Using Obsidian as a Chess Game Database

The Trading Parallel Chess and trading share a fun truth: you can spend hundreds of hours practicing and still lose. In trading, it’s capital. In chess, it’s ELO. Both require deliberate review of past mistakes to improve. Traders keep journals. Chess players should too. I’ve found that Obsidian—a tool I already use for notes—works perfectly as a chess game database.

Inefficiencies, bugs (bad habits), suboptimal resource allocation – it’s all there. Journaling is essentially running diagnostics, creating log files to analyze performance and identify areas for refactoring. Different methods act like different logging levels or diagnostic tools, each with trade-offs in terms of overhead (time) and output (insight). The goal isn’t just passive observation; it’s active optimization....

Critical Thinking in the Age of AI: Why Your Brain Is Your Last Competitive Advantage

The Calculator Effect, Amplified Remember when calculators became ubiquitous? Teachers worried we’d forget how to do mental math. They were right—but it didn’t matter much. The trade-off was acceptable. Generative AI is making the same bargain, except this time we’re not trading away arithmetic. We’re trading away thinking itself.
