Anirudh: This can be fixed by moving the Bishop to c8
Solution: 1. Ba6 h5 2. Be2 hxg4 3. Bf3+ gxf3= (2022-11-05)
Arnold Beine: A fix that does not keep the main contents is not helpful. Here the two tempo moves with switchback got lost. The propblem could be fixed by +wPd2, +bPd3, bPh6 to h7 without changing solution and contents, but the construction is much worse and that is also not very helpful. (2022-11-05)
A.Buchanan: Please keep the tone civil. I think the very quick fix is helpful, as it shows what can be achieved with the current material and stipulation. If I wanted a switchback problem, I might be tempted to change the stip from hs=, or use a rook instead of bishop, etc. Or find some other opportunistic feature apart from switchback. Maybe dual bishop promotion with shielding of bKh1 from wBa8? (2022-11-05)
