Now here is something interesting. Since all of the conversation that happened in the German board, I have 5 orders for Gothic Chess sets from that country alone. Usually we get 1 about every 3 days from Germany, not 5 in a 48 hour span.
So thanks guys, keep up the good work, lol.
It does not matter if a product is talked about badly or not, just if it is talked about... I keep trying to tell you that. Keep hammering away at Gothic Chess, I'll keep selling
Caissus: I went to the German board. Unfortunately for me it's all in German and I could only make out about 5% of the words. I'll just have to wait until you post something in this part of the discussion board as I don't know German. I suppose I'll gradually learn it if I read the board from time to time. I went to your Janus Chess link. From the positioning and use of buttons and windows I gathered Weiter means "Enter". I hit that button, but it was all in German when I got inside. Is there an English version of this site? I really like Janus Chess and would like to try playing it live someday.

WhisperzQ: I am not sure about the advantage discussion, but future moves discussion makes sense to avoid.
As an aside, for those of us that do not visit the game db's regularly, it may be a good idea to edit the top layout including a description of what we are allowed to discuss here and what is not allowed. Just a thought.
whatdidyousay / Grim Reaper: Yes, it is an interesting game, but as it is still in progress, please do not discuss future moves or who may have an advantage, the discussion should be limited to how the game has reasched this position (all non-complying posts will be deleted without notice).
tedbarber: I was going to send you a message, bur for some reason you have me blocked - so I'll post it here for you.
If you don't want to use one of the on-line ways to pay, BrainKing has some "representives" around the world which can accept money orders from people in their area - and which they will then turn and send the payment to Fencer.
http://www.brainking.info/payment.html - this page has the information, with Eriisa - being the one in the USA who has done this for MANY people and very trustworthy. I would suggest sending her a message here and ask her for details - where she can give you her mailing address and such.
EdTrice:I would like to upgrade my membership;and have asked many times how to do it. But,I do not use credit cards;and I do not know the value of a euro in U.S.dollars. I am also a Gothic Chess Fanatic;but certainly not in your league. I am totally unable to figure out how to upgrade;because I do not understand the method required. I would love to have it explained to me where to send the money to upgrade,the U.S. Dollar amount(not the totally unknown,to me,Euro)and where to send the dues using a U.S. money order. Since this is the only way I have of paying.
... fellowship has ammended its doctrine to also serve as the conduit for requests for live games.
This will alleviate the need to use this board for requests for live games, but at the expense of requiring membership in the fellowship. This will exclude pawns from being able to post announcements or make requests for games, but it will reduce the load on the DB here.
So, for all those who are interested, send me a request to join the fellowship, post requests for live games within the fellowship, and I will look for you all there.
One thing that is very interesting is SMIRF's handling of the opening. It "has no fear" so it plays moves that appear unusual to a human, but as it has verified with its search that material is not lost within its horizon, we (humans) have to be careful about handling these positions!
I found myself down a pawn and in a disorganized retreat, and I had to rely on "tricks" to turn things around. From this I learned a few things:
1. There are tactical opportunities in the opening that I have obviously been overlooking.
2. Just developing "for the sake of developing" is clearly not good enough. In the overall scheme of things, getting more pieces in play is the best choice over 90% of the time, but S.M.I.R.F. was able to make the most of its chances with selective deployment of its pieces.
3. Apparently strong kingside attacks can be carried out with just 2 Knights if the opponent's pawn structure surrounding the castled king has been compromised only slightly. This is something that is virtually impossible in chess that is not only possible as in our game, but could be a theme to underwrite an entire strategy. Aiming long-range pieces at the castled King while "waiting" to push pawns to release their full force (as your e3 and Ae2 moves accomplished) could be an interesting, previously untried strategical motiff.
I will have to figure out how to deal with this in my own home preparation
EdTrice: thank you for putting so much time in commenting that game. It is obviously that you are seeing the game from the viewpoint of a chess master. Thank you for that!
