Chess Endgames 12 – Rook vs Knight – fritztrainer DVD – ChessBase
Unless you are new to chess or just returning to chess after
an absence of several years you are most likely aware of German GM Karsten
Muller’s excellent DVD series on the endgame.
With this release, GM Muller continues his quest to impart
high level endgame knowledge to the viewer.
This time in an ending that, while somewhat rare, is difficult to
convert without the knowledge of how to do so.
This DVD is broken down into eight chapters. They are:
1.
Rook versus Knight
2.
Two Rooks verses Rook and Knight
3.
Rook and Bishop versus Bishop and Knight With
Opposite Colored Bishops
4.
Rook and Bishop versus Bishop and Knight With
Same Colored Bishops
5.
Rook and Bishop versus the Knight Pair
6.
Rook and Knight versus the Knight Pair
7.
Rook versus Bishop and Knight
8.
Rook versus Two Knights
ChessBase was kind enough to send me this DVD to review, and
so after watching the DVD here are my thoughts…
First of all, let’s acknowledge just exactly what it is that
we are dealing with here….is Knight versus Rook an ending that you can expect
to play frequently? The answer to that
is no, it is quite rare. How rare is it
you ask? So rare that it happens roughly
one in every 100 endgames (0.97% to be exact according to Fundamental Chess
Endings which was written by GM Muller back in 2001 along with Frank
Lamprecht.)
So what is the value in studying something that you will
only see a handful of times in your career?
Well, one answer is that perhaps someday you’ll face it in the last
round of a tournament with $5,000 on the line.
But that’s not likely. What is
likely is that you will be able to take the concepts that you learn from the
study of this endgame and apply them to late middlegame situations as well.
For example, GM Muller introduces the concept of the “knight
check shadow” early on in the DVD. Here
are the main two examples:


The idea of the knight check shadow is to force the knight
to spend more tempi to get where it needs to be, if indeed it can get there at
all.
Another benefit to this DVD is that when you take all of the
various configurations covered in the chapters and add them up you are looking
at approximately 20% of the endgames you will play.Here is an ending from Chapter One that illustrates the knight check shadow technique:
Ju – Kosintseva 2011

.

Black begins by exchanging off a pair
of rooks to alleviate her cramped position, but ultimately White is then able
to dominate the Black knight by using the knight check shadow technique.

After watching the analysis clip of the position above I gained an
appreciation for these types of endgames where the appearance can be
deceiving. I looked at the position
before watching the clip and thought it to be a dead draw. After hearing GM Muller explain the concepts
(for example the misplaced pawn on g5) I will be more mindful of these items in
my own games.
Chapter Two is Two Rooks vs Rook and Knight. This chapter starts out with an example taken
from a game between Garry Kasparov and Evgeny Bareev from Novgorod 1997.
Here is the starting position of the video clip:

GM Muller starts off by pointing out that when there are no pawns on the
board then positions tend to be drawn the majority of the time, but that White
has chances to play for the win.
In the game Kasparov played 72.Rg6!? and then after 72…Re3?
73.Re6 Bareev resigned as he can’t prevent the loss of the knight.
However, Bareev could have played:
72…Kh3! as after 73.Rb3+ Kh2 the position is a draw.
In fact, I let Houdini run for 34 minutes in this position and clipped
the analysis below. Feel free to play
through it to see the ideas.
Analysis by Houdini 1.5a w32:
1. = (0.26): 73.Rb3+ Kh2 74.Rg4

Kg2 95.Rc2+ Ne2 96.Rf8 Kg3
When pawns are on the board it can be a completely different matter. Here is a famous example of this type of
endgame from St. Petersburg 1914 between world champion Emmanuel Lasker and
future world champion Alexander Alekhine.
GM Muller first discusses this position:


If either of the Black rooks were removed along with the White rook then this is an easily winning position for Black, a fact which is confirmed by six piece tablebases. Therefore Black’s plan here will involve trading off a set of rooks.
GM Muller then fast forwards to this position:

In the interests of space I won’t cover examples from every chapter, but
suffice it to say that each of the remaining chapters also breaks down ideas
and concepts into variational truths such as the examples given above.
My opinion of this DVD is that this is something that pretty much any
player serious about improving should own, if for no other reason that a lot of
this material is sparsely covered elsewhere.
Does this mean that you are likely to start getting these endgames in
your own games? Not necessarily, but
many of these concepts will translate into late middlegame concepts. Also, knowing the material in this DVD gives
you one more weapon in your arsenal as you will have know when to trade into
these endgames with confidence.
I give this DVD four out of five stars.
I really experienced studying your publish. very nice
