Hi Mike!

I tried to analyze (with engine assistance) and white can force its way for a
K+N invasion into black camp even if blacks king would position itself first at Ka5 or Ka6 before the b3 push. So I guess, the win is forced.

Please show!
Having your line would make it easier to others with weak hardware (such as me at the moment still).

I noticed f8 square needs to be defended by King because of Bf8 forcing g6 and Bh5 will be trapped. Not easy to position black K to defend queens side because of f8 weakness.

Nevermind Mike, problem to me rather is, that your .pgn is only 33 moves long. and you deviate right from the start from author's solution (if it really is his one, I talk about the one given at YACPDB), so the taking of the white Rook happens at a time, when White's h-pawn is still on the board, which changes a lot, as you wrote somewhere by yourself. Could well be, that Black should just wait with this till White has given the h-pawn, which he probably would have to sooner or later yet.

The deviation of yours is 1...Kd8 instead of ...Kf7, so just theoretically even if your line worked, it doesn't mean it would do so for the other one first black move too., just to be sophisticated.


And even at this one your line, I don't see any progress after just 32...Kc6 instead of ...Be8 (?) there.
BTW, after that 33.Ne6 instead of your last move 33.Be8 (?!) get's #37- output of MF already.

Taking back the last 3 plies with full hash and playing 32...Kc6 instead of your ...Be8 (?) lets evals drop, output looks like that:

Please don't follow this output- line ply by ply too far as for proving anything, at the end eval isn't much better then at start, yet there will be some blunder- moves for any side maybe, didn't have a closer look by myself.

But just be so kind and give a line of your own with some eval- progress to be seen, if you manage to get some after 32...Kc6, the position of the dia.

To me Black's King seems to be able to hold opposition against white one again, doesn't it?

My hope went off after author's solution up to move nr. 49, where Marek found 49. Ke1 (?) going wrong.

Will try to analyze this position, but this looks like we'll end up with Rc2 bxc2 line that reverts back to the b3 move. Where a N+B or K+N attack on pawns
would win. Will try and post shorty.

Maybe you are correct about the impossible win without h4 pawn.
Position is a bit difficult and might take some time or maybe there is really none.
The B of black is defending important squares for the N so a N+B attack on pawns looks impossible on my analysis. A cook after bxc2 without h4 pawn? Will let my machine calculate overnight and see tomorrow if eval improves.

I made a data update for the EPD records, where all positions are now analyzed to 70 plies or more (for positions where there is a checkmate, my database only updates if a shorter mate is found, so those may have lower depths recorded, but the positions have been analyzed to at least 70 ply).

I analyzed these to greater depth:
