So Much to See!

This is one of those positions where you just know there's got to be something on, even if Fred hasn't already told us so. If only we could get a pointy bit on the a1-h8 diagonal there's mate with Nh6, but attempting to get Black to leave the d- or e-files by say Re1, Rb2, or Rc2 meets stiff resistance. The solution turns out to be a wild ride through a lot of little combinations. The variation tree is straight, but quite long with a few side points.

Reinfeld position #563
White to move

First, White penetrates to the back rank to make a variety of pins and Rook forks using a clearance sacrifice followed by a decoy.

1. Rxb5 cxb5 2. Rc8 Qd5 if the Rook is captured, White gets his way with either Qa1+ or Qd4+.

Reinfeld position #563
After 2. ... Qd5

Now Black threatens Qh5#. 3. Qa1+ another decoy as now 3. ... Rxa1 4. Rxf8 Kg7 5. Bh6#. 3. ... e5 4. Bxe5+ now if 4. ... Rxe5 5. Rxa8 Black looks like a pin-cushion.

Reinfeld position #563
After 5. Rxa8 (variation)

4. ... Qxe5 5. Rxf8 Kg7 6. Rf7+ this Rook has done an amazing amount of work behind enemy lines without direct protection. It's reward is to go out in a blaze of glory by decoying itself again, in order to buy the Queen a tempo to win a Black Rook.

Reinfeld position #563
After 6. Rf7+

6. ... Kxf7 7. Nxe5+ Rxe5 the Queen is forking the two Rooks and will capture one next move.

And it all looked like it would be so easy when I first saw this problem...
