-> gameknot.com ——— A Showdown in Bulgaria for the World Championship — A World Chess Championship match that begins on Friday in Sofia, Bulgaria, between Viswanathan Anand of India, the titleholder, and Veselin Topalov of Bulgaria, a former chess champion, should be a treat for fans. Anand and Topalov are dynamic, and each can land a knockout blow if an opponent slips up. Both are excellent at preparing openings, so the match could come down to which of them has the fresher ideas. Since September 2008, Anand, 40, has slipped from No. 1 in the world to No. 4. That slide can be blamed on his inactivity — including preparations for this match — rather than a decline in his skills. He has been among the world’s top five chess players for ...

-> www.chesskit.com ——— Previewing the world chess championship match — The world chess championship match between champion Viswanathan Anand of India and Veselin Topalov of Bulgaria begins Friday in Sofia, Bulgaria. The schedule calls for a rest day after every two days of play except that there will be an additional rest day May 9, between the 11th and 12th games. If the score reaches 6-6, the players will break the tie with a series of faster games May 12. Topalov, ranked second in the world at 2805, deserves to be considered a slight favorite over Anand, fourth at 2787. However, one can imagine almost any outcome. Anand has more experience in chess matches and he plays more soundly, with better judgment, but Topalov is more ...

5/24/2006 06:04:43 Play online chess | how to mate...
Message: Ok, some explanations (because I feel that the given site doesn'T really explain the idea)...
First, the mating process consists of three steps:
1) centralize your king and pieces
2) drive his king to the boarder
3) mate him in the corner that your bishop controls.
Now, take out a board and set up pieces (I just go through one of my mates to show you the ideas, then you should simply play this a dozen times against a computer, because it's essentially always the same).
First idea is to realize that your knight and bishop can form a kind of barrier: imagine Bc2 and Ne2. Now, you control the squares a4, b3, c3, d3 and d4. Were his king on c4, he couldn't come closer to your pieces. Imagine your king now coming from the side (Kd4, maybe), and his king would have to go back...
One further general remark: The key to this mate is not constant threats but confinement.
***Don't think primarily about pushing his king, but more about cutting off his escape route!***
Now, here's my game...
Start: wt: Kc2, Nb7, Bg7; bl: Kg4
1. Kd3 (remember the first step - centralize your king and your forces) Kf3 (of course he knows that doom awaits at the rim - therefore he tries to centralize as well)
2. Nd6 Kf2 (after ... Kf4 Kd4, he has to go to the rim anyway. But he's struggeling to keep away from it as long as possible)
3. Ke4 Kg2
4. Bd4 Kg3 (trying to stay off the back rank. If he had moved there, Kf3 would have kept him there...)
5. Be3 Kg2
6. Nf5 Kh2 (finally!!!)
7. Kf3
-------------
Ok, this was only the prelude. This is the first position you have to memorize. Of course, it can occur on all four corners. The basic position is always characterized by your king on f3, c3, c6, or f6 (depending on what bishop you have). His king is driven into the corner. And there he will stay unless you drive him towards the corner where you can mate him. The next moves are basically forced and should be simply learned by heart. The first is to bring the knight in...
-------------
7. ... Kh3
8. Ng3
This is the position you're aiming at. Doesn't matter if it takes a couple of knight moves to get to g3 (or, if he goes the other way - h1-g1 etc., Nf2 - it doesnt matter). As you can see, his king can't escape: g2,g3,g4 are covered by the king, h5 and h1 by the knight and g5 and g1 by the bishop. Even if the bishop were not on e3, you would always have the time to keep him in by moving the bishop towards the right diagonal to cut off his escape route.
8. ... Kh2 (of course, staying away from the corner where he can be mated!)
9. Bf2 (exclam! This move is important. Remember my remark about confinement above? This is what you're doing right now: This one move is simply "loosing" a tempo such that he has to move again...
9. ... Kh3 (only move
10. Bg1 (taking away that square - now the king has no choice but to move up...) Kh4
-------
