Time for the knights. We'll start with three miniatures and a nice co-production.

The last two compositions show more than one colour change. This is even more fascinating and it's only the beginning.

The white knight seems to be well placed on c5, especially after one has seen the solution to a). But Black has no waiting move (1. Na5 Rd..h5 2. ? Rd..h8#).

Black or White (3)

Bishops changing colours are next — surprise, surprise. No. 1 with the "same" moves in both phases is my favourite in this installment. Of course, all those ideal mates shown in the other three chess problems are also very beautiful.

We'll continue with the rooks. No surprise, right?

Black or White (1)

Do you know or remember the twinning according to Forsberg? I wrote about it here. How about variegating this theme? We would not change the piece type but change the piece colour.

When I started collecting appropriate chess problems for this subject I had no idea that there are so many nice compositions, though I already restricted my search to helpmates in two moves! Therefore, I have decided to split up my findings into different sections. The first part is about queens. Here we go ...

On the traces of Giegold (2)

Let's have another look into my own history book. Here some more of my compositions. Enjoy!

No. 1 has the try 1. Be4? h6? 2. Bb1 hxg5 3. Rc2 Ke4 4. Rc4# that is naturally refuted by 1. - dxe4! The solution goes 1. Be2! h6 2. Ba6 hxg5 3. Bb7 Ke4 4. Rc4#. Too bad that there is no way to convert the try into another variation. No. 2 is a nice puzzle, I think. 1. Ka4! Kd4 2. Rc1 Ke3 3. Rd1 Kd4 4. Nc4 Kxc5 5. d4#

The third chess problem shows two white pieces "going home": 1. Bh3! h5 2. Bf1 h6 3. Ng1 Kd4 4. Nf3+ Kc5 5. d4#. The last diagram is a bit of a mystery. When I saw it some time ago here, I immediately knew that it was composed by me. For example, I remembered how I tried to do better with those white pawns on h5 and h6. The really strange thing is that I have no other memory or any notes about when and where it was published for the first time. I only know it was reprinted in a newspaper in 2004 (Stadtzeitung Rieselfeld 12/2004 Nr.34). The comment for that diagram states it was published in a German TV magazine somewhere in the 1990s. But I am sure that also was a reprint. Can you help me with that issue? The solution is 1. Ra4! (threat 2. Bd4+ Kxd4 3. Qc3#); 1. - c5 2. Bb8+ Kxf6 3. Ra6# or 2. - Kd4 3. Qc3#; 1. - f3 2. Qxe3+ Kxf6 3. Bd4,Qd4,Qe7#.
