Create Engaging Chess Game Tutorial

I’m looking for a freelancer to help create a beginner-friendly tutorial for my mobile chess variant game before launch.

The game is based on chess, but it includes custom mechanics and a unique piece called the Trader, so I need someone who already understands chess well enough to explain differences clearly and simply.

What I need:

- A clear tutorial/onboarding flow for first-time players
- Beginner-friendly explanation of how my game differs from standard chess
- Suggestions for the best tutorial format (guided tutorial, pop-ups, help page, short video, or combination)
- If you are technical, ability to help implement the tutorial in an existing app is a plus

Ideal person:

- Strong understanding of chess
- Experience with game tutorials, onboarding, UX writing, or explainer content
- Able to simplify complex rules without confusing users
- Bonus if you have experience with Flutter or mobile game UI/UX

Please reply with:

1. Your chess experience
2. Any tutorial/onboarding work you’ve done before
3. How you would approach teaching a custom chess variant to a brand-new player
4. Whether you would recommend in-app onboarding, video tutorial, or both
