|Jul-17-05|| ||jorgegatica: Here Spassky demonstrate clearly that he deserved to be the previous World Chess Champion.
The combination shows an accurate execution.
|Jul-17-05|| ||crafty: 20...cxb2+ 21. xb2 xc2+ 22. a3 g6 23. xd8+ h7 24. h8+ (eval 8.51; depth 14 ply; 500M nodes)|
|Jul-17-05|| ||Hektor: You could see Spassky drop the gauntlet back on 15. e5. Black's options are extremely limited here since 15...Nd7 or 15...Ne8 are both very passive and leave him with no defenders on the right half of the board. From this perspective it seems as though 14...d5 was a losing move in an already uncomfortable position. I wonder how much better 14...b6 or 14...b5 would be.|
|Jul-17-05|| ||black knight c6: nicely thought out sac.|
|Jul-17-05|| ||Counterpoint: The key move here is 20.Qg5! forcing black to play checking moves and having the white queen guard over the 5th rank, in case of the black queen's threats.|
|Jul-17-05|| ||misguidedaggression: please tell me that was not the sunday puzzle! I got it instantly. Ok, I admit that I only saw up to move 21, but then again, I have had a few drinks. I'll admit 23...Qg6 is a difficult defensive resource to meet. This position was just screaming: "Greek Gift" and it was hard to even consider any move other than Bxh7+.|
|Jul-17-05|| ||Woodpusher: Don't feel bad misguided, I didn't get it either...|
|Jul-17-05|| ||Eatman: I should have spent more time on the puzzle than I did. What I missed was that cxb2+ is not really that strong a threat. So I kept looking for ways to defend c2 after Bxh7 sac.|
|Jul-17-05|| ||FinKing: <Hektor> I think that 14...d5 was a good move because he is following a general rule: <the best reply to an attack on the wing is a counterattack to the center> and if he does not make move 14...d5 white plays maybe 15.f5 followed by h4 and black is lost. Besides, black´s queenside attack has no future. however, the <real> losing move was 15.d4.|
|Jul-17-05|| ||Richard Taylor: Isaw the guts of this - I went for 18. bh7+ K:h7 19. Qh4+ Kg8 20. Qg5 c:b2+ 21. K:b2 Q:c2+ 22. Ka3
when 22. ... Q:a2+ 23. K:b4 a5+ 24. Kc3 when I saw White was winnng after g6 25. Qh6 |
Als 23. .... Qg6 I thought lost to 24 R:d8+
I didnt see the game continuation of
20. ..Rd1+ so I back tracked and tried to work it all out again and saw everything!! (I thought) This was quite hard - and I tried to solve it too quickly - I have a feeling I have seen this combination before though - I just looked at the postion and my line was
As played until 24. Kh7 then 25. Rh8+ K:h8 25. Q:g3 f:g3 26. f7 but I see now I miscalulated and Black has Bd7!! - curses!! - infinite green boiling curmugeons, dudgeons, dungeons and toads from thick greasy soup begrungeous cruds and floating schloggs; I hurl in anger and eternal contempt toward chessgames.com and eveyrone else ! ...achhh!!!
Spassky was ovbiously a slightly better player than me! Well he probably spent an hour and 20 minutes checking out all the variations - I only spent about 15 minutes. After all, it wasn't my game ...
|Jul-17-05|| ||latebishop: Just for completeness. On 18...Kf8 White has the nice finish 19.Qc5+ Qxc5 20.Rxd8 ++|
|Jul-17-05|| ||Koster: If 14...d5 was wrong, as is likely, than 13...Rd8 is probably also not best and he should play 13...b5 to get some counterattack going. 14. g4 b4 15. g5 Nd7, then white has to decide between Na4, which is a little out of play but holds up black's a pawn, or Ne2. looks like typical Sicilian play with only very slight edge for white.|
The combination I saw right away but missed fg7! from the initial position. That's why I'll never be a great player or even a really good one. Still it seems black could have defended better. What if instead of 17...Nb4 just gf6, getting rid of that dangerous pawn? The bishop sac is still very dangerous but I'm not sure if it wins. Some lines do but others look like perpetual check.
|Jul-17-05|| ||Richard Taylor: <latebishop> I saw that instantly you said 18. ... Kf8 - was trying to get that in some variations previously -very good -brilliant! -it's a great combo inside the bigger one! Well spotted..|
|Jul-17-05|| ||patzer2: Sometimes it helps to think of a long combination as a series of shorter combinations working together, and then solve them in reverse order (from the end to the beginning of the combination). In this case, after 18. Bxh7+!, I see three mini- combinations:|
1. The final part of the combination is the deflection sequence 24. Rd8+! Kh7 25. Qh4+! Qh6 26. fxg7 which forces the win of the Queen via a removing-the guard tactic which follows! Note if Black now plays 26...Qxh4, then 27. g8=Q+ Kh6 28. Qh8+ Kg6 29. Rg8+ also wins the Queen.
