 Chess variants (10x8)

Sam has closed his piano and gone to bed ... now we can talk about the real stuff of life ... love, liberty and games such as
Janus, Capablanca Random, Embassy Chess & the odd mention of other 10x8 variants is welcome too


For posting:
- invitations to games (you can also use the New Game menu or for particular games: Janus; Capablanca Random; or Embassy)
- information about upcoming tournaments
- disussion of games (please limit this to completed games or discussion on how a game has arrived at a certain position
... speculation on who has an advantage or the benefits of potential moves is not permitted while that particular game is in progress)
- links to interesting related sites (non-promotional)

jolat: well, you could see it yourself. Whenever Smirf's evaluation gets very low compared to the previous one, there it might have been a better move. SMIRF has not been designed primarily for blitz. So it actually could find its master there. Nevertheless I wonder about the circumstances. What has been the cache size? Was the other program always running (pondering)?
P.S. when I try to reconstruct it, on my computer I set 23 sec/move to get the first two answers. Already the third one would be f5. So there must be something what slows down SMIRF at your computer. Either you have other programs running or you have set the cache size very low.

OK, below the PGN of a second second (I had not saved the
first). For this second, I reversed the colors: SMIRF has the blacks
for this game.
As for the first game, I regulated the two programs with 30 sec. per move.
I stopped the game at the 40° move because SMIRF had
already a Rook + 2 pawns in less.

I downloaded this morning the version of test of SMIRF.
To give me an idea of the level of this program, I made play SMIRF
against Zillions for the game of Janus chess with the adjustment of 30 sec. by move.
I was very surprised to note that after about the 20 first moves, Zillions had taken the advantage clearly.
Can you explain me the reasons?

pierot: You might try Grand Chess or Janus Chess. They are similiar games, though have major differences. Grand Chess uses the same pieces as Gothic Chess, but has a larger board and mobile Rooks from the beginning. Pawn promotion is different and there's no castling. Janus Chess has a piece called the Janus which identical to the Archbishop of Gothic Chess. Each player gets two Januses and is played on an 10 X 8 like Gothic Chess. There isn't ay piece like the Chancellor in Janus Chess.

I asked Fencer if he would add Embassy Chess. He said he would look into it. It is almost the same game as Gothic Chess though it is not patented. The King and Chancellors are switched in starting position. The other change is the Chancellor is named Marshall and the Archbishop is the Cardinal. Castling works the same with the King moving three squares towards the Rook. So this will have a slight difference in end position from the Gothic Chess set up since the King starts one square to the side as compared to Gothic Chess. The game was created to fix the flaws of Bird's and Capablanca's set ups using the same pieces as was Gothic Chess.

If I understood well, Gothic chess will disappear from this
site to be replaced by Capablanca Random Chess. Is this well that?
If it is the case, we will not be able to play any more Gothic chess in turn based since there will be no more site which proposes it.
I saw that there is a site to play this game on line but in what relates to me, I prefer to play in turn based.
I thus find very damage this project of suppression.

Who ever wanted to know, which Gothic Chess program might be the strongest, actually could watch a long-time fight between Gothic Vortex Gold and SMIRF Beta. Average thinking times are floating between 1/2 hour and several hours, thus the playing level is of course impressing. It is also interesting to see the evaluation functions differ sometimes more than one Pawn unit. You will find more on this and also interesting comments at: http://s13.invisionfree.com/Gothic_Chess_Forum/index.php

Sumerian: That seems like an accurate statement. Janus seems way too complicated for its value on the first move to be decided at this point. But I was hoping their claims would go beyond the "feels" like black is better to a respected statistical statement. Ed did a good job arguing his case on the piece placement of Bird's chess, and why his suggested improvement works better. I was hoping for something along those lines.

Subjekt: Janus Chess Asymmetry ?
In contrast to claimed unspecified advantages of Black within Janus Chess I am convinced of White being about 3/10 Pawn units ahead in its beginning. Similar statements have been done by chess players first being faced to some Chess960 / FRC starting arrays. Those statements simply reflect the absence of opening knowledge, thus merely prove to be caused by psychological effects without a real base.

For Chess there is the general idea that black has to fight (not hard) to gain equity first and then if he succeeds he can look for a win.
For Gothic Chess the same is not valid and both sides seems to have equal chances.
For Janus Ed Trice mainly and i -in a much smaller degree- have the opinion that Black has "something" better. I don't know what is this "something" but i can feel it.....Black seems to me, to have more attacking chances.....

Subjekt: Janus vs Gothic chess
I am curious on this idea that Black has an advantage in Janus. Does he also have an advantage in Gothic chess? And if only in Janus, why not in Gothic? Are these claims supported by several statistics, or between 2 people, which could be explained away simply by style. Funny enough, I know of a chess player who always loses as white but wins as black!, because she studies only black defenses. :-) In short, how do GMs fair with black gainst white in Janus. I know that Leko, Korchnoi, and Yuspov play Janus. Does anybody know how to retrieve their results? I would think that the best way to know the answer to this question is to set up 2 powerful chess engines against each other. Interestingly, this problem of the first move lives in classical chess too, and is only solved by having the players play 2 game matches. This will always solve the problem if there were ever an instance of the first move proving to be advantagous or not.

The above is much different from the:

My opinion about Janus, although as like you, i dislike this game as it is too diagonal, is that it is well balanced, even though i have the same feeling -in a much lower degree- that black has something better.....

Pythagoras:

Well, please send me your proof of the Pythagorrean Theorem, or evidence that the moon is NOT made out of green cheese.

What I stated was a belief based on my experience and I never offered anything more than that.

Mely holds close to an International Master title in chess, and is well-versed in Janus Chess also. I was down a Queen + 3 pawns vs. the Archbishop (Janus) while playing white because Black was able to run me out of good moves. It was like distance zugzwang. I was able to dispose of those pawns to get the draw, a difficult concept to realize. And, I was able to win with Black against Mely, again, a very tough competitor.

I would like to believe that never having suffered a loss in Janus while collecting a fair number of wins allows me the freedom to speculate that the game might be inherently easier to play from Black's perspective.

White is also at a disadvantage by moving first in Janus. I had a hard time drawing Mely as white, and a much easier time winning with Black. Tough to explain, but I just think white is practically in zugzwang in the beginning of the game.
