| Sep-17-11 | | Creg: Attack!! --- But which move order? 22...Rxe3 or 22...Bxh3 22...Bxh3 23.gxh3 Qxh3+ 24.Ke2 Rxe3+
A) 25.fxe3 Qg2+ white loses his queen on b2
B) 25.Kxe3 Re8+ 26.Kd2 Qxf3 and it looks to me that black has decent prospects for the exchange. It may even be better to play 26...Bf4+ first. B1) 26...Bf4+ 27.Kc2 (if 27.Kd1 or Kc3 then 27...Qxf3+ followed by 28...Re2+) 27...Re2+ 28.Nd2 Rxd2+ and the white queen falls. ---
Of course I never spent one moment on white not accepting the sacrifice....grrr |

 | | Honza Cervenka: This one was quite simple for Saturday. 22...Bxh3 is the key shot, which simply wins a Pawn as the Bishop cannot be captured. I did not calculate the continuation 23.Nxc6 beyond Rxc6 24.Ne5 Bxe5 because it was not necessary for assessment of the position as much better and technically won for black. I think that if you were able to see why the Bishop on h3 cannot be taken, you have solved the puzzle. Of course, Tseitlin's execution of the finish was very powerful, though I guess that white could prolong his resistance by picking another defense than that one in the text. |

| Sep-17-11 | | Zan: <scholes: Is there some other good chess puzzles site. Chessgames.com problems are very nice but its pity that previous puzzles are not available to free members.>
chesstempo.com is pretty good. free members can do two endgame puzzles per day and unlimited tactics based puzzles selected at random. The paying members don't have the limit on endgame puzzles, can do more sophisticated searches to practice certain tactics, can view the game the puzzle came from, and see multiple alternate lines. It doesn't have puzzles of the day so you won't get conversations on puzzles as much as you do here, but it has a large puzzle collection. |

| Sep-17-11 | | morfishine: In the puzzle position black to move <22...> white has over-committed his forces to the Q-side while black has overwhelming force aimed at the white king. Also, to further black's attack, his king-rook greedily eyes the juicy square <e4>. While White may have thought his <Nf3> & <Be3> were adequate defense, his Queen is needed to cover those squares too; for example from either <c3> or <e2>. With the White Queen not covering these critical squares, black can launch a sacrificial attack starting with <22...Bxh3> After 23.gxh3 Qxh3 24.Qe2 Re4 (with the awful threat 25...Rg4+)

There is no real adequate defense here: 25.Ne5 Nxe5 26.f3 (To stop Rg4+)...Nxf3+ 27.Kf2 Qg3+ 28.Kf1 Qh3+ 29.Kf2 Bg3+ 30.Kxf3 Be1 mate:

White must find something better than 23.gxh3 or 24.Qe2; First, if white declines the bishop with <23.Nxc6> black continues the attack with 23...Rxc6 (threatening 24...Rg6)
If now 24.Qe2 (24.gxh3 Qxh3 is even stronger than the first example as both black rooks are now active)...Qg4 25.Qf1 (25.g3 fails to 25...Bxg3+ 26.fxg3 Qxg3+ 27.Kh1 Rxe3 28.Rg1 Qxf3+ 29.Qxf3 Rxf3 and Black is a piece up with a winning position)...Rg6! (piling up on <g2>) If now 26.Ne1 (what else? 26.Ne5 Bxe5 26.dxe5 Rxe5 threatening 27...Bxg2 28.Qxg2 Qe6 pinning the white queen)...Black finishes with 26...Bxg2!
(If 27.Qxg2 then 27...Qh3 and again whites queen is pinned). So, 27.Nxg2 Qh3! Here, white must resign: If 28.Queen moves Qxg2 mate; and if 28.f3 or f4 to give the King 'luft', then 28...Rxe3 with an overwhelming position:

White is helpless: the dual threat Rxf3 & Qh2+ leaves him without resource. Conclusion: 22...Bxh3 and black wins |

| Sep-17-11 | | sevenseaman: <morfishine> Nice to see ya shredding'em. |
|
| Sep-17-11 | | morfishine: <sevenseaman> Oops! I set it up wrong with the king on <g1>. I thought I got over that problem. Oh, well, it was still a good exercise. I'd actually be upset over such a silly oversight if I wasn't having so much fun! Good for you, you ripped it apart at the seams! At least I got <23.Nxc6> as some small consolation for having set up the board wrong. Oh well, on to Sunday! (and we'll ensure a correct board!) |
|
| Sep-17-11 | | chesssantosh: <sevenseaman> can you please leave your email on my forum?i am willing to ask you few questions.thanks in advance |
|
| Sep-17-11 | | sevenseaman: How do you re-set up the board? I thought it comes already set up on the 'home page'. You mean you set up the puzzle on wooden board? Only in that case can an error creep in. It does not matter though, still well done. Its your vigorous attitude that I like. |

 | | kevin86: I just took a stab at this one:I saw the possible sacs at e3 and h3;the latter looked better. The actual play was brilliant. |

 | | Jimfromprovidence: I kind of liked the ending to this one because black could still go wrong. For example, with 26...Qg4+? (instead of the correct 26...Rg6+) white can escape safely with 27 Kf1.
click for larger view I also liked 28...Qd3, as it closes off all escape squares for the king. If white gets cute with 29 f3, (to block the rook check at g1) black simply plays 29...Qxe3+.

