Henry Bird Games Added to http://www.jrobichess.com

I have added the games of chess legend Henry Bird to http://www.jrobichess.com/. Bird worked full time as an accountant, yet was a brilliant chess player. He squared off against the likes of Morphy, and has a chess opening that bears his name: "The Bird's Opening" which despite repeated attempts to refute, continues to be a solid opening choice for white.

Aquarium Update 3.1.0


Patch Notes

Patch 3.1.0 Notes

Major features
* New, more convenient, 'Paint-like' way of editing color markers in the game and in the tree.
* You can read Aquarium i-Books. Editing possibilities are limited, they'll be enhanced in futher update. However, if you are not afraid of writing a Wiki-formatted text, you can edit/create new i-Books.
* You can run Game Analysis from the Sandbox.

Major bugfixes
* Fixed occasional header fields loss when pasting a game into the database game.
* 'Remove before' no longer cripples games that stared from non-initial positions.
* Randomizer match dialog is now displayed correctly.
* Engine evaluations are now printed correctly.

Minor features
* Added a popup menu for changing tree configuration in the Tree window header.
* Added possibility to view only main tree moves in a tree configuration.
* Smart Input is now 'even smarter': you can right-click (with left button pressed) to cycle through available moves.
* You can manually edit opening book play probability for each move in the tree configuration.
* You can set clocks during the game in Play mode (double-click the clocks).
* Allowed playing against Fritz via Auto232 network protocol (works OK on all our computers, but not tested much).
* Using Ctrl+move to exclude moves from infinite analysis now changes the analysis pane display.
* There is a clearer indication of which window has focus. Helps to determine whether we are browsing tree or notation.
* New feature: opponent move to limited depth. After reaching this depth the engine switches to normal analysis.
* Ribbon double-click minimization is more convenient now.
* Board sounds now active in the Sandbox and database game view.
* Export options dialog changed slightly to be more logical.
* Newly created database is added to the Recent list.
* When loading a EPD string, the leading and trailing spaces are now ignored.

Minor bugfixes
* Fixed memory leak issue in analysis chart.
* Display options dialog: checkbox for 'Show board navigation' is consistent with 'Material imbalance'.
* Fixed occasional clearance of game header by Game Analysis.
* Improved hit detection when clicking on the game flag in the games list.
* Fixed tree window reappearing after it was hidden by the user.
* Selected cell in Games list is no longer made gray.
* Ctrl+move in Two clicks input mode now works as well. If it's done during IA it excludes the move from the search, otherwise it adds a variation.
* Using Ctrl+move to exclude moves from infinite analysis works with Smart move too.
* Fixed occasional incorrect conversion of PGN NAGs to 'Long after' comments.
* Tree options dialog: advanced controls no longer peek out of the bottom of the window.
* Notation position change after switching to another application and back is partially fixed.
* 'Insert deleted moves to clipboard' option works now.
* Fixed smart move inability to drag the pointer from destination to the source square.
* Cursor is position correctly after 'Delete variation'.
* Fixed occasional mouse pointer disappearance when editing the game header.
* Analysis pane is no longer cleared when the mate score is achieved.
* Engine match view now respects board cursor settings.
* IDEA display now respects board orientation.
* Game Analysis now respects 'Show coordinates' and 'Show board navigation' settings.
* Fixed diagram display in HTML export.
* Fixed absence of sampled search display after switching to Rybka 3 from another engine.
* Fixed small bugs in tree custom coloring.
* Finished Engine Competition date is no more reported as 30/12/1899.
* Fixed some issues in CTG book handling.

What's next:
We are going to enhance the editing possibilities for Aquarium i-Books, so that you can easily write such books yourselves. This, and some more minor fixes and features, will make a 3.1.1 update.
Then it'll be time for another 'large' project. Maybe it'll be IDEA this time, but I don't know yet.

