Black or White (4)

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.

Solutions
1a) 1. Nd6 a3 2. Nb5 Nb6#
b) 1. Kb5 a4+ 2. Ka6 Nc5#
2a) 1. - b8=N 2. Kxe8 Re6#
b) 1. - Rd6 2. Rc8 bxc8=N#
3a) 1. Na5 Rc4 2. Nb7 Rc8#
b) 1. Nb8 Na6 2. Rb7 Nc7#
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#).
4a) 1. Rf3 Rd5+ 2. Rf5 Nf3#
b) 1. Rf4 Rc5+ 2. Rf5 f4#
5a) 1. Nc6 d6 2. Na7 Bc7#
b) 1. Ra7 Bc7+ 2. Ka8 Nb6#
c) 1. Be6 Bb6 2. Bf7 Nxd7#
6a) 1. Nf3 gxf3 2. Nh5 Rg4#
b) 1. Nf3 Nf5+ 2. Kh5 g4#
c) 1. Rh2 Nh3 2. Kg3 Nf5#