What I am learning from such games for sceduled modifying of the program SMIRF has been following: a) SMIRF actually seems to have no more that sort of crashing I reported during the last time - positive; b) Ed very correctly is detecting weaknesses on SMIRF's placing the pieces, thus I am very sure that some future tasks might help SMIRF a little bit: to rewrite its evaluation function focussing three points: 1) making the evaluation faster (three times seems to be realistic), 2) general review of the evaluation - especially king's safety, 3) adding a component for pieces mobility - which actually is missing.

1.d3 g5?!
The point of this unusual first move is that if 2. Bxg5? then 2...Bxb2 wins The Exchange of Rook for Bishop. If 1. d4 instead, then this ...g5 "trap" cannot be played.
2.g3 Nh6
Usually I play 2...h6 to support the over-extended g-pawn.
3.Nj3?! Nc6
S.M.I.R.F. had completed an 11-ply search and was starting on ply 12. I guess it did not like Nh3 with the idea that ...g4 could chase it.
4.c4 d6 5.Qa4
An interesting move choice by white, aimed at winning a pawn with Bxc6 bxc6 then Qxc6. I thought maybe S.M.I.R.F. is expecting ...Bd7 so I played something else to test this.
5...Bg7 6.Nc3
If 6. Bxc6 bxc6 7. Qxc6 I had planned on 7...Bd7 8. Q(g2 or h1) Af6 then castling with some compensation for the pawn.
6...Af6 7.Bxc6 bxc6 8.Ne4!
This is better than 8. Qxc6, and S.M.I.R.F. wins the weakened g-pawn now.
8...Ad4 9.Nxg5 O-O 10.h3 Bd7 11.Ni5
An interesting position. White has 2 Knights on the 5th rank (i5 and g5) and a Queen on a4, with nothing else in play. Black has all of the minors developed to good posts, and Archbishop that is a little "out there" but with excellent retreating destinations that only improve its location, and is castled. At this point I made a "strategic move" without thinking tactically at all. I played the pawn push to follow instantly, which revealed the Bishop to hit on White's Queen, and I carelessly thought "this was all that mattered." S.M.I.R.F. was able to prove me wrong.
11...c5? 12.Qd1!
What a difference seeing a move being made does for your positional clarity! The j7 pawn will now come into range of the Queen on d1. With the e-pawn push, my Archbishop must retreat, and White gains another "free move" to compound the attack against j7 by adding the White Archbishop to e2. Black needs to pull a rabbit out of the hat to get back into this game.
12...Cf6 13.e3 Ae5 14.Ae2 i6
Black's play was pretty much forced. The i-pawn push reduces the scope of the threat against j7, but it also weakens the kingside pawn structure tangibly.
15.f4
Such a move, which hits on the Archbishop, is an obvious first reaction. I did not think this was best here. I was worried about my kingside being destroyed with 15. Nxj7!? Nxj7 16. Nxi6!? hxi6 and Black would have to play very accurately to marshall the resources necessary for a satisfactory defense. I have the threat of ...Axg3+! going for me since the Chancellor in the f-file pins the pawn, but at fast time controls, I have no idea how such a line will play out.
15... Ac6
And now my Archbishop surveys the board from an excellent post.
16.g4 Nj5 17.Ag3
I remember my discussions with Reinhard about the value of his pieces. My thinking at this point: his 2 knights are strong, and the game is far from needing Rooks in open files to control the endgame. Would S.M.I.R.F. trade 2 Knights for a Rook + Pawn? I think it will, so I play...
17...Kj8 18.Nixh7+ Rxh7 19.Nxh7+Cxh7
...and I am correct. Black liquidated White's strong assets and gets an easier game. Now I can focus on setting traps.
