One sharp sentence you read vs five paragraphs you skim
Long auto-generated essays on every ply of a forty-move game quickly cause analysis fatigue: when everything gets six bullet points, the one moment the game actually turned gets buried. Brass Pawn’s coaching layer does two things before speaking: first, it converts engine evaluations to win probability so harmless centipawn jitter is ignored; second, it states the concrete board feature that changed — “takes the open d-file”, “plants the knight on the e5 outpost”, “breaks up the enemy bishop pair”.
Because that logic executes locally on top of Stockfish 18 or Reckless 0.10, it runs instantaneously during live practice games at zero per-game cost.
Active judgement beats passive reading
Reading why an engine liked a move feels productive even when nothing sticks. Brass Pawn pairs move coaching with active recall: 116 quiet Positional judgement exercises force you to commit to an evaluation (“slightly better”, “balanced”) and a move before seeing the feature breakdown.