Ok. So far, so good. Now comes a series of moves that at first sight strike you as completely counter intuitive. You simply HAVE to learn those by heart. As mating with k+b takes up to 28 moves (especially if you let his king slip now), you'll likely not make it within 50 moves and the game would be drawn. So you HAVE to know those moves.
--------
11. Ne4 Kh5 (don't worry why he's going up voluntarily - we'll come back to that)
12. Kf4 Kg6
13. Ng5
Those are the magic moves you simply have to make! Once you've reached this position, it's not that hard anymore, because the above confinement-idea comes in again.
13. ... Kg7 (now, it _looks_ like he's getting out, doesn't it?)
14. Bc5!! Taking away the escape route! No checks, just keep him under control!
14. ... Kf6
15. Bf8 (See how bishop and knight take away every square he would love to move to?) Kg6
16. Be7
---------
That was the next maneuver you have to know - though the moves are not completely forced (he could go to f6 right away on move 13, for example), But still, that bishop maneuver, cutting off his escape is the same. It's the only move, and it's somewhat hard to find if you are looking for a direct threat but if you are thinking "how do I cut off all his exits?" it's not that hard anymore. The next bishop moves were (similar to that Bf2 move in the beginning) kind of "waiting moves". The idea is to drive the king off the dark squares to be able to control those. Now, you can see that Bishop and knight form a barrier from f8 to f6! That's important.
-------
16. ... Kh5 (back to trying to stay away from the mating corner)
17. Nf3 The last difficult maneuver. The idea is twofold: First, it frees the diagonal, forcing the king up, and secondly, it aims to control f7 again by going to e5.
17. ... Kg6 (hoping to escape via f7!)
18. Ne5+ (denying f7!) Kh5
19. Kg3 (now you're simply herding the king into the corner.) Kh6
20. Kg4 Kg7 (but no exit point for him!)
21. Kg5 Kh7 (almost there. As white mates with the king on g6 or f7, black tries to deny that square as long as possible.
---------
Here comes the last little trick to know. Now, you have to take away the last few squares. Again, it's confinement rather than direct treats.
22. Bf8 Kg8 (now, he has only three squares left)
23. Bh6 Kh8
24. Kg6 (ok, the king is set - that's his mating square. Had he moved Kg7 on the previous move, you'd have simply "lost" a move by playing Kh6)
24. ... Kg8
25. Ng4 Kh8
It's important now to not stalemate him by playing Nf6!!
So, now:
26. Bg7+ Kg8
27. Nf6# :))
---------------------------------------
Back to move 11 where I said that you shouldn't worry that the king goes towards the corner of mate rather than continuing to try to stay away from it. The reason is simple...
11. Ne4 Kh3
12. Ng5+ Kh4
13. Kf4 Kh5
14. Kf5 Kh4
15. Bh2 Kh5
All those moves were forced. And if you look at the position of the pieces relative to each other, it's exactly the same position you had after 10. Bg1! The only exception is, that now, the king is a) farther up the board b) even without that little chance of outrunning you. Therefore, it's not the best defence.
Hope, that helps some... ——— Final two rounds produce an exciting climax to the German chess league — Russia's national chess league may be the strongest in the world but Germany's Bundesliga runs it close and its media profile is far higher. The final two rounds last weekend began with Baden-Baden and Solingen on 24 points from 13 matches, Werder Bremen 23 and Mulheim 20. Baden-Baden is the cash-rich team and even boasts the world chess champion, Vishy Anand, and world No1, Magnus Carlsen in its squad, though the Indian has played only two games and the Norwegian none. But the active regulars are so strong that Michael Adams, the England No1, plays only on a mid-board in the eight-man team. Werder Bremen, which has links with the football club, fields ...

Message: thank you , ive learned it now and feel its a great accomplishment as a chess player! ——— Robot chess opponent — Hopefully Dennis who is playing with a a robotic arm as his chess opponent has not input the necessary code to have the arm reach over and choke the life out of him should he win the chess match. The Lynxmotion AL5A robotic arm is, after all, full well capable of plucking each chess piece and moving it to the next space. This is made possible thanks to a Python script Dennis himself created to process the moves and decide on the next move. A webcam is used to capture the location of the desired pieces on the chess board in order to help it in its task. ...
