| Nov-13-05 | | greyfox: ive considered Nxf2 but i couldn't find a force win that's why i disregard it.. now i know that it would be helpful to trust your first instinct.. |

 | | cu8sfan: <I got 27 ... xf2, but I followed with 28 ... xe4, eventually winning the knight on f3. I'm not sure why my line is weaker.> I found the same line and couldn't believe I had solved a Sunday puzzle. |

| Nov-13-05 | | dwojiow: I calculated:
27...♘xf2
28.♖xf2 ♗xe4
29.♗g2 ♗xf3
30.♗xf3 ♗xf2+
31.♔xf2 ♖xd2+
32.♖xd2 ♕xd2+ 
This seems easier than the game continuation, but I could be missing something. But after 28...♗xe4, what is better than 29.♗g2? |

 | | al wazir: I don't see how 29. Kg2 can be white's best defense, since 29...Bxf2 forces the king to make an extra move in recapturing and then getting checked again. How about 29. Bxe5 Bxf2+ 30. Kxf2 Qc5+ 31. Kg2 instead? Then if 31...Bxe4, 32. Nxe4 Rxd1 33. Qxd1 Rxd1 34. Nxc5 bxc5, leaving white with two bishops for a rook and a pawn. My solution was the same as <benveniste>'s, 27...Nxf2 followed by 28...Bxe4. |
|
| Nov-13-05 | | erimiro1: I got the idea, but didn't follow it to the end. Funny, that Planinc, one of the artists of chess combinations, got caught into one by Lombardy. |
|
| Nov-13-05 | | Soltari: I found Bxe4 too. White can't take with the knight, cause that would lose a rook (28...Rxd1). If white takes with the rook (28.Rxe4), that leaves the f2 pawn undefended and can be taken by the knight (28...Nxf2), this pins the king too (cause of bishop on c5), and the knight forks a bishop and a rook. Looks like a winning situation to me. |
|
| Nov-13-05 | | JGreene82884: What is Fritz? |
|
| Nov-13-05 | | Soltari: @JGreene82884,
Chess computer program. |
|
| Nov-13-05 | | Autoreparaturwerkbau: At the point where the puzzle begins, there are only 4 captures made out of 53 half-moves played, which makes the puzzle the real-deal Sunday-one. It is extremely difficult to spot the solution with 28 pieces on board + no forced moves. Then of course, in the remaining 17 half-moves there is 10 captures, and the game is all finished. |

| Nov-13-05 | | Averageguy: <JGreene82884>Welcome to the site! |
|
| Nov-13-05 | | Frankly: Mmmm.... I would have played Nxf2, but for the wrong reasons. Maybe could fool myself that the real ones would then have occurred to me on the hoof. Or not. |
|
| Nov-13-05 | | apoorv: first move was easy to come up with, but couldn't follow it through all the way |
|
| Nov-13-05 | | makaveli52: ok i will give some of the lines I got from Fritz, here is the main line, every move favored by Fritz:
27...Nxf2
28.Rxf2 Bxe4
29.Kg2 Bb7
30.Rff1 Rxd2+
31.Rxd2 Qxd2+
32.Kh1 Qe2
33.Bg2 Rd8
34.Bc3 Rd3
35.Qe1 Qc2
36.Qxe5 Qxc3
37.Qxc3 Rxc3
Black is up a bishop and a pawn with much stronger position and a clear win
if the defence is 29.Bg2, Fritz recommends this:
29...Bxf3
30.Bxf3 Rxd2
31.Be2 Rxd1+
32.Qxd1 Qxd1+
33.Bxd1 Rd8
34.Be2 Rd2
35.Ba3 Bxa3
36.Kf1 Bc5
Black is up 2 pawns and a knight, with a better position, also a clear win
if 29.Bxe5 although Fritz recommends 29...Rxe5, 29...Bxf2+ also works
30.Kxf2 Qc5+
31.Kg2
31...Nxd1 is wrong
31... Rxd2+
32.Rxd2 Bxb1 winning the queen
a better defence then 31.Kg2 is
31.Bd4 Rxd4
32.Nxe4 Rxd1
33.Nxc5 Rxb1
34.Na4
Black is up 2 exchanges, but white ends up having 2 passed pawns on the b and c files, so white has slight counterplay, but is still down a lot
I might have some typos, and errors, but all these lines were produced by Fritz, so they should be correct |

| Nov-13-05 | | Lion83: Very nice game!
I like 14...Bc6 inducing white to play b5 giving black an ideal outpost for his bishop. Then he slowly improves the position of his pieces getting ready to attack. The rook finds a great square on d3. The Queen adds pressure down the d-file and then 24..h5, the final touch before the knight is brought into the attack.Now black strikes with Nxf2! The rook which was a key defender in whites position is forced into a pin. Now Rd8 makes perfect sence adding more pressure down the d-file. Bxe4 was the move I looked at and Fritz seems to think this is actually stronger then Rd8 and it's very logical.
Nxf2 removed a defender of e4 and d2 and now black takes full advantage. The bishop attacks the currently undefended f3 knight which has to stay and protect the d2 knight, it also sets up a discovered attack on the white queen. Unfortunatley for White there seems to be no defence and his position falls apart. Fritz suggests Kg2 as whites best move hoping black will play Bxf2 when white would respond Nxe4.
However after Bxf3+ or Fritz suggestion Bb7 black wins. |
|
| Nov-13-05 | | DaVinciCodePHI1.618: ♘xf2! creates a bit more space for black and cleverly pins the white ♖. A great game, although I have never been a fan of the more 'uncommon' openings such as g3. |
|
| Nov-13-05 | | EmperorAtahualpa: I was thinking of 27...Ne3, so got it wrong. Too difficult puzzle for me, but the fact that it's Sunday is a consolation. |
|
| Nov-13-05 | | FORTRAN 77: I was thinking Bxe4 |
|
| Nov-13-05 | | FORTRAN 77: and the line was:
27....Bxe4
28.Nxe4 Rxd1
29.Kg2 Rxb1
30.Nxd6 Bxd6
where Black won Pawn, Rock and Queen and
lost Bishop and Queen and didn't evaluated further |
|
| Nov-13-05 | | FORTRAN 77: and probably black was thinking after 27. Re1 White can take the Knight so they sacrificed it because one move earliar when black played Ng4 white cant take on g4 becase after hxg when the knight move the other on d2 is hanging after Rd1 Bxg4 is possible |
|
| Nov-13-05 | | alexandrovm: Very nice combination with many "in between" moves, I had to see the answer (lack of time), white's position was really dificult to defend,... |
|
| Nov-13-05 | | DutchDunce: Dern. I knew it had to be something taking f2. But I chose the bishop. |
|
| Nov-13-05 | | kevin86: I yield the Sunday puzzles to the experts;I just like to sit back and admire them. |
|
| Nov-13-05 | | avidfan: To <makaveli52>: The last variation after 31... Rxd4 is faulty. A white pawn is on e4 so 32.Nxe4 is illegal. A FEN diagram would be helpful. |
|
Nov-14-05
 | | Richard Taylor: I missed this (I thought b:e4 was winning) but would have probably played Nxf2 OTB based on its thematic and Black can double on the d file etc but I certainly didn't see Lombardy's continuation - great game. |
|
| Nov-21-05 | | patzer2: Black's 27...Nxf2! is a demolition of pawn structure combination, which uses a key series of pins and deflections. |
