Antoaneta Stefanova:
Missing the point? Don't!

How many times we hear from players "I
had a completely winning position and can
not believe I did not win the game"? Yes, it
happens to everybody. Of course, the
stronger the player, less often it occurs. But
still, even the top Grandmasters lose half or
even full points from winning positions.
Why does it happen? The answer to this
question is by no means simple, as the
reasons can be very different. Let's start by
defining what is a winning position, as many
people (including myself) use this words,
when in fact they have just an advantage, a
clear advantage, or a "practically winning
position", which is not the same thing. So,
what is the definition of a winning position?
It is a position, where if both sides play the
best moves, the weaker side will lose the
game. It sounds simple-the difficult part of
the game is done, one has a decisive
advantage, the rest should be easy... And yet,
as Lasker said "The most difficult thing in
chess it is to win a winning position". There
are a few major factors to spoil a winning
position.
Relaxation - the winning side basically
waits for the opponent to resign. Thinking
that the game is over, he loses concentration
and motivation to find the right plan or the
best moves to finish the game. Often the
moves played in such mental state are not
the best, just marking time, and as a result
the decisive advantage starts to disappear. A
"relaxed" player also tends to lose his
vigilance and allows the opponent to create
some counterplay, which, of course is not
advisable.
Miscalculation - this can be linked with the
relaxation, but there are other subject
connected as well. Unlike the computers, the
human players can not calculate every move
in a position. To narrow the choice, one

needs a good positional knowledge - to
evaluate the position correctly, identify the
opponents weaknesses and potential chances
for counterplay. Once this is done, the right
candidate moves come easier. Another thing
is a poor calculation ability-but this can be
easily improved by regular training with the
right positions to analyse and calculate.
Time-trouble - it is a major factor in
tournament play, which can lead to a
disaster, drawing or even losing any winning
position. It can be a problem for players of
all levels, and a very difficult one to get rid
off. The most common factors leading to
time-trouble are:
- Poor knowledge of openings, typical
middlegame positions or endgames.
- Lack of self-confidence.
- The desire to find the absolute best move in
every position.
Having said all this, one should keep in mind
also, that the different types of winning
positions require different approach. In this
Survey I have gathered instructive examples
from recent tournament games from some of
the best players of the world.

A. Kosteniuk : V. Gunina
Russia 2018

Watching this game from the recent Russian
Superfinal provoked this article. We see two
of the best female chess players in the world
– ex-World Champion Alexandra Kosteniuk
against the reigning European Champion
Valentina Gunina. The game is very
entertaining, but filled with unusual number
of mistakes and missed winning
opportunities from both sides. Let's try to
understand what led to this errors.
1.c4 e6 2.Nc3 d5 3.d4 a6 4.Nf3 Nf6 5.Qc2
A novelty on move 5? Well, I managed to
find only one game in the database with this
move played. I wonder what Kosteniuk had
prepared against the most logical 5...dc4.
5...c5
5...dc4.

Also a good move, giving White clear

13.Rd8 Rd8 14.ab4 Bb1 15.Bf6+–. It is not
easy to calculate all the lines, but seems
logical to try to punish Black's dubious plan

immediately. Could it be that Kosteniuk
simply did not believe that she could achieve
a winning position after only 10 moves?

A critical moment in the game. White is a
piece up, but still has to find the best way to
finish her development and cover the King.
Black, however is playing correctly-there is
nothing more to lose, so, Gunina is trying to
pose maximum problems, hoping for a
mistake.
17.Nd5?
A serious error, after which Black can get a
draw. At this point of the game both players
were already short of time - White had 23
minutes left and Black only 10. This easily
explains the number of mistakes by both till
the time control. The reason to spend so
much time for the first 16 moves looks also
quite obvious - not enough theoretical
knowledge and the complicated nature of the
position.
17.Qh4!+–. The best move, which wins

immediately. Threatening to exchange the
queens, thus gaining time for the
development. Very soon all Black's
attacking chances disappear: 17...Rae8

After this natural move it is suddenly White
who is lost! 27.Ke3? Re8 28.Qe4 Qb3
29.Rd3 Re4 30.Ke4 Bf5. 27.Kg3 would keep
the advantage.
27...Rc8?
Black loses the opportunity to take the
advantage, allowing White to sacrifice her
Queen, going to a better ending.

28.Qc8 Bc8 29.Ke3±
At first sight it may appear as Black should
have enough compensation for the piece -
potential passed pawns on the queenside,
and the White King in the center. But, there
is no perpetual check, and the pawns are far
from being dangerous. So, it is White who
has a clear advantage, due to the potential
mating threats.
29...Kg7?!
29...Bf5 This might be a more stubborn
defence, but does not solve Black's problems
in the long run. 30.Rd8 Kg7 31.Nd4 Bg6

30...Be6 31.Nd4 Ba2 32.Rf1
White sacrifices a pawn in order to activate
her pieces as soon as possible. It is the way
to win such endgames-with two rooks and a
piece against a queen. Of course, there was
nothing wrong with first defending the pawn
or exchanging it and then switching to the
attack, as Black does not have any
immediate threats. 32.b5!?±.

Strangely enough, it is Black who deviates

White is not forced to repeat for a 3rd time.

temporarily restrained, and Black can start
with the checks. 40.Ra1+– Qc5? 41.Ke4

40...Qe5 41.Kd2 Qb2 42.Ke3 Qe5 43.Kd2
Be6?!
43...Qb2! For a second time in this game
Black could play exactly the same move
with a repetition and a draw. To be fair, this

time the decision to deviate from the
repetition looks a bit more justified - White
still has a small advantage, but her pieces are
not well coordinated and Black could hope
for some activity with the two connected
pass pawns.

White has a desicive positional advantage.
More active and coordinated pieces, control
over the e-file, combined with threaths to the

enough to achieve the victory. Still,the right
plan should be found.
24.Te5
It is hard to critisize this move. I am sure
that many strong Grandmasters would play it
without a second thought. Although it is not
the best move and plan, White's advantage is
huge and we'll see how many average or
even dubious moves it will take to spoil it.

It is the second game of Wesley So in this
article and from the same tournament - Wijk
an Zee 2018. It is amazing, that from two
completely lost positions, he managed to
score 1,5 out of 2, playing against two of the
best players in the World. Lucky? I would
not say that. Of course, he needed big help
from his opponents not to lose those games,
but the truth is that he kept fighting in
desperate positions, trying to create
counterplay and provoke his opponents to
err. When on the losing side, this is exactly
what a player should do!
24.La3?!
24.ba6! The simplest move is the best!
Getting more material and creating a very
dangerous pass pawn would be enough for
the victory. Black does not have enough

29.Dc8! looks very simple, but White can go
for this line only if he finds move 31.Rg4,
otherwise, he can get even inferior position!

White has many ways to win, but Nd8 is
important motiv in most of the lines.

28.Td5 Ld5 29.Sd5 Dd5 30.Sd8+–.
Even 28.Ld8 is also winning: 28...Ld8
29.Sd8 Td8 30.Sd5 Sc1 31.De5.
28...Ld5 29.Sf4?!
White fails to finish the game right away
with Nd8 or Rd5. After the move played in
the game he is still winning, but as it often
happens one innacuracy leads to another, till
the advantage slips away. 29.Sd8! De7

Once again,offered a wide choice of winning
moves,Ding fails to calculate correctly and
chooses a dubious continuation.
