I love subtle twinning, and this is more subtle than most: not a change from one fairy condition to another, but a change between two forms of the same fairy condition! So the changed play (Lacný) is caused solely by the right for a piece to capture on its own rebirth square: legal or not?

The mechanism depends on the fact that b1-c1-d1-e1 are rebirth squares both for white attackers and for black defenders (because they are all fairy pieces). So part b (Cheylan) is fairly automatic: Black leaves a thematic square, so White is able to go there (no capture) but Black is unable to defend by going back (with capture). Part a (Calvet), however, has required constructional tricks: the defences must let in other thematic mates according to the Lacný pattern. This has succeeded very well.

A valuable extra feature is the fact that the two parts have different keys. Naturally, this differentiation is also caused by the difference between Calvet and Cheylan.

(If you read between the lines, you can see that I too find the problem excellent!)

Nice
a) better than b) but it does not really matter here .
Can be shown in a less conventional way:
2# anticirce
the solution being split in two
– if you mean “Cheylan”
– if you mean “Calvet”
