London System: a practical example
White often develops the dark-squared bishop before completing a supporting e3 and c3 structure. Familiar piece placement can reduce some opening memorization, but Black's setup still changes the best move order, pawn breaks, and tactical possibilities.
How to use the idea in your games
Use the setup as a starting framework rather than an automatic script. Check threats and central tension every move, especially when Black develops actively or challenges d4 early.
A useful study question
Can you explain london system in your own words, identify it in a position, and describe when the idea does not apply? Test the explanation on a legal board before relying on it.
