Even Grandmasters Slip Up: The Lessons of Blindfold Chess

It’s a truth that every serious chess player eventually learns: no one is immune to mistakes—not even grandmasters. The truth hits home especially hard in blindfold chess, where even seasoned masters can leave powerful pieces hanging in the heat of the moment. 

The Blunder of GM Pepe Cuenca

About two months ago, during a high-stakes blindfold exhibition, Spanish GM Pepe Cuenca—an experienced IM since 2006 and GM since 2015, with a peak rating of 2558—managed to blunder a rook. 

Yes, you read that right: a rook—in a totally normal tactical sequence—simply slipped from his mind as he visualized the position. The result? One of the few remaining rooks disappeared in a single moment of oversight. 

This incident earned some giggles across the broadcast, but the takeaway was serious: mental errors happen, even at elite levels, especially when playing without sight of the board. It’s a unique kind of pressure. 

 Why It Happens

  •  Load on the Mind: Blindfold chess requires memorizing and mentally updating every piece’s position—a heavy burden even for grandmasters.

  • Time Pressure + Complexity: In blitz or exhibition formats, rapid thought and recall can falter—especially in sharp, tactical lines.

  • Human Nature: We’re fallible. Attention can slip, focus drifts, and even top-tier players miscalculate.

 What We Can Learn

  • Accept Mistakes: Every player faces them. Seeing a GM slip up brings us all down a notch—or two—from perfection.

  •  Focus on Essentials: The board remains visually present for a reason. Use all senses available.

  •  Learn from Oversights: Whether it’s a lost rook or a missed tactic, mistakes are training gold—analyze them, internalize the lesson, and grow stronger.

 Conclusion

Next time you stumble upon a blunder—whether you miss a fork , drop a piece, or missmate that was staring you in the face, remember: even grandmasters like Pepe Cuenca do the same. ♜♞

Chess is a mental sport, and the greatest lesson is resilience. We miss a move, recalibrate, and continue to play on.
