your diffuse puberty rituals of fixative proving whatever are as low as your
board-habits - why not answer to the topic questions here ? btw calling a cheater
a cheater is a definition, it's no insult either, so you better don't demand reports.
Although you have not apologized for your poor performance silly me presumed a courtesy
of leaving it behind. Of course we know why indeed you sulk about going away - it's easy chicken out from true competition. I for my part won't feel pelled to having hectic games with running rabbits - no game until licence is renewed. Due to my precious reward as serious
player

Zmenené užívateľom Caissus (12. augusta 2004, 14:36:47)
Okay something "on topic": Does anybody know or can compose a chessproblem with the new pieces?
But attention,in the literature the new pieces rook/knight and bishop/knight sometimes have other names as "chancellor" or "archbishop".
I am interested to see an othodox problem with a nice checkmate in x moves (but not from a played game!),an "helpmate" (Black moves and plays together with White with the goal to checkmate Black`s king)
or a "selfmate" (White moves and forces Black`s pieces to checkmate W`s king,although he don`t want).
I´m curious if anybody has to offer something!:-)

Walter Montego 
Subjekt: Re: Chessproblem with the new pieces
Nah, he means something that's usually over in a few moves that a person could solve as a problem. The good ones usually start with a move that is surprising or atleast not so obvious as say grabbing an unguarded piece. I remember checking them out years ago. The helpmates and selfmates I never got into much, but the regular mates in three or four were always ones to play with and even share with friends that knew how to play Chess. Gothic Chess should have many possibilities for composed problems. The newspaper here no longer has the mate problems and instead uses positions from actual games and will pose a question about what move to make at some critical juncture in the game. That's not the same thing as a Chess problem.

There's one I remember that involves a King and Rook against three Pawns and a King. I'll have to see if I can remember it and then I'll post it or ask how to post it as I don't know how to make these Chess board like you guys do. I suppose I could just list the pieces and squares that they're on and who's turn it is and any interested person could set up the problem on their own board.

Most problems look as if the were actually played. They generally have a middle game look to them, though the one I just mentioned is an endgame kind of problem.

Subjekt: Re: Chess problem links
"S"? Der Springer? :)
"D", OK maybe Grand Dame
"L" I'll just have to memorize.
I might check it out sometime soon. I won't be able to follow the notes, but atleast I can work on the problems and then look for the solutions after words. Perhaps you can tell those guys about Gothic Chess and they might know of some problems already made.
Are they mates in two, or of variable length? Are they all mate problems, or are some of the other types mixed in?

12. augusta 2004, 19:48:15

L = Läufer D= Dame S= Springer and T = (I forgott) Turm (rook)

The second is "helpmate" and the third is "selfmate"

I don`t think that your both studies are correct.There are too many variations between the first and the last move.And if you perhaps know the four books of Andre Cheron - 1000 pages and one of the books is about queen-endings only- you can see that queen/onepawn against queenending mostly can be won if the pawn is near the promotionfield next to his own king.This position with the pawn at his startfield,the kings in two different corners should be draw.
Alike the second position:the material approximately is equal and either you can win at once by a tactical moment or - I think - you cannot force the win with this single piece.
Moreover I see in your solutions only one variation.I guess these moves are the suggestions of the "Gothic Vortex",but we know sometimes the programs have problems with some endings.Therefor I don`t trust them.
My personal opinion without complete analyzing,what would need too much time.

Subjekt: About the endgames
Caissus, I generated every mate possible with 5-piece in Gothic Chess. That is, I have the "5-piece tablebases" completed for Gothic Chess.

My solutions are not from Vortex, these are actually forced mates.

I started by identifying all checkmated positions. Then, I find all of the moves that lead to a mate in 1, a mate in 2, a mate in 3, etc.

This program ran for several months and solved all such mates.

The endgame databases will be part of the next version of Vortex so you can see for yourself.

Neat, harder than it looks. (Sam Lloyd's) I thought I'd solve it with a quick glance and a couple minutes of thought, but to no avail. Thanks Caissus. I'll check back on them eventually. Just how old is the Chancellor? 1880's? The history is a trip. Lots o' links from the site.

White to play and MATE IN 16

Perhaps this is wrong but i don't have time to check it now. It comes from a game between me and Gothic Vortex 1.0 from January. I'm white.

Vortex, as always with these kind of attacks, thinks that it's clearly winning, it has even a promoted Queen more and my Chancellor has been sacrificed, but my attack is(?) unstoppable. I had analysed this position before 5 months and with best play i found it as a Mate in 16 for white.

White to play and win!

This comes from a game of me against Taikoki. I found the move after some minutes and i had played it after spending 1-2 hours of analysis to be sure it's right. This move is not the only winning one, but it's the most spectacular and the most quick path to the win.

After black's move 24...Bxi5, i played the most spectacular move in the board but rather logical if you see carefully the position, and had an easy win. I don't know if it is a mate in X (X less than 20) since now Gothic Vortex doesn't work but it is a sure win for white.

As for the 2 games between me against Taikoki and Gothic Vortex 1.0, i just copied the first from Brainking history but i can't open the other.
Since Gothic Vortex isn't working i can't open the games i've saved to be able to convert them to a text file format. And when i open the *.gak files with notepad, i see only crapy things:)

Anyway here is the game with Taikoki:

Me Vs Taikoki (Brainking game):

1. f4 c6
2. g3 g6
3. Bg2 d5
4. d4 b6
5. e3 Ba6+
6. Kf2 Nh6
7. Af3 Bf6
8. Nj3 e6
9. i3 Be7
10. g4 f5
11. g5 Ng4+
12. Kg1 h6
13. h3 Nxi3
14. jxi3 hxg5
15. fxg5 Bxg5
16. h4 Bh6
17. Bi4 Ah7
18. Cg2 Cg7
19. Ae5 Af6
20. Axg6+ Kg8
21. Af7+ Kf8
22. Cxg7 Kxg7
23. Axe6+ Kh7
24. Ni5+ Bxi5
25. Qi6+! jxi6
26. Axf5+ Kh8?
27. Rxj8++ 1-0

And a question: At move 26 i entered a "?" for black, since with this move black loses immediately in the next move. But black is lost anyway. So an annotator has to enter a "?" or nothing, or even a "?!".

And even better is when a mate in X problem, has equal material on both sides or the side that is about to mate is inferior in the material.

"And even better is when a mate in X problem, has equal material on both sides or the side that is about to mate is inferior in the material"

No,this is not imortant - most chessproblems have unequal material! Important is the economic image of a special theme with a surprising "key move" and checkmates in different variants.
We speak here about a chessproblem,which is composed and not about a position of a played game.
