The cluster of tries: Kh2-g1-f1-e1-d2-...-e8 0-0-0 Td7 is 12 moves: just too long.
In the diagram, e.p. is not permitted because last move might be g3-g4. So first shift sK to h4. Following the e.p., check that wK does now have prior move: Kf4-f3. Now sK scampers to e8 where through consequent forgetfulness it recovers castling rights.

A.Buchanan: Without sTa5, Black castling rights would be gone. But I don’t think that observation is sufficient to make the problem retro, even if sTa5 had no role in the forward play. Have changed the genre from

Perikritische Umgehung der Schnittpunkte e5 und f6 - hin und zurück. Akkurates PendelManöver eines wL damit wS und wT ihre Lestimmungsfelder erreichen können.
