But for a few years, in the pockets of chess enthusiasts, there lived a ghost. A ghost that turned a mundane commute into a humbling lesson, that drained your battery in exchange for positional truths, and that proved one thing: the future of chess belonged not to bulky boards or desktop towers, but to the silent, burning-hot computer in your hand.

It would offer a pawn, let you take it, and then slowly, mercilessly, tighten a positional vise until you realized your queen had nowhere to go.
