| Aug-21-07 | | vonKrolock: <15...♘f5>! Starting an extraordinary combination - With the advance in development, and almost all his pieces in agressive posture, Segal have not to care for - a ♙... <16...♖ac8>! ...another ♙... <18...♘g3>! ...a whole ♘ <19...♖xc1>! Now all becomes perfectly clear: black is winning |

 | | Phony Benoni: <18...?> is a weekend puzzle if ever I saw one. |
|
| Feb-14-11 | | swordfish: Wow - impressive game by the Romanian against the man who would be a Candidate in the following cycle. |
|
| Apr-15-12 | | newzild: SUNDAY: 12.18pm - 12.36pm
Black is down by two pawns but is fully developed. White's queenside pieces are AWOL. Let's try the most obvious candidate first: 17...Nxd3
18. cxd3 Rxc1
19. Rxc1 Qxb2
20. Qxb2 Bxb2
21. Nd2 Bxa1
22. Rxa1
Black is still down a pawn. However, it's interesting that after 18...Rxc1 White's rook no longer defends f2, and Black has a battery aimed at that square. So, let's try: 17...Nxd3
18. cxd3 Rxc1
19. Rxc1 Ng3
This looks pretty strong because of the twin threats 20...Ne2+ and 20...Qxf2+ 21. Kh1 Qf1+ 22. Rxf1 Rxf1#. a) 20. Rf1 Nxf1 
b) 20. Rc2 looks adequate
How about:
17...Nxd3
18. cxd3 Rxc1
19. Rxc1 Nd6
Hitting the queen.
a) 20. Qf3 Qxb2
b) 20. Qxa7 Qxb2 21. Na3 Bd4
c) 20. Qa6 Qxf2+ 21. Kh1 Bxa1
This seems to do the trick, though I'm not too confident today. Time to check. |
|
| Apr-15-12 | | newzild: Well, looks like I fluffed another Sunday. Rybka says my line only gives a slight advantage to Black because White can give up his knight on c3, rather than play it to a3. I missed that possibility. <whiteshark> The fortress idea is interesting, but I think White can force the exchange of his queen for rook, knight and pawn, which leaves him a pawn up in a K+P ending. I'm going to take a closer look at the position. |
|
| Apr-15-12 | | vinidivici: great game from Segal. thats why u have to develop your pieces wisely at the beginning. White didnt care about that. And that cost him a game. Ng3 is a good move. i cant see too deep after that. but white's exposed king, white's many undevelop pieces, and black's rook at the f file....i think thats a very good position for black. |
|
| Apr-15-12 | | rilkefan: I'm looking (with a board, sadly) at 17...Nxd3 18.cxd3 Ng3 19.Be3 Nxf1 20.Kxf1 Rc1+ 21.Ke2 Qxb2+ 22.Qxb2 Bxb2 23.Nd2 Bxa1. If instead 19.hxg3, then ...Rxc1 20.Rxc1 Qxf2+ 21.Kh2 Rf5. Guess I must be missing something, as this seems too straightforward for a Sunday. Well, ok, how about 19.Nd2? After ...Nxf1 20.Nf3 the black knight is trapped, but white's position is poor - oh, yeah, ...Rxc1 and ...Qf4+ forking. Maybe 19.Nc3 shielding c1 is better - then ...Nxf1 20.Qxa7 Nxh2 21.Kxh2 - but instead of ...Qxf2 I guess ...Qh4+ and ...Bd4 wins. Well, let's see the game. |
|
| Apr-15-12 | | rilkefan: Oops, Rc4 defends after my 21...Rf5 above. The immediate ...Qe3 is better, as white has to take on g7. If I had seen the game continuation OTB and missed 21...Qe3, I probably would have played 17...Nxc2 with approximate equality and usual tactics instead, assuming I was sober. Back in the day though I would have leaped then looked. |
|
| Apr-15-12 | | VincentL: "Insane".
The first sequence that strikes me here is 17.....Nxd3 18. cxd3 Rxc1 19. Rxc1 Nd4. Now white has the threats Qxf2+ (followed by mate on f1 with Be5 to follow if h3 is played)
and Ne2+. If the queen moves there is Qxb2.
I am sure this is along the right lines, but I am too tired to analyze thoroughly. Let´s check. |

 | | Jimfromprovidence: Great game.
17...Nxd3 18 cxd3 looks normal, then 18...Ng3! is very nice. 
click for larger viewIf white can ignore the knight on his doorstep he has 19 Bg5?!. 
click for larger viewBut black sidesteps this threat nicely with 19....Ne2+, then takes the bishop next move. |
|
| Apr-15-12 | | tcoxon39: The line I came up with is:
17. ... Nxd3
18. cxd3 Rxc1
19. Rxc1 Ne3
The only viable defense I see for white is:
20. Nd2 Qxf2+
21. Kh1 Bxb2
From here black can capture a rook and a knight with little threat from white. Black ends up trading a knight, a rook, and a bishop for 2 bishops, a rook, a knight, and 2 pawns. |
|
| Apr-15-12 | | standardwisdom: Isn't 26 Qh6+ slightly better than the text? Better to take the developed rook than the a1 one, and also seems to keep tempo, a pawn and the queen in a better spot. I am sure I am missing something, so bring me down quickly please, or it may be a hard fall later. |
|
| Apr-15-12 | | mig55: 22. .../Qe3 is not good while white has Nd2, 22. ../R f4 is much better. Wins immediatly. |
|
| Apr-15-12 | | fetonzio: didn´t think too hard, just thought the solution would have sth to do with marshall´s famous Qg3 sac |
|
| Apr-15-12 | | stukkenjager: 17...Nxd3 18.cxd3 Ng3! 19.hxg3 Rxc1 20.Rxc1 Qxf2+ 21.Kh1 (21.Kh2 Be5) 21...Qe3 game over, Ng3 very nice indeed. |
|
| Apr-15-12 | | luzhin: 47...e3+ finishes off neatly. If 48.Rxe3 Qxf1+! 49.Kxf1 Kxe3 is a won K+P ending. |
|
| Apr-15-12 | | morfishine: Thought <18.Rxc1> was the follow up. Sweet the way Black finally scooped up the knight winning |

