Try ROT13 on thmyl :
t→g, h→u, m→z, y→l, l→y → guzly (not obvious). thmyl-snab-tywb-andrwyd-42-2
Try (A↔Z, B↔Y, etc.) on first segment thmyl : Try ROT13 on thmyl : t→g, h→u, m→z,
That doesn’t immediately yield obvious English words. Try ROT13 on thmyl : t→g
t(20) ↔ g(7) h(8) ↔ s(19) m(13) ↔ n(14) y(25) ↔ b(2) l(12) ↔ o(15) → gsnbo (not clear).
