Since there is no consensus on duplication of posts, I'll drop that idea.

I love your final idea, though. At each node of the tree, if we display all the existing nodes at the next level, who created them, and then either how many downstream nodes exist on each branch or how many downstream posts exist (or both), that would be very useful information and in a sense would serve as a surrogate for valuations (usually the best moves will have the most downstream nodes and posts).

Nov-30-07  Gypsy: <kutztown46> The analysis tree proposal is pretty nifty!
Nov-30-07  MostlyAverageJoe: Hey, I don't want to be pushy, but the <Acknowledgements> section might need a minor correction.

Unless I am mistaken, the idea of doing basing the analysis tree on the Opening Explorer was proposed for the first time by myself, here: The World vs G Timmerman, 2007

If I am mistaken, then my apologies to <twinlark>.

Nov-30-07  MostlyAverageJoe: Oh, yes, <zanshin>'s comments also deserve an acknowledgment.
Nov-30-07  twinlark: <MAJ> is right, I simply backed his idea.
Nov-30-07  Boomie: I'm guessing that using the standard Java chess board for the AT will be a formible programming task. To get a glimpe of the coding, open any game, right click outside the chess board, and select View Source. Clicking on the board would have to be handled in Javascript functions similar to the OpenWin function at the top of the source code. However notice that the chess board functions aren't in the source. Rather they are contained in the board object. This implies that they would have to create a new chess board object to add these functions. I don't think that's going to happen.

The OE interface would be the best route for mapping the AT. However it, too, is an object which contains its functions. Adapting it to the AT would require creating a new OE for that pupose. This may be possible without a lot of work. The AT info would have to be stored in the CG database. The new OE would then get its data from that table. It sounds doable to me at first glance. But it may prove to be too much work for too little return to CG.

My apologies. I'll fix that when I post the proposal at cg.com.

Nov-30-07  zanshin: <kutztown46: <MAJ> My apologies. I'll fix that when I post the proposal at cg.com.>

<MAJ> I am the one who owes the apology. I pointed <kutz> to a post by <twinlark> that I believed to be the original suggestion to use the OE model. Apologies to you, <kutz> and <twinlark>.

And thanks, but no, I do not need to be in the acknowledgements.

Dec-05-07  MarkThornton: I have added some thoughts on your proposal to the chessgames.com forum. I've tried to give CG some pointers as to how they might implement your idea using software they already have. It's slightly speculative, as I don't know the internal workings of their software, but I hope it gets them thinking!

Best wishes,

Mark

Dec-05-07  MarkThornton: <kuztown46> I really think we need a forum for <20. Qxe7+ Rxe7 21. Nd4 Ne6 22. Bxe4>. It's a valid alternative to <22. Nxe6>.

I'm looking at it now. I want to give Fritz a nice deep look at the position after 21...Ne6.

Here is Fritz 10 analysis, 20-ply, after 21...Ne6:

Analysis by Fritz 10:

1. = (0.23): 22.Nxe6+ Bxe6 23.Na4 Bd7 24.b3 Rb8 25.Kf1 g5 26.f3 Nf6 27.Nc5 Be8 28.Rd4 Rb4 29.Rd2

5. = (-0.19): 22.Nxc6 Bxc6 23.Nxe4 Ba4 24.Nc3 Bxd1 25.Rxd1 Nc7 26.e3 Rd7 27.b3 Kf6 28.Rd4 Ke5

6. = (-0.20): 22.Nxe4 Nxd4 23.Rxd4 fxe4 24.b3 Ree8 25.f3 e3 26.Rc3 a4 27.b4 Rab8 28.a3 Re7

7. = (-0.20): 22.Nf3 Rb8 23.b3 Nxc3 24.Rxc3 a4 25.Ne5 axb3 26.axb3 Nd4 27.Rxd4 Rxe5 28.e3 g5 29.b4

8. ³ (-0.35): 22.Bf1 Nxd4 23.Rxd4 Kf6 24.Na4 Ke5 25.Rd3 Kd6 26.f3 Ng5 27.b3 Rb8 28.Nc5 Ne6 29.Nxd7

9. ³ (-0.37): 22.a3 Nxd4 23.Rxd4 Rb8 24.Bxe4 fxe4 25.b4 axb4 26.axb4 Bh3 27.b5 cxb5 28.Rb1 Rc8 29.Nxb5 Rc2

10. ³ (-0.41): 22.h3 Nxd4 23.Rxd4 Nxc3 24.bxc3 Rxe2 25.c4 Be6 26.cxd5 cxd5 27.a4 Ra2 28.Rc6 Re8 29.Ra6 Bg8 30.Ra7+ Kf6

