Mouse Slip in 1858 || Morphy vs Löwenthal

Start the Morphy Saga here

This is the story of the birth of modern chess - when the possibilities of chess as an art, a science and a sport all converged.
The point of convergence was a young boy from Louisiana named Paul Morphy. At a time when America was seen as a backwoods nation with little cultural history and even less intellectual impetus, at a time when chess was considered the exclusive property of a few European countries, at a time when the game was played successfully by a handful of men wizened by years, Paul Morphy, in the brief span of 19 months and with seemingly little effort, defeated conclusively every player he met.
While today few non chess players even know his name, he was one of the most famous celebrities of his time and within the hallowed halls of the chess playing community he is considered by some as the greatest chess player of all time.
But this diminutive, unassuming boy rose to fame almost out of nowhere and once he secured his place in history, he retired back into that hazy unknown, shunning the public eye, never again to play serious chess. Not only was he one of great practitioners of the game, but also one of it's greatest enigmas. He's been given the sobriquet, The Pride and Sorrow of Chess.

    It was indeed a mouse slip, when an actual mouse jumped onto the board as Lowenthal moved his piece, leading to the mouse hitting his hand in mid-air which caused the mouse to slip on the board. The event was caught on video in 120fps slow motion and is considered Top Secret by the FBI.

    At the position where he resigned, what happens if white plays dark-squared bishop to D3? The checkmate is defended, black's rook is under attack and once white's rook is captured, the queen captures the knight. So worst case, you lose your Rook.

    “What kind of mouse slip can occur in 1858”? This wasn’t exactly an era of cleanliness... toilet buckets were emptied onto streets, disease was everywhere... during Morphy’s turn, Lowenthal stood up to clear his head. When it was his turn to play, he walked toward the board, arm outstretched, and just as his fingers grazed his chosen piece... he stepped, and in turn slipped, on a little mouse who had been scurrying around the playing area. His piece was accidentally pushed to the wrong square, and this is how we got the term “mouse slipped”.

    Why shouldn't he play Bd4 on the move resigned? That would stop the checkmate and also attack the Rook

  73. David Anderson

    David AndersonΠριν μήνα

    Alternate theories for the seemingly inexplicable h4 by Lowenthal: 1. Lowenthal was suffering from the early onset of COVID-1858. 2. Lowenthal had just finished watching a series of blitz games by Simon Williams and was just way too eager to throw Harry into the fray. 3. The h-file was Lowenthal's main plan for getting his rooks into the attack, but then he became distracted by Morphy's casual demeanor and somehow completely forgot his plan. 4. He thought he could trap the knight with a poisoned pawn but didn't think it through. As intriguing as the first three theories are, I'm going with #4.
