| Apr-17-10 | | sethoflagos: The first move to catch the eye is <42. Rg6> threatening <43. R4xh6#>. Black is obliged to respond with a check. Not 42. ... Rxh2+ obviously, but either <42. ... Rb1+> or <42. ... Rf1+> would do the job. <43. Rg1> is forced and the checking black rook can return to the second rank to restore the position of two moves prior (43. ... Rxg1 would I think be advantage white). But can we make this motif work by deflecting one of the black rooks with a sacrificial pawn advance? <42. b6> threatening <43. bxc7> must force <42. ... Rxb6>. This does not free up a <43. Rb6> initiated mate (<43. ... Rb1+ 44. Rg1>) but lifts the threat of immediate mate on h2 permitting <43. Rhg4> and a g-file rook shuffle mate threat reminiscent of last tuesday's Smyslov/Boleslavsky puzzle. Black has no useful check and the pawns are blocking defence. <42. b6 Rxb6

<45. Rg7+ Kh8
46. Rg6 Kh7
47. f6 ...> threatens 48. Rg7+ Kh8 49. f7 and the follow up 50. Rg8+ Rxg8 (50. ...Kh7 R1g7#) 51. fxg8=Q# forces 49. Rxf6 Rxf6 
click for larger viewSo the puzzle reduces to proving there is no drawing defence for black from the above position. Only one move neutralises the f-pawn. <47. ... Rf8>
and now
<48. Rg7+ Kh8
49. Rxc7 ...> threatens 50. Rg6 Rxf6 51. Rxf6 and easy pawn promotion (50. ... Ra8 51. Rxh6+ Kg8 52. Rg7#)

| Apr-17-10 | | BOSTER: White have more space and coupe "hanging" extra pawns,but black rooks on the second rank and white rook on h4 is tied up with defense against Rxh2#.
The idea to create the way to move c pawn to c8.
Therefore: 42.b6 Rxb6
43.Rhg4 Rb8
44. Rg7+ Kh8
45.f6 Rxf6
46. Rxc7 Rf2
47. Re1 Rg8
48Rd7 Rc2
49.c7 Rc8
50.Rd8+ and White wins. |

| Apr-17-10 | | hulkweazel: I didn't look at all the variations but I got it after about 15 seconds. It's pretty easy when you see a mating attack with your rooks, but you need something to break up black's rooks and b6 is pretty much the only move you can do. Maybe there are different variations that make it much more difficult, I guess. |
|
| Apr-17-10 | | tacticalmonster: 1) Black two pawns deficit was compensated by seventh rank doubled rooks. 2) White had a useful passed f pawn controlling the g6 square and blocking the retreat square of the f rook. 3) White could make a protected passed c pawn with b6 4) If one of the rooks was not in the seventh rank and the f pawn was still there, White forced checkmate with Rg4 candidate: b6
1 Rxf5? 2 bxc7 Rf8 3 R4g4 Ra2 4 Rg7+ Kh8 5 Rg8+! Rxg8 6 Rxg8+ Kxg8 7 c8=Q+  1 Rxb6? 2 R4g4 h5 3 Rg7+ Kh8 4 Rg5- forced mate
1 cxb6 2 Rc1 Rbc2 3 Rxc2 Rxc2 4 Rg4! b5 (4 Rf2 5 Rc4) 5 f6- winning |
|
| Apr-17-10 | | Eduardo Leon: I would have loved to see the following variation in the game: 42...cxb6 43.♖c1 ♖bc2 44.♖xc2 ♖xc2 45.♖g4 b5 46.♖g6 b4 47.♖xd6 b3 48.♖d7+ ♔g8 49.♖b7 b2 50.♖xb2 ♖xb2 51.c7, and the black king is one square too far away to help the rook stop the pawns: 51...♖c2 52.d6 ♔f8 53.d7. |

 | | chrisowen: Iron Tigran steams after probably 42.b6. Burn er the pawn, thrust of which impressing the tower to jettison off and capture it. Slowly bled dry rg4 then adds gasoline. Scratch Rb2 in light of sixth rank zip point, he pockets the gfile once rook flees. Hone your KID Gligoric needs a good ticking off. |

| Apr-17-10 | | rapidcitychess: It seems I have an eye for these. b6 right away. |

