Every move in chess involves moving a piece to a square. Let us call this square the "move-square" for that turn.

In the following, the move-square of the black player must be symmetrical (over the obvious center-horizontal) to the move-square by white on that turn. The requirements may be met with a white move, but an additional valid move for black must be shown to exist. This extra move is not included when counting the number of moves taken to reach one of the below conditions.

What is the shortest sequence (with symmetrical move-squares) resulting in a Rook x Rook capture?

Resulting in a Knight x Rook capture?

  Hi @ArtemLugin, welcome to Puzzling SE! (Take the tour if you haven't already!) Can you clarify if the same piece has to occupy black's move-square as white's, or can any piece count? For example, would something like 1. e4 e5 2. Be2 Ne2 be acceptable? Or is only Be7 by black possible?

  @PiIsNot3 Its doesn't have to be the same piece. Only the corresponding symmetric square. Assuming you mean Ne7 not Ne2 yes, thats acceptable
