King Maze Puzzle

Can you get the white king home to e1 in this position using nothing but king moves for both sides. Not as easy as it seems!

The black king must do his best to stop white from getting home (including things like trying to mate or stalemate himself so that there are no more available king moves).

Good luck!

All moves are forced except one, which is just easier to win.

This should get us to triple digits, unless cooked.

Goal: get white K to e1

Both sides can only move their King, though the other pieces still threaten squares normally.

PS: yes, it's illegal; I know. I'm tired. :P

@BidDoggProblem Wow yeah, that's beautiful (100 moves exactly!) and looks like it has potential to be even longer (don't worry about illegal positions and feel free to change the target square)!I came up with this one which I think is mabye longer but I could have missed something.

I whittled it down to this, but I can't seem to capture any more pieces, except for Bd8, of course.

Yeah, the route's a tricky one to find but try leaving the rook on f3 until later, that way the g2 bishop won't control a8 so the black king won't be stalemated.

You can probably do it in less, but this is what I got.

@y2721: 91. Kxa5+ Kc8 92. Ka4 Kd8 93. Kb3 Ke7 94. Kc2 Kf6 95. Kd1 Kxg6 96. Ke2 Kh6 97. Kxf3 Kh5 is a problem.

Meanwhile, here's my take on it.

King maze. Get the white king to h1. If it's not cooked, I count 40 moves, with too many duals to count near the end, so I can't really tell what the best black defense is. (First bunch of moves should be unique though.)

[COOKED - see posts below for fix (?)]

Sorry, the rook and pawn on the g-file should have been swapped around on my last puzzle. Remellion, how do you get to h1 even without black pieces on the board? Looks interesting though!

That is the whole point of my problem. Removing black pieces is easy; the white king just captures them. But now white has to find some way to remove a white piece from the board.

Ah ok, really cool idea! This is far as I can get and can't see a way to avoid this . However even if I could force the black king to g1 when the white king was on h4 couldn't black always just move to f2?

(1) There is a way to avoid it - but you have to be aware of the idea from the start.
(2) Once the king is on g1, there is a way to force it out from the f2-g1 corner.

As for your problem: I can find 127 moves, after the first 90 by y2721.

Ok thanks. I'll only post again once I've got it. It may take some time as it's a very good puzzle!

First 28 moves are unique and correct - that was the intention, well done!

Unfortunately I made a mistake; there isn't a way to get the black king out. Sorry!

As for fixing this: Maybe a white bishop on b2 instead of a pawn. Then the black king can't use c1. I think that should work.

Wow, beautiful puzzle! Yeah, that seems to work, thanks for creating it!

I recently reviseted the problem of king mazes and have come up with this. It's quite a long one. It uses ideas from all the previous mazes and should be fun (and difficult) to solve. You can only use king moves for both sides and black must try their best to stop white from getting to the target square (including trying to stealmate or checkmate himself). How many moves does it take you to get the white king to a1.
