It's still not obvious to me where to go from there to see your
announcement and the proof games you described.


>>> Knight with capture : not least [...]

By "shortest" I guess you mean "shorter" there.


>>> Rook without capture : 9 moves (Itamar Faybish)



>> This at least is not optimal:



>> 1 f3 h5 2 Kf2 h4 3 Qe1 h3 4 Kg3 Nf6 5 Qf2 Rg8 6 Kh4 Se4 7 g3 f5 8 Qg2 Rh8#



> Very nice game, and quickly realised !


Thanks, though again it seems that even this is longer than necessary.
