Nov 14, 2020 at 8:33 comment added Retudin I am convinced your number is wrong: The moved horse adds 2 to the cycle length, so your total is higher than 139. It can be increased by one with a pawn on h8. Please recalculate, claim this as your own adaption and don't ask my help. (This pollutes chat, if I see something I will volunteer it)

Nov 13, 2020 at 15:03 comment added Retudin the pawn covers b7, so must be taken. and OK
Nov 13, 2020 at 14:50 comment added Rewan Demontay What god does adding a pawn on a8 do? The White king never goes there. But I have some ideas with Black pawns. You'll see soon enough. :)
Nov 13, 2020 at 14:35 comment added Retudin Well,I just upped my solution to 74; only 56 to go :-).Oh wait, success: 131 (your solution, with an extra pawn on a8, just to prove there are better 'illegal' ones)
Nov 13, 2020 at 12:21 comment added Rewan Demontay @Retudin My answer has now been amended with a 129 move long record.

Nov 13, 2020 at 12:02 comment added Rewan Demontay @Retudin Without promoted material is easily mended-will update soon.
Nov 13, 2020 at 6:58 comment added Retudin This is crazy, definitely something fascinating. It had not occurred to me at all that checking the black king must be prevented; I do agree with that. I do feel however this violates the 3rd requirement: pawns promoted to rook are not starting material.
