MatPlus.Net Forum Moremovers The "mirror moves" theme

### The "mirror moves" theme

The theme that I call "mirror moves" was apparently used in the 3rd WCCT. White and Black make the same moves, but mirrored, inducing a weakness in the black position that is not there in the beginning, that can - preferrably in a logical way - used by White.

I give only the relevant main line in the following examples, taken from Wieland Bruch's new book "Dieter Kutzborski: Verschlüsselte Steine".
I would like to see more examples of this theme, so please post them (and also a link to the 3rd WCCT brochure, if it is online).
I know some crude examples of this theme in studies as well (the "double helix" study that I think I quoted in an EG article about "WCCT X"), but also examples from other genres such as studies, selfmates, etc. are welcome. I post it under "moremovers" because the problems I saw both are moremovers.

There also is a famous game by Capablanca vs. an unknown player, where the unknown player mirrored (almost) all moves - until Capablanca gave a check and mated in three more moves. It went like this (but possibly the move order was different):
1.e4 e5 2.Sf3 Sc6 3. Sc3 Sf6 4.Bb5 Bb4 5.d3 d6 6.0-0 0-0 7.Bg5 Bg4 8.Sd5 Sd4 9.S:b4 S:b5 10.Sd5 Sd4 11.B:f6 B:f3 12.Qd2 Qd7 13.Se7+ Kh8 14.B:g7+ K:g7 15.Qg5+ Kh8 16.Qf6 mate

Examples:

1.Se7!? Se3! 2.Bh6 B:h4 3.B:e3 B:e7!
1.Bd6? Bd4! 2.Se7 Se3 3.? (waiting move)

1.Bh6! B:h4 2.Bf8 Bf2 3.Bd6 Bd4 4.Se7 Se3 5.h4!, and zugzwang: 5.-B~/S~ 6.B:c4/S:d5 mate

Siegfried, where is bK in the second example?

It fled the scene because it didn't want to be checkmated.
I put it back in, thank you!
Gotta keep an eye on those pieces.

The 3rd WCCT theme:

In a thematic try, black repeats the manoeuvre or idea of white, thus defending the try. In the solution, the same manoeuvres are played by white and black, but white is able to force the mate.

Obviously this comes to mind first:

Of course, it's not mirrored, but rather "same direction".
But it can't be mentioned often enough anyway :-)

Give me ten minutes and I compose a 2# with mirror moves :-)))

EDIT: Also, my SCHWALBE problem is somewhat relevant: How can White hinder
Black to mirror his moves (from game start position)?
No points until you find 7-8 possibilities!

Just to share it, here is what I belive to be the “double helix” study that was mentioned.

Yes, this is the study known as "double helix".
