Hi everyone!
I've just released a free English demo of Живият Ум (The Living Mind), an interactive edition of my father Vladimir Bostandzhiev's book. Alongside his other books, this is part of his life's work, and this is our family's first step toward sharing it directly with readers in a digital format.
Try the demo here: https://boristhoris.itch.io/zhiviyat-um
This is a demo, not the full book: one complete chapter, The Scissors Principle, and two optional chess Labs. It runs in your browser on desktop or phone.
I'd especially love feedback on the Labs system. The idea is to move from reading a passage to exploring a position, making a decision, seeing the evidence, and returning to the exact passage. In the longer Lab, you can form a first impression, test legal queen replies, then decide whether to take or leave a pawn. The shorter Lab asks you to choose a pawn by its route toward a goal.
I'm trying to make these interactions useful and engaging, and I'd be very happy to receive more feedback on how to make them better:
• Did exploring the board help you understand the idea in the chapter?
• Were the controls, available choices, and consequences clear?
• Did the Labs give you enough room to investigate, or did they feel too guided or too shallow?
• What would you change, add, or remove?
Even a short first impression would help. If something feels confusing or breaks, please tell me which Lab you were in, what you tried, and whether you were using a phone or desktop. I'd also love to know your level of chess experience so I can understand where the design needs to improve.
Thanks for taking a look and helping us make this better!
