Rooks ending puzzle

White to play! Enjoy.

I suggest you try to solve this, it's very nice :)

Hmm, I don't see any forcing moves to win, and white has a lot of replies to anything that's not a check. Obviously white's b pawn can't move, and I think the king and b rook look fairly well placed to stop black's promotion.

I'd probably play d7 but no idea what black would reply with.

1.d7 Rxb2+

2. Rxb2 cxb2 3. d8=Q+

If Rb8, Qxd2.

If Ka7, Rxb7+

1.d7 Rxb2+ 2.Rxb2 b3+

Am I on the right line?

3. Rxb3 Rxb3 4. d8=Q+ Rb8 5. Qxb8+ Kxb8 6. Rd3

No, black cannot allow white to promote, ever.

I'll play some more straightforward moves.

Tricky. Well, Kxc2 or Kc1 draw by stalemate.

I'd try Ke1 and block the check with the rook. Then I think black's losing as the king is stuck on the a file, queen has no checks and you're threatening Ra1 and winning the queen.

Exactly :)

Nice! Thanks for that.
