The London System is an opening system in chess where White opens with 1.d4 and develops the dark-squared bishop to f4, then supports the d4-pawn with pawns on e3 and c3. The other bishop is developed to d3 (or occasionally e2) and the knights typically to f3 and d2. This set-up often results in a closed game. The London System can be used against virtually any Black defence and thus comprises a smaller body of opening theory than many other openings. Although it has a reputation as a solid opening, the London System has faced criticism for its tedious nature and lack of dynamic play.[1][2][3][4][5][6]
The rapid development of the dark-squared bishop in the London System can be contrasted with the Colle System, in which the queen's bishop typically remains on c1 during the opening phase of the game.[7]

If someone wants to play the London System, you have to recognise that the game's going to be pretty quiet for a long time.

White's play rather resembles some kind of solid and fairly unthreatening Slav!

Due to [its] rather schematic approach, the London 'enjoys' the reputation of being a dull and unambitious opening: 'It's always the same, how boring!'
