|Mar-30-11|| ||cyclon: 36.-Rg1+ 37.Qc1 (if 37.Ka2 [Re1 doesn't change a thing] -Qxa3+ and mates next) -Qd3+ 38.Rc2 Rxc1+ 39.Kxc1 Qxf5, cufflinks.|
|Mar-30-11|| ||David2009: G Sagalchik vs Nakamura, 2003 Black 36?|
I spent some minutes trying to make the thematic 36...Rg1+ 37 Ka2 Ra1+ 38 Kxa1 Qxa3+ Kb1 work: if only I could somehow get my
B to f5 pinning the BQ then Qxb2 would be mate. Then I spotted that after 36...Rg1+ 37 Ka2 Qxa3+! was mate next move by 38...Ra1# irrespective
of how White recaptures. An edge-row mate (hedgerow mate?).

I come late to the party and most all has been said but hey, that's kibitzing. So far this year I have come up with a number of sound and original puzzle solutions. Unfortunately none of my original solutions has been sound and none of my sound solutions has been original.
|Mar-30-11|| ||Patriot: I "solved" it but I'm not satisfied with taking several minutes to see it, even though 36...Rg1+ is the first candidate I considered. I then went down the 36...Qxa3 road and the reply 37.Qxc3 Rg1+ etc. but decided not to go too far with that before going back to 36...Rg1+ again. Then I noticed 37.Ka2 Qxa3+! 38.Kxa3/bxa3 Ra1#.|
There's a reluctance to sacrifice the queen which is one reason I did not consider it right away.
|Mar-30-11|| ||Gilmoy: Bc3 + b4 creates a 3-deep b-wall, which acts like a <virtual Rook> (if the K is trapped on a). That suggests a "two"-Rook mate.|
Bc3 also suggests a triangle mate in the corner.
Both patterns subtask us to bring a first Rook, so <36..Rg1+>. Then it's an Anastasia from behind. Like a scout in Stratego, zooming past a row of immobile bombs!
|Mar-30-11|| ||Whitehat1963: Geez! Two days in a row I couldn't solve the puzzle I suggested!|
|Mar-30-11|| ||kevin86: I saw this one right away;rook checks on first row,king goes to a2. Queen sac at a3 is followed by mate in either of two ways:taking with the king is Ra1# and the pawn captures open up the bishop's support of a1-so Ra1 is mate again.|
36...g1+ 37 a2 xa3+!! 38 xa3 (or bxa3 a1#) a1#
|Mar-30-11|| ||Marmot PFL: Thought it was easier than yesterday, an obvious check (36...Rg1+ 37 Ka2 <forced>) followed by the sac (37...Qxa3+) and the same finishing move (38...Ra1 mate) however black replies.|
|Mar-30-11|| ||stst: 36.... Rg1+
38.Kxa3 or Pxa3, Ra1#
The only way W wants to avoid getting into this grave is 37.Qc1, then naturally RxQ, Bk losing the exchange for a long shot.
<should this be put on Monday??>
|Mar-30-11|| ||EXIDE: Got the sequence of moves correct this time. I also considered the black Queen sacrifice as the leading move, but that fails because then the white Queen can transpose herself between the black rook and white King. Just looking for an alternate, in keeping with this weeks theme, but there is not any. Nice puzzle.|
|Mar-30-11|| ||BOSTER: <sevenseaman> <For me at least,Naka's ability to see 37...Qxa3 is far from the ordinary>.
From the beginning I knew that this picture reminds the well-known episode from game Shirov vs R.,where Shirov having only a few seconds cought the mate on b2,when black could play Ra1+ and after Kxa1 Qxa3 and Qxb2#. In our puzzle b2 is well protected ,but the same idea works if we change the order of moves.
