Dec-26-05  dakgootje: As some of the previous weeks were maybe a little too hard for the day sometimes, i think this one was maybe a little too easy for a monday. Though its of course good to repeat such positions, so it wasnt meant to criticise the puzzle ;-)

Dec-26-05  Elrathia Kingi: Why doesn't 33.Bg3 hold?

  WannaBe: <Elrathia Kingi> Here is what Shredder said about the position...

33. Bg3 Rxg3 34. hxg3 Nxg3+ 35. Kg1 Nxf1 Kxf1 (-1.33) on infinite analysis.

The best move for white was 33. Be3 Rh4 34. Bf4 Rh5 35. Rf3 Rh3 36. Rf1 Rh5 37. Rf3 Rh3 =(0.00) Also on infinite analysis.

Dec-26-05  EmperorAtahualpa: Nice and easy puzzle! Happy second Christmas Day/Boxing Day! (for those of the applicable countries)
Dec-26-05  Tariqov: <Sneaky> Agree!

Dec-26-05  Tariqov: <erimiro1>i think my suggestion was wrong. As <Confuse> said if 31Rg1?!Rxg1+ Kxg1(or Rxg1) 32Nxf5 which is winning for Black.At move 31 i don't think the White can take back the initiative, or am i missing something??
Dec-26-05  erimiro1: <Tariqov>Right. I missed N:f5. With chronic weakness on f5, and other factors that I've mentioned before, black stands much better (by the way, he stood better much earlier than move 31)
Dec-26-05  Necessary Truths: What about 31. Rxd6!? exd6 32. e7 followed by Bf8? If black ever trades off one of his rooks for the bishop and pawn, it'll be a drawish looking rook and pawn endgame (with black having a small, but probably moot advantage); and if he doesn't, white will always have the threat of promotion which'll tie down either black's king or rook.
Dec-26-05  Richerby: Since this is a Petrosian game, I'll propose 31.♖xd6!? exd6. Fritz gives 32.♗f4 ♖d8 32.h3/a3/a4 (-0.06 to 13 ply). I'd thought 32.e7?! ♖e8 33.♗f8 but that gets a bit messy after 33... ♖g5 and, in any case, Black always has the option of playing ... ♔g8 and returning the exchange to go a pawn up.

Fritz doesn't find any significant improvements to Janosevic's 31st or 32nd move, scoring both as near equality to twelvish ply. It recommends 33.♗e3 maintaining equality after either 33... ♘d6 34.♖xd6 exd6 35.♗f4 or 33... ♖h4 34.♖f3 (0.00/16 ply).

  IMlday: 30.dxe6 looks weak to me as the f5 pawn needs awkward defence. 30.fxe6 would free the ♖s to contest the g-file.
Dec-26-05  lopium: Oh my bad!! I thought we were sunday, and I didn't find it out. lol, that was a monday, and it seemed very simple to me for a sunday (I've thought of the few possiblities), and I saw that, but I didn't know the King couldn't survive with Nf2, because of the rook on g8! I guess the day is a factor of success. When you know it's monday, you'll find it out, but when you are on sunday, that's another story.
Dec-26-05  Necessary Truths: <IMlday: 30.dxe6 looks weak to me...>

Well, if we're going to be looking at even earlier moves, how about 29. Qf4 followed by 30. Rde1 instead of 29. Qe6?!. Black has a backward blocked pawn on an open file; white blunders when he decides to close that file off to attack.

  tpstar: Pardon me, your handle is incomplete. You meant to say "idiot savant" of course. Please make that correction, G.

Monday is supposed to be easy. Anyone who complains is dooming the group to impossible puzzles later in the week.

Dec-26-05  Koster: Just easy enough for th day after Christmas. The finish was about the only thing I understood - Petrosian's moves are not easy to predict.
Dec-26-05  TTLump: <Wannabe> already pointed out that 33.Be3 holds for white, but everyone seems to be looking at alternatives to 31.Rd5 as if that were the major blunder.

I don't think that 31.Rd5 was such a bad move. It helps to solidify white's position as long as the Bishop is on e3. It protects the weak f-pawn and keeps alive the eventual doubling of rooks on the d-file. I think 32.Bf4 was weak, he should have gone directly to e3, but the position is fairly static so there is time for the subtle jockeying of pieces.

Dec-26-05  Whitehat1963: So obvious, yet I didn't see it.

  OhioChessFan: <if 31Rf4 then Rag8 which in my opinion is winning for Black>

<Tariqov>,
32 Rxg4 Rxg4
33 Rxd6 exd6
34 e7 Re4
35 Bf8 Kg8
36 h3 looks really drawish.

  kevin86: I saw what white saw at first-that the sac at f2 doesn't work;however,black just reversed the moves and checked at g1 first. The rook at f1 is overworked. Not quite a smothered mate,but will do until one comes along.
Dec-26-05  dr.noooo: The only reason this puzzle deserves to be here, since it is so easy, and it does deserve its place, is that the piece that makes the entire combo possible is one of Tigrans beloved knights. It was he, remember that said he loved rooks since they could be sacrificed for knights.
Dec-26-05  Tariqov: <OhioChessFan>But after 36h3 Black has winning chancesKf7 and continued with Rxe7.

<TTlump>i agree with you at move 31Rd5 is a OK move, but White made a mistake much earlier making him lose the initiative.

  OhioChessFan: <Tariqov>, I'm at work now and not looking at a board, but after an exchange of Rook, Bishop and Pawn at e7, White can create a fortress with h4, and the King to shuffle along d3-e4-f4-g4.
Jan-04-06  patzer2: Black's 33...Rg1+ sets up a two-move mate, decoying the White Rook to 34. Rxg1 to allow 34...Nf2#.
Sep-20-10  goodevans: 33 Rdd1??

I see from previous comments that this has been a Monday puzzle and that some considered it too easy at the time.

Well Janosevic missed it! 33 Be3 would have staved off the immediate threat.
