|Jul-05-04|| ||samvega: The idea 15.Bxg7 looks dubious. Did Morozevich originally intend to follow up with 17.Qxh7, and then reconsider?|
Anyway, white is obliged to part with the exchange. Then black furthers his material advantage with some nice tactics:
28..Nb5! (evacuation; forking; skewer)
31..Nc3! (interference, back rank)
|Jul-15-04|| ||chessfected: Patzer2, you mean
31...Nc3 32. bc Bd3+ 33. Be2 (forced otherwise 33...Re1+ follows) Rxe2 and there's no answer to the double threat of 34...Re1 mate or 34...Rb2+ netting the rook
|Jul-15-04|| ||waltonway: Nice blocking move on white's rook. No way to counter the mate threat without falling behind in material. |
|Jul-15-04|| ||patzer2: After the 31...Nc3! solution and the 32. g4 Bxg4 followup in today's puzzle, White resigns because of the threat of 33. bxc3 Bh3+! 34. Kg1 Re1+ 35. Nxe1 Rxe1#.|
Sorry <chessfected> if my initial post, leaving out a key couple of moves, was confusing. This is the corrected post.
|Jul-15-04|| ||midknightblue: Hi. Havent seen the answer yet. Just here to say this looks extremely difficult. Be back when I give up, or solve it. |
|Jul-15-04|| ||Benzol: I actually got this one. |
|Jul-15-04|| ||Sneaky: I think I see a theme developing. The back-rank mate which depends on the intermezzo check to make it work. |
|Jul-15-04|| ||midknightblue: Got it, Nc3! yes!!. White is hopeless from there. As noted by chessfected, white cant do 32 bxc3 cuz mate follows. Instead black moves a pawn (32 g4) to attempt to remove the back rank weakness. But the back rank weakness persists as noted in patzer2's line above. Great puzzle. |
|Jul-15-04|| ||rover: I actually messed this up. I saw Nc3 but completely ignored g4. I just saw that bxc3 fails to Bd3+ |
|Jul-15-04|| ||Chesspatch: What are you talking about? g4 still loses. |
|Jul-15-04|| ||karlzen: Moro must've had a really bad day, 17.Bh6?? loses the exchange and the game. Perhaps he had read the whole line in the Informant, mixing up 'Q' for 'B'. :) The endgame after 17.Be5 is admittedly very bad for white, much suffering there. 17.Qxh7 looks very dangerous but should be played, black at least has to prove something. It is what the Russians call, "the principle variation". 17.Qh6 followed by Bxh7 is another possibility, there black can try Rxg7!? (on Bxh7) or just allowing Bxg8 Rxg8 with a good attack.|
This variation (with Nc6 and Bxg7) has been played a few times on GM level I believe. The other variation goes 14...Ng6 15.Bxg7 Rg8 16.Bxg6 Rxg7 17.Rxe6 hxg6 with interesting play. I think 11...Bg4 is the way to go if black doesn't want these messy positions.
|Jul-15-04|| ||Hinchliffe: <Karlzen> As it is my birthday today I am going to regard your comments as a birthday gift. As usual you have made some excellent observations and although 11...Bg4 leads to some serious wood chopping it probably represents a comparatively even way to proceed. Thanks Karlzen hope Gothenburg is experiencing good weather. |
|Jul-15-04|| ||themindset: although i know that Bxg7 is "theory" i agree with the assessment that it is somewhat dubious. why trade a center pawn for a pawn that opens a file directly onto your king?|
it seems that it puts you in a position where the slightest blunder could cost you the game (as we've seen).
|Jul-15-04|| ||ruylopez900: Hmm, missed out on it today. I was looking at playing ...d3 trying to pull the Knight away or, once it was on d2 having a protected Rook deliver back rank mate. Oh well. |
|Jul-15-04|| ||Everett: These interference puzzles are great. Really gets one thinking about how the pieces work together in a more subtle fashion than typical pins and such. |
|Jul-15-04|| ||tamar: The unlikely knight tour ♘c6-♘d4-♘b5!-♘c3!! is worth studying in detail. 28...Nb5 29 axb5 d4 30 Bxd4 Rxd4
is simpler than I thought. Or 30 Bb3 Rxe3! Everything works. |
|Jul-15-04|| ||Calchexas: What!? Uh, sorry, even after I saw this one, I had to stare at it for 5 minutes before I got how it worked. That's just insane. |
|Jul-15-04|| ||karlzen: <Hinchliffe>, Happy Birthday! Thank you for your very kind words but unfortunately the weather is as it "always is", cloudy. I comfort myself with the fact that we have the Swedish Championships here in Gothenburg now (perhaps you will be competing in the second week or next year?). An old rival of mine amazingly shares the lead, somehow. |
|Jul-15-04|| ||patzer2: Notice the key role the White pawn on h2 plays in this combination. If the White pawn on h2 were not there, then 31...Nc3 32. g4 Bxg4 33. bxc3 Bh3+! 34. Kg1 Re1+ 35. Nxe1 Rxe1+ 36. Kh2 would leave White with the winning position (leaving an escape square to avoid the back rank mate).|
It is often useful in analyzing combinations to examine slight differences in pawn and piece placement to see what makes a particular combiantion work or not work. Novices and club players often think they recognize a winning tactical pattern, and as a result often move too quickly to make enticing but entirely unworkable tactical forays (strong experts and masters often set traps to encourage such mistakes). I have personally found that getting in the practice of analyzing combinations for these subtle differences is helpful in avoiding such tactical errors.
|Jul-15-04|| ||kevin86: This one has the look of a real chess problem-with a nice theme change in the middle.|
Black desired to chase the king from f1 to g1 so he could mate at e1. White attempted to escape-so the check added an additional component of stopping the escape AND chasing the king!!
|Jul-15-04|| ||bob725: I got this one as well!!!
That makes Mon-Thurs.4/4
|Jul-15-04|| ||notyetagm: Well, I got the 31 ... Nc3! part but missed the most effective white response of 32 g4. But partial credit is not bad for a position that Moro missed. |
|Jul-15-04|| ||Sneaky: <what is the continuation if white plays 33. Kg2?> ...Nxd1 and Black helps himself to a free bishop. |
|Jul-15-04|| ||ezumpf: I actually got tadays puzzle. I am curious about the best continuation after 33.Kg2. Hope that's not too dumb a question. Thanks. |
|Jul-15-04|| ||ezumpf: I saw the free bishop Sneaky, thanks. I was just curious if there were any impending mates I am not seeing. Thanks again. |
