I'll repeat then.

The engine doesn't have to "understand" because it is playing in a GUI that
"understands" for it. It understands the first repetition and the GUI handles it
from there, perfectly legal by design.

Maybe he was using the adaptor because he knew that under winboard his engine
wasn't fully functional, so he used a solution that would patch his wholes.

Nothing wrong with that since the UCI is also a recognized solution.
Whether he is using a WB engine with adaptor under the Fritz GUI or playing with
the engine directly in WB isn't important, as long as the solution works.

Shredders solution did not work, Jonny's did work, very big difference here.

(is this consistent enough for you?)
