|Apr-25-07|| ||twin phoenix: <dzechial> tks for pointing out why black must first take the bishop on d6. unfortunately, i missed this point and tried to play 23. R-b1?? alas, missing the zwishenzugge. just another case of premature attack|
here's a real stumper how does one pronounce Ljubovic? (and i thought Alekhine would be hard to pronounce...)
|Apr-25-07|| ||outplayer: I randomly tried several moves until I saw the correct move order; 24...Rb1 25.Qxb1 f3 26.Qb8+ ( There's no black knight on the board here) Bf8(forced) and white can't parry the mate threat. If white played 20.a5 with the idea of Qa4 it is absolutely illogical to give up the b-file with 21.Rxb8?|
|Apr-25-07|| ||outplayer: It is a nice deflection.|
|Apr-25-07|| ||MaxxLange: I missed 25. Qb8+; so, I consider myself to have gotten this wrong. No donut!|
|Apr-25-07|| ||outplayer: Don't be so bad to you. I didn't even thought about it but I still think I got the puzzle right. Have some donuts! Lol.|
|Apr-25-07|| ||MostlyAverageJoe: <twin phoenix: how does one pronounce Ljubovic?>|
Why, just the way it is written. Ljubojevic :-)
OK, try "Lyuboyevitch" (assuming the appropriate diacritical above 'c').
|Apr-25-07|| ||twin phoenix: tks mostlyavejoe. LOL
|Apr-25-07|| ||Rama: loo-BO-mir la-BOY-a-vic or -vitch. Lubosh for short. Simplify, heh.|
But surely 21. Qf3 ..., or 21. Qh5 ..., is better than the Rook-exchange? That struck me instantly as it was played.
|Apr-25-07|| ||zb2cr: Oooh. Missed this one, because I saw 23. ... Rb1--but not White's resources in dealing with it.|
|Apr-25-07|| ||esticles: <outplayer: 24...Rb1 25.Qxb1 f3 26.Qb8+ ( There's no black knight on the board here) Bf8(forced) and white can't parry the mate threat.>
If you're talking about the variation without Nxd6, white doesn't have to parry the mate threat. Qxf8#. If you missed Qb8+ you missed the puzzle, as you would have been checkmated.|
|Apr-25-07|| ||gawain: Saw the ...Rb1 deflection immediately and thought I had solved it. My bad! I should have known a Wednesday puzzle had to have an extra twist. This was a good one.|
|Apr-25-07|| ||MostlyAverageJoe: <twin phoenix: tks mostlyavejoe. LOL>
Well, it could be more difficult. Something like "Brzeczyszczykiewicz". Yeah, a real last name, over 500 hits on Google. Pity - not a chess player :-)|
<realbrob: I think that for a strong GM being up a piece means winning> Of course. Bearing this in mind, I am still puzzled that white took the knight, instead of the correct move: 24. 0-1
BTW, I hope everyone realizes that the solution does NOT involve the actual move f4-f3 by the black, but only a *threat* of that move. The best way for the white to prolong the suffering is something like this:
25. Nf5 Rxd1 26. Rxd1 Qxf5
and now *white* can do f2-f3 before getting wiped out.
|Apr-25-07|| ||outplayer: <esticles>, there's no checkmate for white in the diagrammed position.|
|Apr-25-07|| ||YouRang: I saw the main idea right away, that is: (1) We want to advance the pawn to f3, but first we need to deflect the queen from defending f3. (2) We can deflect the queen with our rook i.e. ...Rb1.|
For a moment, I thought this was it, but this seemed a little to easy for a Wednesday. Shortly, I noticed that after Qxb1 and ...f3, white had some serious counterattack with Qb8+, and I wasn't sure if I could survive it.
Back to the drawing board. However, I was sure that this line had to be part of the solution.
It took me a minute or two to realize that the Qb8+ threat was satisfactorily neutralized by first playing 23...Nxd6!! This does two good things: 1. Give the king more room, and 2. Eliminates the bishop that attacks f8 (so the queen check can be blocked with ...Bf8).
So, at worst, black picks a free bishop. Great puzzle!
|Apr-25-07|| ||newton296: like whites open here and feel he would have good game if at move 20) ...F3 (not A5?) with the idea of playing g4 closing the kingside and cutting of blacks bishop from the Q. Or even 20)... Rb3 followed by doubling the rooks and tripling with the Q on the open b file and white is dominating the q side and has a near won endgame! White's 2nd and instantly fatal mistake is the dubious plan of winning the D6 pawn by playing 22) B x h3 deflecting blacks Q away form the d6 pawn but also inviting her too the perfect atacking square at h3 where she threatens both mate in 1 at G2 after blacks ...f3 and also mate in 1 after ...Rb1 so white has to give up the his Q for Rook or the pawn to stop the duel mating threats 22)...B X H3 ugggg??
Can anyone explain the reason for white's 20) A5 move? Just seems a waste of time to me!|

23 ... ???
|Apr-25-07|| ||playground player: I must be getting smarter, 'cause I nailed this one solid! Nxd6 is a killer. Saw the Rb1 deflection move right away, but didn't rise to the bait. I wonder if playing Guess-the-Move is helping me.|
|Apr-25-07|| ||fm avari viraf: Ljubomir lands a tactical blow to achieve his goal of playing f3 where mate is inevitable.|
|Apr-25-07|| ||simsan: <dzechiel> The thought process you describe was more or less identical to my own. |
I have learnt from experience that these mid-week puzzles have some more depth than the bang-bang-# or bang-bang-xQ style of monday/tuesdays.
I actually spent most of my time on seeing white's Qb8+ response to the (faulty) immediate Rb1 Qxb1 plan.
|Apr-25-07|| ||outplayer: Now I see that I just played hope chess here. 23...Rb1? is not the answer.|
|Apr-25-07|| ||aazqua: Once again, just too easy.|
|Apr-25-07|| ||Timex: umm... I'm not very good at chess, so I didn't get this one. I'm not surprised most of you guys got it.|
I'm not very good at deflection themes, and many combinations
|Apr-25-07|| ||kevin86: I saw the folly of the immediate 23...♖b1 which loses. I did,however,miss the winning (though seemingly meaningless) minor piece exchange-that chokes off whites counterthrust after 26 ♕b8+|
|Apr-25-07|| ||Skylark: I missed the minor piece exchange but saw the main threat; I had to do this in a hurry though. I'm pretty confident that OTB I would have found this as black.|
|Apr-26-07|| ||Richard Taylor: I think when I played the game over my immediate reaction would be to take on d6 but from the diagrammed position, I kind of forgot about the piece on d6. It would not be hard to find in an actual game. Any fairly strong club player should find it on a good day. |
Mind you people seem to think this is some kind of competition - it doesn't really matter how long or if either or us solves it, as long as we learn something or enjoy the problem. I avoid the more difficult ones, they take too long to solve: it is (the problem of the day) really for enjoyment and if one likes, as practice.
