Georg Mohr:
Rook against pawn
(Basic level)
We like to call these endings »rapid (fast)«
endings and in many cases we can
calculate everything, till the end, from
move to move. There are not so many
theoretical positions, but we shall study
typical, important techniques, which we
need to know for correct playing.
However, the most important are deep and
precise calculations.
PAWN STRONGER THAN
ROOK
All chess players shall know the famous
example, when single pawn is stronger
than a rook.
G. Barbier, F. Saavedra, 1895

In this example we will met a technique
with a name »moving downstairs«. It is all
about how to avoid checks.
1.c7 Rd6 2.Kb5!
2.Kc5? Rd1 3.c8Q? Rc1.
2...Rd5 3.Kb4 Rd4 4.Kb3
Or 4.Kc3 Rd1 5.Kc2.
4...Rd3 5.Kc2
King can step on »c« file only on second
rank to prevent check from behind. This
study is famous because of its beautiful
end:
5...Rd4! 6.c8R!!
If 6.c8Q?, then 6...Rc4! 7.Qc4 and
stalemate!
6...Ra4 7.Kb3+-.
CUTTING THE KING OFF
This is a very important technique by
which a player with a rook prevents an
opponent's cooperation between the king
and the pawn. We can effectively cut the
king on the fifth rank:

1.Rg5! +-.
Why this? Once the black pawn will
advance to the third rank (to a3), the rook
will simply attack it (Rg3) and the black
king will be too far to get help. So:
1...a4 2.Kg7 a3 3.Rg3! a2 4.Ra3
and the pawn is lost.
White can afford even a luxury and let the
black pawn to a2: 3.Kf6 a2 4.Rg1, with
further Ra1 and Ra2, but I advise you to
attack the pawn immediately.
With black on move, after 1 ... Kb5 (c5)
the position is a draw. Calculate the
variations yourself!

If we move the position one file to the
right, then the speed will be decisive again.
The king cannot be definitively cut off:

The king goes to a5 and a4. However, the
king manoeuvre loses time.
Calculate the consequences and the final
result after 2.Kg7!
PAWN PROMOTION TO A
KNIGHT

Black can also save himself by stalemate:
1...Kb1! 2.Kb3 Ka1! 3.Rb2 – stalemate!.
However, this is possible only in positions
with knight's pawns (b or g). With a central
or a bishop pawn his only technique to
ensure a draw is pawn to knight promotion.
2.Kc3 b1N! 3.Kd3 Na3 4.Ra2 Nb1!=.
It is very important to know that the move
4…Nb5? loses: in those endings the knight
must always be at the king's side!
If black has a rook pawn, this method does
not work.

There is no stalemate motif and also
promotion to the knight doesn't help:
1.Kc4 a2 2.Kb3 a1N 3.Kc3 +-.
Black will lose also with an additional
pawn on b file:

5.Kc3 Ne3 6.Rh4!
We will follow very instructive fight
between the rook and the knight.
Nevertheless, 6.Kd3 is enough, too:

knight is lost.

occurs many times.

Careful! Black will lose after 1...a2? 2.Rb8
Ka3 3.Kc2! a1S 4.Kc3 Ka2 5.Rb7 +-, what
we already know. The only correct way is:
1...Kb2! 2.Rb8
Or 2.Rh2 Kb3!=, but not 2...Kb1??
3.Kc3+-.
2...Kc1!
The crucial move of our defence!
3.Ra8 Kb2 4.Kd2 a2 5.Rb8 Ka1!=
5...Ka3? 6.Kc2+-.
AN INTERMEDIATE
CHECK
Next important technique is so-called
intermediate check. The idea is to gain a
tempo and to drive the opponents king to a
worse square.

1...Kf2 2.Rf8!
It is very important to understand that
2.Kd3? g3 3.Rf8 Ke1! leads to a draw!
2...Ke2 3.Rg8! Kf3
Due to the intermediate check, white drove
the opponent’s king from f2 to f3. Now,
after Kd3, white comes to opposition.
Black king cannot reach the saving square
e1 anymore!
4.Kd3 g3 5.Rf8 Kg2 6.Ke2+-.
SHOULDERING
We saw this technique in the previous
example. Everything is about such king
moves that don't allow the opposite king to
come closer to ours. We don't allow him to
take the shortest way, so he has to go
around.

After the logical:
1.Rh2
There is only one correct answer:
1...Ka3!
We already know the position after
1...Kb1? 2.Kb3 a1N 3.Kc3 – it is lost for
black, but with 1...Ka3 white does not
allow him to reach the winning square b3.

We already know the technique of cutting
off (after 1...a5? 2.Rh5). So, black has to
play with his king. But where – to b5 or
c5? There is a simple advice in such
positions: it is much more important to
play against the opponent’s king than to
support our pawn. However, don't forget
about the pawn, of course …
Wrong is 1...Kb5 2.Kf7 a5 3.Ke6 a4 4.Kd5
Kb4 5.Kd4 a3 6.Rb8 Ka4 7.Kc3 and white
wins.
Correct is 1...Kc5! After 2.Kf7 a5 3.Ke6
a4 white cannot play Kd5, so he cannot
achieve opposition. From e5 he is already
too late: 4.Ke5 a3 5.Rc8 Kb4 6.Kd4 a2
7.Ra8 Kb3 8.Kd3 Kb2 9.Rb8 Kc1!
OUTFLANKING
Practically everything about this motif is
said in the famous Reti study:

1.Rd2!!
Fantastic move, putting black in
zugzwang! »The only logical« 1.Rd1? is a
mistake: 1...d4, with shouldering to follow:
2.Kd7 (2.Kf7 Ke4 3.Ke6 d3=) 2...Kd5!
(Black prevents outflanking.) 3.Kc7 Kc5!
(3...Kc4? 4.Kd6 d3 5.Ke5+-) 4.Kb7 Kc4=.
A similar solution is 1.Rd3!!+-.
1...d4 2.Rd1!
A wonderful move: white loses a tempo,
forcing black to play. Now all his moves
are losing:
2...Kd5 3.Kd7!
Zugzwang – black has to show which side
he takes with the king.
3...Kc4
Or 3...Ke4 4.Kc6 d3 5.Kc5 Ke3 6.Kc4 d2
7.Kc3+-.
4.Ke6 d3 5.Ke5 Kc3 6.Ke4 d2 7.Ke3+-.