2. The middle part or sequence, from 21. Rxd1 through 23. Ka3, serves two purposes for White. First, it defends to neutralize Black's counterattack. Second, it prepares the ending combination described above after Black's best defensive try 23...Qg6. It is important here to visualize that Black does not have a mating attack or a defense to parry White's attack.
3. The first part of the combination sets up a mating threat to force Black's desperate measures described in the two above sequences. In particular, after 18. Bxh7+ Kxh7 19. Qh4+ Kg8 20. Qg5! White needs to visualize that a mate threat is established, and that Black must take desperate measures to prevent it -- before proceeding to part two of the combination to ensure Black doesn't have an adequate defense.
|Jul-17-05|| ||thesonicvision: the only difficulty was calculating
black's counterattack; eyeing black's
weaknesses, noticing the bishop sac,
and the clever Qg6 can all be
figured out rather quickly.
|Jul-17-05|| ||Shokwave: Pretty easy for a Sunday puzzle. Bxh7+ just screams "play me!".|
|Jul-17-05|| ||farrooj: well yeah, but the next moves are a little hard to spot|
|Jul-17-05|| ||Calli: Sorry, no credit for just guessing Bxh7+ if you didn't see Qc2-Qg6 and win that follows. I note that in the game Spassky was so focused on mate at g7 that in the end he plays 31.g5 threatening Nf6+ Nxf6 gxf6 and mate at g7. He ignores the simpler 31.Ng5 and mate at f7. Or maybe he just wanted to mate with Q+P.|
|Jul-17-05|| ||snowie1: Interesting is 20 fxg7! If Kxg7, Qg5
+ with Rxd8 following...without spite
checks from black and the game is over
|Jul-17-05|| ||betamax: I saw the same, 20. fxg7, and I can't find any response for black that doesn't gas a queen or worse. If the black queen's bishop wasn't so useless then there might not be twenty thousand winning lines for white, but it is, and there are.|
|Jul-17-05|| ||Gowe: I don't know, 20.fxg7 is pretty complicated. Crafty could you analize that move and bring some light here?|
|Jul-17-05|| ||kevin86: Can we say-a duffer sees one move ahead,a master eleven,and a computer 111? My bias:this is a computer site,right?----see my gotd note,please.|
|Jul-17-05|| ||Richard Taylor: <Calli> even if one didn't calculate all the lines here and saw B:h7+ that is pretty good - you cant say "no credit" -no credit if you are over 2000 maybe or a GM |
I myself didn't see the line where Back plays Rd1+ and then the Q goes back to g6 -although I only looked for a few minutes - I saw about 7 or 8 moves checking that after the Qc2+ - white could escape from any attack so Qxa2+ was not possible -
So de facto I give myself credit -no credit perhaps depending on your criteria - what say you (one) have (has) only been playing chess for a year or so? Or you love chess but arent very good - probably describes most of us on here...but who cares? Even to see any of the ideas is something -of course no matter how much I study these combos etc I stil play some atrocious games of Chess...and some quite good ones - for me and many here it is a hobby - fascinating -but we are not worrying about how much credit we are giving ourselves.
Be different if there was some competition with a cash prize for the quickest solver - I would have worked this out very fast and completely! But hundreds would be there before me... (Given of course that it was possible to know everyone taking part were not "cheating" - with a computer or moving the pieces around etc) -but then all those egg head people - like Shirov who can solve 31 move problems in 10 minutes without chess board actually in front of him - would be furiously solving Chessgames.com's problems.
Most duffers and patzers like myself are happy to "solve" or to "get" some of the main ideas in some of these and sometimes solved me completely - I have rarely completely "solved" any of these -some I got most of...
|Jul-17-05|| ||chessgames.com: <20. fxg7> only draws the game--that's one of the reasons why this was selected for Sunday. We'll let Crafty provide the details.|
|Jul-17-05|| ||crafty: 20. fxg7 xd1+ 21. xd1 cxb2+ 22. xb2 xc2+ 23. a3 (eval 0.83; depth 9 ply; 25M nodes)|
