The Bishop's Ledger
Issue 214 · Annotated Classics
Study No. 07 — Paris, 1858
Paul Morphy plays the Duke of Brunswick and Count Isouard during a performance of Norma. Every developing move points at one square; every defensive move costs a tempo. Step through the ledger and watch the evaluation rail tilt.
Starting position.
Long form
A lesson in the arithmetic of tempo
There is a temptation to read this game as a magic trick, and the Duke and the Count as the volunteers pulled from the audience. That reading is generous to Morphy and unfair to the position. Nothing here is conjured. Every piece he moves goes to a square from which it looks at the black king, and every piece he gives away buys him a move that his opponents cannot answer.
Count the developing moves after move nine and the game is already decided: White has four pieces in the attack and a rook waiting to join; Black has a bishop that has been traded for a knight and a queen doing custodial work on e7. The pawn grab on b5 is not greed — it is the only way to open the file that the rook will eventually walk down.
What makes the finish memorable is not its length but its inevitability. From move thirteen onward Black has legal moves and no choices. The rook sacrifice on d7 removes the last defender who could have complained; the queen offer on b8 removes the second. The mate is delivered by the piece that was developed last, which is a very Morphy sort of joke.
Key square
d7. Four white pieces touch it before the rook ever lands there. Black never once contests it with a pawn.
Turning point
9…b5. Understandable, losing, and the move most club players still play in this structure.
Takeaway
Material is a currency for time. Spend it only when the purchase is a forcing move.
