EdTrice: .. thankies sooooooooo much for inviting me in..
To all those who haven't yet.. You don't know what you are missing.. it is so kewl to be able to play this game live.. and chat live as well.. From start to finish..
This game is fairly even until move 18;when I sacrificed a Knight for 2 Pawns to relieve pressure on my Kingside. Ratings are those at the time of the game. Game:396028 Match:17050. My rating was 1592 dokesa's was 1936. I am White. 1.)Nh3 d6, 2.)i3 e5, 3.)Bi2 h6, 4.)f3 Ah7, 5.)Af2 g5, 6.)0-0 Nc6,(completes my first objective of Castling quickly by using a Gothic King's Indian set-up. Now I plan to bring pressure against his Centre to create a weakness.) 7.)Nc3 b6, 8.)d3 Bb7, 9.)e4 Bf6, 10.)g4 Cg7, 11.)Be3 Nj6,(I have some Queenside pressure verses dokesa's Kingside set-up;but there are no noticeable weaknesses so far as I can see so far.)12.)Nd5 Ne7, 13.)Nxf6 Axf6, 14.)Nj4 i5, 15.)Nh3 Qd7, 16.)d4 0-0-0?!(Seems to a strategic error;because of my Queenside pressure appears too great. Unfortunately,I can not take immediate advantaage.)17.)d5 Ba6, 18.Nxi5!?(disrupts his Kingside Pawn Formation; thus relieving some of the pressure on that side. I believe this justifies the sacrifice.) 18.)....h6xi5, 19.)Axi5 Ci6,(Now I must submit to a temporary,but fairly weak Counter Attack.) 20.)Aj4 Ci8, 21.)h4 Nh7, 22.)h5 j5, 23.b3 Rj7, 24.c4!(preparing to bring my Chancellor to the b-file via d3.)24.)....Ri7, 25.)Cd3 Ri4, 26.Ah3 Ni5?

I have a draw against Hercules Beast,a 2000+ player. These are brainking ratings. This match is a 4 win match;currently tied at 3 wins each. I do believe dokesa will win this match.
I see you connected, now just click on the TEXT "experts" and you will enter the expert room. There are no pictures outside the lobby area yet. You are almost there!
I see andreas made it in to the site, but some names on there I do not recognize. Maybe you can post your GCL names here. I take it Luke is PinkPanter then?
Uhm, I talk but I get no reply. Is this just because no-one likes to answer? Or can't they here me? It looks great, except for some java-related problems I always have.
I will be posting two interesting games on here later this evening. One I playe with ChessCarpenter, but did not record all of the moves (was providing email support to some during the time I was playing) but I just reverse-engineering the missing components and i was able to create the terminal position. Just a "fun game" but it got into a major tangle that is well worth replaying.
Another game I played today with GrosPaul that contained a very sublte, sneaky mate attempt on his part this is well worth the price of admission (free)
I think GrosPaul is Spirou here on BK. More later.
{It should be noted that this was just a casual game to initiate the game site. Rob certainly is playing these moves to demonstrate his happiness at getting the new live site in place.}
4. Cg3 Nh6
5. Nh3 Ah4
6. Cd3 Bg4!
{A very interesting position that has no 'regular chess' counterpart. The flight squares for the Queen have been exhausted. Somebody needs to tell Ed this is just a fun game, he is playing way too seriously.}
7. Qe1 Axe1

{Black takes a stab at setting up a murderous check with ...Bd3+ but it will never happen, of course.}
10. d4 Cd6

