Henrik Juel: White king corrects the tempo by passing e8, the only square where he is safe from Lg2
He does a long march, but not a round trip (2023-08-15)
SCHRECKE: 10. ... a3 11. Kc3,Kc5 (Dual) (2023-08-15)
msterkowiec: Maybe it will be interesting (for me it is) that this position can be easily transformed into #34. This is because pawns wh.a5 and bl.a6 are only to avoid later/minor dual (there would be also 9.Ka5 without these pawns).
If remove these pawns (and accept minor later duals) and add black pawn a7 (8/3p3p/3P4/8/p4N2/rpK1p1pp/1p2Bkbr/bR5n) we would have the following #34: 1. Kd4 Ra2 2. Ke5 Ra3 3. Kf6 Ra2 4. Ke7 Ra3 5.