20.Ai4 Bi5 21.Cc2
In the sum of all of my experience, I have never seen Cc2 for White or Cc7 for Black lead to "promising play". In the "old days" of the first Gothic Chess Live site, back in 2000, ChessCarpenter (Rob Colanzi) handed me my first defeat ever by forcing my Chancellor onto c2. Now, such a "general statement" as "Cc2 is bad" is of course, oversimplified, but in all of my games, I have noticed that when a Chancellor is able to be deployed to the Kingside FIRST, things always go much better for that player. By heading towards the Queenside first, the Chancellor tends to be under-utilized.
21...Ki8 22.Bd2 Nh4 23.Be1 Nxi2?! 24.Bxi5
The first part of the "trap". Black loses the Bishop for just a pawn.
24... Qh8! 25.Bj6 Cxh3!!
And now my Queen is hanging as well! Hopefully the plan is too deep for S.M.I.R.F. to see. The "patient" move 26. Qe2 is best so that if 26...Ng3+ the Bishop can still retreat and play 27. Bxg3.
26.Bxh8
S.M.I.R.F. grabs the Queen, which is hard to resist.
At one point S.M.I.R.F. ran through 18 plies of search and scored the position as a repetition draw, but the whole point of the attack was to get my Archbishop into play.
30.Bj6 Ah2+!!
The role of the Archbishop was not to just capture the Queen with ...Axd1, but worsen the position of the White King first.
Asunto: Re: Another interesting Game at GothicChessLive
Sumerian:
Thanks for the game Reinhard. It was interesting in that Black (my side) had, on the surface, what everyone would identify as a "lead in development" at first glance, yet White (S.M.I.R.F.) was uncastled with fewer pieces in play, yet stood better in my opinion (after I reviewed the game.) There were some interesting "passive sacrifices" by Black where a Bishop was left hanging "on purpose", as well as a Queen. These were more akin to "traps" rather than tactically sharp play, but again, they added to the interest of the game.

After some things have been improved at Ed Trice's server (e.g. started game notation and enabled kibitzing), Smirf's Beta BC-058 has made another approach to stand a game against the GC master. But when the remaining time was getting low, it finally was overplayed by Ed again:
Asunto: Re: A small tourney! Me,Smirf and G.V.......
Chessmaster1000:
Thanks for the notes George. I have not looked at the games yet.
Please recall version 1.0.9 is rather old. Version 1.2 is out now, and this one probes the endgame tablebases as it searches as well.
http://www.GothicChess.org/vortex.zip is the link to the one with the 3-piece tablebases. I believe you also have the version with the 4-piece tablebases.
While the match results are interesting, Version 1.0.9 is no longer being improved, and results against version 1.2 (and later) are the only ones that would be helpful.
Asunto: Re: A small tourney! Me,Smirf and G.V.......
to Chessmaster1000: End of thinking (mate found): This bug is nerving in Smirf for a while. It is somehow related to the cache usage. If you would restart Smirf (it remembers the game) within that position, the error would not be reproduced. So I am about to find that silly bug, but still have not been successful.
It is good to hear, that programs still are not unbeatable. (Nevertheless Beta BC-057 again will become about 30% stronger in short).
I played a small tournament with myself, Smirf BC-056 and Gothic Vortex 1.0.9. Each player played 2 games (1 with White, one with Black) against each other. I won both 4 games. Yeah............!
Time control was 30 seconds per move, with 64 MB hash for the engines...........
1)Me-G.V 1-0 I had a nice attack as always with many surprising sacrifices for G.V, but the damn computer resisted amazingly and managed to hold with an equal position(i think) until move 33. Then it had only one line that would hold (an easy to see-33...Qh7) but it played horribly the moves 33,34,35 and lost immediatelly............!
After the game i could not immediatelly reproduce 33...Qd8? It played the correct Qh7 2 times, then the third time, it choosed e6 and after a computer start-up it choosed the Qd8 again ?!?!?!? And when i play from move 30 all the moves, it always plays the Qd8 move.......