| Sep-17-11 | | BOSTER: White king's side weaken by moving h2-h3. This pawn now is the target for attack. White queen on b2 unprotected, which gives a big advantage for black if they put his queen on the second rank after f2 and g2 disappeared. Black has opened "e" file, two bishops and all pieces are protected.
So 22...Bxh3, if white are greedy,they will take the bishop and lost very fast.
23.gxh3 Qxh3+ 24.Ke2 Rxe3+ if 25.fxe3 Qg2 and Qxb2 25.Kxe3 Re8+ 26.Kd2 Qxf3 and black win. If white not so careful with <material> they can play like this
22...Bxh3 23.Nxc6 Rxc6 24.Ne1 or 23.Ne1 and they can continue to play. <scholes> <CG.com problems are very nice but it is pity that previous puzzles are not available to free members>.
This is not correct. Open any regular Kibitzer's games (for ex. <dzechiel>) and you can find all previous puzzles. |

| Sep-17-11 | | porkfloyd: In positions like these you really shouldn't calculate possibilities like Ng1 OTB. Its just a waste of time, you win a pawn and white is just trying to hold on. You can calculate that later if white actually plays that move. Once you figure out that Bxh3 is a playable (and indeed, good) move then all you should be doing is making sure that there is not anything stronger, then make your move and hit the clock. |

 | | chrisowen: am in gre gorian mood chew the cud Geller Na5 sets tone I found bxh3 shop long but balls'd rest bxg2! a a gentle touch then boom <27qb5> ar caught in throat en down <Once> up in smoke again still rambling as ever. i had the good fortune to once play cricket in it is your part of the woods. again I remember practising in the nets my first balls went sailing over the top until i got on the brew and that calmed me down main castle like ground very picturesque. |
|
| Sep-17-11 | | Memethecat: <once> thanks for your help and advice. i understand the thinking from a game point of veiw, play <22...Bxh3> because its the right move. but from the point of veiw of a puzzle like this one, you can still play the right move but then you look for the oppositions best reply, if his best reply cuts your plan to pieces then what? look for other replys that will allow you to progress? and continue like this until you have won. the possibilities seem endless, and after making up some bad replys for white i start to doubt my first move and the line im on. I dont think i've got the brain power to deal with that amount of if's. I can solve weekend puzzles but only when there's a strong thread of move counter move. |

 | | LIFE Master AJ: Hmmm, complete turn-around from the other day.
After doing the checklist, I quickly identified a few candidate moves, and within a short amount of time, 22...BxP/h3; moved to the top of my list. I DID take about 10-15 minutes ... and check my calculations, there were more than a few lines ... with a number of branches. |

| | LIFE Master AJ: <<<once> Black has stuck his hands down white's trousers and got away with it.>> That sounded almost vulgar, but I think I know what you meant! |

Sep-17-11
| | LIFE Master AJ: <Once> actually makes a VERY valid point! And this is something I have been preaching on for a while now. There is a HUGE difference in how machines play chess and how humans do it. In a lost position, the machine will midlessly play "give-away," a human will at least be going for a stalemate ... usually before throwing his Queen away for little or no compensation, the human player will resign. After 22...BxP/h3; moves that don't challenge my idea don't worry me too much; in a tournament, I know I have won a valuable Pawn and will probably triumph in the endgame! |
|
| Sep-17-11 | | morfishine: <sevenseaman> On <How do you re-set up the board?> I use both. No matter, I'm not worried in the least about it. I am mildly curious since I referred back to the home page, oh, about a dozen times while I was trying to save white. Must've been the blinders creeping in again. I really would've liked to worked the problem from the correct position, but 'se las vie, mona mi' (pretty horrible french, no?) :) |
|
Sep-17-11
| | LIFE Master AJ: BTW, 23.NxN/c6 struck me as a bad idea, as now the Black Rook on c6 can quickly swing over to the K-side ... and join in the assault. (Fritz confirms that this was a poor move.) BTW, I want to remind everyone that this is A. Geller, NOT E. Geller!!! |

| | LIFE Master AJ: [</= 23.gxh3? Qxh3+ 24.Kg1? (Better was: 24.Ke1 Bf4! 25.Ra3 Qxf3;  ) 24...Re4! (24...Re6!? ) 25.Bf4 (</= 25.Qe2? Rg4#) 25...Bxf4 26.Qc2 Nxd4! 27.Qxe4 (</=27.Nxd4? Qh2+ 28.Kf1 Qh1#) 27...dxe4 28.Nxd4 Bh2+ 29.Kh1 Bg3+ 30.Kg1 Qh2+ 31.Kf1 Qxf2#;
Best was: 23.Ng1 Bg4 24.Re1 Re7;  ] |
|
| Sep-17-11 | | Patriot: 22...Bxh3 is the only move I liked. 23.gxh3 Qxh3+ 24.Ke2 Rxe3+ 25.Kxe3 Re8+ (25.fxe3 Qg2+ followed by 26...Qxb2) 26.Kd2. Here I wondered which was better, 26...Bf4+ or 26...Qxf3, and decided to try the latter. 26...Qxf3 27.Re1 and for some reason I thought 27...Rxe1 made sense. I caught myself falling asleep while looking at this but geeze... |
|
| Sep-17-11 | | Yodaman: So was 21.Na5 a losing mistake? I don't see anything better. Could the puzzle have been started earlier? |
|
| Sep-17-11 | | izimbra: <Yodaman: So was 21.Na5 a losing mistake? I don't see anything better. Could the puzzle have been started earlier?> I think white can hold on to draw after <21.b5 axb5 22.Bxb5> |
|
| Sep-17-11 | | thegoldenband: I found 22...Bxh3 23 gxh3 Qxh3+ 24 Ke2 Rxe3+, with the win of the Queen after 25 fxe3 Qg2+, and figured something would work out (as indeed it does) after 25. Kxe3 Re8+. Briefly looked for other defenses, didn't see anything that challenged the main idea. |
