From the history of 3D chess to Sheldon Cooper’s wonderfully complicated three-player version, this article is my imagination of what might happen if Sheldon faced Magnus Carlsen. We’ll even look ahead to a future where 3D chess is the tournament standard, and Chess960 gets an extra dimension. Sounds very complicated, right?
A Brief History of 3D Chess
3D chess wasn’t invented for The Big Bang Theory. Chess players and inventors had been experimenting with multi-level boards for more than a century. One early version, Raumschach (“space chess”), was developed in Germany in the early 1900s. Later, Star Trek made its futuristic stacked chessboard famous, and fans developed rules to make the prop playable. Sheldon playing 3D chess helped keep the idea in pop culture, introducing a new generation to the game even if most of us know it mainly as a sign that someone is very, very smart.

Another interesting fact is that, in the show, Sheldon also invents 3-player chess with unusual pieces called "the serpent, the old woman and the grand empress." The serpent could “poison” an opponent’s piece: after the serpent moved next to it, that piece would die two moves later unless it reached the Old Woman in time. She could remove the poison, then transform into the Grand Empress, which combined the powers of a knight, queen, and serpent. Sounds so complicated but super fun. Would you consider playing that?

Meet the Players in 3D Chess Match
In one corner is Magnus Carlsen, the Norwegian grandmaster and former world champion. He’s known for finding winning chances in positions that look completely even.

In the other corner is Sheldon Cooper, the theoretical physicist from The Big Bang Theory. He’s brilliant, socially awkward, and overly confident. Sheldon tends to treat a casual game like a championship match, especially when he thinks the other person has made a mistake.
The Post-Match Interview
If Sheldon lost (which he probably would), he might have a few explanations ready. Maybe the rules weren’t clear. Maybe the board was badly designed. Maybe the lighting was distracting. Or maybe Magnus was sitting in his spot or breathing too loudly.

He’d probably ask for a rematch under proper conditions, which could involve a new board, a new chair, or a very detailed review of the rulebook, or he might deem the entire idea of chess stupid. Typical Sheldon behaviour.
The Verdict
Magnus is more likely to win the game. Sheldon, however, might win the post-match argument because he is super annoying and stubborn. He would demand a rematch and insist it happens in his spot.
Could 3D Chess Become the New Standard?
So much talk about 3D chess led me to imagine: what if, a hundred years from now, 3D chess was the new norm? Imagine it’s 2126 and every serious chess tournament is played on a multi-level board. It’s possible, especially if a version becomes easy to learn, enjoyable to watch, and simple to play online. Chess has already survived queens that move in every direction, clocks that make everyone panic, and people saying “I had that” after losing in six moves. A few extra floors might be manageable. Maybe?
If 3D chess became the norm, the best player probably wouldn’t simply be today’s strongest standard chess player. Carlsen would have a strong starting point: pattern recognition, calculation, and years of experience would all help. But players who grew up with the 3D version might develop instincts for its extra dimensions that today’s players don’t have. The commentary might sound like: “The knight has moved upstairs, the bishop is cutting across the atrium, and the rook has been asked to stop blocking the lift.”

And yes, it could have a Chess960 version. Chess960 changes the starting arrangement of the pieces while keeping the rest of the rules mostly the same. A 3D version could randomise the starting positions across its levels, too, as long as the rules were designed to keep each setup playable and fair. Would it be too complex? Maybe. It definitely does sound like too much, but maybe, just maybe, a fun variant to try.
