Could someone explain this one to me? It's called Pseudo-Kiss Complet in another database. Letter explanations OK, but I would really like something verbal. I also found some moremovers using this two move theme, does anyone think that is a good thing intentionally or was it just an artifact the program picked up?

As you probably know, Kiss cycle is a new-strategical theme the best characterized by scheme
1.A 1...a, b 2.B#, C#
1.B 1...a, b 2.C#, A#
Complete Kiss theme then adds the third phase
1.C 1...a, b 2.A#, B#
While Kiss cycle is just difficult to show, complete Kiss theme is devilishly difficult to show. As far as I know, no orthodox twomover managed to do that.
Then, if we move to the area of pseudo- themes, this is entirely different matter. Pseudo- themes in this area are characterized by the fact that defences might be (or should be, depending on the interpretation) different. Complete pseudo-Kiss cycle is then:
1.A 1...a, b 2.B#, C#
1.B 1...c, d 2.C#, A#
1.C 1...e, f 2.A#, B#
Actually, it is very easy to show e.g. in the variations of the orthodox threemover (ocassionally called Visserman approach to new-strategical themes) by using known Jacobs mechanism of three black pieces guarding pairs of three possible mates and simple withdrawals. E.g.
Jean-Marc Loustau
3rd Prize USPB 1984
 (= 9+11 )
#3
1.h7! th. 2.h8B/Q
1...Sxh7 2.Bb2+ Rd4, Rc3 3.Rxc5#, Qe2#
1...Ra7 2.Rxc5+ Sd5, Rd5 3.Qe2#, Bb2#
1...Rh1 2.Qe2+ Re3, Se4 3.Bb2#, Rxc5#
So, I think that the pattern theme in threemovers (and some fourmovers) is actually consequence of the strategy. But the pattern itself is very easy to show in the given mechanism.

Thanks. Does Pseudo then mean that one of the cycles might not be fulfilled, just most of them?
I ask because as I filled in the table (a to A, etc), everything corresponded but one of the cycles.

Complete means all white moves appear at all phases. Without "complete" two phases are enough.
Pseudo- means that defences might be (or should be) different, not the same in all phases.

Juraj you are an excellent educational resource. Thank you so much for being so helpful to the problem community.