GM Igor Kurnosov (Russia) Responds to Allegations of Cheating

In the blog post "Grandmaster Accuses Fellow GM of Cheating at Tournament" we talked about GM Shakhryiar Mamedyarov's accusation that his opponent GM Igor Kurnosov cheated during their game. There has been to date absolutely no evidence to support this claim, and now Kurnosov has responded to the accusations in the following letter:

Dear Colleagues and chess lovers,

With regard to the discussions in the press of Mamedyarov's letter, I must explain the situation. I present the game Mamedyarov-Kurnosov from round six of the Aeroflot Open, with my brief notes:

1.d4 Nf6 2.c4 g6 3.f3 d5 4.cxd5 Nxd5 5.e4 Nb6 6.Nc3 Bg7 7.Be3 0–0 8.Qd2 Nc6 9.0–0–0 f5 10.h4 fxe4 11.h5 gxh5. A well-known theoretical position, which I consider to be better for Black. Here my opponent played a move which was new to me. 12.d5 Ne5 13.Bh6 Nec4. I also looked at Rf7, but I did not like the fact that after Rh5 the knight is attacked with tempo: 13...Rf7?! 14.Bxg7 Rxg7 15.Rxh5. 14.Qg5 Rf7. The only move. 15.Bxc4. This move seemed dubious to me, but objectively, it is not bad. 15...Nxc4. After thinking over his previous move for 40 minutes, my opponent now offered me a draw. However, I considered that I had a serious advantage, and saw no grounds for taking a draw. 16.Rd4? It seemed to me as though the move Qd6 gave me a serious initiative. It turns out that instead, Nb2 led to a decisive advantage, but I did not consider this move. Just think how much I would be to blame if I had analysed this position at home!? 16...Qd6?! 17.Bxg7 Rxg7. The only move! 18.Qxh5 Qf4+. Also forced, and mate was threatened, and the knight en prise. Now I would invite any competent player to give themselves three minutes on the clock, and try to find Black's next three fairly straightforward moves. I think the majority of people would manage this! 19.Kb1 Bf5 20.fxe4 Bg4 21.Nge2? Losing immediately. 21.Qh6 Qf2. 21...Qd2! 0–1. Black has a winning position. Here, my opponent stopped the clocks and, without shaking hands or signing the scoresheet, approached the arbiters' table. The rest you know yourselves...

I believe that every chessplayer, regardless of titles or ratings, should have respect for himself and his colleagues, and should not make accusations of computer use, without any foundation or evidence whatsoever. Especially when they have played the game quite weakly! Mamedyarov's claim, that I left the playing hall after every move, taking my coat with me, and went into the toilet, does not correspond with the facts. During the first twelve moves, which we played quite quickly, I did not once leave the hall. Whilst my opponent was thinking for 40 minutes over his 15th move, I twice went to the smoking area, which was located just two metres from the door into the hall, and where there were always quite a few other players, arbiters and also security guards. I also several times went and splashed cold water over myself, without ever speaking to anyone. Neither before, nor after, the protest did the arbiters show any unusual interest in me, as claimed in the press. I behaved exactly as I always do. Whilst my opponent is thinking, I find it easier to think about the position whilst walking round, without looking at the board. As far as I know, most other chessplayers do exactly the same.

Unfortunately, all these negative things could not but have an effect on my play in the rest of the tournament... I should like to thank all those who supported me on the pages of the Internet, or in personal conversations. I should also like to make the following proposals:

That the organisers of top tournaments install metal detectors and other such devices at the entrance to the playing hall, so as to exclude the possibility of players receiving outside help, and also to rule out unfounded and insulting accusations, which can seriously impact on a player's reputation.

That the international chess organisation adopt a rule, under which serious sanctions would apply both to those who use outside help, and also to those who make unfounded accusations of such, against other players.

IGM Igor Kurnosov

Shakhriyar Mamedyarov (2724) - Igor Kurnosov (2602)

1. d4 Nf6 2. c4 g6 3. f3 d5 4. cxd5 Nxd5 5. e4 Nb6 6. Nc3 Bg7 7. Be3 O-O 8. Qd2Nc6 9. O-O-O f5 10. h4 fxe4 11. h5 gxh5 12. d5 Ne5 13. Bh6 Nec4 14. Qg5 Rf7 15.Bxc4 Nxc4 16. Rd4 Qd6 17. Bxg7 Rxg7 18. Qxh5 Qf4+ 19. Kb1 Bf5 20. fxe4 Bg4 21.Nge2 Qd2 0-1*

Personally, I believe GM Shakhryiar Mamedyarov needs to step forward and apologize. With the lack of evidence I see no other alternative. Any thoughts on the issue?
