Black or White (5)

Finally, no surprise, there are the pawns that change colours. As I've found so many examples, I selected the miniatures that have no captures and end with ideal mates.

I already indicated in the previous post that there is much more you can do with this colour change effect — you'll see in the following weeks.

Solutions
1a) 1. Kc5 Bh4 2. b6 Be7#
b) 1. Ka5 Kc3 2. b5 Bc7#
2a) 1. Ne3 Ng6 2. Nd5 Ne5#
b) 1. Na1 Rd2 2. Nb3 Rc2#
3a) 1. Nd4 Bd1 2. Nb3 Be2#
b) 1. Nf4 Re1 2. Nd3 Re4#
Observe the move patterns: N-B-N-B and N-R-N-R. Maybe just a coincidence, still nice.
4a) 1. Bf6 Rh4 2. Re5 Nd4#
b) 1. Re6 Rg4 2. Be5 Ne3#
