d4 Lab

Control the center.
Measure the signal.

One mind, two boards: a chessboard and an electrode montage. This is the lab where both get studied — plans, signals, mistakes included.

01 — the double read

One grid, two boards.

Drag the slider. The same 64 positions read as chess squares or as a 64-channel EEG cap. That double read isn't a metaphor bolted on afterwards — it's the reason this lab has one name instead of two.

02 — three experiments, one protocol

What runs in this lab.

CHESS

Structure-first breakdowns

The Stonewall, pawn skeletons, and postmortems of my own games — losses especially. Why a plan works, not what the engine says.

 EEG-BCI

Signals, without the hype

What brain rhythms actually are, how BCIs decode them, and a PhD done in public. Claims sized to evidence, always.

 METHOD

The machinery of studying

Tickets, dependency graphs, frozen contracts, spaced repetition — and honest reviews of the systems that didn't survive contact.
