 | | LoveThatJoker: I would like to start off by saying that I love the fact that this is a Radjabov puzzle - as he is one of the best in the world - and that it is also an Endgame puzzle. The best tactical idea I can come up with is <60. b6!? Ra8> [60...Rxa4? 61. b7! Rb4 62. Rc4+!! Bxc4 (62...Rxc4 63. Nxc4 and 64. b8=Q wins) 63. Nc2+ K moves 64. Nxb4 and 65. b8=Q winning; 60...Rb7 61. Rc6 and White is winning as he threatens to consolidate with a5 immediately as well as having certain consolidating N manouevres at his disposal if Black allows it (i.e., 61...Ba6? 62. Nc2+! followed by 63. Nb4); 60...Ra6 61. Rc6 (threatening 62. b7) 61...Ra8 62. b7! Rb8 63. Rb6! Kc5 64. a5 and White is definitely winning as he can still actively position both his N and K!] <61. Rc7> is an excellent waiting move that keeps all of the options I've demonstrated above open. Examples of this are 61...Rb8 62. a5 with the advantage, 61...Ba6 62. a5 again with the advantage as 62...Bc8 63. Rxc8 Rxc8 64. a6 wins LTJ |

| Mar-09-12 | | Gypsy: <joupajou: Saw 60.b6, but put my bets on the wrong horse (60. ..Rb7). ...> That is what I have considered the main variation:
<60.b6 Rb7 61.Rc6...> and <a4-a5> followed by <Ne3-c2> wins pretty much against anything that Black tries. (The Q side pawns can not be stopped.) |
|
| Mar-09-12 | | M.Hassan: "Difficult" White to play 60.?
White has a Knight + a pawn for a Bishop
60.b6
<if...Kxc3 bxa7 and the a7 pawn will be Queen> 60.............Rb7
61.Rc6 Ba6
62.Nc2+ Ke5
63.Nb4
Knight sits on a superb square
63............Be2
64.a5
a & b pawns are again connected. The game obviously takes longer. My guess is one of the pawns will be promoted
1-0 |
|
| Mar-09-12 | | ZachSears: 60.b6 was obvious or at leas the first thing I saw, but 60... Rxa4? wasn't nearly as good as 60...Rb7 |
|
| Mar-09-12 | | M.Hassan: In the actual game:
62.Rc4+ is a very neat and ingeneous move
62.............Bxc4
63.Nc2+ and winning Black Rook and no other Black piece can stop promotion of the b pawn
Marvellous |

| | LoveThatJoker: I'm glad I found the puzzle solution and netted the full point today. This being said, 60...Rxa4? was obviously not Karjakin's best: 60...Ra8, 60...Rb7 or even 60...Ra6 would have been much stronger (I see that other kibitzers have really been keen on 60...Rb7 when, as we all are agreeing, 61. Rc6 is called for). I certainly would enjoy reading fellow kibitzers' comments on my analysis. LTJ |
|
| Mar-09-12 | | rilkefan: Couldn't find anything except slogging after 60.b6 Rb7 61.Rb3 (or maybe Rc6, keeping the black king away). |
|
| Mar-09-12 | | Once: Too clever for me in the little time I had this morning. I instinctively wanted to play 60. b6 for a number of reasons: 1. It's a passed pawn and passed pawns must be pushed. 2. Black can't play 60...Kxc3 61. Bxa7. And as we saw yesterday, we ought to be interested in variations which contain moves our opponent cannot play. 3. The Rc3 is attacked and it's a puzzle, so that's bound to mean that we ignore the threat to the rook. But I didn't know what to do if white played 60...Rxa4, not seeing the cute b7/Rc4+ idea. Good puzzle. Nul point for me today. |
|
| Mar-09-12 | | galdur: Was watching this live at the time.
60.b6 Karjakin moved Rxa4 and was hit by that nice combination. If 60...Rb7 61.Rc6 and black seems defenseless against a5, Nc2-b4, a6. If 60...Rd7 I think Rc8, Ra8, Ra7 is simple enough. Black is pretty helpless. |
|
| Mar-09-12 | | viking78: First of all, I'd like to thank to amaurobius, MemetheCat, SimonWebbsTiger and of course Once for their friendly posts from yesterday addressed to me, your posts really helped me A LOT.
Back to today's puzzle, well white has two pieces attacked and unprotected: a4 (pawn) and c3 (rook). I see only one moove which protects both which is 60.Ra3, but that is not good because 60...Bxb5. So I only think of <60.b6>, if KxR, pXR, then Q promotion on a8 can't be stopped. Black has now 2 options: 60...Rb7 or Rxa4. If Rb7 then 61.Rc6 followed by 62.a5 and 63.Rc7, so I think black prefer 60...Rxa4. Now 61.Rc7, if Rb4 62.b7. 62...Ba6 not good beacuse 63.Nc2+ K@R fork, so 62...Rb2 63.Rxf7 Ba6 64.Rf6 Bxb7 Rxg6. Maybe 61....Ra8 62.b7 Rb8 63.Rxf7 Ba6 64.Rf6 Bxb7 65.Rxg6. I end up in same position I don't think game went this way, time to check, hope I was right at 60.b6 which is good for a Friday for me. |

