Opening traps
'A trap is the provocation of a mistake. A trap always involves a tempting or obvious reply by the opponent. He is more or less invited to make an apparently good move, but one which is rapidly and surprisingly refuted.'
- Neistadt
There are players who try to tempt their opponents into a trap right in the opening, hoping to win the game without any real effort. They simply learn specific variations and do not bother with the main systems.
Benign traps
If a trap is simply a by-product of natural development and in no way hinders future logical development, then we can call it a benign trap.
There is nothing wrong with opening traps. They too extend our knowledge of theory and form part of the whole concept of development.
Bad traps
But sometimes players try to set opening traps which are dependent on one single reply by their opponent. If the opponent spots the trap and plays something different, then the consequences are disadvantageous for the 'poacher'. We shall call opening traps like that bad traps.
It is not worth playing for such traps, since there is a great danger that your opponent will either spot them or know them. In any case, an opening repertoire for the long term should be constructed on solid foundations and not on a reliance on bad traps.
How do you spot a trap?
In general, you have to react very cautiously whenever your opponent suddenly offers material in the opening. Calmly check through all your opponent's active moves. By doing so you will probably soon discover the trap - if there actually is one.
You should be on your guard particularly when playing gambits, since they contain a lot of traps and ways to go wrong.
The pawn wedge
A pawn wedge is the name we give to a pawn which has advanced as for as the 6th rank.
We are particularly interested in achieving a pawn wedge in the neighbourhood of the opposing king, generally on f6, g6 or h6 (or, as Black, on f3, g3 or h3). Such a pawn restricts the mobility of the king, disrupts the defence and 'constitutes a favourable motif for mating attacks' (Kotov). It is often said that, when you are attacking, a pawn wedge is as strong as a minor piece, sometimes even stronger.
The pawn wedge is a powerful weapon. In your own games, try to strengthen an attack with the h- or f-pawn. In some circumstances you can also advance the g-pawn. But this operation is more dangerous if you have castled short, because it weakens your own king position.
