+AI & Rook
In chess, the rook is not the most complex piece.
It does not move diagonally, it does not jump, and it does not surprise.
Yet in many games, the rook quietly decides the outcome.
I believe +AI plays a similar role in today’s world.
+AI as a Rook
The rook moves in straight lines—horizontally and vertically.
Its strength lies not in creativity, but in reach, consistency, and speed.
+AI behaves in much the same way.
It does not replace human intention or strategy.
Instead, it extends them—across space and across time.
In practical terms, the effective use of +AI can be summarized into two main forms:
• Horizontal expansion
• Vertical expansion
Horizontal Expansion: Reusing Success Across Markets
Horizontal expansion means applying a method that worked in one domain to another domain.
In investment terms, this could mean:
• Taking a strategy that worked in equities
• Testing it in FX, commodities, or other markets
With +AI, this process becomes closer to:
• Copy & paste
• Then adjust parameters
What used to require deep domain-specific expertise can now be reframed as:
• Volatility differences
• Liquidity differences
• Time-scale differences
Markets stop being isolated worlds and start becoming parallel test environments.
The key point is not that every strategy works everywhere,
but that the cost of trying becomes extremely low.
Vertical Expansion: Compressing Time with Fast PDCA
Vertical expansion refers to speed.
More precisely, it is the ability to run the PDCA cycle—
Plan, Do, Check, Act—at high frequency.
Before +AI:
• One cycle might take weeks or months
• Human judgment and emotional delay were unavoidable
With +AI:
• Hypotheses can be generated, tested, evaluated, and revised continuously
• The cycle shrinks to hours or even minutes
This is not just “working faster.”
It is turning time itself into a form of leverage.
Investment as an Example: Same Returns, Different ROI
Consider a simple example in financial markets.
Traditionally:
• A non-AI investor with large capital might earn a stable return
• A smaller investor earns proportionally less, even if the return rate is similar
However, with +AI:
• Two investors may achieve similar returns
• Yet the capital invested and the trial-and-error cost differ significantly
As a result:
• ROI diverges
• Not because one investor is “smarter,”
• But because one investor operates with a more efficient structure
The +AI investor spends less to learn, less to fail, and less to adjust.
Competitive Differences Appear Gradually
This difference does not explode overnight.
At first:
• Both investors appear to perform similarly
Over time:
• The AI-enabled structure compounds
• Missed opportunities accumulate on the non-AI side
• Flexibility and adaptability begin to matter more than sheer capital size
Eventually, the gap becomes visible—not as a sudden collapse,
but as a gradual loss of competitiveness.
Closing Thoughts
+AI is not magic.
It does not guarantee extraordinary returns.
But like a rook in chess, it:
• Controls space (horizontal expansion)
• Controls time (vertical expansion)
• And quietly reshapes the game
In an era where +AI has already become a form of modernization,
the real question is no longer whether to use it,
but how long one can remain competitive without it.
Just as in chess, ignoring the rook is rarely a winning strategy.

Vertical expansion, on the other hand, means accelerating the PDCA cycle with +AI, reducing verification costs, and above all, saving time.
