<Jer 20:10-13

Jeremiah said:

"I hear the whisperings of many:
'Terror on every side!
Denounce!
Let us denounce him!'
All those who were my friends are on the watch for any misstep of mine.

Perhaps he'll be trapped; then we can prevail, and take our vengeance on him.

But the LORD is with me, like a mighty champion: my persecutors will stumble, they will not triumph.

In their failure, they will be put to utter shame, to lasting, unforgettable confusion.

O LORD of hosts, you who test the just, who probe mind and heart, let me witness the vengeance you take on them, for to you, I have entrusted my cause.

Sing to the LORD,
praise the LORD,
for he has rescued the life of the poor
from the power of the wicked!">

<1 Corinthians 13

13 If I speak in the tongues of men or of angels, but do not have love, I am only a resounding gong or a clanging cymbal. 2 If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but do not have love, I am nothing. 3 If I give all I possess to the poor and give over my body to hardship that I may boast, but do not have love, I gain nothing.

4 Love is patient, love is kind. It does not envy, it does not boast, it is not proud. 5 It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. 6 Love does not delight in evil but rejoices with the truth. 7 It always protects, always trusts, always hopes, always perseveres.

8 Love never fails. But where there are prophecies, they will cease; where there are tongues, they will be stilled; where there is knowledge, it will pass away.

9 For we know only in part, and we prophesy only in part; 10 but when the complete comes, the partial will come to an end. 11 When I was a child, I spoke like a child, I thought like a child, I reasoned like a child; when I became an adult, I put an end to childish ways. 12 For now we see in a mirror, dimly, but then we will see face to face. Now I know only in part; then I will know fully, even as I have been fully known. 13 And now faith, hope, and love abide, these three; and the greatest of these is love.>

<The Promise of the Lord's Coming

The Second Letter of Peter

Chapter 3

1 This is now, beloved, the second letter I am writing to you; in them I am trying to arouse your sincere intention by reminding you

2 that you should remember the words spoken in the past by the holy prophets, and the commandment of the Lord and Savior spoken through your apostles.

3 First of all you must understand this, that in the last days scoffers will come, scoffing and indulging their own lusts

4 and saying, Where is the promise of his coming? For ever since our ancestors died, all things continue as they were from the beginning of creation!?

5 They deliberately ignore this fact, that by the word of God heavens existed long ago and an earth was formed out of water and by means of water,

6 through which the world of that time was deluged with water and perished.

7 But by the same word the present heavens and earth have been reserved for fire, being kept until the day of judgment and destruction of the godless.

8 But do not ignore this one fact, beloved, that with the Lord one day is like a thousand years, and a thousand years are like one day.

9 The Lord is not slow about his promise, as some think of slowness, but is patient with you, not wanting any to perish, but all to come to repentance.

10 But the day of the Lord will come like a thief, and then the heavens will pass away with a loud noise, and the elements will be dissolved with fire, and the earth and everything that is done on it will be disclosed.

11 Since all these things are to be dissolved in this way, what sort of persons ought you to be in leading lives of holiness and godliness,

12 waiting for and hastening the coming of the day of God, because of which the heavens will be set ablaze and dissolved, and the elements will melt with fire?

13 But, in accordance with his promise, we wait for new heavens and a new earth, where righteousness is at home.

Final Exhortation and Doxology

14 Therefore, beloved, while you are waiting for these things, strive to be found by him at peace, without spot or blemish;

15 and regard the patience of our Lord as salvation. So also our beloved brother Paul wrote to you according to the wisdom given him,

16 speaking of this as he does in all his letters. There are some things in them hard to understand, which the ignorant and unstable twist to their own destruction, as they do the other scriptures.

17 You therefore beloved, since you are forewarned, beware that you are not carried away with the error of the lawless and lose your own stability.

18 But grow in the grace and knowledge of our Lord and Savior Jesus Christ. To him be the glory both now and to the day of eternity.

Amen.>

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

<Psalm 23

The Lord is my shepherd; there is nothing I shall not want.

2 He maketh me to lie down in green pastures: he leadeth me beside the still waters.

3 He restoreth my soul: he leadeth me in the paths of righteousness for his name's sake.

4 Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me.

5 Thou preparest a table before me in the presence of mine enemies: thou anointest my head with oil; my cup runneth over.

6 Surely goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the Lord for ever.>

Chess and Things

Kibitzer's Corner
< Earlier Kibitzing  · PAGE 57 OF 200 ·  Later Kibitzing>
Jul-21-08  Ceri: Hi, zsoyd and team.

No refutation, although one way to play as White is 6. Be3 / Ng4 / Bc1 / Nf6 and then play f3 instead.

