"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.

And most complex too. About 30 minutes looking it and I not yet understand all the possibilities.
|Jun-26-09|| ||Once: Okay, let's see if we can map all the main variations here. From the starting position ...|

... 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.
Then let's try to interpose the black queen:
31... Qc6 32. Rxc5+ Qxc5 33. Qb7+ Qb6
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.
|Jun-26-09|| ||lzromeu: <once> Tks a lot. Really beautiful puzzle-move.|
|Jun-26-09|| ||whiteshark: Another OTB Plachutta <sleepyirv: Apparently not>|
How about <36.Rc6!!> in Navara vs A Dergatschova Daus, 2007

|Jun-26-09|| ||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.|
|Jun-26-09|| ||Benzol: We know Major Tom's a junkie.|
|Jun-26-09|| ||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
31. Rxc5+, Rxc5
32. Rxc5+, Kb6
33. Rc7, Qe6
34. Qb7+, Ka5
|Jun-27-09|| ||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.
|Jun-27-09|| ||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...|
|Jun-27-09|| ||acirce: That Navara combination is a Nowotny. Also rare in practical games but most likely quite a bit more usual than the Plachutta.|
|Jun-27-09|| ||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.
|Jun-27-09|| ||whiteshark: <gilbav: The rook and bishop are not similarly-moving pieces> Right. Thanks for pointing it out! :D|
|Jul-30-09|| ||WhiteRook48: and declining:
|Jul-31-09|| ||Artemi: Rarely seen move!|
|Dec-10-09|| ||improperchess: hhmmm, what if black takes with the rook??|
|Dec-10-09|| ||improperchess: ok!i'm glad to have a chess player beside me, taking with the rook, the queen would still play qb7 then rxc5#|
|Jan-23-10|| ||Richard Taylor: As on the Kibitzer's Cafe, I found this move myself in the book of Tarrasch's games: I didn't realise it had been Game of the Day. |
When I was trying to find a move here I actually thought of 31. Qa8 - !!
Then I tried R sacs and so on, then I thought "interrupt", and I found 31. Bc7!! Then I went through every defensive move (saying to my son - "That is what a computer would do"...and a Tarrasch of course I could have added... "but a human can "see" these things without necessarily calculating everything, and a computer doesn't get excited or make silly errors (or major blunders)!") but I missed that the King could take the a pawn, but that was - well I must have realised it in the "back of my mind" ! OTB I would have taken much more care...
When I found 31`. Bc7!! I saw Reinfeld's note - and I have to say I agree...
|Jan-23-10|| ||Richard Taylor: When I found this move I was stunned myself. And I kept looking at it and replaying it in my mind over and over...|
It is so beautiful.
But as played through the games I stop at key points or diagrams and try to calculate the moves or find ideas. Here there was a diagram.
The points are:
1.The King at the moment has only one move.
2. How to checkmate? (The aim of the game!! People forget thinking that they need to win pawns etc!)
3. Examine all moves HOWEVER STRANGE OR UNLIKELY - but checks and captures first.)
4. The two big guns are firing down the c file.
5 It would be lovely to be able to check somewhere...say b7.
5A Rxc5+ ... Rxc5+.... hmmmm....
5B Queen jumps to c4 it's mate!!??....hmmm...
6 The king must be made to have NO moves and then I will be able to check and mate...somehow....
So I thought - if only the Q could get to a4 it would be mate.
But no way to get there fast.
So I thought maybe there is a kind of zugzawng here!!?
So after while I thought 31. Qa8!!??? is the R forced to take it? If so there is a mate on c5. But Black at least has 31. ... Bf8. But that "depletes" the defending R's power....interrupts it in fact...
Then I went off that move and I looked at others until I said the word "interrupt"...and I thought "31. Bc7 threatens mate..." Maybe its atht...then, after a while - it is that!! That is the "zugzwang!!
because if the R takes I have a mate on c5 and if the Q takes there is Q sac on b7 and so on... I am always looking for such sacrifices... in fact I have a "collection" of about 20 Q sacs in my games!! (A few were unsound or were one or two movers, others were sound and or were quite deepish))
So I was ecstatic...but I had missed that the King could take the a pawn (as in my mind I had accepted that the B was doling that square) - however OTB I am sure I would have seen that!!
I found all the main concepts!
|Jan-23-10|| ||Richard Taylor: Actually I also considered 31 Qh3, h5 or Qg4 here.
But by seeing 31 Qa8??!!!? and say Rge8 32. Qb8+ Rxb8 33. Rxc5# the seed of the idea of 31. Bc7!! was sown.
|Sep-10-10|| ||sevenseaman: Beautiful game Thanks to <dhotts> cameo comment I was still at sea how the mate were to come about; I had a blind spot about 34. Ra1#.|
|Sep-10-10|| ||Robed.Bishop: <Benzol: We know Major Tom's a junkie.>
Ah, a Bowie fan.|
|Sep-18-11|| ||perfidious: Tarrasch would be remembered in chess history, had he played only this game, for its beautiful conclusion.|
|Feb-15-12|| ||whiteshark: <1.f4> My hand slipped and I missed my e-pawn.|
