Paul Morphy

Step through the game; it stops where a move is worth finding.

Before move one

Coach

Edward Lasker presents Morphy's famous consultation game as a study of mobility and the compounding cost of lost time. His explanation follows one continuous causal thread: Black's early choices obstruct development, each threat then demands another passive move, and Morphy invests material because the undeveloped pieces cannot participate in the defence.

Engine plan

Track which pieces each move releases or obstructs; a defended pawn can still be strategically expensive.
When ahead in development, compare taking material now with preserving the threats that force more passive replies.
Before sacrificing, look ahead to which enemy pieces can actually reach the opened lines in time.
