My first post...
@illyrialady - Oh, I see. This is very interesting and awesome.
I already knew that, Dave. Couldn't you tell? (I gave a hint of that a long time ago with my "You've really got to step up with this one" comment.
- Qa3!! Rc8!, 2. Qe7!! Rb8, 3. Bb3!!! (Holy Toledo!!!) Ra8, 4. Ba4! (again!!) Rb8, 5. Bb5 Rc8, 6. Bc6 Rb8, 7. Bb7! Ra8, 8. Qxg7+!!! Kxg7 (forced), 9. Bxa8 and White’s winning with two pawns!!! Holy Toledo!!!!
At illyrialady, 5... Ra8, 6. Ba6! Rb8, 7. Bb7! Ra8, 8. Qxg7!!!! Kxg7 (forced), 9. Bxa8 and White’s winning with two g and h pawns.
That's why, in the solution, the stepping stone dance between the White bishop and the Black rook is so necessary and charming.
I suppose the only other thing to point out about this puzzle is the care which
White must take to avoid Stalemate. For instance,
- Qa3 Rxg6+ (Bxg6??)
- Kf2 Rf6+
- Kg3 Rg6+
- Kf4 Rf6+
- Ke5 g6
- Kxf6 Kxh7 *
If at any point in the main line, the White bishop does not block the Black rook
from checking on the Black's 8th-rank, then the Black rook keeps checking, and
if White takes it, the result is Stalemate. For instance,
- Qa3 Rc8
- Qe7 Rb8
- Bb3 Rc8
- Bc4 Rb8
- Bb5 Ra8
- Bc6?? Ra1+
- Kf2 Rf1+
- Kg3 Rg1+
- Kf4 Rf1+
- Kg5 Rg1+
- Kh4 Rh1+
- Bxh1 Stalemate
- Ke5 Re1+
- Kd6 Rxe7
- Kxe7 Stalemate
Yep. Stepping stones. Black can defend against the back rank mate. The only way to win is, while black is defending against the back rank mate, at the right moment, take the pawn on g7 with the Queen. But it must be done when the Black rook is en prise. That suggested Qa3 followed by Qe7, and then the White-bishop-Black-rook two-step dance brought a big grin to my face. Very good and artistic puzzle. You got any more as good, Yancey?
Thanks, Yancey. It's a very interesting puzzle. At first I thought I wouldn't solve it.
Here is the solution. I'm looking forward to your next puzzle.
You've really got to step up to this one.
Got to get some food...will try to solve this in a little bit.
