Apr-12-05  cjhasbrouck: I got this one pretty quickly.

Queen traps like this are so rare for me.

  cu8sfan: My plan was correct but I tried to trap the queen with 32.Bg5 Qh5 33.g4 Qh3 34.Ng1. Now I see that 33...Nxg4 seems to be the problem in that line. O well... Better luck tomorrow.

I got the underpromotion week prediction wrong, too. Haven't found the theme of the week yet.

Apr-12-05  Simplification: <cu8sfan> Maybe this weeks theme is the stranded/helpless Queen - also with a possible link with last weeks Royal Wedding!?
Apr-12-05  dunforgiven: i'm not happy with this puzzle one bit. there's a whole bunch of moves that anybody could have made and pinning each successive move correctly is just WAY above my playing level :(

i was only able to go as far as trapping the queen and that's it

Apr-12-05  Marvol: Yeah, I got this one - well the first two moves :-P that is...

<cu8sfan: Haven't found the theme of the week yet.>

I agree with above poster that it looks like 'winning the queen' week (the never-played knight fork to win the queen yesterday).

Apr-12-05  aw1988: I got Bf4 as an answer too... according to patzer2, this also works. Does d5 have merit?

  Richard Taylor: The queen trap was easy to see but the problems I saw were eg 32. Bg5 Qh5 33. Ng3 e:f3 34. Nxh5 K:g2 35. f:g2 36 K:g2 Nd5+ 37. Kg1 R:c2 threatens to win on R-g2+ but there is 38. Qxc2 N:c6+ 39. Nf6+ Kh8 and White has some problems (in other words there were some dangerous threats that Petrosian had to make sure weren't going to work )

So I thought that 34.fxg3 was needed..amd once one is in this 'tunnel' eg does Qxf3+ work etc or N:d5 25. Rxc8+ Kg7 26. Nh5+

But I overlooked the defence of 35. Rc:g2 -but if I had seen it 36. Nxd4 has to be checked The impressive part of this is White seeing all these various threats and knowing that he could win (that he could defend Black's potential attack) by the "obvious" Bg5 of course - the basic idea of trapping the Q was straightforward...but variations have to be checked - very hard for most players to do over the board in the tension of a game. I was so busy looking at the potential attack by Black I missed the Rg2 defence... In attacking you need to know how to defend.

This was an execllent game by Petrosian.

  patzer2: <who> After 32. Bf4! exf3 33. Rxf3 Re6 34. Bg5! Qe4 35. Bd3 Qd5 36. Bxf6 , White wins easily (+3.66, Fritz 8 @ 13 depth).
Apr-12-05  aw1988: Hooray!
Apr-12-05  Ericsupreme: yeah this is a little out my league also. i need a mate in 3 or less for now but i'll get there someday if i keep playing and studying ...hopefully :)

hey can someone please explain to this rookie why not 33.Nf4 to trap the queen? would appreciate it thanx!!

Apr-12-05  blunderqueenagain: <Ericsupreme> 33. Nf4 is met with Qxg5, a win for black.
Apr-12-05  Ericsupreme: never mind the bishop would no be longer protected....see i'm definitely a rookie. must study longer....lol
Apr-12-05  Ericsupreme: thanx blunderqueenagain i saw it after i posted the question...

  Swapmeet: <dunforgiven> I think as long as you get the queen trap you solved the puzzle. Black obviously should have resigned on move 32.

  beenthere240: there may have been a time issue since black threw in the towel after move 41.

  kevin86: I first looked at a combination to take the knight at c6-then I saw that black's queen was isolated and overextended.

CAPTURE the queen week--a good idea to "honor" a royal marriage.

Apr-12-05  Ezzy: What a mess black got into. His pieces are trapped or pinned into submission! 16..g6?! Unnecessary weakening of the black squares around his king. 18..Qe8?! <Allows 19 e4! because the black queen no longer attacks the d4 pawn.> 19.Nf1?! <19 e4 is strong> 27..Nf6?? <Allows 28 Nf4 Re7 (If 28.. Re8 29 Bb5 Rc8 30 e4 and wins) 29 Bb5 Nd8 30 Bb4 Rde6 31 Nxe6+ With a massive advantage.> 28.Rf1? <As mentioned in the previous note 28 Nf4 is decisive> 29..Kg8?? I think black had to try <29..a6 at this point.>
Apr-12-05  Giearth: Agree with <Ezzy>. 19.e4 should avoid the above ending. Many bad moves, IMHO. :)
Apr-12-05  Stonewaller2: I like that Black didn't resign. "Think you can finish me with ♕ against ♘, eh, c'mon and show me." And as pointed out there's a dance in the old dame yet after ... ♘xd5.
Apr-12-05  tjshann: Well, I got the first two moves to capture the Queen, but I didn't calculate nine moves ahead to the final position (I wonder if Petrosian did, or just "knew" instinctually he had a win.) It is amazing that the White King is able to boldly move off the back rank to threaten the Rook in this position.
Apr-12-05  aw1988: You need not calculate to the final position.

  Richard Taylor: <tjshann> they make a lot of calculations checking for counter-measures but don't neccesarily see every move ..Petrosian an players of his calibre just see more than the rest of us -I'm presuming there are no GMs kibitzing on this one! he would see a lot of lines -not neccessarily all that was played - both players played better than we give credit; one move that is a bit "mysterious": why Petrosian play Kh1? - he never used g1 so it may have been a waiting move or for his knight - this kind of game is instructive for tactical players as its NOT so tactical -how to play when there is no obvious attack etc although I suppose Karpov is another example and many of Fischer's games are a mix - Petrosian tended to play more manoevering lines - such play worked against Botvinnik but not Fischer so well... hmmm ...an interesting game but perhaps not one of the "great" games
Apr-12-05  THE pawn: OH!
I got it, you know how to solve puzzles? Hear this: Just do the most unimaginable thing to do, and you get it! That's the first thing I looked for, something absolutely illogic to play, I found out the bishop and clac, queen trapped.
Apr-14-05  Stonewaller2: Last nite CM8K threw 32. ♗g5 ef at me after which 33. ♖xf3 doesn't seem to work. I tried 33. ♗xh4 fg+ 34. ♔g1 and wound up in a complex position in which I got, um, er, mated in the open board. <patzer2>'s 32. ♗g4 in order to answer 32. ... ef with 33. ♖xf3 might be the answer there?
Aug-29-08  arsen387: First trapping the Q, then the R. damn, it's more like a humiliation than just a win
