What opposition? It's your standard mate with Rook and King.

i don't think it is standard ... black needs the white king on rank with his king, and with the move. white can avoid this. please post the line you see that wins in 4.

The white king is stuck on the a file.

The black king can just move down the c file to c2, and then deliver mate via Ra6.

Any pawn moves don't help as they are too slow...

no worries.. black might still win from there, but i reckon would take a bloody long time.. better to go pawn-hunting with his rook. 🙂

I would say black because he has the check in hand and may get the mate in before white can queen. There still is that problem of forcing the king to a mating position however, when the opposite side has pawns to move. When you look at the rook check, the king goes to b2 and that stops any incursion of the rook at least till the black king can back things up. Sticky wickett.
Setting the pieces up, I don't see how black stops the pawns.

Letting Fritz loose on it, it gives white a +11 to +12, it is in full analysis mode, taking hours and has only made a few moves and has backed up to square one several times, mostly starting with ...K-a6.

Quick, someone recommend the original board with 7 pawns!

No way. It is very easy to win with 3 pawns against a rook, I've done it in real life. In such arrangement Black has no chances unless White just starts doing stupid things like not moving the pawns at all🙂
