|Sep-23-08|| ||Once: <YetAnotherAmateur> Fritz 11 agrees with you. 24. ... Qe4 is evaluated as over +4, but 24. ... Qxd1 is just +0.32.|
But I think that black's main mistake comes earlier - a passive opening allows white's tactic around moves 17-22 which rams the bishop into f6.
|Sep-23-08|| ||JG27Pyth: <Aagb2002 <VooDooMoves: <Soinne> 25...h5 does indeed look better but I wonder how black would play after 26. Qg4! This pins the g-pawn threatening 27. Rxh5 and 28. Rh8#. If|
C) 26...Qc4 27. Rg1 (Rxh5?? Qxf1#!) Nd5 28. Rxh5 Nxf6 29. exf6 Qc2 30. Rh6 Qe2 and black escapes.> How about 30.Rh8+ Kxh8 31.Qh4+ Kg8 32.Qh6 ?>
I don't understand 29...Qc2 why not 29...Qe2 and now if 30.Rh8+?? Kxh8 31. Qh4+ Qh5
Which suggests 27.Re1 as a possible improvement (guarding e2) but it fails as it self-pins the e pawn preventing the 29.exf6 recapture.
I think this line 25...h5 26 Qg4!? Qc4 27.Rg1 Nd5 28. Rxh5 Nxf6 29.exf6 Qe2 holds for black.
|Sep-23-08|| ||playground player: The solution to this puzzle illustrates issues raised a few days ago by <dghins> and others, who complained that they weren't learning anything from these puzzles.|
But I was able to solve this one because I have learned to see certain checkmate patterns. Here, it's obvious that if we can get our h-Rook to h8, the Black King is toast. But first we have to take the Black pawn on h6; and if we try to do that first, Black's Knight takes our Bishop and the checkmate threat evaporates.
So the key is the Black Knight, which our Queen can take. And once he's out of the picture, then we can play Rxh6, and there's no way Black can stave off mate.
These puzzles do teach: but we have to know how to learn from them.
|Sep-23-08|| ||charms: Eduardo Patricio Iturrizaga Bonelli - how do you call that guy if you're short on time?|
|Sep-23-08|| ||kevin86: I missed this one due to "piece blindness". I thought that after 26 ♖xh6 ♘xf6 27 exf6-that white would threaten mate-oops,I had a rook and not a queen.|
I tried a queen sac but it was doomed to failure 26 ♕h5?? gxh7 27 ♖g3+ ♕g6! wins 4 black.
I had a bad day today-as Brett Favre did last night.
|Sep-23-08|| ||tatarch: The f6 bishop is just ruthless in these positions. White's whole combination from move 16 to move 22, which puts his dark bishop in that spot, is very instructive.|
I gave a quick thought to 25...Kh7 for black, but that loses quickly to Rxh6+ followed by Rf3.
|Sep-23-08|| ||chopbox: <JG27Pyth: I think this line 25...h5 26 Qg4!? Qc4 27.Rg1 Nd5 28. Rxh5 Nxf6 29.exf6 Qe2 holds for black.>|
Best comment of the day! Thank you.
|Sep-23-08|| ||Kasputin: <whiteshark: <26.Qxd5> and if <26...Qe2> then <27.Rg1 h5 28.Rg3> (threat is 29.Rxg6+)>|
Another interesting idea involving ...Qe2. I have a feeling that you are right in your assessment of shifting the white rooks around like this. After 28. Rg3 black could try ...Kf8 or ...Rad8. White could well have some very strong replies to either (I haven't tried to calculate it all out), but I still might just play 27. Qf3 in response to 26 ...Qe2. The reason (for me anyway) is that it is just a lot easier to see a safe and easy route to the win.
As I posted earlier, this forces the exchange of queens: 27 ...Qxf3. Then I think that I would play 28. Rhxf3. The idea is simply to double the rooks on the d-file, then play Rd8. I think that white can force the trade of all rooks (it is hard to see how black can avoid this without further comprising the position). With the rooks gone, then it is almost autopilot as far as white is concerned. Sure, this takes a lot longer (assuming that black continues to play), but it is a safe alternative way to play.
|Sep-23-08|| ||bengalcat47: This puzzle reminds me of Blackburne's famous win against Schwarz at Berlin in 1881. In this game you have the same theme, with the White queen and a rook sacrificed to bring about the unavoidable mate at h8.|
|Sep-23-08|| ||TheaN: <Kasputin> I like <26.Qxd5 Qe2 27.Qf3 Qxf3 28.Rfxf3>:|
28....Kh7?? 29.Rxh6† Kxh6 30.Rh3‡
28....h5 29.g4 : White both guards the potential back rank mate and demolishes Black's kingside. I believe this is one of the most solid and crushing continuations are 26....Qe2.
|Sep-23-08|| ||Kasputin: <TheaN> More than one way to skin a cat. My method is to put out some yummy kitty food (containing tranquilizer), wait for puss to gobble that up (maybe have a smoke or a beer in the meantime) and generally take my time. Your method is to put on some oven mitts (i.e., trade queens), then go for kitty with the big steak knife. Very nice. I think I prefer your method actually.|
|Sep-23-08|| ||TheaN: I'd like to repost this: <Join the Chess Puzzle League!> Everybody, please look at my profile if you like another challenge of chesspuzzles, weekly!|
Might be an ad but I'd like to get some people to join in ^^.
|Sep-23-08|| ||TheaN: <Kasputin> o.O... I think that I'm not gonna let my cat near you: but you made your point.|
|Sep-23-08|| ||chrisowen: thanks <patzer2> it seems you are right on track. I have to note that 25..h5 26 f5! Nd5 27. Rh4 Qxg2 is not any good either leaving white virtually a piece ahead. In your line 32.Rg5 duffs up the black king by signalling mate.|
|Sep-23-08|| ||stacase: Regarding the "I got this because it's a puzzle" and would "Miss it over the board" idea: |
I think a decent player would see the move the Rook would like to make and start looking for ways to get rid of the pesky Knight.