{It is hard to tell if Ed is now joining in on the 'merriment' or if he is planning something. The game is being played at a fast enough pace, about 10 seconds per move on both sides, so who knows ?}
12. g3 Ch6
13. Bxc6
{More cavalier play from Black's side of the board, for a change, and now we see White taking steps to get back into the game. Rob gains a much needed tempo, functionally trading the Bishop for the minor, but more importantly, the forced move. Everyone is expecting the immediate ...bxc6, but Ed has something else in store.}
13...Ci4?!?
{It is hard to qualify the merit of this move with an on-the-spot assesment. Of course Nxh2+ Axh2 Cxh2+ is being threatened, and even so, h2 can be defended easily enough. The game has taken on an interesting character from the guise of casual, carefree play to one of growing interest, move by move.}
14. Cf3 bxc6
15. Ng5!
{A momentum shift favoring Rob's positional merit. Of course, the threat of Nxh7+ is idle with Black's Bishop holding h7, and White has no pawns to displace it from this post. Just when you think you know what is coming next, you should be prepared for anything when sitting across the board from Ed.}
15...Nxh2+?!
16. Axh2 Cxi2!
{OK, we are both confused by this sequence of events. Trading the Knight for 2 pawns plus a trashed Kingside is not the only point to consider. White will get some counterplay, won't he?}
17. Aj3 Qd5!!
{The subtle point that is not easy to grasp. 17...Cj4 looks to hold down the fort with the threat to the Archbishop and the revelation of the Bishop to hit the Rook, but after the game Black shows an incredible line where White can draw.}
{What a fantastic combination on White's part, yet the well timed, complete retreat of the Black Bishop assures that the scales are tipped favorably to him. This has become a great boxing match!}
22. c4 Qxd5
23. Ce2! Qd3
24. Ke1! Be6!
{Rob is not relenting in the least. Hoping that Ed would trade his Queen to stop Cxe7+ was the best defensive plan for White. The task of finding ...Be6 as the interefering piece was delegated to Black.}
25. Ce4 i5!
{An odd looking move that is full of purpose. Room is made for the Black Bishop, and ...Bi7 will recover the Knight.}
{A second strong retreating move, this time by a diffrent Bishop. The Rook on a1 is now the target of the Bishop's long range rifle scope.}
31. Rb1 Bc3
32. g6! Kf8!
33. gxf7 Bxf7
34. Cf4
{Rob has a plethora of annoying moves at his disposal as he sets up a disjointed fortress position of sorts. The pieces exert strange protecting influences over one another, frustrating any attempt by White to end the game more quickly.}

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. I think it was 1 of the 5 best that I have played;and that it deserves to be remembered. I am not asking to re-instate or rate this game. I still have the printout of this game at home;as I printout and save all my games. I also presented this game with this exact same analysis on this same discussion board on 24 October 2003. Here it is: 1.)d4 e5?!(a dubious Opening for Black in Gothic Chess;since it leads to harrassment of his Chancellor by pieces of far less value;and also a lasting lead in developement by White.)2.d4xe5 Cxe5; 3.)Bf4 Cf5; 4.)Ah3!?(not the best developing square for the Archbishop;but in this case the move has the value of both protecting the Bishop at f4 and attacking the Chancellor with a weaker piece.)4.)....Ce7; 5.)g4 Nc6; 6.)Nc3 d5; 7.)Nxd5!?(He can not retake without losing Material.Ex.7.)....Cxd5;8.)Qxd5 Qxd5; 9.)Bxd5; or 7.)....Qxd5; 8.)Qxd5 Cxd5; 9.)Bxd5; in either case White is decisively in front in Material,Space,and Time.)7.)....Cd7; 8.)e4 Ne5; 9.)f3 c6; 10.)Bxe5!(Saves the Knight)10.)....Cxe5; 11.)Nf4 Qc7; 12.Af2 g5; 13.)Nd3 Ce8;(The Chancellor retreats to its original square.

Onderwerp: Re: Online Game Smirf / Gothic Inventor
Sumerian: HI Reinhard,
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!

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)?.
Onderwerp: Re: Online Game Smirf / Gothic Inventor
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:

Aangepast door SMIRF Engine (14. mei 2005, 12:01:55)
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).
Onderwerp: A small tourney! Me,Smirf and G.V.......
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......:

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).

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.
