Company currently uses IPv6! For awhile firewall rules kept biting us as we’d realize something worked in ipv4 but not IPv6 but now I forget it’s even a thing really.
I once paid for a vpc host that was exclusively IPv6 and was shocked how many things broke. I was using it for a discord bot and the discord api didn’t even properly support IPv6 …
So, I’m an amateur… but this was confusing to me. I setup the board as you instructed and tried to play it out. You’re right. The way you described it is impossible…
So! I grabbed a pdf of the book you’re talking about and you missed the first two steps of the solution.
Solution is as follows: (White trading rooks is a winning position with the pawn so far up field)
Next is where your part of the solution comes in… where it discusses that white should move the king farther up the board instead of the tempting Ke6 position. (Because Ke6 would allow the Black king to take the pawn and open the door for the black pawn to become a queen or a draw)
