Calculation is visualization under a different name. When you try to see three moves ahead and the position goes blurry on the second one, the limit is not your chess knowledge — it is that you cannot hold the board steady in your head. That is trainable, and it is trained by rebuilding positions, not by staring at them.
This drill shows you a real position from a known opening, takes it away, and asks you to put every piece back on its square. Recall is deliberately harder than recognition: you have to reconstruct the position rather than tick off pieces you are shown. Difficulty scales with how few pieces you are given and how long you had to study them.
Because the positions come from openings rather than random piece placements, what you are memorizing is structure — pawn chains, typical squares, the shape a line produces. That transfers to your games in a way that memorizing arbitrary arrangements does not. It is the cheapest available route toward blindfold play, without starting at blindfold difficulty.
Yes, and more reliably than most chess skills, because the feedback is immediate and unambiguous: either the piece was on that square or it was not. Progress tends to show up within a few weeks of short sessions.
It is the first half of it. Blindfold play requires holding a position and updating it as moves are played. This drill trains holding it accurately, which is the part that fails first for most players.
Random placements train raw recall; opening positions train chess memory. Strong players remember positions in chunks — a pawn structure, a castled king, a familiar bishop pair — and only real positions have those chunks to find.
A few positions a day beats a long session once a week. Visualization fades quickly without use and rebuilds quickly with it.
