Ok potong gaji for missing one content worth posting last September 2025 of the Malaysian Chess Festival. 

I didn't even get a picture of her during the festival event at KL Gateway where she showed up multiple times presumably to see how her student was getting on. Here's some old pix of her...

Younger sister of WGM Irene Sukhandar - WIM Diajeng Theresa Singgih was here as I bumped into her at the start of the festival. Was surprised that she was not participating in any of the festival events at all. She was here to coach her Malaysian student. Well that was all I got from her when I talked to her. I assume that the student was a remote student and the festival was a chance for a face-to-face with the coach.

The May 2026 FIDE rating list shows Diajeng Theresa Singgih is no longer just a "prospect" but a dominant force in Southeast Asian chess. Her climb from 7th place in April to 2nd place in May among Indonesian women is a more than impressive.

The Numbers: A "Quantum Leap"

• Current Rating: 2308 (Standard FIDE Rating).

• Rank (Women/INA): 2nd, trailing only IM Medina Warda Aulia (2355).

• April-to-May Jump: She gained nearly 200 Elo points in a single month after a whirlwind of international competition, effectively overtaking seasoned veterans like WGM Chelsie Monica.

Also note that her older sister is not in the list because she was inactive for a year.

The "India Effect": Sharpening the Blade

Following in the footsteps of Grandmasters who seek the "trial by fire" found in the Indian chess circuit, Diajeng spent significant time in India between 2025 and 2026.

• Playing Indiais crazy!
  India is known for having "underrated" youngsters. Playing there is notoriously difficult for one’s rating. It takes courage and confidence for anyone trying gain ELO points playing in the shark infested waters of India.

• Notable Scalps: During her 2026 run, she secured a stunning victory against GM Pouria Darini (2458) and a solid draw against Vignesh B (2222), proving she can hold her own against much higher-rated male opponents.

The European Tour 

Her "solo travel" across Europe—a rare and courageous move for a young Indonesian player—was the catalyst for her recent success.

• Serbia Success: It was in Serbia where she secured her second WGM (Woman Grandmaster) norm. Three norms are required for the title; Diajeng is now just one norm and a sustained 2300 rating away from becoming Indonesia's next Woman Grandmaster.

• Financial Independence: Unlike many who wait for federation funding, Diajeng reinvests her earnings from prize money, coaching, and commentary back into her career. That's a big commitment and investment to one's own chess development.

A New Era for Indonesian Women's Chess

• National Impact: Her 2308 rating doesn't just place her 2nd among women; it places her 22nd overall in Indonesia (including men), a rare feat for a female player at just 22 years old.

Fun Fact: Diajeng is also a prominent figure in the digital chess community. Known by her handle @chezzgirl04 on Chess.com and active on Instagram, she bridges the gap between traditional professional chess and the modern "streaming/content" era, making her one of the most relatable ambassadors for the sport in Indonesia.

The oldest pix I have of Diajeng is this one when she was 10 years old in 2014.

That just shows how long chess has been part of her life! Of course she has been "in" chess a couple of years before this.

 She is now 22 years old.

How Chess Patterns Matter to Making a Smart Chess AI

So what if you got the strongest chess engines, the best databases like the latest Chessbase 26 with access to millions of games from Megabase 26. But these are tools accessible by any chess players as long as they have the money to get them. And they've been around forever.

The evolution of chess is stagnant. Databases and chess engines. Of course we have the chess authors and chess coaches peddling their books and chess courses from Chessables etc. Don't get me wrong, there is potentially tremendous value in those mediums - no questions about that.

It's the new technology that is lacking. For decades, the chess industry has prioritized "brute force" calculation—engines like Stockfish that see 40 moves ahead but lack the vocabulary to explain why a position is winning. 

What I feel is missing is computers understanding deeper. We need "smart" AI—one that truly assists human improvement—requires a shift from pure numerical evaluation to tactical pattern recognition.

That just means AI that recognises what is a fork, pin, skewer, discovered attack, double check, back rank weakness, colour weakness and double attack. Wait what? Don't computers already do that ? The simple answer is no. They can pin point which move in a game is a blunder or was brilliant but aren't that great at just recognising if the winning theme was a double check.

Beyond the Centipawn: The Language of Logic

Traditional engines see a board as a mathematical value, often expressed in "centipawns" (e.g., $+1.5$). While precise, this is a "black box" for the average player. A pattern-aware engine, such as the architecture behind ChessGrammar, transforms this math into a geometric map. Yes, there is only ONE project that does this as far as I know, called ChessGrammar (you can Google it to find out more).

By identifying the "grammar" of the game—forks, pins, skewers, and back-rank vulnerabilities—an AI can categorize positions instead of just scoring them.