| Apr-15-12 | | sevenseaman: I had a busy day and it looks way beyond a tired, drowsy mind. Black is 2 Ps off the pace but way ahead in development. A line;
<17...Nxd3 18. cxd3 Rxc1 19. Rxc1 Nd4 20. Rf1 Ne2+ 21. Kh1▢ Qxb2 22. Qxb2 Bxb2 23. Re1 Bxa1 24. Rxe2 Bd4 25. Kg1> is one line that comes to mind. Black K will need to move up. Looks drawish even though White is still a P to the good. Let me see some more.
Another line;
17...Nxd3 18. Cxd3 Ng3 19. hxg3 Rxc1 19. Rxc1 Qxf2+ 20. Kh1▢ Qe3 21. Nc3 Qh6+ 22. Kg1▢
Bd4#
Looks too pat for a Sunday. I may have missed some good defensive response and someone is sure to point out. But a line worth a good look.
Thats all for me, today. |
|
| Apr-15-12 | | mig55: Sorry, I had it wrong, I had the pawn on h6.... |
|
| Apr-15-12 | | cyclon: After couple of busy days that I had to skip the puzzles let's see this one. My line today is; 17. -Nxd3 18. cxd3 ( N-O-W 18. -Rxc1? 19. Rxc1 and -Ne3/d4/d6/g3/h4 or -Qxb2, or Qg5 just do NOT quite get there - B-U-T... ) 18. -Ng3 does the magic; 19. hxg3; < ( or 19. Bg5 Rc1 [ a 'magic' move here ] 20. Bxc1 [ only move as far as I'm concerned - Black threatens mate both from f1 and f2, whereas Qxg7+ Qxg7 should win for Black] 20. -Nxf1 is pretty good for Black e.g. 21. f3 Nxh2/ 21. Qxa7 Nxh2 ( 22. Kxh2 Qh4+ 23. Kg1 Bd4 ) / 21. Qf3 Qh4 and if White renounces his Queen Blacks position remains more active - like in general in this 17. -Nxd3 18. cxd3 Ng3 19. Bg5 Rc1 20. Bxc1 Nxf1 line there's no immediate win for Black, but definitely his game is much more dynamic owing to the fact that White lacks seriously in his Queen-sides developement > )
19. -Rxc1 ( now it's the time ) 20. Rxc1 ( 20. N- Qxf2+, 20. Qf3 Qxb2 both curtains, or 20. f- Qd4+ done ) -Qxf2+ 21. Kh1 < ( 21. Kh2 (?) Be5 over sooner ) > -Qe3 is a winning move for Black in this position , because now there's no move to save Whites game; < ( 21. -Qxg3? is too slow [ 21. -Rf5/f4 just don't make the day either ] ) > for example; < >
22. Qe7/e4 Qxc1+ 23. Kh2 Qxb2 taking the Rook without danger
< >
22. N- Qh6+ mates
< >
22. Qd7 Qxc1+ and 23. -Qxb2
< >
22. Qc6 Qh4+ 23. Kg1 Bd4X
< >
22. Rg1 Qh6X
< >
"Transmission ended". |

| Apr-15-12 | | gofer: White has obviously been munching pawns, but has neglected to develop
his bits. So the two pawn advantage can quickly disappear in a whithering
attack on his under-protected king. The problem for white is that is
he doesn't follow the forced sequence he is going to go a whole piece
down and that isn't going to get him very far, when his Ra1 is still
boxed-in.
<17 ... Nxd3>
<18 cxd3 Rxc1>
<19 Rxc1 Nd4!!>
The whole point of exchange. Black threatens Qxf2+ mating and Ne2+ winning
the rook. There is only defense to both threats.
<20 Rf1 Nc2!>
Black switches tack and goes for the boxed-in rook because the other rook
is defending Pf2 against the mating threat, so cannot come to the aid of
Ra1! So black can take Ra1 without fear of being taken back!! Now the
continuation for white is not clear to me.
21 Nc3 Nxa1 22 Ne4 Qxb2 23 Qxa7 Nc2 24 a4 Nd4!
The a-pawn is going no where, but black is threatening to marshal the
rook and king into a very tight corner. So perhaps white will try a
simple pawn march!
21 b4 Qxa1 
<21 Qxa7 Nxa1>
<23 b4 Nc2>
<24 b5 Nd4!>
<25 a4 Ne2+>
<26 Kh1 Qh5!>
Time to check...
~~~
I looked at Ng3, but discarded it. I wonder if my line holds water?! |
|
Apr-15-12
 | | paulalbert: Had the right ideas, but totally missed the right move order and focused too much on Ne3 instead of Ng3. To get Sunday right requires much more calculating vision and precision than I'll ever have. |
|
| Apr-15-12 | | cyclon: < rilkefan: I'm looking (with a board, sadly) at 17...Nxd3 18.cxd3 Ng3 19.Be3 Nxf1 20.Kxf1 > and here Black plays simply 20. -Qxb2 winning the Rook whether White exchanges Queen or not having an easily winning game. |
