|Aug-15-05|| ||OhioChessFan: La da, la da da da. Monday, Monday, how I love that day. I am hoping I can improve enough that I can find the Tuesday puzzles every time also. I'll note that while everyone talks about how easy Mondays are, a former contender for the WC didn't see it!|
|Aug-15-05|| ||awfulhangover: It took me 1/2 second to solve this. When I solve the Sunday puzzles that fast, I will join a chess club.|
|Aug-15-05|| ||Richard Taylor: <chessgames.com> it's a good chnage |
and in line with that change change is there also a possibilty for a more general "puzzle" or "puzzles" in which the move(s) is (are) not the best - as you are indeed proposing -but in which we - or anyone visiting chessgames - all try to find the correct positional move (the implication is that even if one has some good ideas and they are wrong one will learn from that or those concepts and one could get (give oneself) "points" (kudos so to speak for oneself) even for a "wrong" line if it has good ideas in it - - that is what is good about P Wells's "Piece Power" if you don't "solve" the position (frequently you dont necesarily lose or not win by choosing something other than what is played) - he gives variations and it is a good way to learn - hence there could be a tactical theme problem and a positional theme problem ["white tomove - examine thepwan strcutrue -whtis a good move to...XYZ?" etc] - for various levels (maybe mnore that one "puzzle" a day) - that said I realise that would mean a lot of organising -
the daily puzzle is very good - and the move away from a "White/Black to move and win by force or White/Black to move and win is good as that is what Chess is like in "real life" - we rarely -even the Gms rarely see all the variations - I bet they (well a lot would) keep quiet about lines they actually miss and some moves they play "instinctively" (of course they also calculate moves and sometimes eveythgn is analysed) -but cf. how once Ray Keene commenting how he made a sac -realising it was thematically the best plan - then stopped and analysed a lot of the variations...that sort of thing...
|Aug-15-05|| ||Richard Taylor: <OhioChessFan> <can improve enough that I can find the Tuesday puzzles every time also. I'll note that while everyone talks about how easy Mondays are, a former contender for the WC didn't see it!> yes he did - he saw it and then resigned! These "easy" puzzles are good for practicing as much as any other kind|
|Aug-15-05|| ||ckr: Queen sac, about 1 minute. However I feel sure that it was also in the tatics database at MyChess.com.|
|Aug-15-05|| ||Robin01: I solved this one very quick.|
|Aug-15-05|| ||sentut: what a simple question solution:35. Qxh6+ Sg8 36. Rg2+ END.|
|Aug-15-05|| ||DanRoss53: 32... c4! looks like a winning move for Black. Perhaps the game would continue 33. xf5 xf5 34. xf5 xf5 35. bxc4 xf2 36. xf2 xf2 37. b1 h5|
|Aug-15-05|| ||PARACONT1: <sentut> Actually, Qxh6+ Kg8 then Qxg7 mate is faster =P|
|Aug-15-05|| ||gerpm: I think the change is very good. Thank you for all the enjoyment you have given me and other chess palyers|
|Aug-15-05|| ||notyetagm: Here Nigel loses to an elegant <corridor mate> with 34 xh6+! gxh6 (34 ... g8 35 xg7#} 35 xh6#. The key to this mating attack: <the open g- and h- files>. Gurevich successfully sacrifices his queen to completely open these two files and then deliver mate down them using his two rooks.|
Note that 10 years later Nigel got to play the exact same mating pattern in a game against Alexander Grischuk, 32 ... xh3+!, in this game Grischuk vs Short, 2000.
|Aug-15-05|| ||sanferrera: That is an excellent note, notyetagm!
It really looks similar! Even both rooks on the same row.
|Aug-15-05|| ||notyetagm: <Sneaky: <perhaps, this would have been more amazing if the position after the 32-nd Black's move had been presented for the Monday puzzle.> But then it doesn't work. Instead of 33...Qxf5? simply 33...Rxf5 holds.>|
I have not Fritzed the game yet but that was my initial thought. Why not just re-capture with the f6-rook (33 ... xf5), leaving the Black queen on d7 for <2nd rank defense>? Then the queen sacrifice on h6 is an outright blunder because Black can simply interpose his queen on h7 to block the check from the White h6-rook: 33 xf5 xf5 34 xh6+?? gxh6 35 xh6+ h7.
|Aug-15-05|| ||notyetagm: <sanferrera: That is an excellent note, notyetagm! |
It really looks similar! Even both rooks on the same row.>
Yes, that is what jarred my memory, the adjacent 6th rank rooks, g6/h6 in this game versus g3/h3 in the Grischuk game given above.