| Apr-17-10 | | babakova: 1) 1.b6 Txb6 2.Thg4 h5 3.Tg5 Kh6 4.Tg7 h4 5.Tg6+ Kh7 6.T6g4 2) 1...cxb6 2.Tc1 Tbc2 3.Txc2 Txc2 4.Tb4 Tc5 5.Txb6 Txd5 6.c7 Tc5 7.Tb7 3) 2...Tb8 3.Tg7+ Kh8 4.f6 h5 5.Tg7+ Kh8 6.f7
were the ones i looked at |

| Apr-17-10 | | wals: Rybka 3 1-cpu: 3071mb hash: depth 16:
Black's move -
41...Rab2 + 4.99 was costly.
Rac2 + 0.88 was better.
if played out the game could have went :-
45.Rdg6 Kh7 46.f6 Rf8 47.Rg7+ Kh8
48.Rxc7 R2xf6 49.Rd7 Rc8 50.c7 h5
51.Rd8+ Rf8 52.Rxf8 Rxf8 53.Rb1 Kh7

| Apr-17-10 | | wals: There are many instances of very young children paying attention to chess at their fathers knees, so to speak. Then at a very young age they play and are very successful. There is no doubt that they have learned a second language, in this case, The language of Chess, and have built a
strong language system in their brain for it. When at times we may ponder... they know. http://www.education.com/reference/... |

 | | agb2002: White is two pawns ahead.
Black threatens to take the pawns on b5 and f5.
The white rook on g1 cuts the black king (and also the white king) but the other rook plays the passive role of defending h2 from ... Rxh2#. White can divert one of the black rooks with 42.b6 or 42.f6. The f-pawn can create problems to the black king. Therefore, 42.b6: A) 42... cxb6 43.Rc1 Rbc2 (otherwise 44.c7 followed by c8=Q) 44.Rxc2 Rxc2 45.f6 and the rook can't stop both pawns. B) 42... Rxb6 43.Rhg4 Rb8 (43... h5 44.Rg7+ Kh8 (44... Kh6 45.R1g6#) 45.R7g5 + -) 44.Rg7+ Kh8 45.R7g6 Kh7 46.f6 Rf8 (otherwise 47.Rg7+ Kh8 48.f7 followed by Rg8+) 47.Rg7+ Kh8 48.Rxc7 and the c-pawn should decide the game. |

| Apr-17-10 | | gofer: This all looks a little straight forward.
42 b6 ...
42 ... cxb6 43 Rc1 Rbc2 44 Rxc2 Rxc2 45 Rg4 winning as Rxc2 cannot stop Pc6 and Pf5. 42 ... Rxb6 43 Rhg4 Rb8 (h4 44 Rg7+ Kh8 45 Rg5 mating) 44 Rg7+ Kh8 45 Rg6 Kh7 46 f6 Rf8 47 Rg7+ Kh8 48 Rxc7 winning 42 ... Rxf5 44 cxb7 Rf8 45 Rg4 Rbf2 46 Rg7+ Kh8 47 Rg6 Kh7 48 Rxd6 winning Time to check... |
|
| Apr-17-10 | | Eduardo Leon: <gofer>, in your 42...♖xf5 43.bxc7 ♖f8 <44.♖f4!> is better, since it forces black to lose one tempo moving his rook. |
|
| Apr-17-10 | | Eduardo Leon: <agb2002>, in your 42...cxb6 43.♖c1 ♖bc2 44.♖xc2 ♖xc2 line, <45.♖g4> is a fundamental step. If 45.f6 directly, the rook cannot stop both pawns at the same time, but the king can approach the f pawn: 45...♔g6. |
|
| Apr-17-10 | | tratra: Petrosian vs Glicoric;
Very Difficult;
White and black each has 2 rooks but white has 2 extra pawns one backward and one unopposed but both are attacked from behind by the two black rooks. Both kings are restricted on the h file so centralization is not yet possible. White's rook on h4 is tied on guarding mate on h2 but if white can only disorganize black's rook battery on the 2nd rank he himself can create mate threats on the g file. Its other rook, although free to move on its backrank can't be lifted aside from g file for there is a bank rank mate threat as well. Candidate moves: 42. b6 and 42. f6
42. b6
a. 42..Rxb6 43. Rhg4 h5 44. Rg7+ Kh8 45. Rg8+ Kh7 46. R1g7+ Kh6 47. Rxc7 (..Rb1+ 48. Rg1 Rxg1 49. Kxg1 Rxf5 50. Rc8! Rxd5 51. c7) Rxf5 48. Rcb7
b. 42..cxb6 43. Rc1 Rbc2 44. Rxc2 Rxc2 (45. Re4 Kg7 46. Re7+ Kf6 47. Re6+ Kxf5 48. Rxd6 b5 49. Rd7 Ke5 50. Rb7 Kxd5 51. Rxb5+ Kxc6 =) 45. Rg4 And black should stop 2 passed pawns 42. f6?!
42..Rxf6 43. Rhg4 (..h5 44. Rg7+ Kh6 45. Rg8=) Rf7 44. Rg8 Rxb5 45. Rd8 Rxd5 46. Rd7 Rdf4 47. Re1 Kg6 48. Rxf7 Kxf7 black having the advantage Let me compare my analysis |