| Mar-09-12 | | gofer: White has two free-flowing passed-pawns, black on the other hand has Pe4
which is neither. The only question is how to progress our pawns. Well there is one bad move...
60 Rxd3 exd3?
There are a couple of pretty bad moves...
60 Ra3 Kc5 (Bxb5? 61 axb5 Rxb3 62 Nc2+  ) looks like a draw 60 Rb3 Rxa4 61 b6 Ra8 62 b7 Rb8 looks like a draw
60 Rc7 Rxa4 61 b6 Rb4 62 b7 f6 63 looks like a draw
So lets go for something else!
<60 b6 ...>
60 ... Kxc3 61 bxa7 promoting
60 ... Rb7 61 Rb3 winning
<60 ... Rxa4>
<61 b7! ...>
A truly wonderful pawn push. Black must have been horrified to see this
one as only at this point does black realise the the pawn can't be
stopped!!!
<61 ... Rb4>
<62 Rc4+!! ...>
Time for black to resign. The pawn will promote as the bishop can't stop
it and the rook is about to be taken off the board.
<62 ... Bxc4>
<63 Nc2+ ...>
A very pretty finish that took me about 20 minutes to find... Time to check... |

| Mar-09-12 | | Robespierre: "Once", the Prince of Prose, took my assessment -- which was, "Very clever!" Similar to him, I got '60. b6', but that's where I was stymied. |
|
| Mar-09-12 | | viking78: Yup, got the 60.b6 and after seeing the continuation it looks so natural, too bad I didn't discovered 61.b7. Anyway I wouldn't saw 62.Rc4+ which is a beauty move! (I would have played 62.Rc7)
PS I hope my grammar errors don't bother people too much, I still need to improve both english and chess strenght :) |

| Mar-09-12 | | SimonWebbsTiger: @<galdur>
hehehe, is it a bad thing to have watched the game and know what's coming? I recognised it immediately from this year's Tata because I watched it on line too! @<Viking78>
no worries about your spelling, etc. There are lots of posters from around the world on cg.com for whom English isn't a first language. Glad also to have helped yesterday. |
|
| Mar-09-12 | | SimonWebbsTiger: I concur with others: 62. Rc4 is the sort of move everybody would love to uncork; I remember lots of people on line at the time who didn't see Teimor's beautiful combination, including myself! |
|
| Mar-09-12 | | Rook e2: I remembered the game! |
|
| Mar-09-12 | | viking78: Where I can watch games online between masters? Is there a schedule somewhere to know when theese games will took place and where to follow them online? |

| Mar-09-12 | | SimonWebbsTiger: @<viking78>
cg.com premier membership, apart from offering more features, allows you to follow a live broadcast game. Sometimes they enlist the help of Natalia Pogonina in the kibitzing. Another way is via the Free Internet Chess Server (aka FICS). Also, many top tournaments have live transmission of the games. Notable examples - with GM commentary - are the US Championship and the London Chess Classic. Then there are commercial options such as the Internet Chess Club (ICC) and playchess.com (the latter is Chessbase's server) which always feature live GM commentary. So there are lots of options depending on your wallet. The FIDE web page has a calender of events. |

| Mar-09-12 | | David2009: Radjabov vs Karjakin, 2012 White 60? White has a promotion tactic: 60.g6 Rxh4 61.g7 Rg4 62.Rc4+ Rxc4 63.g8=Q with what should be a reasonably easy win.
Easy to miss if you are defending. Evolution has made us humans optimists (a survival tactic): its downside in
chess is that we miss combinations from the other side. Back when priorities permits to set up a Crafty interactive link see how Crafty will defend. |
|
| Mar-09-12 | | whiteshark: Fine endgame tactics by Radjabov. |
|
| Mar-09-12 | | galdur: I think Karjakin did his best to avoid a draw in this game, for example 32...a4 would have been very safe and good. |

| Mar-09-12 | | Boomie: <viking78: Where I can watch games online> This site is a good, free place to watch games from any current or recent tournament. http://livechess.chessdom.com/site/ |
