|Jan-26-19|| ||rogge: Probably a joke|
|Jan-26-19|| ||ChessHigherCat: Carlsen can mate with a bishop and a knight but they wouldn't produce offspring.|
|Jan-26-19|| ||thegoodanarchist: < OhioChessFan: I wonder if Carlsen can mate with Bishop and Knight...>|
I was hoping to see that. Clearly, Duda was not interested
|Jan-26-19|| ||Olsonist: It depends on the denomination.|
|Jan-26-19|| ||Penguincw: < OhioChessFan: I wonder if Carlsen can mate with Bishop and Knight... >|
The Endgame Explorer doesn't have any Carlsen BN vs. K endings, so we'll never know.
Carlsson was on the wrong end of one once. P Carlsson vs M Panchanathan, 2016
|Jan-26-19|| ||Dave12: <Penguincw: The Endgame Explorer doesn't have any Carlsen BN vs. K endings, so we'll never know.>
The closest thing he had to that ending, I think, is Carlsen vs Aronian, 2012 where black resigned before testing his B+N mating ability.|
|Jan-26-19|| ||OhioChessFan: < I wonder if Carlsen can mate with Bishop and Knight...>|
It's happened to a World Champion before. Of course, this was my reference:
A Ushenina vs O Girya, 2013
|Jan-26-19|| ||csmath: Mating with bishop and knight is not so hard so any master candidate should be able to do it. It takes about 30 moves max. |
The idea is simple - block the opponent's king with a main diagonal and then forcing it to a smaller and a smaller diagonal. The final corner has to be of the color of the bishop. It is really not hard.
I know I practiced that as a young player and I had one game where I deliberately promoted bishop instead of a queen just to practice against human opponent. It was not a problem at all though I think I spent a little more than 30 moves.
The harder thing is to win with a queen versus a rook.
But I am sure Carlsen would have no problem to do either and I am sure that Duda felt that was really not something he would want to waste time on finding out.
|Jan-26-19|| ||Monocle: Magnus could probably do it with 30 seconds on the clock. Once you know the technique, it's trivial.|
|Jan-26-19|| ||csmath: I would definitely bet that Magnus would do that in no more than 2 minutes. 30 seconds, I don't know about that ...|
|Jan-26-19|| ||csmath: One of the things that Magnus did for chess world is to put the emphasis back on the endgame.
I think he has shown quite convincingly that the world chess champion needs to have immaculate endgame skills set. This is good for the game and for all the young players everywhere. It teaches them the required discipline in the learning process.|
|Jan-26-19|| ||Count Wedgemore: <OCF: It's happened to a World Champion before.>|
A World Champion whose peak rating was 2502.
|Jan-26-19|| ||Count Wedgemore: <ChessHigherCat: Carlsen can mate with a bishop and a knight but they wouldn't produce offspring.>|
Don't know about knights, but many protestant denominations have female bishops, so..ehh..technically they could have produced offspring in some cases..
This is really not a discussion to be pursued further in my NOT SO HUMBLE opinion.
|Jan-26-19|| ||frogbert: This one of Carlsen's best tournament performances in a long time! And I'm thinking as much in terms if his play as his result so far. He was even somewhat unlucky to face Kramnik and Fedoseev in games where they played really well - while Giri has been as lucky as anyone can hope for, regarding his two last games.|
Anish might still win the tournament. It will take only one bad game by the world champion.
|Jan-26-19|| ||rogge: Jan Gustafsson said that 10. Rd1 was a prep for the Caruana-match :)|
|Jan-26-19|| ||DansChessLounge: The ending position was going to be Bishop & Knight vs King. Do you know how to win that endgame? Check out the video to see how---> https://youtu.be/WiBC-dPbIxs|
|Jan-26-19|| ||Count Wedgemore: <Frogbert: This one of Carlsen's best tournament performances in a long time! And I'm thinking as much in terms if his play as his result so far.>|
Agreed, <frogbert>. Of course, there have been others; he had, for instance, a good Tata Steel tournament last year as well. The Open tourney on the Isle of Man some months before that was also good, at least results-wise, that is.
But in terms of quality of play, I'd venture to say that this may be his best tournament since the 2015 Gashimov Memorial where he played some phenomenal chess. He had a great LCC tournament also that year. This was on that level.
|Jan-27-19|| ||Ulhumbrus: One point of 50 Kd2 inducing the advance 50...c3+ is that the withdrawal ...Ke5 allows the fork Nd3+ as the c pawn covers no longer the square c4.|
|Jan-27-19|| ||Ulhumbrus: The move 54 Rb1! which offers the h pawn makes ready a combinative resource.|
On 54...Rxh5 55 Bxe4! Black's f pawn is overworked. If it has to obstruct the fifth rank against the skewer Rb5+ it cannot then defend the e pawn and take White's bishop.
This game suggests that Carlsen's endgame skill includes such combinative resources as he employs in this game.
Suppose that we assume that such combinative resources must count as a part of the technique of such endgames.
This suggests then that Carlsen's endgame skill is more complete to this extent.
This suggests in turn that to the extent that any player's endgame technique lacks such combinative resources it is incomplete.
|Jan-28-19|| ||johnkr: A bewildering game! Magnus in his element and I noticed that very few of the annointed commentators could really shed light... is it a clear win for White or does BLack have drawing chances? However using the engines, I'm finding one promising idea here: instead of Black's 45th Rb6, he can try 45... Rd5 46. Nf4 Rd6 47. Be2 the White advantage recedes. To explain in English it does seem like the White king is boxed in by the 2 Black rooks on b and d files now whether a Magnus could overcome this, who knows, maybe the truth will emerge in later and more careful analyses.|
|Jan-28-19|| ||johnkr: However one more comment on this game, it took some cooperation by Duda - he was almost busted early by ...h6, a careless move. But granting that, it was still a phenomenal win.|
|Jan-30-19|| ||johnkr: Peter Svidler in his game analysis fingers Magnus' 43 Kc3 as inaccurate if black had found 43 ... Rd5! 44 Bc2 Rbd8 and now the Rook can enter d2, e.g. 45 a5 Rd2 46 Nf4 46 Rf2! with play. The engines seem to agree, White has now only a small plus. Granted it's not easy to find.|

This suggests or helps to suggest at least four things as follows.
1. It is a brilliant resource.
2. As someone else has said already, Svidler is a great player.
3. If, as Nimzovich has said in his books <My system> , the purpose of occupying an open file is to get a rook to the seventh rank, this resource pointed out by Svidler suggests that the purpose of occupying the seventh rank can be to switch to another file so as to become able to invade another rank.
4. This resource is instructive and serves to increase the knowledge and skill or resourcefulness of players who have learnt of Svidler's comment.