So 36...Rg1+,37 Ka2 (if Qc1 Qd3+) Qxa3 38.Kxa3(or bxa3) Ra1#. Playing 33...c4 Naka could not see that this pawn help to create mating net.|
|Mar-30-11|| ||takchess: Sweet Checkmate! Like <David> I spent time on 36...Rg1+ 37 Ka2 Ra1+ 38 Kxa1 Qxa3+ Kb1 work with no success. It was unclear to me that Ra1 worked at the end. The importance of the advanced pawn which makes this work blocking the escape square b3.|
|Mar-30-11|| ||MaczynskiPratten: A nice game all round. Nakamura's exchange sac with 23..Rxg3 gives him plenty of activity, then 31..cxd5 deflects the c pawn to allow b5 and c4. White thinks he has found an ingenious solution to his trapped Rook with 34 Rxb5 and 35 d6. Maybe he breathed a sigh of relief after 36 Rxf5, and felt secure until the Qxa3+ bombshell! That would be hard to see at move 34...|
|Mar-30-11|| ||takchess: as well as the bishop stopping escape square d4 which wasn't something I took into calculation...|
good rule of thumb. Clearly Note what squares can't serve as escape squares. (squares that are covered)
|Mar-30-11|| ||LucB: <A friend of mine called he solved the puzzle, played through the game and then said, triumphantly, "Nakamura is the American Bobby Fischer."|
I'm not sure what he meant, either>
Don't forget that Fischer was Icelandic... :D
|Mar-30-11|| ||ARubinstein: <LMAJ: His past aside, Nak is one of the world's best players today. This is a very pleasing combination.>|
Ah yes, "his past aside," you mean your own false and slanderous cheating allegations against him because he beat you easily?
|Mar-30-11|| ||Eric Schiller: I've known Hikaru since he was 5 and he constantly amazed me with his tactical prowess. I didn't expect him to pass his brother Asuka but he did. I was lucky to beat him in our only encounter when he was 10. He has fully earned all his honors.|
|Mar-30-11|| ||Penguincw: Nice puzzle.I was thinking 36...c5 for the following reasons:|
1.It allows the bishop to attack the rook.If that rook would be allowed to capture,white will lose the exchange and bring their queen away from attacking the bishop.The bishop would then have time to move out of the way.
2.It's getting ready to hop into the weakest point in the white camp,b3.
From there,it would be taking away 2 squares from the white king.Also,it is within attacking distance of all 3 major pieces for white.The knight would like to get to d4,which would form a deadly fork.It's also within checking distance (d2).
3.It closes up the diagonal against the black king.At some point,white might gets their queen on the g1-a7 diagonal and maybe start checking black's king around.

But 36...Rg1+ is the winning move.
|Mar-30-11|| ||morfishine: <Penguincw> I haven't analyzed your continuation but i like your thought process. For all we know, it wins too, and thats what counts: its good practice (over here) in that we may be able to profit/capatilize in the other game going on...:) Morf|
|Mar-30-11|| ||Penguincw: Thanks. :)|
|Mar-30-11|| ||MaxxLange: reverse the move order of the familiar pin trick with ...Ra1+ and ....Qa3+ and hey, it's mate|
|Mar-30-11|| ||morfishine: <David2009> Good work! We'll need that in the other game going on. <Unfortunately none of my original solutions has been sound and none of my sound solutions has been original> Doesn't matter as long as we win. Morf|
|Mar-30-11|| ||MountainMatt: Wow. I barely got Monday's, was stumped yesterday, but here, 36. Rg1+ 37. Ka2 Qxa3+ with mate to follow jumped right out. Not sure what to make of that, but whatever, I'll take it!|
|Mar-30-11|| ||TuxedoKnight: i guess i will go to http://tuxedoknight.uphero.com
|Mar-30-11|| ||morfishine: <TuxedoKnight> Went to your site! Tough puzzles...took me awhile to get 14/19|
|Mar-30-11|| ||Fuegoverde: 36... Rg1+ and white must loose his queen with 37 Qc1 or if 37 Ka2 Qxa3+! and mate in the next move.|