2)G.V-Smirf 1-0 After some logical opening Pawn and Knight moves by both players, GV played an unorthodox Knight move(7.Ni5) and Smirf replied badly (7...Bxc3?). After some developing moves in an unusual position, Smirf saw a big advantage after 18...Bxd3? but it was a huge mistake. After white castled game was already over..........G.V finished the game with a nice attack.......!
3)Smirf-Me 0-1 I gave a Pawn, Smirf's development has become slow, i gave a Rook and a Bishop for an attack and mated some moves later........I have the impression, in fact i'm sure, that Smirf could win this game.....But let me intrude in its position and win.........
4)G.V-Me 0-1 I've managed to create an invisible(for G.V) attack for the white King, which G.V allowed me to make after a long time (after the fix of the Chancellor-bug, creating such positions was very difficult)....I had to praise G.V for its move 21.Ag1! and not taking the b6-Pawn, because it felt the danger (Unfortunatelly the next 2 moves was Be3 and Bxb6 taking the Pawn and probably that was the critical mistakes)....The question of course is if Ag1 could save the game. The position is already too difficult to hold.....
5)Me-Smirf 1-0 Smirf played as always(it's much more active with Pawns and not only, at the opening from G.V) the kind of moves i hate. Pawn-attacking moves, challenging me for the center and not giving me space, and not afraid to leave hanging pieces. My nightmare......! Some strange moves by me giving 3 Pawns and then a Rook, that Smirf took instead of accepting the 3 Pawns and castling safely. Then a crazy tactical position arised. Giving my last Rook i had a nice attack but the win was not obvious....But the final winning combination was startling........! "27.Cf1! , 28.Cf5!! , 30.Nf6! was some of the good moves......."
In this game also occured the following:
I would put this to my notes for Reinhard about Smirf, but here is anyway:
In the 6th move and after my c3 Smirf had a bad(buggy?) reaction again. The position is this and Smirf's evaluation was the following......:
r1bqckab1r/pp2pp1ppp/2np2pn2/ 2p7/4PP4/2P3PP1N/PP1P4PP/RNBQCKAB1R b KQkq - 0 6
-----------------------------------------
End of thinking (mate found)
00:00.0 (06.08+) +M~254 6...Be6 (Af6)
-----------------------------------------
6)Smirf-G.V 1/2-1/2 G.V was out of book in its second only move(smirf doesn't have a book). After some unorthodox moves again by both players, i can really say that Smirf outplayed G.V at the opening in this position and reached a very favorable position. After 18...Kg7 i had the impression that Smirf would convert this winning position into a win. And at move 34 it was clear that Smirf would be able to win although the position was VERY difficult to do it. It needed a strategic plan to do it. To bring the Rooks into action and prevent the Archbishop from breaking through into white's King's position. But Smirf played the awuful Bxf4? instead of gxf4 and allowed G.V a perpetual check.........
In this game also occured the following again:
I would put this to my notes for Reinhard about Smirf, but here is anyway:
In the 33th move and after GV's 32...Ad7 Smirf had a bad(buggy?) reaction again. The position is this and Smirf's evaluation was the following......:

EdTrice: Sliding scale: In Smirf average exchange values are constant. But the positional influence will vary automatically, thus I have not to rebalance those values. When a piece is captured, the evaluation is not only reduced by the exchange value, it will be positionally recalculated.
Pawn Races: Smirf has included a simple estimation of passed pawn values - still not perfect.
Castling awareness: Castling is not individually analysed, it will be selected automatically by positional considerations only, independent e.g. from castling moves.
trying to teach Vortex: I am very distant to such approaches. Because it is nearly impossible for a chess master to describe what exactly he is doing during his considerations. I think that something like this might lead into a conceptual chaos. But why not give it a try? I am on the opposite way, trying to 'feel' the needs of a 'frustrated' and 'madly' working machine, to reduce the needs of its job (danger, could lead to paranoia).
