Jovan Petronic:

The King Checkmates

The game of chess revolves around the two
Kings, with the main objective of each
player to deliver checkmate. A common
misconception of the King being open to
capture or exchange is still widespread.
Being the most important piece in the
game, the King is by definition also the
most vulnerable piece, and especially in
the opening and middlegame phases of the
game. In these phases, the King rarely
plays an active role.
The purpose of this survey is to study a
collection of games and game fragments
(source: ChessBase Mega Database 2011),
which addresses an additional less known
power of the King - to personally deliver
checkmate by move. As is with all
checkmates, a single piece is unable to
checkmate the opponent's King, if not
assisted by at least one other piece, either
own or opponent's, emphasizing the
importance of teamwork among chess
pieces of both colours.
Historical notes excerpts (source:
Piceclopedia):
- Except for some differences in special
moves, the King has remained the same
from its earliest days to modern-day Chess.
- The King has always moved one space in
any direction.
- In Chaturanga, which is widely regarded
as the earliest form of Chess, the King was
called a Rajah, which is Sanskrit for King.
- The Persians called it by the own word
for King, which was Shah.
- "Checkmate" comes from the Persian
expression "Shah Mat", which literally
means that "the King is ambushed".
- Reports that checkmate means "the King
is dead" are mistaken.

Lasker E. : Thomas G. A.
London 1912

Year 2012 will mark the 100th anniversary
of one of the most well-known master
games played in the history of chess.
Coincidentally, this game also features the
main theme of this survey.
Edward Lasker was born in 1885 and was
reportedly a leading German & American
chess player. He won 5 US Championships
in the period 1916–1921.
In 1973, as a 9-year-old, I had the honour
of meeting and playing Edward Lasker,
while at a visit to his apartment in New
York City. My mom reminded me he said
I was good ... Afterwards he had
recommended me to join the Manhattan
Chess Club, the 2nd oldest chess club in
the USA, which I did.
Sir George Alan Thomas was born in 1881
and was twice (1923 & 1934) British chess
champion, a 21–time All-England
Badminton champion, and a semifinalist of
the men's tennis doubles at Wimbledon in
1911.
1.d4 e6 2.Sf3 f5 3.Sc3?! Sf6
3...d5! would have made the c3-Knight feel
awkward.
4.Lg5 Le7 5.Lf6? Lf6 6.e4
A concept pretty difficult to understand if
not looking far enough. White gives away
their Bishops pair, and immediately
follows up with opening the centre, an
opening which should sooner or later
generally favour the Bishops.
6...fe4 7.Se4
What motivated Edward Lasker for his
previous two moves? The powerful central
position of the e4-Knight "guarantees"
White is ok. To chase the Knight away,
with for example p-d5, would result in a
vulnerable backward e6-pawn and a
potentially strong e5-square for White. To
eliminate the Knight, Black would either
have to give up their Bishops pair, too, or
manouever the b8-Knight to for example
f6-square, which in turn would mean
displacing the e7-Bishop to a worse
position.

7...b6!? 8.Se5?
White violates yet another opening
principle, whereby one should not play
twice with the same piece in the opening
phase of a game. Se5 falls into the category
of what sometimes I like to refer to as
"smart chess moves", ones with a threat.

Edward Lasker commented: "Black has
just played De7 in order to protect the mate
which was threatened by Sf6, followed by
Dh7. If in the position of the diagram
White played Sf6, Black would retake with
the Pawn, thereby protecting the pawn h7
with his Queen. However, White can force
the mate with a neat Queen's sacrifice
which drives Black's King right into the
arms of the remaining White pieces."

Edward Lasker: "The King cannot go to h8
on account of Sg6 mate. White now
continually checks Black's King in such a
manner that he has only one square to go to
until he is finally driven to the first rank,
all White pieces participating in the chase."
12...Kh8?? 13.Sg6#. Edward Lasker: "In
answer to Sg4 Black would play Kh5, Lg6,
Kh4, g3, Kh3 and there is no mate."

checkmate). 13.Sfg4? Kh5! (13...Kg5??

Lasker checkmated, Thomas said, "This
was very nice." Lasker, who had yet to
learn English, was touched by Thomas's
sportsmanship after a spectator translated
Thomas's remark into German for him. In
his "Chess & Checkers - The Way to
Mastership"

Edward

Lasker

wrote:

"Sacrifices made with the view of a direct
mating attack are, as a rule, the easiest to
figure out, as there is no guesswork
connected with them. In those cases the
player does not face the question as to
whether the position attained after the
sacrifice will be strong enough to insure a
gain of material at least equivalent to the

amount of material sacrificed, a question
which to answer correctly sometimes
requires a good deal of instinct trained by
experience; all that is necessary if to
ascertain whether the opponent can be
mated in a definite number of moves or
not. If the mate cannot be clearly foreseen,
the sacrifice must not be made. The
possibility of a sacrifice with consequent
forced mate is always indicated if a greatly
superior force is available for attack at the
part of the board where the opposing King
is located." 18.0–0–0# The King (move)
checkmates! 1:0.
