Thanks for the help Ed! I used "Arcivedgame" and switched it back because I got the same error! If you can send me what you posted I'll see what I did wrong. Thanks Again
Then again, all the pawns might have been easier to coordinate with 3 pieces instead of one A.
I think the Germans pronounce it "TZOOG-tsvahngk." It's a deeply intellectual phenomenon which people are much better at understanding than computers are. It most certainly deserves a different kind of name like this! The machine will be utterly incapable of "contemplating" such an oddity, while the human spirit can pause and look deeply into it, imagining the ancillary implications...
I remember that game! I thought it was going to be a draw, but then you set a trap that I didn't go for. You had a back rank mate if I attacked your knight after a check! Very clever, but seen! My passed pawn was too far advanced for you stop, so I guess you gambled on me going for the trap! Good game.
Onderwerp: Re: RE: Deciphering the database stats...
The second max_w number applies to positions with black to move and win rather than white to move and win.
The "w" does not stand for white. It means Max Win Length.
Zugzwang is when it sucks to be your move. You lose as a result of it, and could draw if your opponent was to move.
Mutual Zug is very bizzarre. In super-tough endings, your side to move wins by the narrowest of margins. If your opponent could move, he can win. In fact, if you misplay, you go from a win to a loss!
Okay muggins is now better educated, thanks, but let me clarify that the second Max_W is the number of moves for white after black has moved first and I guess, Mzugs (mutual zugzwangs - sorry, never heard the term before) are postions from which both agree that to pursue the matter is a venture into hopelessness (for one side anyway).
Max_W = maximum number of moves to win.
This is 31 moves for white.
% win = what percent of all of the white to move positions win? In this case, 66.7%
% draw = 32.4%
Ave_W = the average length of the wins for white to move. With 9.2, most are easy wins. With white having more power and the turn to move, this can be a little misleading.
The other states are for black to move. The longest win is 24 moves for the Archbishop side. This does not mean the Arch is stronger since it wins more quickly. It just means if you don't win within 24 moves, you aren't going to win.
Only 30.5% of the positions win with the Arch to move, and 59.3% are draws. The average win legnth is 16.5 moves when the Arch can move and win.
The last stat, Mzugs, is the count of mutual zugzwang positions.
Also, the group decided to make it a one-game challenge.
6 battles are ongoing:
A) bwildman (position 12) challenges clean4today (position 9)!
B) ChessCarpenter (3) challenges Oliottavio (2)!
C) MidnightMedic (17) challenges Lythande (15)!
D) MatthewHall (16) challenges Spocko (14)!
E) Nasmichael (10) challenges Fencer (7)!
F) Greenknight (8) challenges Tangram (6)! --this one is particularly important,
as the winner of this clash may face one of the top 5!
Following are some of the sites (other than those who name it in the title of the fellowship) that play Gothic Chess. If you are in regularly in contact with any of these “Big Bosses” please let them know we are working on a Gothic Chess Ladder (see the fellowship) and we would welcome their players to come and try their hands and minds there.
I collated some players names, ratings, records, and will put them at that fellowship.
If you are interested in helping manage that site, send a note my way. Thanks to Greenknight and Taikoki for their quick responses as to the possibility of a ladder.

Wow. That's great service. I really appreciate your diligence, Ed. Now I just need the time to read your answer... Let's see: 1. b8=A! Kd8 2. Kd5 Be3 3. Ke6 Bf2 4. Af4 Kc8 5. Ad6+... I'll be back in a week or two... Tell the front desk to take my messages... I'm "busy."
Ed, what is the move list for how the Archbishop can win against the Knight and Bishop? It looks like a typical draw to me, due to insufficient material advantage. The Archbishop is unable to attack the Knight with a knight move, and unable to attack the Bishop with a bishop move, while each of these pieces often protect each other while preventing the Archbishop from gaining access to otherwise vulnerable squares. The two pieces have more chances to check the enemy king because of their separate locations, but the Archbishop is more maneuverable due to its unity of location. Looks like a toss up to me!
I was data mining today and found a position where the only win is a promotion of a pawn to an Archbishop where no checks are given as a result! Promoting to a Queen would draw, a Bishop would draw, and a Chancellor/Rook/Knight promotion would all lose!
The position:
white pawn on b7
black knight on a7
black bishop on c5
black king on e7
white king on e5
1. b8=A! is the only win, and it requires a total of 181 moves.
Onderwerp: Re: Nalimov Database Standard for Gothic Chess
from 8 move finish...to 202 move finish,with wins,losses,and draws.. all posibilities.That I can understand.
Wouldnt it be safe to say,that with a human factor,most all matches could have a different outcome?Also..how many variables would there be if it were 2 humans playing,or does this take every mistake into consideration?
Onderwerp: Re: Queen + Pawn vs. Queen mates in 268
There is an easy solution to this. Ask Fencer to set up a position, suspend the 50 move rule, and play against this database. I will move for it. You can move for yourself. We play until checkmate.
Onderwerp: Re: Queen + Pawn vs. Queen mates in 268
I setup a similar position in chess:
White: King a8, Queen h2, Pawn d2
Black: King f1, Queen g7
White wins in 76 moves by playing Qf4 or Qh3! All other moves lead to the draw or loose. I get this result from Nalimov Tablebase Server
on http://www.lokasoft.nl/uk/tbweb.htm
The larger board in Gothic Chess allows the black to survive more then 3 times longer (assuming Ed's software to compute Gothic Chess tablebases doesn't have bugs).
Registered owners of Gothic Vortex will get the 4 pieces databases once they are hooked up. The 5-piece databases are 900 MB total so they cannot be included without multiple CDs are some form of compression.
Onderwerp: Re: In the Gothic_250$_Prize tournement
Point taken, I will escalate my play in this game as far as possible ... and thanks rabbit ... you obviously know my true abilities, something you have exploited already a few times LOL :)
Onderwerp: Re: In the Gothic_250$_Prize tournement
:)@ rabbitoid,if the player in section 6 does not resign the game can take a long time too.
And in section 7,I think this is the typical case for estimation.
