About

I'm Saber. Two boards run my life. On one of them I push a pawn to d4 and try to control the center — I'm a ~1900 positional player, Stonewall as White, more interested in structures than fireworks. On the other board — an electrode montage — I do a PhD in EEG and brain-computer interfaces in Marrakech, trying to pull usable signal out of noise.

Why "d4"

d4 is my first move. It's also, quietly, a brainwave: the slowest EEG rhythm is the delta band, which runs from about 0.5 up to 4 Hz. d, up to 4. One name, both boards. That's the whole joke, told once — the logo is a board quadrant whose top-right square is d4, with a single slow delta cycle drawn through it.

Why "Lab"

Because this is not a masterclass. A lab runs experiments, and experiments fail — the interesting part is the protocol and the postmortem. I publish the plan, the result, and the gap between them: the lost games with the eval graph attached, the model runs that went nowhere, the study systems I abandoned. If you're looking for someone certain, there are other websites.

What gets published

Three threads, one mind: chess breakdowns that care about why a plan works rather than what the engine says; EEG/BCI explainers written for people who like precision but don't have a signal-processing degree; and method pieces about how the studying actually gets done — the same systems-thinking whether the position is on a board or in a dataset.

The promise

Working shown. Uncertainty stated. Nothing sold. If I'm wrong somewhere, tell me — that's the fastest way this lab produces anything.
