Half a story
Some things in chess are very concrete and visible -- checkmate, or
a
knight fork, perhaps, or as we get better, we can also see superior
development or pawn weaknesses. There are more abstract features
of a chess game which are less easy to see, at least at a glance, and
you can appreciate best over a whole game or a part of a game.
Annotators often talk about a player's '
Steinitz became World Champion (more or less) in 1866 by beating Adolf
Anderssen in a bloodthirsty match (+8 -6 =0). His style was very
much in the tradition of the Italian school, playing for attack from
the word go. He was awarded the brilliancy prize for this Rook
sacrifice:
Romantic Steinitz (up to and including 1872) (304)
This session comes out of a remark by ex-World Champion Tigran
Petrosian, to be found in an excellent book, 'Opening
Preparation' by Mark Dvoretsky and Artur Yusupov. In the
middle of annotations to a game by Henrique Mecking in 1972 the
authors quote Petrosian:
"Mecking does not understand the significance of
weak and strong squares. I have played him three times. In 1969 he
lost to me owing to the weakness of his light squares. A year later
Knights like outposts, bishops like clear diagonals: you
could guess that rooks like clear ranks and files. The best rank to
put your rook on is the seventh, particularly if the opponent's
king is trapped behind it. A rook on the seventh rank (or 'on the
seventh' as people sometimes say) can threaten unmoved pawns and
with assistance can create mate threats. To get to the seventh the
rook will have to move along a file. You can see Znosko-Borovsky
doing just that with the c-file in the Illustrative Games. The
other use of rooks on files is to attack: we have seen some
The King's-side attack is so exciting and pleasurable that it is
sometime hard to remember that games can be won on the other side
of the board. I can remember some youthful indignation when playing
against the French Defence, when my ambitions on the King's-side
came to nothing, while my opponent's pussyfooting manoeuvres snuck
in for a touchdown on the neglected Queen's-side.
What is there to aim for in a queen-side attack? The aim
is not mate, but to win or weaken the opponent's pawns on that
side. Queen's-side attacks are more modest but more safe than
I will give several illlustrative games here - fairly
straightforward games from Capablanca, Alekhin, Korchnoi and
Karpov showing pawns mobile and dangerous, and the others (e.g.
Nimzovitch's) showing them stuck and vulnerable.
"The most important feature of the chess position
is the activity of the pieces. This is absolutely fundamental in
all phases of the game (opening, middlegame and
especially endgame). The primary constraint on a
