Chess Endgames 1 - Basic knowledge for beginners

Endgame theory constitutes the foundation of chess. You realize this in striking clarity once you obtain a won endgame but in the end have to be content with a draw in the end because of a lack of necessary know-how. Such accidents can only be prevented by building up a solid endgame technique. This is Karsten Müller‘s fi rst DVD and the grandmaster from Hamburg and endgame expert, here lays the foundation for acquiring such a technique. The fi rst part of his training series can be started without any endgame knowledge, only a knowledge of the rules of chess is assumed.

As could be expected, you're completely right.
Well, even so, had to do it. Following Botvinnik: analyse and publish it. Makes it less non-commital.

Frits Fritschy: After 66 Na2 Be8 67 Nb4!? Bd7 68 Nd3 Kd5 69 Kc7 Black plays 69...Be6 and wins, e.g. 70.Kd8 Kd4!-+.
Frits Fritschy Frits Fritschy 2/19/2021 12:18
... and I still wonder whether it is really won. I looked tonight at 66 Na2 Be8 67 Nb4!? Bd7 68 Nd3 Kd5 69 Kc7. So far, so good. Where is the bishop going? 69... Be8 70 Kd8 Bg6 71 Ke7 Ke4 72 Kf6 looks like a clear draw. 69... Bb5 70 Ne5 Ke4 71 Kd6 Ba6 72 Ke6 Bc8+ 73 Kf6 Ke3 74 Kg5 Kf2 75 Kh4 and Perseverance, after a long journey, has landed safely. The most difficult was 69... Ba4 70 Ne1 Ke4 71 Kd6! (Don't rush with 71 Ng2 Kf3 72 Nh4+ Kxg3 73 Nxf5+ Kxf4 and it's a tablebase win here.) 71... Bb3 (71... Ke3 72 Ke6 Bc2 73 Nh4 Kf2 74 Nxf5 and white is just in time) 72 Ke7 Ba2 73 Ng2 (73 Kf6? Bb1 74 Kg5 Ke3 and because of the threat Kf2, white is too late) 73... Kf3 (73... Bb1 74 Nh4! neatly keeping the king from f3) 74 Nh4+ Kxg3 75 Nxf5+ and this is a tablebase draw! (75... Kxf4 76 Kf6!) Maybe missing something, but I call it a day now.

Frits Fritschy: Really very deep! The position is indeed very rich, deep and fascinating...
Frits Fritschy Frits Fritschy 2/18/2021 10:08
Not deep enough: in the line of my second comment, 70 Nb3? loses to 70... Bb5 71 Ke1 Ke3! (the move I forgot about) 72 Nd2 Bd3. However, 70 Nc6 draws anyway, as after 70... Bb5 71 Ne5 black has no useful move with the bishop on the a6-f1 diagonal. 71... Kf3 72 Nd4+ reverts to the original line.
Karsten Müller Karsten Müller 2/17/2021 09:11
Frits Fritschy: Yes 63...Ba2? 64.Kb4! indeed draws. Very deep!
Frits Fritschy Frits Fritschy 2/17/2021 07:45
... but not 63... Ba2 64 Nc1? Bg8! 65 Kb4 Kd5 66 Kc3 Ke4 67 Kd2 Kf3 68 Ne2 Kf2 69 Nd4 Bh7 70 Ne2 Bg6 71 Kd3 Be8 72 Ke2 Bd7 73 Kd1 Bc6 74 Kd2 Be4 75 Nc3 Bf3!
Fascinating endgame! I had some help from the online engine, but that also struggles - it doesn't notice the tablebase draw in my second comment, for instance, giving over -2.00.
Frits Fritschy Frits Fritschy 2/17/2021 12:25
... however, after 63... Ba2 64 Kb4 seems to draw: 64... Kd5 65 Nc1 Bc4 (sacrificing the bishop with Ke4 doesn't win either) 66 Kc3 Bb5 67 Nb3 Ke4 68 Kd2 Bc4 69 Na5! (69... Bd5 70 Ke2 doesn't bring anything; 70... Kd4 71 Kd2 Kc5 72 Kc3) 69... Ba6 (69... Bg8 70 Nc6! but not 70 Ke2? Bd5! Zugzwang) 70 Nb3 Kf3 71 Nd4+ Kxg3 72 Nxf5+ Kxf4 73 Ng7! and to my surprise, this is a tablebase draw (also with the bishop on a2 or g8).
Frits Fritschy Frits Fritschy 2/16/2021 11:13
I wonder, isn't 63... Ba2 winning as well? My main variation is 64 Kb6 Bb3 65 Nc5! (65 Nb4 Ba4 is your main line) 65... Bc2 66 Na6 Bd1 67 Nc7! (67 Nb4 Ba4) 67... Ba4 68 Kb7 Bd7! (Not too quick with 68... Kc5? 69 Ne6+ Kd5 70 Ng7) 69 Kb6 Bc6 70 Na6 Be8 71 Kb7 (and again 71 Nb4 Ba4) 71... Bd7 72 Nb8 Ba4 73 Kc8 Kd5 74 Nd7 Ke4! 75 Nc5+ Kf3 and wins.

It looks so simple and straight forward, and yet what a complex endgame. Thanks, Karsten, appreciated!
Karsten Müller Karsten Müller 2/16/2021 03:06
Frits Fritschy: Yes and the win for Black is not so obivious, even when you knows that there is one...
Frits Fritschy Frits Fritschy 2/16/2021 02:39
McShane had an easy draw with 61 Nd3 Kd6 62 Ka5, but okay, it was online rapid.
Karsten Müller Karsten Müller 2/16/2021 12:41
PhishMaster: In a way you are right. The main line indeed ends with -+ and Black is winning from the beginning of the exercise. But the game was won by GM Luke McShane with White. I should have changed it to -+ at the end of the main line..

When I read "influencer", I really expect a pretty girl in a bikini. :) No, seriously, the result appears to be wrong. It says 1-0, when it should be 0-1.
