Adrian Mikhalchishin:
Prokesh trick
In Rook and pawn endings there are many
interesting and instructive manoevres. I want
to show few interesting examples, which
show some problems of top players in the
endgame.
There
are
strangely
many
mistakes, practically in evry example. But
we try to show this problems, which in
reality are quite simple and we hope that our
readers will not make similar mistakes in
their future games. It started in the next
game:

And white resigned here, as they knew the
development.
3.Rxb3??
Intermeditory check was unkown for player
of Grandmaster level - 60.Tb4.
3...c2 4.Rb4+ Kd5 5.Rb5+ Kd6 6.Rb6+
Kc7 0:1.
We could compare our first example with
the modern game.

And opponents agreed draw, as they was not
aware of the analysis of great Tarrasch.
1...b3 2.Rd8+ Kc5
2...Kc4? is not good, because of 3.Ke4.
3.Rc8+
Immediately loses 3.Ke4 b2 4.Tc8+ Kd6
5.Tb8 c2.
3...Kd4 4.Rd8+ Ke3 5.Rb8 b2 6.Ke5 Kf3!
6...c2 7.Tb3 was white's last chance to save
the game, which Black does not allow.
7.Kf5 Ke2! 8.Ke4 Kd1 9.Kd3 c2
And Black wins. This nice manoevre,
discovered by Tarrasch, has to be known not
only by GM's.The way of pushing own
pawns is in many games completely wrong,
despite the fact that it looks so simple.

5.b8Q Rb8 6.Kb8 g4 7.a7 g3 8.a8Q and now
White queened much faster than Black.

White managed to save this position.All of
this is known by the top players, but
sometimes it is well forgotten. Draw.

7.Rh8 Kb2 8.Ke4 a2.

4...Kb3 now does not help: 5.Kd6 Ka2 6.Kc5
b3 7.Kb4, with draw.
5.Ra4+
Gligoric is not Lutikov, or he simply studied
on the mistakes of the others.In the next
example, classic proudly showed the correct
way, how to promote own pawn. Draw.

6.Kd5 Rf5+ 7.Ke6 RXg5 8.f7 was simpler.

Ke6 11.f7 was winning, but a bit more
complicated. 7...Re1+ 8.Kd6 Rd1+ 9.Ke6

But in just few years it was impression, that
he has forgotten his own analysis. 1:0.

It was possible to transfer into classical
winning Rook end: 1.Ka6 Ra4 2.Rxh2 Rxb4
3.Rh6 Kf4 4.Rb6 Ra4 5.Kb5 Ra1 6.a6 Ke5
7.Kc6, or to sacrifice Rook immediately -
1.Rxh2 Kxh2 2.Ka6 Kg3 3.b5 Kf4 4.b6 Ke5
5.b7 Rb1 6.Ka7 Kd6 7.b8Q+ Rxb8 8.Kxb8
Kc6 9.a7 winning.
1...Rc1+ 2.Kb6
Now it was too late to try to return back, as
sometimes is still possible in some ends.
Chess is timing - used to say great Robert
Fischer: 2.Kb5 h1Q 3.Rxh1 Rxh1 4.a6 Kf4
5.a7 Ra1 6.Kb6 Ke5 7.Kb7 Kd5.

with checks it would be possible to drive
opponents King to the f file, after what f
pawn can be stopped with check.

1.Rg8??
Too beatiful to be true! It was possible to
stop a pawn with different measures. For
example: 1.Rg3 a2 2.Rd3+! Ke6 3.e8Q Rxe8
4.Ra3 Rb8 5.c4 (5.Rxa2 Rxb5 6.Ra6 Kf7
7.Rc6 was still easily winning) 5...c6!
6.Rxa2 cxb5 Rxb5 7.Rf2 Kf7 and it is not
easy to progress.
1...Rxg8 2.f7 a2??
2...Rxg2!! - Prokesh trick at that time was
unknown for both worldclass players!

immediately: 1...f3! 2.Rxg5 (2.Rc5 Rxc5
3.Kxc5 Kd7 4.Kb6 Kc8 –+) 2...Rxc7 3.Kxc7
f2 4.R6+ Kf7 –+, winning as in the first

5.Kb7 Kf6 6.Rg8 Ke5 7.c8Q Rxc8 8.Kxc8

Other maoevre does not help: 9...Kf3 10.Ke6

Much stroner than immediate capture on h4.
2...Kf4 3.Rxh4 Rd1+ 4.Kc3 Kf3 5.Rh6 g3

Another option was to bring Knight back
into defence. It looks to be stronger: 7.Rg6+
Kf4 8.Na6 e5 9.Nb4 e4 wwith advantage for
Black.
7...g2 8.Rg6+
Not sufficient to achieve draw was 8.Rxb6
Kh5 9.Tb5+ Kh6 10.Rb6+ Kg7 11.Tb7+
Kh8 –+. 8...Kh3?
Of course not 8...Kf3 9.Rxg2 Kxg2 –+.
9.Rh6+ Kg3 10.Rg6+?
And opponents agreed draw, but fight Rook
aainst Knight (10...Kf3 11.Rxg2 Kxg2) was
clearly winning for the stronger piece.

Sometimes happened, that Prokesh idea is
performed by other piece.
1...Ke6??
1...Kg6 was avoiding all opponents Knight
tricks. Now white performed trick with
Knight! 2.Ne4! Nc8+
Did not worked 2...g2 3.Ng5+ Kf5 4.Nxf3
and both pawns are stopped!
3.Kb7 Nxa7 4.c7 Ke5 5.Nxg3 Kf4 6.Nf1
Ke4 7.Rc5 f2 8.Nd2+ Ke3 9.Rf5 Kxd2
10.Rxf2+ Ke3 11.Rf8 Nb5 12.Re8+ Kf4
Draw.
Conclusion: knowledge of the key Prokesh
trick is necessary for players of every level.
But quantity of mistakes support our
opinion, that many players have to study it
much more seriousely.