The following game MFO / Chessgames is probably flawed but interesting.

I was away for a set of moves in the
12-18 range.

Here is my first post when I was back and Black was probably already lost.

I'm pretty tired, but refreshed, after a holiday in Cuba.

We have some nice pressure and I don't know what is best for Black, but I tried a couple of lines if Black were to play Rc8 now and we have a promising attack, if we show enough patience:

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Be3 Ng4 7. Bc1 Nc6 8. h3 Nf6 9. Be3 e6 10. g4 Be7
11. g5 Nd7 12. h4 O-O 13. f4 Nxd4
14. Qxd4 b5 15. O-O-O Rb8 16. h5 b4
17. Na4 e5 18. Qd2 Bb7 19. g6 Bxe4
20. Bg2 Bf5 21. Bd5 Rc8

We defend with Bb3 and leave it to Black to come up with something:

22. Bb3 Be4 23. gxf7+ Rxf7 24. fxe5 Nxe5 25. Nb6 d5 26. Rhf1 Rxf1 27. Rxf1 Nc4 28. Bxc4 dxc4 29. Nxc8 Qxc8

More likely, from an OTB point of view, is Qa5 and Qe4, threatening Bg5:

22. Bb3 Qa5 23. fxe5 Qxe5 24. Bd4 Qe4 25. Rhg1 hxg6 26. Rde1 Qh4 27. hxg6 Bf6 28. Bf2 Qh5 29. Qxd6 and we are getting amongst them.

We also have to look at what is best (and if there are any transpositions) if Black prefers 21... Qa5 now.

Key to our thinking should be that our main threat is gxf7, not gxh7.

Cheers,

Ceri

Jul-21-08  zsoydd: .

Dear Ceri and team,

I think the Najdorf guarantees black a draw, hence I avoid 1.e4 with white.

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Be3 Ng4 7. Bc1 Nf6 is imho the best reply if black is happy with a draw.

White can now either accept the posrep or deviate from Be3 (with e.g. Be2, Bg5, f4, Bc4, g3, a4, f3, h3, Bd3, Rg1, Qf3, a3, Nb3, g4) but all these alternatives seem to be less forceful than the strongest Be3 lines for white.

best regards,
zsoyd

Jul-21-08  Ceri: Hi zsoyd.

Your cc game - Rybka doesn't shift its ideas at 32 depth:

30.01 13:35 +0.54 42.a4 Ke8 43.Be3 Kd7 44.a5 Kc8 45.Bh3+ Kb8 46.Bb6 Be8 47.Bg4 h5 48.Be6 Bf6 (121.312.984) 152 TB:4 31.01 22:07 +0.54 42.a4 Ke8 43.Be3 Kd7 44.a5 Kc8 45.Bh3+ Kb8 46.Bb6 Be8 47.Bg4 h5 48.Be6 Bf6 (193.557.954) 149 TB:5 32.01 34:21 +0.54 42.a4 Ke8 43.Be3 Kd7 44.a5 Kc8 45.Bh3+ Kb8 46.Bb6 Be8 47.Bg4 h5 48.Be6 Bf6 (302.363.388) 150 TB:7

My thought was to try to stop the Black King going Q-side with Bh3, which needs Be3 to be played first.

You then get:

1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 e5 5. Nb5 d6 6. c4 Be7 7. N1c3 a6 8. Na3 Nf6 9. Nc2 O-O 10. Bd3 Bg4 11. Qd2 Qb6 12. O-O Bd7 13. b3 Nb4 14. Na4 Bxa4 15. Qxb4 Qxb4 16. Nxb4 a5 17. Nc2 Bc6 18. f3 Nh5 19. g3 Bd8 20. Be3 Nf6 21. Na3 a4 22. b4 Be7 23. Rac1 Rfc8 24. Nb1 Bd7 25. Nc3 a3 26. Rfd1 Kh8 27. Bf1 h6 28. h4 Kg8 29. Kf2 Kh8 30. Be2 Kg8 31. Nd5 Nxd5 32. cxd5 f5 33. Rxc8+ Rxc8 34. Rc1 g5
35. Rxc8+ Bxc8 36. h5 f4 37. Bc1 fxg3+ 38. Kxg3 Bd7
39. Bxa3 Kf8 40. Bf1 Be8 41. Bc1 Bxh5 42. Be3 Ke8 43. Bh3 Bd8 44. a4 b6 45. Bd2 Ke7 46. a5 Bc7 47. a6 Bb8 48. Be3 Ba7

and I think that the position is a blocked draw.

What happened in practice?

Cheers,

Ceri

Jul-21-08  zsoydd: .

Hi Ceri,

a small hint: premature a4 closes the gates of Troia - imho white then cannot invade the black fortress any more.