Sumerian: Is your Gothic Vortex even still subject for improvements (beside of providing more looking-up information)?.
The evaluation function for Gothic Vortex is very primitive as well. It has a few innovations. Some of these have been around for a while, but here is what I think is unique:
1. Sliding scale weight for the "Supermajors" (Queen, Chancellor, Archbishop).
The values for these pieces are not "constant", they change during the phase of the game. The Archbishop gets weaker as the game progresses, the Chancellor gets stronger, then weaker, and the Queen slowly gets stronger.
2. Pawn Races - The program can play ANY king and pawn ending properly, even with just a 3-ply search. This makes it strong in the endgame.
3. Castling awareness - Castling is not just a "straight bonus", it evaluates whether or not the opponent is castling into danger.
I have changed the evaluation function since the 2004 Computer World Championship, but this was mostly bug fixes.
For exmaple, in some of the wins that Chessmaster emailed to me, there were obvious bugs regarding king safety that had the program think it was ahead as much as +400 when really it was -200.
I have long since fixed this bug (4 months ago) and Chessmaster1000 has not sent me any wins since that time.
I have introduced something else that might have disasterous effects, but it only an experimental version for now. I am trying to teach Vortex how to play like me. It is not easy to do! I am using some of my games on BK as an example, but no matter how long I let Vortex think, it just does not want to make sacrifices like I do.
When I figure out how to code this, I will release the new version. For now, the latest and greatest version is at:
to EdTrice:
I noticed, that the result of the game has been a welcomed satisfaction for those who are hoping that humans still might play better (Gothic) Chess than computer programs.
You know that Smirf still has a lot of weaknesses, where I have to develop against. With a 53K size of its engine there already is a lot of intelligence per byte, but it has to be enriched to finally become able to defeat your Gothic Vortex program or even a top player like you.
If you remember Smirf playing in November at your fine tournament, you definitely could notice the one or other improvement. But still e. g. the evaluation function is unchangedly weak.
The new beta BC-056 has eliminated the PGN reading bug, when comments are standing split at several lines. Also the search routine is no longer that overpruned like it partially had been in its ancestors.
Is your Gothic Vortex even still subject for improvements (beside of providing more looking-up information)?.
Thanks for playing, it was a good game. I felt that the lead changed hands a few times as we played this one.
At 8. Bxh6+ ixh6 White is better, and 9... 0-0? surely is a mistake given that the i-pawn is not there to sheleter the King. The problem is, how does one go after this weakness most efficiently?
As soon as I played 10. f4 I knew this was not the best. I block a diagonal that leads to the weakened area of your board, and I prevent my Chancellor from being able to become effective more quickly.
But SMIRF really hung in there, and even turned things around, nullifying any attempt by me to create tactical chances.
So...it was time to get strategic... what to do?
For one I had to get Archbishops off the board, my own vulnerability in the vicinity of h3 was becoming a problem that SMIRF was exploiting well. I think a timely ...Qd7 was called for, but it never happened.
15. Rb1? was a mistake by me, I should have played 15. i3 and held the pawn that dropped right afterwards.
22. Kj1? was more of a "confession" that I didn't know what to do rather than a mistake, but since we were playing quickly, I had not time to reflect. A grandmaster once said "If you do nothing, do it well!" so that is what I tried to do.
24. Rg5?!? is purely cavalier, and an attempt to complicate matters. I did not know if I was digging my own grave, but I surely had a shovel in my hand.
What happened next is entertaining, and I will let the rest of you enjoy it.
I fully expect Chessmaster1000 to tell me all the reasons why this was a bad move, because I deserve it!
White=tedbarber (Unrated) Black=Spirou (1685) Dates of Game: 7 October 2003--23 October 2003. Game #215181 This was my first win on Brainking.com. Unfortunately,it was wiped out in November 2003 by a virus;as were my first 3 completed games and 17 other games in progress.