|Aug-15-05|| ||azaris: I guess Short remembered falling into this tactical pattern when he played Short vs Jiangchuan, 2004.|
|Aug-15-05|| ||patzer2: <DanRoss53> <32... c4! looks like a winning move for Black.> Yes indeed, instead of the weak 32...Rf6?, Fritz 8 gives both 32...c4! and 32...Rb8! as winning for Black (@ 16 depth & 1213kN/s): |
M Gurevich - Short Nigel D (ENG)
5r1k/3q1rp1/p2p2Rp/2pPpn1Q/4B3/PPp1P3/5P1R/K7 b - - 0 1
Analysis by Fritz 8:
1. (-2.13): 32...c4 33.Bxf5 Qxf5 34.Qxf5 Rxf5 35.bxc4 Rxf2 36.Rxf2 Rxf2 37.Kb1 h5 38.Kc1 h4 39.c5 dxc5
2. (-1.53): 32...Rb8 33.Bc2 Rxb3 34.Bxb3 Qb5 35.Qd1 c4 36.Qe1 cxb3 37.Qxc3 Qf1+ 38.Kb2 Qe2+ 39.Kc1
Also, instead of the final blunder 33...Qxf5??, Black might have survived with 33...Rxf5 . One possibility played out to a draw by perpetual check with Fritz 8 went:
33... Rxf5 34. Rxh6+ gxh6 35. Qxh6+ Kg8 36. Rg2+ Kf7 37. Rg7+
Ke8 38. Rxd7 Kxd7 39. Qe6+ Kc7 40. Qe7+ Kc8 41. Qxd6 R8f6 42. Qxc5+ Kd7 43. f4 exf4 44. e4 Rh5 45. Qa7+ Ke8 46. e5 Rh1+ 47. Ka2 Rfh6 48. Qb8+ Ke7 49. Qc7+ Kf8 50. b4 R6h2+ 51. Kb3 c2 52. Qd8+ Kg7 53. Qe7+ Kg8 54. Qe6+ Kg7 55. Qg4+ Kh8 56. Qc8+ = (0.00 @ 20 depth).
In any event, the final 34. Qxh6+!, and today's puzzle solution, is an instructive illustration for novices (and for stronger players trying to avoid blunders) of how easily the Queen can be used as a sacrifice (i.e. pseudo or sham sacrifice) for a quick deflection mate.
|Aug-15-05|| ||notyetagm: <azaris: I guess Short remembered falling into this tactical pattern when he played Short vs Jiangchuan, 2004.>|
Different pattern. The game versus Jiangchuan is trapping the king on the h-file with one rook, the g-file being inaccessible to the enemy king. The pattern here and in the Grischuk game is using <both> of your rooks to trap the enemy king on the open g- and h- files.
|Aug-15-05|| ||EmperorAtahualpa: a nice puzzle for Mondays|
|Aug-15-05|| ||sfm: In an important game Najdorf once played with two rooks left against two knights and two passed pawns. He managed to sacrifice the rooks for the pawns and his opponent sat back with only two knights. "Everyone knows" that this is a draw - so Najdorf was puzzled when his opponent wanted to play on. Najdorf commented and his opponent (I have forgotten who) looked up and said: "Don't you know??? An unknown player in Baku demonstrated a win last month, overlooked for hundreds of years!" He looked down again, speculatively, then made a move with a knight. Najdorf went (so the story goes) "pale as a corpse" - then his opponent sat back and laughed. "Just joking! Draw!"|
OK, hasn't much to do with this game, but it has something to do with Gurevich - there's one "Noteworthy game". Here he as Black ends up with only 2 knights. White's king is in the center, but unfortunately there is also two white pawns left. Then White, king still in the center, gets rid of one of them...
(To be continued..)
If the suspense is too much, go and see the very interesting game yourself.
|Aug-15-05|| ||alexandrovm: I think if the queen takes h6, it wins the game very fast. If black retakes, Rh2xh6 wins on the spot. If black just plays Kg8, it's just mate in one|
|Aug-15-05|| ||Sneaky: <The implied challenge is to find the best move, whether it wins, draws, or leaves things unclear.> I love it!! One question, what do you mean 'leaves things unclear'?? |
"Black to play, and muddy-up the position."
|Aug-15-05|| ||Nick816: Are the monday puzzles supposed to be easy because there wasn't much to calcaute or work out here|
Qxh6 and then Kg8 or gxh6 were black's only options so it wasn't that hard to visualize
I've just started trying to solve these on a daily basis so I am new to how they select them
|Aug-15-05|| ||vinohradska: Yes, "White to play" seems better to me. You can link from that statement to a FAQ entry to explain that "to play" might mean "to force a mate" or only "to gain a winnable lead". You might also want to mention there that the puzzles start off easy on Monday...|
|Aug-15-05|| ||jahhaj: <Nick816> Monday's are easiest, they get harder during the week. You are doing very well if you get a Sunday puzzle.|
If you are a premium member then you can review past puzzles in the <tactics archive>.
|Aug-15-05|| ||Nick816: oh ok
thanks for the info
eh I've done ok on the Sunday puzzles
I usually get the first couple moves or main idea but don't figure out all the varitations
never really tried to sit down and work everything out though..just a glance
