| Nov 12, 2020 at 10:23 | comment | added | Retudin | Yes (like pawns on the first row, the normal chess start does not matter) | |
| Nov 12, 2020 at 10:14 | comment | added | Neil | Are identical coloured bishops allowed even with 8 pawns on the board? | |

| Nov 11, 2020 at 15:24 | comment | added | Peter LeFanu Lumsdaine | @O.F.: The question is a max-min; it’s not asking for the longest walk the king can take (which as you say would be trivial, either “63” or “infinite”), but the longest walk the king may need to take to reach a given square. Given a position, we can ask e.g. “how many moves does the king need to reach a1?”, i.e. what is the shortest path for the king to reach the given square. The challenge is to find a position that maximises the answer to this question. | |
| Nov 11, 2020 at 13:39 | comment | added | Retudin | @O.F. The minimum moves needed(so no walking in circles), while the king may not be in a position where it's in check. (which means the king must maneuver around forbidden squares, and may need captures to free squares reachable by black pieces) | |
| Nov 11, 2020 at 11:01 | comment | added | user62273 | I may be getting the rules, or the entire question, wrong, but I figure, the longest walk for a lone king on a1 wishing to get to a8 is 55: a1 -> b1 ... -> h1 -> h2 -> g2 ... -> a2, so on so forth until b8 -> a8. Actually, if we allow walking back, or in circles, or whatever, we may claim the question, as stated, has infinite number of solutions! (a1 -> b1 -> a1 -> b1 -> a1, ad infitum). So, like I said, either I'm completely misunderstanding the question, or it is not a valid one. | |

| Nov 10, 2020 at 16:17 | comment | added | Retudin | Yes, that make most sense to me (too). | |
| Nov 10, 2020 at 16:16 | comment | added | Sleafar | So if I place a white pawn on e1, it can move only to e2? And in then next move to either e3 or e4? | |
| Nov 10, 2020 at 16:09 | comment | added | William Pennanti | Definitely got me thinking, upvote :) | |
| Nov 10, 2020 at 16:09 | comment | added | Retudin | Pawns on the first row are allowed, pawns on the 8th row not, if white ones reach it they must be promoted (such that the king reaches its destination fastest). I strongly doubt that will lead to a high number of moves though. | |
| Nov 10, 2020 at 16:05 | comment | added | Sleafar | Is it allowed to place white/black pawns on the 1st/8th rank and vice versa? What about promotion if all pieces are still on the board? | |

| Nov 10, 2020 at 15:59 | comment | added | Retudin | That is allowed, I'll adapt the text a bit | |
| Nov 10, 2020 at 15:56 | comment | added | William Pennanti | Also, can you start in check? | |
| Nov 10, 2020 at 15:54 | comment | added | Retudin | Yes black, and also blocking white pieces are allowed even on the target square; however the position must be reachable; I am not looking for the infinite answer. | |
| Nov 10, 2020 at 15:51 | comment | added | Retudin | I have no final answer, let alone a provable one. All moves are counted. (the title may be a bit misleading, but the description counts: white moves not white-king moves.) | |
| Nov 10, 2020 at 15:50 | comment | added | William Pennanti | Can the piece trying to be moved to have a black piece on it? | |
| Nov 10, 2020 at 15:47 | comment | added | Ben Barden | Do you have a final answer for this? Is a final answer provable for this? | |
