A very interesting note worth reading again from time to time.

What makes me wonder here are the remarks about old shatranj and that
K+4F (same colour) should win against K+R. I tried this by hand and found no way of confirming this claim. 5 Ferzes of the same colour are a different thing: A chain of Ferzes along the long diagonal can confine the rook in one diagonal half of the board (with the help of the King and noting that it is forbidden to give permanent check in Shatranj). Then, the net of Ferzes can be tightened until the rook is caught in a net and can be taken by the King.

There is still considerable counterplay by an active defending King, and exact play is needed.

I think, the mentioned scenarioes are worth a computer analysis.