This classification is the "missing link" in chess tech. When an engine identifies a discovered attack, it isn't just finding a winning move; it is identifying a specific logical theme. For a developer, this means the AI can provide structured data (like JSON) that tells a front-end application exactly what is happening. For the player, it means the feedback is no longer "play Be7," but rather "Be7 works because the Rook on d1 is pinning your Queen."

Patterns are the Secret Sauce!

Personalized Training Data: Imagine now you can pull out your database of games and ask the computer to list the games where there was a winning fork, but you missed it.

Machines that can "See"!

The smartest Chess AI for me isn't the one that wins every game—it’s the one that understands the shapes of the struggle, lets me learn from it. 

For the moment, ChessGrammar is closed source, although the programmer allows others to use it via API calls. That is not ideal as it seems that it is the effort of just one person, and his source code is personal, and I assume it is not shareable.

Ideally, someone should make a similar project but open-source it so that it can be improved on by multiple software engineers around the world.

For a couple of years I've been playing with the idea of AI chess coaches.

Why?

I don't have the money to pay a real coach! Call me cheap but I want a machine to teach me.

Of course there are materials out there one can use to improve like books, interactive digital courses like Chessable etc.

But these are general purpose marketed for profit to fit the general chess learning public. Everyone will agree with me if you had a personal coach, there would be leaps and bounds in chess improvement.

That's where a digital coach comes in. It's personal. It's available 24/7/ It's adaptable, learning from your good and bad habits. The ideal and perfect coach. And also improbable as if it was possible, someone would have already created in this fast moving age of AI tech.

I've posted many #syioksendiri posts on why it's not possible. At least not yet. But will be possible in the near future.

I think the future is now.

My initial thought was that you need a specialised Chess LLM - not those silly general purpose LLM like ChatGPT, Gemini, Claude etc which is great at many things but horrible at chess. Many still play illegal moves and cheat.

A new LLM based on chess would have been too expensive in terms of hardware, time and monetary costs.

The solution would be to use a free local LLM and do "fine tuning" - teaching it all it needs to know about chess so it can become good enough to commentate like a digital version of GothamChess. 

How?
By investing in the right hardware and choosing a good LLM.

Hardware Requirements

To achieve this, hardware investment will be on GPU VRAM.

• The "Sweet Spot": A setup with dual RTX 3090, 4090, or the newer 5090 cards (providing 24–48GB of VRAM) is ideal for running 8-bit QLoRA (Quantized Low-Rank Adaptation). This allows to fine-tune a powerful model like Gemma-4-31B, which is considered the "gold standard" for the linguistic nuance required for grandmaster-level commentary.

• Entry Level: A single RTX 4090 (24GB) can handle 4-bit LoRA, which is faster but may result in slightly less "fluent" coaching.

The Hybrid Architecture

It is critical to understand that even the best fine-tuned LLMs can hallucinate tactics or illegal moves. Therefore, the most effective feasibility path is a hybrid system:

• Chess Engine (Stockfish): Acts as the "source of truth," generating evaluation scores, best lines, and identifying tactical threats like blunders or forks.

• Fine-tuned LLM (Gemma 4): Acts as the "translator," taking the engine's raw data and converting it into enthusiastic, "Gotham-style" commentary that explains the why behind moves in plain language.

With this setup, the AI can perform advanced coaching tasks:

• Interactive Quizzing: The system can be designed to pause mid-game and ask, "What would you do here?", followed by an explanation of why the user's choice was correct or a mistake.

• Narrative Structure: Instead of move-by-move data, the AI can split a game into opening, middlegame, and endgame phases, summarizing the "narrative" of the match just like a human coach.

• Psychological Insight: By fine-tuning on human commentary, the AI can point out "panic" moves or "desperate" central lunges, making the learning process engaging rather than purely mathematical.

Training, Training, Training!

By leveraging open-source datasets from Lichess or Chess.com and using parameter-efficient tuning (QLoRA), we can (hopefully) create a professional-grade coach that runs fully offline on our own machine.

We'll feed it PDFs with high quality chess analysis and commentary and of course YouTube chess commentaries from top commentators like GothamChess and Sagar Shah (Chessbase India). I would not even to explain how"magical" this process takes place and many AI expert fail to explain how the machine learn from just looking at examples. Only that it works!!

For example Suno was fed with tons of songs and in the end, it learnt how to compose songs better than most humans. MidJourney was fed with the world's best photographers pictures and artists and it can now mimic photos and art that few can differentiate if it was from a professional photographer or artists - and the examples can go on and one. Suffice to say, given enough example data, the AI can mimic the expert to a high degree!

Of course it's going to take an investment in a PC with a good GPU or maybe some rented time on hosted GPUs at Amazon servers. This is the least of it! The biggest investment is time. The  humungous amount  of time to train, since we are not billionaires or startup and cannot afford data centres to create and learn from training data with expensive servers.

But the thing is, it is now feasible and possible.