Maybe you have still access to this game if it hasn't been removed from the database 'there'. It was against 'BBush..'.

The one against Mely was also interesting - why didn't I take the offered pawn in the endgame? In those times it was hard work to detect the trap, but nowadays fisheyes see the idea very quick.

Against Arkadeles -if I remember right- the opening crowbar 'f4' was a must, if I wanted to preserve my strong initiative. Don't know if engines are aware of the dynamic need of such attack positions.

Your PC is very much quicker than mine (who took 1 hour for 30 ply). Is it a 4-core?

Greetings,

zsoyd

Jul-22-08  Ceri: Hi, zsoyd.

I can't see LPC games without re-joining.

My machine is now quite old - 3 years.

It's a pre-AM2 AMD 4400 X2 but on its "quiet" Abit u-guru setting it runs at about the equivalent of 4675.

"Quiet" means that some of the fans are turned off, so there is less backround noise.

A modern laptop would be faster, I suspect.

Cheers,

Ceri

Jul-22-08  zsoydd: Hi Ceri,

if you wish, I can give you the solution of my puzzle, and also post my old games played on cw (they're in no DB so far, afaik).

another hint:
instead of 42.a4(??) try to enforce a significant transformation in the next two moves and then there is a very non intuitive bishop manouvre with the intention to create a free pawn which deflects the bK - please note that it is maybe still draw, but it looks very dangerous for black

This would be a good testpos for a 3500 ELO (otb) engine.

My old PC has damaged my hearing, therefor quietness is now my primary criteria for a new PC.

I'm just awaiting the next price decline for the new energy saving 45nm Q9450 (12 MB LC cache!) to finally buy my first new PC after 2003. With the new hardware and the new interactive analysis techniques i can do on a multi-core system I hope to improve my practical strength by an equivalent of 200 ELO

Cheers,

zsoyd

Jul-22-08  kwid: Hi All,
Good to see you working hard to forge out a winning opening line against GMAN.

Your last few posts seem off topic.
But it may help us to get a better understanding of the search depth requirement to extend our horizon.

Is this the position you are discussing?


click for larger view

Here is my assessment:

Get control over g4 and b5, force a passer, maximize the strength of our king to force zugzwang.

The positions above are my goals.
It may take more than 40 moves to get there. If it would be our game I would start working on the ways to reach the potential positions as shown above.

But we better get to more specific discussions how to deny GMAN a draw since we carry IMO a much high rating.

Jul-22-08  kwid: Sorry i forgot to mention that my first move is Be3 leading into:

Jul-22-08  zsoydd: .

Dear Kurt,

I'm not sure whether Your winning attempt would work.

If I remeber right, all these slow manouvers were easily paried by black (at least in my analysis of those days).

Then I asked myself: what if the bishop pair is halved?

btw:
I'm only waiting until the team finally stops to waste any computing or discussion time for the totally won game, and directs it's entire energy to the preparation of the next one.

Best regards,
zsoyd

Jul-22-08  kwid: Jul-22-08 < zsoydd: > < If I remember right, all these slow manouvers were easily paried by black (at least in my analysis of those days).>

Well now your are making me curious and challenged to see if my view is based on realistic expectations.
If you have a solution already worked out let's see if I can find a hole in it. It could safe me some time and a possible embarrassment.

Jul-22-08  Ceri: Hi, zsoyd and Kurt.

I am off on holiday on Sunday for most of the next 4+ weeks and I am trying to finish paintingn my utility room before I go.

Perhaps you could post the game and let me work on a refutation whilst I away?

Interesting that Kurt and I both tried Be3 first.

I agree that it seemed to me a forced White win with the White-coloured Bishops off but a way to force that was hard to spot.

Cheers,

Ceri

Jul-22-08  zsoydd: .

Dear Ceri, dear Kurt,

zsoyd - Bbush60854

1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 e5 5. Nb5 d6 6. c4 Be7 7. N1c3 a6 8. Na3 Nf6 9. Nc2 O-O 10. Bd3 Bg4 11. Qd2 Qb6 12. O-O Bd7 13. b3 Nb4 14. Na4 Bxa4 15. Qxb4 Qxb4 16. Nxb4 a5 17.

Bb6 Kd7 49. Ba5 Ke8 50. a4 bxa4 51. b5 *

and so on.

After 48. Bb6 Rybka needs 25 ply to see the light on the horizon.

This means it would need 37 ply in the original position before move 42 of white.

I know many such position types now - very useful knowledge when I play against engine assisted opponents (nearly all of them).

