What Is Shah Kur and How Does Its Blindfold Chess Training Work?

Shâh Kur is a free browser-based blindfold chess training app that helps you improve board visualization and memory. It is aimed at players who already know how the pieces move and want to practice seeing the board without relying on visible pieces. The app runs on the site shahkur.specr.net and requires JavaScript to play. Its core tools are blindfold play, a fade mode, voice move entry, board memory games, and AI opponents powered by Stockfish.

What Shâh Kur Is For

Blindfold chess means playing without seeing the pieces, or with pieces that are hidden or removed from view. It is a visualization exercise: you have to track where every piece is in your head. Shâh Kur turns that exercise into a trainable routine rather than a one-off challenge.

The app is built around two related skills:

• Board visualization — knowing where pieces are and how they interact without looking.
• Position memory — holding a specific arrangement of pieces in mind and reproducing it.

If you are new to chess, this is not a learn-the-rules tool. It assumes you can already read algebraic notation and follow a game.

How the Training Features Work

Blindfold Chess

You play against an AI opponent with the pieces invisible. You still make legal moves and receive the opponent's replies, but you cannot see the board state directly. The point is to maintain the position in your head and calculate from there.

What you do: start a game, then enter moves as you would in a normal game. What you get: feedback on whether your mental model of the board holds up as the game progresses.

Fade Mode

Fade Mode is a gradual version of blindfold play. Pieces start visible and disappear over time, so the difficulty increases as the game goes on. This is useful if full blindfold play is too hard at first: you begin with normal sight and are pushed toward visualization step by step.

Voice Control

You can make moves by speaking algebraic notation instead of typing or clicking. This keeps your hands off the board and reinforces notation recall, which matters because blindfold play depends on translating notation into a mental image quickly.

Board Memory Games

These are separate exercises where you memorize a chess position and then recreate it. They train the same recall skill that blindfold play demands, but in a shorter, more focused format.

AI Opponents

Games are played against Stockfish, with difficulty ranging from casual to master level. That range lets you separate two variables: you can practice visualization against a weak opponent while you are learning, then raise the level once the mental tracking becomes easier.

Feature Summary

How to Decide Whether to Use It

Shâh Kur fits you if:

• You already know chess rules and algebraic notation.
• You want structured visualization practice rather than casual play.
• You prefer training in a browser without installing anything.

It may not fit you if:

• You are still learning how pieces move.
• You want to analyze games with a visible board and engine lines.
• You need offline access — the app runs in the browser and requires JavaScript.

The site describes the app as free. No pricing links or payment platforms are listed in the available material, so treat that as the stated model rather than a confirmed long-term guarantee.

A Practical Way to Start

1. Open shahkur.specr.net and enable JavaScript.
2. Begin with Board Memory Games to warm up position recall.
3. Move to Fade Mode against a casual AI opponent so pieces vanish gradually.
4. Switch to Blindfold Chess once fade mode feels manageable.
5. Use Voice Control if typing moves breaks your concentration.
6. Raise the Stockfish level only after you can hold the position at the current level.

The main checkpoint is simple: if you can finish a game without losing track of where your pieces are, the training is working. If you lose the position repeatedly, drop back to fade mode or a lower AI level rather than pushing through.