The "What happens if I blow away the Knight with the Queen?" move would be a consideration. "Hmmmm let's check that one out" would be my response.
Then like I said before, "BANG!"
|Sep-23-08|| ||VooDooMoves: <JG27Pyth> <I think this line 25...h5 26. Qg4!? Qc4 27. Rg1 Nd5 28. Rxh5 Nxf6 29. exf6 Qe2 holds for black> Agreed, my 26. Qg4 didn't work initially but how about this line:|
1) 25...h5 26. Qg4!? <my idea so I have to fight for her ;)> 26...Qc4 27. Rg1 Nd5 28. Qg5! and now
a)28...Qxf4 29. Rxh5! Qxg5 Rh8#
b)28...Qxf4 29. Rxh5 Nxf6 30. Qxf4 Nxh5
c)28... Nxf6 29. exf6 Qe6 (whites threat is now queen to h6 and g7# and 29...Kh7? 30. Rxh7+ Kg8 31. Qh6 allows white to continue with said plans) 30. Rxh5 Qf5 31. Rh8+! (now this works) Kxh8 (forced) 32. Qh6+ Kg8 33. Qg7 # :D
|Sep-23-08|| ||Formula7: At first I thought the solution might be 26.Qh5??, but then I saw gxh5 27.Rg3+ Qg6! and black wins.|
A few seconds later I noticed 26.Qxd5! and if 26..Qxd5?? then Rxh6 and the only way for black to prevent mate is Qxg2+ and after 28.Kxg2 then mate is unstoppable.
|Sep-23-08|| ||Soinne: <VooDooMoves> Indeed, after 26. Qg4! the end is near for black. Clever...|
|Sep-23-08|| ||VooDooMoves: <Soinne> <Clever...> Thanks :)|
|Sep-23-08|| ||JG27Pyth: Voodoo:< c)28... Nxf6 29. exf6 Qe6 (whites threat is now queen to h6 and g7# and 29...Kh7? 30. Rxh7+ Kg8 31. Qh6 allows white to continue with said plans) 30. Rxh5 Qf5 31. Rh8+! (now this works) Kxh8 (forced) 32. Qh6+ Kg8 33. Qg7 # :D> |
Very impressive... Black's takes line b and plays on to try to swindle a draw IMO.
But back up, I think we missed something interesting:
...h5 26.Qg4 Qc4 27.Rg1 Nd3! (threatening Nf2#... and it's not an empty threat. I'm probably missing something basic in one of the lines below, but it looks to me like the N causes some problems for white... it prevents Qg5 for the moment, too.)
A few variations after ...Nd3
28.g3?? Nf2+ Kg2 Nxg3
28.Rg1 Nf2+ Rxf2?? Qc1+
28.Rg1 Nf2+ 30.Kg1 Nxh3+ 31.gxh3 Re6... to sac back the exchange on f6 with drawing chances.
28.Qg3 Nxf4 29.Qg5 Nxh3 (threatening Nf2# again) 30.gxh3 Qe4+ 1/2-1/2
|Sep-23-08|| ||VooDooMoves: <JG27Pyth> 27...Nd3! is a great move! <Active defense>. I was only looking for ways black could stop mate threats but never imagined black could produce his own. Think I found an improvement to 1 of your lines though:|
25...h5 26. Qg4 (I'm determined to make this work, LOL) Qc4 27. Rg1 Nd3! 28. Qg3 Nxf4 29. Rh4< pinning> Ne2 30. Qg5! and it seems here there is no stopping white.
a)30...Kh7 31. Rxh5+ gxh5 ( 31...Kg8 32. Rh8#) 32. Qg7#
b)30...Qxh4 31. Qxh4. At first I thought I could play (31. Qh6 and after 31...Qxf6 32. gxf6 mate cannot be stopped on g7 but black has 31...Ng3 Mate!
c)30...Nxg1 31. Qh6 is hopeless.
|Sep-23-08|| ||I Offer You A Resign: Today was relatively easy.
First, you had to notice:
1.) If you can clear out the h file for your rook, ♖h8 is mate.
2.) If you are hasty with ♖xh6, you don't get much after ♘xf6.
So, the answer is...
Black can only respond by either...
♕xd5, but that instantly loses because of ♖xh6, forcing ♖h8#.
♕e2, threatening mate by ♕xf1, but after ♖g1, Black is down a piece.
|Sep-23-08|| ||sataranj: 26.Qxd5! and black at least loses the queen. phew|
|Sep-23-08|| ||JG27Pyth: Voodoo: I could just feel that there was a refutation there I was overlooking, and Rh4 appears to be it. Well done. You have defended your lady's honor -- Qg4! is indeed a brilliancy. |
Which bring us back to your line b) which leaves white up -- Q vs R and N...
Great analysis -- it's amazing what you can find in some positions when you dig.
Now I've got to plug this position into the silcon and see how we compare.
|Sep-23-08|| ||VooDooMoves: <JG27Pyth> It is amazing what you can find when you dig. The position seemed so simple but it was anything but. Thanks for the back-and-forth analysis, it was testing and that's what I find fascinating about chess: the complexity.|