Best regards,
zsoyd

Jul-23-08  kwid: Jul-22-08 <zsoydd:> Yes! I did not see Kg4/Kg6/Kf7 threat together with Bb6/Ba5/a4 and the d6 pawn hangs. I thought that white had to play a4 to prevent b5 which would allow h5 and draw. Your bishop maneuver to a5 is the key which I did not see. Congratulation for your superb chess vision!
Truly a GM performance!
Jul-23-08  Ceri: Sorry, guys - I had the wrong mindset.

How to beat a computer in 2004?

So, I was trying to find best play, not how to sucker the opponent.

I ran Deep Fritz 7 = Fritz 8 to simulate Fritz 8 on a single-core machine - no twins back then.

Fritz, being stupid, exchanges on e8 as Black. Shredder 8 plays Bf6 and just avoids Be8:

Now, I reckon that my Bd8, then b6 plan, outlined in a post above, sets up a fortress if Black realises that the B exchange is futile!

Soon, we will have to start to find the weaknesses of Rybka 3, possibly running on an overclocked 8-core Skulltrail, with a brand new and constantly-updated opening book.

It was much, much easier killing Fritzi in end-games!

Cheers,

Ceri

Jul-23-08  zsoydd: .

Dear Kurt, dear Ceri,

I think the idea Ba4 is not that hard to see,once you come to the conclusion that there is no progress without bishop exchange. Another important observation is that white must delay a4 until time has come. Premature a4 only closes the q-side.

42. Bb5 Be8 seems to be the best defense. Other defenses (if I remember right) allow my pieces to infiltrate in the long run. For the details I'd have to dig in my old analysis files (many 100s).

Best Regards,
zsoyd

Jul-23-08  Ceri: Hi, zsoyd and Kurt.

My idea of defending as Black is to leave the K-side as is and play Bd8, then b6 and defy White to get through on the Q-side while the Bishop threatens f3. This, I think, ties down the White King, which zsoyd values as 4 pawns in this type of ending, I think.

Cheers,

Ceri

Jul-23-08  zanshin: <zsoydd> Thanks for the note in my forum. I gave Rybka (LK) one last chance, running it overnight at 1-PV. At 40-ply, the best it could come up with was:

<(0.54) Depth: 40 09:22:04 8987mN 42.a4 Ke8 43.Be3 Kd7 44.a5 Kc8 45.Bh3+ Kb8 46.Bd7 Bd8 47.Kg2 Ka8 48.Bb5 Kb8> (More lines in my forum)

I wonder if it will ever see anything better. I believe max ply depth is 59.

Jul-23-08  zsoydd: .

Dear <zanshin>,

Many thanks again for your new effort.

So it looks like not even 40 ply are sufficent for Rybka 2.3.2 to correctly evaluate the position and to propose the best plan.

If you want to, you could give 42. Bb5 a try and ask Rybka for the best 2 reply candidates.

Does Rybka on your fast machine see any significant improvent for Black if you backtrack my game (with ca. 3 minutes per move) starting from the end position?

Best regards,
zsoyd

p.s.
In a few months I hope to have Rybka 3 and a quadcore PC with 8 GB or more, so that I can do similar investigations on my own.

Jul-23-08  Ceri: Hi, all.

I accidentally ran Rybka 2.3.2a for 24 hours on the position reached after move 48 on my first post (where the Black Bishop is on a7 and the pawn on b6).

It reached depth 47 and could see no way through for White.

Cheers,

Ceri

Jul-23-08  kwid: If black can prevent Bb6/Ba5/a4 then it would be a draw right?

Jul-23-08  zanshin: <kwid> Just so I understand, you want me to start the analysis after <44.Kg4>, right?

First, I need to look at <zsoydd>'s request ;-)

< zanshin: <kwid> >

Thanks for your contributions.

But as Ceri already pointed out that black has Bd8/b6/Bc7/Ba7 etc and holding both bishops = Draw!

So the engines evaluations were correct in assessing the position after Bxh5 with a draw also!

Jul-23-08  zsoydd: .

Hi Kurt, Ceri, <zanshin>,

be aware that the pawn on a2 has a reserve tempo that can be very useful in zugzwang positions.

Early a4 throws away this potentially useful reserve tempo.

If black moves b6, a6 might become an interesting target for the wK.

best regards,
zsoyd

Jul-23-08  zanshin: <zsoydd> and <kwid> Do I take it then that you are both satisfied with the analysis done on this game? I have time for this now because of the status of the GMT game, so let me know if you want anything further.
Jul-23-08  kwid: Ok, let's get back on track to derail GMAN
The game below seems to be below a GM performance.
He may well prepare to discourage QI or Nimzo with his e3 approach as seen in this game below. Does anyone know at what time control this game was played?
