Glitch in 4 vs 3 - RP Passive Rook on Practical Rook Endings in the practice section

No matter what move you make it gives a fail instantly

can confirm, 100% completion practice speedrun is no longer possible

It's true for most of the moves, but try Ra2 - it doesn't fail you.

I tried for some minutes and I can reach something like 13 moves left and then each possible move is considered wrong by the engine. Is there a statement about this position? Is it theoretically a draw?

My method was to give checks on the a-file over and over, and when the king gets too close, give checks on the 1st rank - you can try it, if you want.

I gave a look and manage to 'win' on the first try.
There is no Glitch its draw

Care to give the moves? I can’t beat it, none the less study it

Thank you for reporting the issue. It probably sometimes happens because of low depth evaluation. I slightly changed the position, I hope it works correctly now.
