\section{Steinitz' rules of attack (from Kotov/Chernev)}


\begin{enumerate}

\item
 In chess, only the attacker wins.  Defenders win only when the
attacker makes a mistake, OR if the attacker had no right to attack in
the first place. Even then, the defender must become the attacker to
win. 

\item
 The right to attack belongs only to that side which has the better
position - a positional advantage of some sort.

\item
 If you have the advantage, you have not only a right to attack, but
also a duty to attack, otherwise there is the risk of losing the
advantage. 

\item
 The attack is to be directed against the weakest spot in the
opposing position. 

\item
 The defending side must be prepared to defend and make concessions,
or take a risk and try a counter-attack.

     \item
 An attack undertaken without sufficient positional basis
must be repelled with best play, and will lead to a disadvantage for
the prospective attacker.
\end{enumerate}

          



\section{Vukovic's Guidelines for attack}

\begin{enumerate}


\item
If you attack the king, make sure that either your opponent cannot
counterattack, or at least that your attack is more quick or more
dangerous. 

\item
So, you must look at the whole board, and the chances for both
sides, when deciding whether to attack or not. 

\item
Security in the centre lends support to a wing attack.  A central
pawn blockade prevents or limits counter-attacks, and makes a pawn
attack easier. 

\item
This is particularly true of attacks with pawns, which must creep
forward more slowly than other pieces.  If you can make an attack with
pieces alone, leave your pawns at home. 

\item
If you already have a pawn advanced, e.g. to f5, which may block
your bishop on the diagonal b1-h7, then you might be better off going
for a pawn storm by advancing the g-pawn. 

\item
As a rule, it is difficult to break through with pawns against the
unweakened castled king's position.  This is because the pawn wave can
be blockaded. 

\item
So, it is usually important to weaken the castled position first
(e.g. by ganging up on h7 you might force ...g6 or ...h6). 

\item
Pawns don't half get in the way of rooks.  If you cannot open a
file, you can often get your rooks into action in front of your pawns,
for example, by playing them to the third rank. 

\item
Pawn advances loosen your position, and may be a disadvantage in
the ending. 

\item
Although you must be careful before starting an attack, once you
have started you must go in as hard and fast as you can.  This is even
more important if you realise you shouldn't have started the attack
quite yet - if you try to back out you will only make things worse. 

\end{enumerate}
