| percyblakeney: Monokroussos showed something a bit similar in his blog from a game played a couple of weeks ago. Black resigned before the combination was played out, otherwise the finish would have looked like this:

| Funicular: I've alwayls liked Qg3 better. This is a beautiful "quiet" move, but Qg3 is more visually stunning, since it's in front of the kingside castling. It's like "Nowhere to run" This is just as Petrosian - Pachman Bg7 i think it was |

| kevin86: The move in itself is not the greatest in my opinion,but the follow-up is! 31  c7!!  xc7 32 b7+!! xb7 33  xc5#
WOW!!! |

| brainzugzwang: OK, here's the patzer question of the day: What's the followup to 30...Kxa5 that I'm not seeing? I see a whole bunch of danger for the black K, but I'm not seeing what nails it down. |

| dhotts: <kevin86 31 Bc7!! Qxc7 32 Qb7+!! Qxb7 33 Rxc5#> I don't think this is mate as 33...Rxc5 and now what does White do? There must be something wrong with the move sequence as Black has a rook at c8 that can recapture on c5. |
|
| Jun-26-09 |
| dhotts: <kevin86> Actually there is nothing wrong with the move sequence, the mate occurs as follows. 31.Bc7 Qxc7 32.Rxc5+ Qxc5 33.Qb7+ Kxa5 34.Ra1#. |
|

| jsheedy: <brainzugzwang> If 30. Kxa5, 31. Ra2+ (or Ra1+), Qa4, 32. Rxa4#.

| WhiteRook48: this pun is weird |

"Ashes to ashes" ...
Part of the Christian burial service (ashes to ashes, dust to dust). A song by David Bowie.
A british martial arts film.
A british TV series about a time travelling policeman (series one) and policewoman (series two and three). A star trek voyager episode.
A Faith no more song.
Quite a clever pun, at least that's what I thought. |

| Once: Okay, let's see if we can map all the main variations here. From the starting position ...
click for larger view... white threatens both 32. Rxc5# and 32. Qb6+ Kxa5 33. Ra2# or Ra1#. Any "pass" move by black gives white a choice of these mates, so black needs to block the attack, give a perpetual check or a move that defends both b7 and c5. Let's try the rook recapture first:
31... Rxc7 32. Qb7+ Kxa5 (32...Rxb7 33. Rxc5#) 33. Ra1+ Qa4 34. Rxa4# Then we'll try the queen recapture:
31... Qxc7 32. Rxc5+ Qxc5 33. Qb7+ Kxa5 (33... Qb6 34. Qxb6#) 34.
Ra1#
Then let's try to interpose the black queen:
31... Qc6 32. Rxc5+ Qxc5 33. Qb7+ Qb6
34. Qxb6#
Then we can try a pawn block:
31...c4 32. Qb7+ Kxc5 33. Rxc4#
Throwing a rook doesn't help either:
31...Rxg2+ 32. Qxg2 Now the finish will be as for the previous variations. For example, 32...Qxc7 33. Rxc5+ Qxc5 34. Qb7+ Qb6 35. Qxb6# Can't claim too much credit for spotting all this - Fritzie did the hard work. A fabulous achievement for Tarrasch to work out the complications OTB. |

| lzromeu: <once> Tks a lot. Really beautiful puzzle-move. |

| sleepyirv: <Once> Thanks! I really like this game and thought it was really worthy GOTD. Spent a good 10 minutes trying to find a pun out of Plachutta until I came up with this entry. |

| ROADDOG: <once> Thanks for showing the lines after 31.Bc7. Amazing. Could or did Fritz find Bc7 after 30...Kb5? |
|
| Jun-27-09 |
| Lightboxes: IF 30. ... Kxa5
Then
31. Rxc5+, Rxc5
32. Rxc5+, Kb6
33. Rc7, Qe6
34. Qb7+, Ka5
35. Rc5# |

| Once: <ROADDOG: Could or did Fritz find Bc7 after 30...Kb5?> Afraid so! Bc7 is one of those counter-intuitive moves that we mortals find so difficult, but the computer spots in an instant. I've got Fritz11 running on a so-so laptop and it found Bc7 in about 2 seconds. I suppose the computer's weakness and strength is that it has no intuition or feeling about a position. This means that it will examine a lot of garbage moves that we would dismiss in a heartbeat. But occasionally one of those garbage moves will turn out to be pure gold. That is why the computer is a lot better than us at finding counter-intuitive moves, such as putting a piece en prise. |

| gilbav: <whiteshark> I think the combination in Navara - Dergatschova Daus is not a Plachutta. It seems a little simpler. The rook and bishop are not similarly-moving pieces -- if one of them takes on c6 it blocks the other, and that's it. See http://en.wikipedia.org/wiki/Plachu... |
|

 |
| acirce: That Navara combination is a Nowotny. Also rare in practical games but most likely quite a bit more usual than the Plachutta. |

| kevin86: OOPS,I guess I got may syntax wrong in "My" variation. The correct is: 37 c7!! xc7 38 xc5+ xc5 39 b7+  a5 40 a1#}
U 37...c7 38 b7+ xb7 39 xc5#
The rook is guarding against the mate at c5,the queen,the mate at b7--so white enters the intervening square and forces black to double cover one square and abandon the other. Sort of a pick-play. |

| whiteshark: <gilbav: The rook and bishop are not similarly-moving pieces> Right. Thanks for pointing it out! :D |
