  Phony Benoni: So, which Black pawn dies a hero's death? After a bit of looking, <27.Rfxf7> seems the way to go. That threatens the standard double rook mate on the 7th rank as well as 28.Qxg6+, and after <27...Rxf7 28.Qxg6+ Kh8 29.Rxf7> even a free check can't give Black a chance to cover both g7 and h7.
Jul-16-14  dfcx: white to move 27?

Candidates are Qxg6, Qxf8, Rcxf7 and Rfxf7. The queen sac does not produce any meaningful result, neither does Rcxf7. Rfxf7 threatens mate in two.

27. Rfxf7 Rxf7 (Qxd6? 28. Rg7+ Kh8 29 Rh7+ Kg8 30. Rcg7#)

28. Qxg6+ Kh8 29. Rxf7 Qg8 30. Qh6+ Qh7 31. Qxh7#

Jul-16-14  ASchultz: I considered 27 Rxc6? Bxc6 28 Qxc6 for a bit til I saw ...Rc8 29 Qf3 Qd4+.

It helped that this was a Wednesday puzzle, to make me look for more than just 2 pieces vs a rook, too.

Jul-16-14  estrick: <27.Rfxf7 Rxf7 28.Qxg6+ Kh8 29.Rxf7> allowing a free check was my line, too.

But 29. Qh5+! does not give Black the chance to strike back after 29...Kg8, 30.Qxf7+, etc.

White to play (27.?) "Medium/Easy"

Material is even, but White's queen is en prise. Despite this fact, White can ignore this and play a rook sham sacrifice which threatens mate.

27. Rfxf7! Rxf7

Or 27...Qxd6 28. Rg7+ Kh8 29. Rh7+ Kg8 30. Rcg7#.

28. Qxg6+ Kh8 29. Qh5+! Kg7 30. Rxf7+ Kg8 31. Qh7#.

  agb2002: The material is identical.

Black threatens 27... Qxd6.

The black bishop is defenseless but after 27.Qxd8 Nxd8 the knight protects it.

The pawn on f7 avoids 27.Qxg6+. This suggests 27.Rfxf7:

A) 27... Qxd6 28.Rg7+ Kh8 29.Rh7+ Kg8 30.Rcg7#.

B) 27... Rxf7 28.Qxg6+ Kh8 (else mate next) 29.Qh5+ and mate in two.

C) 27... Ne5 28.Rg7+ and mate in two.

D) 27... Ne7 28.Rcxe7 (28.Rfxe7 Rf1+ 29.Bxf1 Qxd6 30.Bc4+ seems to take much longer) wins.

  Once: Once you've got 27. Qxg6? out of your head, you've simply got to look at 27. Rfxf7. Rooks on the seventh threatening mate and Qxg6+ - what's not to like? Never mind that it offers the queen. She can join in the party when the pieces are back in the box.

Fritzie finds a defence I hadn't considered. After 27. Rfxf7 Ne7

For a brief second we have that horrible sinking feeling. Have we miscalculated? Does the knight jam up the rooks on the seventh and protect g6?

Nope, it's an illusion. The brutal warriors amongst us would play 28. Rcxe7 and continue as before. The philosopher aesthetes would choose 28. Qxg6+ and chuckle at the ironic repetition of the queen sac theme.

It's an interesting game to play through. Black seems determined to play with only his king's knight whilst white pushes pawns, grabs space and infiltrates with rook and queen.

There is an interesting moment after 24. Rd7 Ne5

Black's Ne5 leaves two pieces en prise, but white shouldn't take either of them. Fritzie says that 25. Rxb7 Qxc3 is pretty level, which seems a shame after white has had so much of the play. And of course 25. Qxe5 Qxd7 loses the exchange.

It turns out that white has only one move to preserve his advantage and get us closer to our POTD. 25. Rc7 protects the Nc3 and keeps a white hand around black's throat.

Cool play by Najdorf.

Jul-16-14  morfishine: <27.Rfxf7> Transfer of power is complete; White has two mating threats starting with 28.Qxg6+ or 28.Rg7+; Black cannot defend both g7 & g6

*****

Jul-16-14  Nick46: Reinhardt was by turns German, then Argentinian. Was the choice of this game motivated by Sunday's World Cup final, by any chance? LOL
Jul-16-14  Cheapo by the Dozen: None of 27 Qxd8, 27 Rxb7 or 27 Qxg6+ quite works. However, the fourth try does.

27 R(f)xf7 is obviously forcing -- it threatens mate in a couple of ways, threatens a bishop, steals a pawn, etc. 27 ... Qxd6 allows a straightforward mate-in-three via Rg7+/Rh7+/R(c)g7#. And so the main line becomes:

27 R(f)xf7 Rxf7
28 Qxg6+ Kh8
29 Rxf7

Mate follows quickly at g7 or h7, as soon as Black exhausts his spite checks.

Jul-16-14  lost in space: Easy one.

  gawain: Got the main point but I would have missed 29 Qh5+. I was prepared to play the less compelling 29 Rxf7.
Jul-16-14  SuperPatzer77: White to move and win - see diagram below:

27. Rfxf7! Ne7, 28. Qxg6+! Nxg6, 29. Rg7+ Kh8, 30. Rh7+ Kg8, 31. Rcg7# 1-0

  Penguincw: My neat jerk reaction was to exchange queens and then grab the bishop, but the knight can take of everything. I'm going with 27.Rxc6, but looking further, 27...Bxc6 28.Qxc6 Rc8 29.Qf3 Qd4+ will leave black down the exchange, so that doesn't work out.

Qg8 does cover both g7 and h7, it is just that 30. Qh5/Qh6 spoils that party.
Jul-16-14  Marmot PFL: Must be a record by black for pointless knight moves.
Jul-16-14  BOSTER: <gawain:Got the main point but I'd have missed 29.Qh5+>.
Looking for a gain of tempo, or playing with tempo is very useful strategy to know. One ex.

White to play.

Jul-16-14  e4 resigns: BOSTER - It looks like a mate for white.
1. Qf1 Ke8
2. Qb5 Kf8
3. Qxc5 Ke8
4. Qe7.

Also, good puzzle. I missed 29. Qh5! but 29. Rxf7 should win also.
