Definition: The term sums up the science of winning a won game where creativity and imagination play a minor role. A 'technical' position is the kind that might be used in an endgame manual to illustrate a particular method of winning without examining all of the subvariations.
Technique also refers to the skill required to pursue a win while preventing the opponent from developing any meaningful counterplay. Good chess players usually display good technique.
An annotator often writes, 'the rest of the game is a matter of technique', providing no additional comment. This means that one player has such a great advantage that the win is a matter of time, e.g. creating a passed Pawn and pushing it to promotion.