22. Bxe4 is not among the top 10 moves for white. Next, I'll see if I can find out why.

The problem with 22. Bxe4 is the immediate 22...fxe4! Fritz 10, 19-ply, after 22...fxe4:

Analysis by Fritz 10:

1. ³ (-0.36): 23.f3 Nxd4 24.Rxd4 exf3 25.exf3 Rb8 26.b3 Rb4 27.Rdd1 g5 28.Na4 Rb8 29.Re1 Rbe8 30.Rxe7+

2. ³ (-0.46): 23.Nxe6+ Rxe6 24.Na4 Rf6 25.Nb6 Rd8 26.Nxd7 Rxd7 27.b3 Rb7 28.Kg2 Rb4 29.Rd2

3. ³ (-0.53): 23.Na4 Nxd4 24.Rxd4 Rf8 25.Nc5 Bh3 26.e3 Ref7 27.Rd2 Rf6 28.Nb3 a4 29.Nd4

4. ³ (-0.54): 23.b3 Nxd4 24.Rxd4 Kf6 25.f3 exf3 26.exf3 Ke5 27.Rcd1 Kd6 28.R1d2 Rae8 29.Kf2 Kc7 30.Re2

5. ³ (-0.57): 23.e3 a4 24.Nce2 Ra6 25.Rd2 Re8 26.Kg2 Nxd4 27.Nxd4 Rb6 28.f3 Kf6 29.g4 exf3+

6. ³ (-0.61): 23.f4

If you still believe 22. Bxe4 is viable, let me know, and I'll give it a forum at the next change.

In a way, I'm glad you brought this up. A deeper look after 21...Ne6 shows that 22. Nxe6+ is not obvious, as I thought. However, the alternative does not seem to be 22. Bxe4. :)

Dec-06-07  MarkThornton: This is the line that I want to explore more. Note that Fritz uses a different move order to arrive at the same position as me, after Black's 26th move:

<3. ³ (-0.53): 23.Na4 Nxd4 24.Rxd4 Rf8 25.Nc5 Bh3 26.e3 Ref7 27.Rd2 Rf6 28.Nb3 a4 29.Nd4>

Black has committed himself to lose the a-pawn, in return for a K-side attack. I agree that the attack LOOKS threatening, but I cannot find a way for Black to break through. If I am right, we may get a pawn for not very much.

Here are my specific improvements on Fritz's line:

<27. Rc2> 27...h5 28. Ra4 [The a-pawn is now at our mercy. It is too late for Black to switch to defence, e.g. 28. ...Ra8 29. Nb3 Ra7 30. Rxc6]


click for larger view

Black to move. We now have:

28...h4 29. Rxa5 hxg3 30. hxg3 Rh8 31. Ra4!


click for larger view

Black to move.

Black would love to play 31...Bg4, planning ...Bf3, but there is a tactical trick, i.e. 32. f4! exploiting the pin on the e4 pawn. This move solves all White's defensive problems, as it will be followed by Rc2-h2.

If ever the White rook is on the 4th rank, and the Bishop goes to g4, then f4 is a good move for White. And the Bishop cannot transfer to f3 too early, as then White has Ne6+. I cannot find a move order for Black that gets round these problems.

We need to go very deep in this line, to see if Black can justify the sacrifice of his a-pawn.

Dec-08-07  sentriclecub: Did we have a follow-up plan to help motivate CeeGee to adopt our plan? Have they laid out any intentions to make this for us, either this challenge or our next one?

I fear that this request on CeeGee's forum will suffer the same fate as October's post. It will just get sunk in pages of old kibitzes with no follow up.

Should I post a follow up on CeeGee's forum asking where we stand?

I counsel patience. Their response was:

<chessgames.com: <kutztown46> Thank you (and sentriclecub, and MostlyAverageJoe, and others) for that proposal--we'll go over it in detail soon when we have some free time.>

Let's take them at their word. It has not even been five full days yet. Even when they discuss it, they may wish to try to do some programming first before they give us an answer, to see how difficult it will be.

If they do not respond by the end of the month, I will post a friendly reminder.

The difference between October's post and the new proposal is that we supplied much more detail this time, and it should be obvious to them that numerous team members contributed to, and support this proposal.

I don't think they will forget about it.

I think it's beneficial if someone does it. <twinlark> did it once, as did <sentriclecub>. If you don't mind doing it once or twice per cycle, please do it.
