|Jul-14-07|| ||DexterGordon: Wait, I think your (B) has the answer to why White plays b4 and c4, <black knight c6>. With the Black queen on b4, if 29...Rae7, then Ne6+ wins the queen.|
|Jul-14-07|| ||crazy monk: <That's a different Tigran?> Is he relates to the "original" Petrosian?|
|Jul-14-07|| ||outplayer: What should I say? easy saturday ;-)|
|Jul-14-07|| ||desiobu: I the right first couple of moves but I couldn't finish it. Really pretty finish.|
|Jul-14-07|| ||noTALent: I considered both Bxh7+ and Rxa5 as my probable best moves, but didn't look at it long enough to get them in correct order. Might have gotten that far if I had the time... But the rest was filled with so many permutations...|
|Jul-14-07|| ||melv: <black knight c6> 27 b4 deflects the Q from gaurding the bishop on d8 so now black cannot use the rook to interpose on e7. He has to us the bishop which then blocks the rook on a7 from gaurding f7.wow my head hurts|
|Jul-14-07|| ||TrueBlue: Rxa5 and Bh7+ both give decisive advantage to white ...|
|Jul-14-07|| ||bogo78: i've seen the first 3 moves but after that the picture become blurry, as there were too many variations to check. b4 and c5 ideas did not cross my mind, I guess i was probing waters way out of my calculation horizon.|
|Jul-14-07|| ||Peligroso Patzer: <crazy monk: <That's a different Tigran?> Is he relate[d] to the "original" Petrosian?>|
From the biography at: Tigran L Petrosian:
"Tigran Petrosian (no relation to the late World Champion Tigran Vartanovich Petrosian) was born in 1984 in Armenia."
|Jul-14-07|| ||TommyC: I got the basic idea quickly, but didn't attempt the details.|
Btw, is this opening really "The English Attack"? I thought that normally involved Be3 w f3 and O-O-O (barring earlier deviations eg 6...Ng4) not f4 and O-O? Seems like its transposed out of it, if memory has served me alright.
|Jul-14-07|| ||fm avari viraf: I saw it differently 24.Bxh7+ Kxh7 25.Qh5+ Kg8 26.Rxa5 [Qxa5 is not playable because of 27.Qxf7+ ]so 26...g6 & 27.Qxd5. But the text moves were simply far away from my imagination|
|Jul-14-07|| ||kevin86: Could we call this Tigran L Petrosian "The little Tiger"?|
A great combination-but I wouldn't have found it in a thousand years.
|Jul-14-07|| ||Edeltalent: I got the exact same solution as <pittpanther> and would have had to work for the win.|
Now to recap the situation after the better 27.b4: the black Queen has to...
... avoid the square b4 because after 28.Qd6+ Be7 is necessary, blocking the Ra7 from f7 and ending like the game
... avoid the seventh row, as this is blocking the Ra7 from d7, resulting in 28.Nd7+ followed by Bc5+
... keep an eye on c5 to prevent the same Nd7+/Bc5+ combination.
So the best choice seems to be the odd 27...Qb6, moving right into the range of the white Bishop. Does anyone have a decisive answer to this? I can't figure out anything better than a transformation to <pittpanther>'s aforementioned Q vs R&B variation.
|Jul-14-07|| ||MostlyAverageJoe: <fm avari viraf: I saw it differently 24.Bxh7+ Kxh7 25.Qh5+ Kg8 26.Rxa5>|
While, as you said the rook on a5 is untouchable, black has this:
26 ... Re5! and white will lose one of the rooks, no matter what:

Black's choices are now: (1) give up the a5 rook, or (2) save it by losing an exchange on f7 and getting a pawn in the balance.
|Jul-14-07|| ||PAWNTOEFOUR: yeah,i know it's saturday and i should be resting up for monday's puzzle...but no, i had to try this.....white sacrificing this and that makes you wonder how is he going to get it done...but he did..nice puzzle|
|Jul-14-07|| ||MostlyAverageJoe: <pittpanther: I saw this sequence but with a different finish. On 27 I was going to play 27 Nd7+>|
Yeah, this was also my idea, although I did not dive into details as deep as you did - the line just "felt right." Now, looking at the resulting position, I think I might have seen b4, but I also see another strong move for the white, with a continued mating threat on f7:

What can black do now?
