 | | kutztown46: <RV>, Once again, I seem to have missed the mark with the forum assignments. It is a great asset to have nine people willing for me to assign them forums, but my challenge is to anticipate where the team's interest will be ahead of time, so when it is time to change forums, we can "hit the ground running". Let's take our present situation with 36. Qf3. Last week, during the extension, I developed a forum reorganization plan for 10 different white 36th moves, including 36. Qf3. When I do this, I go as deep as I reasonably can with Fritz 9 which is usually 20 or 21-ply. For 36. Qf3, the top five black moves (at 20-ply) were Rd8 (-1.39), Qg6 (-1.07), Qxf3 (-.83), g5 (-.68) and Qg5 (-.60). After that, it dropped way off. Not having deep ply analysis from you available at the time, I made my plan as follows: 4 forums for Rd8 (assuming it would be the favorite), 2 for Qg6, 2 for Qxf3 and the last one for g5 and others. Then, once we got Yury's move, there was an immediate stampede to Qg6 and almost no interest in anything else. Then today I saw your latest analysis, with a surprising superiority of Qg6. Had I anticipated that, I would have dedicated at least 6 of the 9 forums to Qg6. So I don't know if there is anything more you can do to help me, but when white is on move, if you can pick the three most likely white moves and run an analysis showing the top four or five moves for black, assuming that particular white move is played, that would be extremely helpful to me, and I could rely less on my lower-ply Fritz analyses. Thanks! |

 | | Tabanus: <kutztown46: if you can pick the three most likely white moves and run an analysis showing the top four or five moves for black> That would be *three* separate analyses, one for each of the three white moves. <RV>, I guess this is too much since your engines are occupied with other tasks. I really like kutztown's forum organization and would like to help. But how? I'm unable to run three different high-ply's before every white move. I suggest the following: Make *6* forums each time (not 8), and assign the two last forums later after white has made his move and the situation is clearer. |

I think we all got caught off-guard by Qf3 - it just seems to lose for white. I think that things will be a bit easier from here on out because Black has realistic winning chances. |

 | | noctiferus: Hi,RV.
Sorry to post something out of theme here, but Vas asked his Rybka-friends to spread this message: it's up to you to decide if it can be posted in the main forum:"Hi,
I'm making a $100,000 challenge to FIDE President Kirsan N. Ilyumzhinov, for a match between Rybka and the winner of the upcoming "Ultimate Computer Chess Challenge 2007", which is being organized by FIDE.
Details here:

It would be great if any of you could help in publicizing this.
Thanks Vas |

<Main line: 37.Qd1 Kh8 38.Kh2 Rf8> The third line is:
<3. (-2.09): 39.Bxd4 Rd8 40.f3> I can't find the next moves in the above line which would give us such an advantage. Could you help me here?
What is Rybka's continuation? |
|
May-31-07
| | RandomVisitor: <imag>After 39.Bxd4 Rd8 40.f3 probably 40...Qh5 41.Kh1 Bxh3 42.Bxh3 Qxh3+ 43.Kg1 Qg3+ 44.Kh1 Rf8 or something like that... |

 | | amadeus: RV, does Rybka's 2.3 randomizer provide a better evaluation of a move in an endgame than its usual algorithm? Sometimes the engine seems totally lost. |
|
Jun-01-07
 | | truefriends: <RV> How you think the chances are to win this one?! I think 60% for a black win, 39% for a draw and 1% for a white win :) |
|
Jun-01-07
| | RandomVisitor: <truefriends>That's a fair estimate. <amadeus> the Rybka randomizer is likely no help here. White's drawing chances depend on deep searches into specific variations, something the randomizer does not do well. |

| Jun-01-07 | | child in time: I don't know whether it's important but I've noticed that boards (in diagrams) are flipped upside down. So, if someone not very good at chess will have problems trying to play out king form b2 to h8. Just wanted to point that out... Cheers... |
|
Jun-01-07
| | RandomVisitor: <child in time>Thanks for pointing that out. I spent some time at the start of the game deciding whether I would show the diagrams from Black's or White's point of view. There were arguments for both sides. I now see the extra problems with presenting the board from Black's perspective, and probably will do it the other way next time. |

 | | Gypsy: <RandomVisitor> I for one like the Black-point-of-view diagrams. That is the side we play for and these are our diagrams... Can not quite verbalize it, but it adds to the sense of camaraderie, sense of the team. |

| | chancho: <RV> Thanks for responding to my post. |
|
Jun-02-07
| | imag: <RV> I see that after : 37...Kh8 38.Kh2 Rf8 39.Qe1
Rybka suggests 39...Rd8. I think it would be nice to see how 39...d3 is scored. It might be slightly inferior to Rd8, but it's more forcing move. Could you maybe run an analysis of 39...d3? |
|
Jun-03-07
| | chancho: <RV> is this line 37...Kh8 38.Kh2 Bf5 39.Rf4 <Rc2> 40.Qf3 Nd2 any good? |
|
Jun-03-07
| | chancho: <RV> Forget about my question to the above line. <Boomie> pointed out what was wrong with it. |
