AMERICA!!!!
 2: Log on to ICC Saturday, April 6, 2pm server time and see Deep Shredder 6
take on Russian Champion GM Sergey Volkov ina a 10 game rated 5 5 blitz match!
Deep Shredder 6, Pentium III 800mhz x 2, 512 mb RAM.  All 3,4 and 5 man
tablebases.
 3: Visit me at http://www.bkchess.com and download the FREE Chess Academy
Software
 4: Current time control accepted is 3 0.  Playing unrated with anyone
registered.  Playing rated with humans within 400 points.  Sorry, no rated games
right now with computers while I work out some bugs.
 5: No more games with unregistered players for now.  Apparently people have no
respect for finger notes and continue to play 10-20 consecutive games without
giving others a chance.  Please limit yourself to 4 consecutive games.  Thank
you!
 6: Using The Shredder Classic interface from ChessBase + Ebbi's winboard
autoadapter.  This account can only play one time control because the software
cannot detect match speed from the server.  3 0 is currently accepted.
 7: I am a staunch conservative!  Liberals BEWARE!  My program will be
especially harsh on you!
 8: To those who advocate peace:  There is no peace with people like those who
attacked us.  We are not going to bomb indiscriminantly and target civilians.
We are out for a surgical, tactical campaign to root out all terrorist networks.
 9: Bin Laden and his ilk do not want peace, they want the destruction of the
western way of life in all free nations.
