This puzzle is inspired by and has similar rules to the series of puzzles by Sleafar.
Definition. A copycat chess opening is a sequence of moves starting from the conventional starting position, where every move by White (including the last one) is copied by Black identically, resulting in a symmetrical position with respect to the mid-horizontal axis. Every move must be legal, but the last move doesn't have to be checkmate, hence the name opening instead of game.
What is the shortest copycat chess opening in which a rook captures another rook?
Answer
How about seven moves each
1) p-a4 p-a5 2) p-b4 p-b5 3) p(b)xp pxp 4) p-a6 p-a3 5) p-a7 p-a2 6) pxN=R pxN=R 7) RxR RxR
