Copycat chess is back












9












$begingroup$


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?

    Does it need to be symmetrical up to the rook capture or after the rook capture?

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

    I hope this answer doesn't get sniped...




    It did get sniped, but @penguino had an answer that I built off of:


    1. a4 a5 2. b4 b5 3. bxa5 bxa4 4. a6 a3 5. a7 a2 6. axb8=R axb1=R 7. Rbxa8 Rxa1




    Explanation:




    We can't have one of white's rooks that's already on the board take one of black's rooks across a file, since that move would not be copyable. Also, it's impossible for the rooks to capture each other along a rank, since that would require the rooks pass each other at some point, which cannot happen as they will mutually block each other each move they make.


    The only other way to have a rook takes rook opening would be pawn promotion, whereby the mirrored pawns promote to a rook and then take the already-there rooks. This quickly leads us to the pawns on the a- and b-files (or g- and h-files), and thus, the solution above.

      Regarding your explanation, it's a tiny bit trickier: why couldn't the capture occur horizontally and hence be possible to copy? (with the 4 rooks involved...)

    • $begingroup$
      @ArnaudMortier: for a horizontal rook capture a rook would have to move to the opposite side of the board. This can't be mirrored because the rooks would collide. ie assume no other pieces in the way to move a rook from a1 to a6 is possible but then the opponents rook would need to move from a8 to a3 - impossible due to the rook on a6.

    Here’s another way, but on the kingside.




    1. g4 g5 2. h4 h5 3. gxh5 gxh4 4. h6 h3 5. h7 h2 6. hxg8=R hxg1=R 7. Rhxg1 Rxg8




    And while I’m at it, here are the fastest way to do this with all other pieces, minus the kings of course.



    Pawns:




    1. a4 a5 2. b4 b5 3. bxa5 bxa4




    Bishops:




    1. b3 b6 2. Bb2 Bb7 3. g3 g6 4. Bg2 Bg7 5. Bxg7 Bxg2




    Knights:




    1. Nf3 Nf6 2. Ne5 Ne4 3. Nc6 Nc3 4. Nxb8 Nxb1




    Queens:




    1. b4 b5 2. c4 c5 3. cxb5 cxb4 4. b6 b3 5. b7 b2 6. bxc8=Q bxc1=Q 7. Qdxc1 Qxc8




    Now I can say that I have predicted the future! ;¥ ;D

      It wasn't my intention to make the same puzzle with other pieces. For me the rooks are by far the most interesting because you have to find the trick, otherwise it's not possible (fastest or not).

              Regarding your explanation, it's a tiny bit trickier: why couldn't the capture occur horizontally and hence be possible to copy? (with the 4 rooks involved...)

              @ArnaudMortier: for a horizontal rook capture a rook would have to move to the opposite side of the board. This can't be mirrored because the rooks would collide. ie assume no other pieces in the way to move a rook from a1 to a6 is possible but then the opponents rook would need to move from a8 to a3 - impossible due to the rook on a6.

            Here’s another way, but on the kingside.




            1. g4 g5 2. h4 h5 3. gxh5 gxh4 4. h6 h3 5. h7 h2 6. hxg8=R hxg1=R 7. Rhxg1 Rxg8




            And while I’m at it, here are the fastest way to do this with all other pieces, minus the kings of course.



            Pawns:




            1. a4 a5 2. b4 b5 3. bxa5 bxa4




            Bishops:




            1. b3 b6 2. Bb2 Bb7 3. g3 g6 4. Bg2 Bg7 5. Bxg7 Bxg2




            Knights:




            1. Nf3 Nf6 2. Ne5 Ne4 3. Nc6 Nc3 4. Nxb8 Nxb1




            Queens:




            1. b4 b5 2. c4 c5 3. cxb5 cxb4 4. b6 b3 5. b7 b2 6. bxc8=Q bxc1=Q 7. Qdxc1 Qxc8




            Now I can say that I have predicted the future! ;¥ ;D