27 ... Bf6 - then a knight check wins the black queen.
27 ... Qc7 - then 28.Qh5 and the black is in trouble once the king gets chased out into the e-file.
27 ... Be6 - then 28.Nxe6 and now all white's pieces get into action
27 ... Ree7 - then 28.Qh5 again, maybe preceded with b4 to provide defense to the vulnerable knight on c5.
and i don't see anything else looking any better.
|Jul-14-07|| ||MostlyAverageJoe: <Edeltalent: ... after the better 27.b4 ... the best choice seems to be the odd 27...Qb6>|
Indeed, when I plugged this into Hiarcs, it tells me that this line is the best for the black:
27. ... Qb6 28. Nd3 Be6 29. Qe5 Qb5
and black loses the rook, but the difference between the above and the second-best Qb5 is slight (+6.56 and +6.80) and black is losing soon.
|Jul-14-07|| ||whiteshark: <MAJ> Your move <27. Bg6!> is really devastating !|
|Jul-14-07|| ||Fezzik: Wow!
I got lost in the forest after 27.b4. I felt I was on the right path, but couldn't actually see it. What a brilliant game by Petrosian!
(24.Ra5! creating the real threat of 25.Bh7 is reminiscent of Petrosian's Latvian contemporary and one-time world champion!)
|Jul-15-07|| ||ALEXIN: Great combination beginning with 2 sacrifices. I saw 24.Rxa5 but then I thought 25.Qh5.|
25. Bxh7 is more direct !
|Jul-15-07|| ||Kings Indian: Very nice. The loose pieces all over the board in black's position and the activity of white's pieces made a lot of the ideas obvious. I didn't get it all the way of course, but i learned a few things.|
|Jul-15-07|| ||patzer2: Petrosian plays the deflection sacrifice 24. Rxa5!! to set up the winning demolition that follows after 25. Bxh7+!|
The finish with 30. Rxf7+! makes for one of the more clever mates (mate-in-three in this case) ever played by a world champion.
|Jul-15-07|| ||Davolni: <The finish with 30. Rxf7+! makes for one of the more clever mates (mate-in-three in this case) ever played by a world champion.>|
<Patzer2> I hope you this is not the 9th world champion Tigran V Petrosian.
A very impressive game indeed by young Tigran L. Petrosian!!! Nice sacrifices indeed!!!!!
|Jul-15-07|| ||Crowaholic: I really thought the solution starts with 24. Bxh7+ Kxh7 25. Qh5+ Kg8, but according to computer analysis, this is probably losing. Playing 24. Rxa5! first, deflecting the BQ (or else winning a piece), is much better. Now the BK cannot take the bishop or is swiftly checkmated in a sort of windmill (well, not precisely): 25. ..Kxh7 26. Qh5+ Kg8 27. Qxf7+ Kh7 28. Qh5+! Kg8 29. Qxe8+ Kh7 30. Rf8 and now ..Kh6 is forced because of the double threat of Qh5# and Rh8# (or a mate in 2 after Black moves the g pawn). Then, 31. Rh8+ Kg5 32. Rh5+ Kf4 (..Kf6 33. Bd4#) 33. Qe5+ Kg4 34. h3#. Alternatively, 32. ..Kg4 33. h3+ followed by Qe5#.|
24. Bxh7+ Kxh7 25. Rxa5 Bf6 seems to merely win a pawn (although I didn't run a deep search).
<MostlyAverageJoe: Second try - reverse the sequence: 24. Rxe7>
Is that Raxe7 or Rfxe7 with which you take the non-existing piece at e7? Sorry, could not resist, if you know what I mean...
|Jul-15-07|| ||MostlyAverageJoe: <Crowaholic> Yeah, I sure know what you mean :-)|
I have no idea how I managed to change Rxa5 into Rxe7, since the latter does not occur in any line I considered.
