AlphaGo’s Unseen Genius Move | Generated by AI
Question: What makes Move 37 special in AlphaGo?
Answer:
Move 37 — AlphaGo’s Most Legendary Play
Context: What Was the Match?
Move 37 refers to a move in Game 2 of the 2016 match between Google’s AI Go program AlphaGo and Lee Sedol of South Korea — a 9-dan player and one of the best, if not the best, Go player in the world at the time.
What Exactly Was Move 37?
This move — a shoulder hit on the fifth line — was unexpected and initially baffled both the commentators and Lee Sedol himself. Traditionally, such a move would be considered unconventional, if not outright suboptimal, by human standards.
Move 37 caused one of the English-language live commentators, top Go player Michael Redmond, to squint in disbelief at the match’s live video feed. “That’s a very surprising move,” he said, pivoting back and forth between the board and the monitor to make sure he had not gotten it wrong. At that moment, a clearly rattled Lee Sedol left the room; he returned a few minutes later and took 15 minutes for his next move.
Why Was It So Special?
1. Statistically Almost Impossible for a Human
In Game 2, AlphaGo played Move 37 — a move that had a 1-in-10,000 chance of being used by a human player. This pivotal and creative move helped AlphaGo win the game and upended centuries of traditional wisdom.
2. Completely New to Go’s History
The strategy that AlphaGo built around Move 37 was not taken out of a database of publicly known moves. Move 37 was new to the 5,500-year history of Go. It belonged to a style of play that Go commentators sometimes called “inhuman” and “alien.”
3. Not Programmed — Emerged from Self-Play
AlphaGo came up with this move not because it was a strategy directly programmed by the Google team, but because of reinforcement learning and self-play — it was able to see this move as the best move to meet its objective of winning. Interestingly, AlphaGo is not trying to maximize its lead at specific moments, but instead is looking for its best chance of winning, even if that win is by a small margin.
4. Broke Human Cognitive Constraints
Human Go players, even at the professional level, are influenced by centuries of established strategies and heuristics. These heuristics, while effective, can also constrain creativity and limit the exploration of unconventional moves. AlphaGo, unburdened by these historical biases, was able to evaluate the game from a fresh perspective, leading to innovative strategies.
5. Demonstrated Genuine Strategic Creativity
Move 37 was the ultimate power move, a testament to AlphaGo’s ability to analyze, adapt, and innovate. This wasn’t just a computer playing by the rules; it was a machine exhibiting genuine strategic creativity. AlphaGo’s AI peered into the complex tapestry of the game and saw an opportunity that had completely eluded Sedol and the Go establishment.
The Broader Impact
AlphaGo’s victory inspired a new era of AI systems. It was conclusive proof that the underlying neural networks could be applied to complex domains, while the use of reinforcement learning showed how machines can learn to solve incredibly hard problems for themselves, simply through trial-and-error.
Even Lee Sedol himself changed his mind about AI after witnessing the move, reportedly saying: “I thought AlphaGo was based on probability calculation and that it was merely a machine. But when I saw this move, I changed my mind. Surely, AlphaGo is creative.”
A Counterpoint Worth Noting
It is unknown whether Move 37 was a software error or a rare misstep in an otherwise perfect game. Alternatively, it could have been an example of superhuman play — a brilliant insight made by a machine unrestricted by social convention. No matter what the reality, Move 37 condenses the complex undecidability of machine creativity into a single moment.