| Apr-17-10 | | jimmyjimmy: I had absolutely no clue about this puzzle. I still have not got any of the daily puzzles right. I am a novice. I was in zigzswan. Did I spell that correctly? I just didn't have any good move that I could see. That is why I am on this site. I want to learn. I am looking forward to the World Chess Championship in Sofia, Bulgaria. |
|
| Apr-17-10 | | Eduardo Leon: <jimmyjimmy>, Zugzwang is not about a state of the player, it's about a state of the position, in which the one who has to move must make a move that actually worsens his position. In other words, if he could play a "null move" (skipping as in a domino game), he would be better off. Don't worry about not solving puzzles. Start with Monday ones. Once you're confident you can solve them without much effort, start solving Tuesday ones, Wednesday ones and so on. |
|
| Apr-18-10 | | njchess: The ending is vintage Petrosian in that he creates a threat that cannot be ignored which simultaneously diffuses his opponents attack and gives him a winning position. Brilliant. |
|
Apr-18-10
 | | doubledrooks: I went with 42. b6, with the idea that after 42...Rxb6 the white rook on h4 could get out of its purely defensive role of guarding the h2 square. After 42...Rxb6, a sample line I found is 43. Rhg4 Rb8 44. Rg7+ Kh8 45. R7g6 Kh7 46. f6 Rf8 47. Rg7+ Kh8 48. Rxc7 R2xf6 49. Rd7, threatening c7 and Rxd6. |

| Oct-12-10 | | twin phoenix: Just thought my learned colleagues would like to know that Tal mentions this game in his book. "Life and Games of Mikail Tal". He states that Petrosians play in this game had put the King's Indian Defence into a hard place. The essential pawn break on C5 is strong and played a pivotal role in the Tal game in the book that mentions this game. (Don't remember Tals opponent but it was from same time period.) Tal was very complimentary of Petrosians analysis of this position and this opening. |
|
| Oct-14-10 | | twin phoenix: remembered over night who Tal's opponent was...
FISCHER!!!
lol took one look at the book and remembered before going any farther. The game here and the Tal-Fischer game are quintessential games for this opening. |

| Nov-03-10 | | Rick360: I'm working hard to improve my Chess and my endgame in particular. This gem from the great "Iron Tigran" merits study! |

 | | plang: 9..a6 is rarely played anymore; nowadays 9..g5, breaking the pin, is the main line. This was the last of four games with 12 b4 in the tournament; White won all four. 12..f5? 13 exf..gxf 14 Bh5 would have cost Black material. Played in the 28th (last) round; four rounds earlier Olafsson had played 17 cxd against Gligoric. 17 c6 was Petrosian's improvement. 21 a4 would have avoided the complications that B;ack initiated with 22..b5. 32..Kh7? would have lost to 33 Rce1..Qf7 34 Ne4!. 37 Nd4? allowed Black to activate his rooks; 37 Nc3..Rc2 38 Nb1..Re7 would have been better though Black would still have had decent drawing chances. As mentioned earlier in this thread 41..Rac2 would have avoided the concluding combination and would have likely led to a draw. |

The only convincing theory is that he has a progressive mental illness. Some people claim he uses software but strangely enough absolutely nobody can cite an example of any software that comes close to his style. |
