 | | OhioChessFan: <morfishine> White has a better game even after 37...Rxf2 but I think Black will hold. I'm still sliding forward and Black is okay in spite of that murderous Bishop staring down the e5 Pawn. Or did you miss the fact that in the game, Black didn't play the best move 37? |

 | | Once: <morfishine> The answer to some of these puzzles is not always the move I(or sequence of moves) played in the game. Sometimes, the players missed a win or, as in today's puzzle, a chance to draw. In today's puzzle, black missed a chance to survive. The move he played (37...Rxd6) loses. Instead 37...Rxf2 would have kept him alive. The "truth" about any position will generally unfold in the kibitzing. We have some excellent analysts on this site - human and silicon. If you read their comments, you will usually find out what is going on ... and what should have happened in the game wirh best play. As this site grows, I am coming to realise that the kibitzing is becoming as important as the database of games itself. Who knows? In future, chess historians may use CG.com's kibitzing as a valuable resource in its own right. Now that's a scary thought, when we think about some of the drivel that we type. Semi-naked ladies, indeed! |

| Dec-25-09 | | SgtPepper: The idea behind 37...Rxd6 is that it can't be followed by 38. Bxe5 as white would get crushed with 38... Rxd3 39. Bxb8 Rxd2 and he lost too much material for the queen. I thought that this was today solution. |

| Dec-25-09 | | cyclon: Note that after [37. -Rd7] 38.Qg4, answer is -Ree7, after which Rd3 is still en prise and if it moves off the d-line, Nd6 falls. 39.Nc4 is of no help because of -Rxd3 40.Rxd3 Bxc4 41.bxc4 Qxb2 wins a piece. Same applies with (37. -Rd7) 38.Nc4. Any suggestions? `En passant`;Have a nice Christmas for everyone! |

 | | sethoflagos: Merry Xmas one and all
Shades of yesterday. What I play at the board is
37 ... Be7 looking for
38 Qg4 Rxd6
39 Rxd6 Bxd6
40 Qe6 Be7
and if this holds I'm a minor piece to the good.
I look forward to seeing the correct line a little later. Cheers! |

| Dec-25-09 | | remolino: Black to play, 37...? Difficult.
My first reaction was to note that White´s position appears much stronger than Black´s (and White has an extra pawn), so either there is a tactical shot for Black or Black needs to find a defense. Going back to a recurring theme of the last two weeks, are we playing for a win or a draw? I would be happy with a draw in this position.
Second thing to note is lots of tension on d3 and d6. I think that Rd6 cannot be taken given weakness on e5 and White gets all sorts of couterplay plus a choice of continuations. 1. I will not even want to analyze all the ramifications of taking on d6 (neither with rook nor with bishop) since White has too many responses and the black squares on White´s kingside are weak. What else?
2. Taking on d3 seems more plausible:
37...Bxd3, 38. Nxf7 Kxf7, 39. Rxd3 and we have managed to simplify the position. Still White has the better position, he maintains an extra pawn, the rook is active on the d file and e5 is weak, but there seems to be a lot of play needed to convert the win. Still, this is favorable to White. What else?
3. 37...Rxf7! (I think this is it, it gets a pawn back). A. 38. Kxf7 Bxd3, 39. Rxd3 Bxd6 and e5 is triple protected. This position is greatly simplified and looks drawish. B. 38. Rxf7 Bxd3 and Black gets a pawn back white the position seems to hold. e5 cannot be taken given that the knight is hanging. Time to check. |

| Dec-25-09 | | newzild: Well, it took me four or five minutes to get this one today, but get it I did. I'd like to wish all you folks a great Christmas, even though it's Boxing Day here already! Thanks to the Chessgames staff for providing me with something to divert my mind each day. |

 | | SuperPatzer77: <remolino ...37...Rxf7> is a wrong notation> I was sort of confused about that. Now it is a correct notation - a) 37...Rxf2!!, 38. Kxf2 Bxd3, 39. Rxd3 Bxd6 = b) 37...Rxf2!! 38. Rxf2 Bxd3 =
<remolino> That's what you mean, right? You gave us a wrong notation - 37...Rxf7 - ????? It should be 37...Rxf2!! Well, Merry Christmas to you, <remolino>!! SuperPatzer77 |

 | | johnlspouge: Friday (Difficult)
J Becerra-Rivero vs H Spangenberg, 1994 (37...?) Black to play and win.
Material: B for N+P. The White Kg8 has 3 legal moves, of which Ba6 x-rays f1. The Black Ba6 attacks Rd3, but the White Nd6 also attacks Rf7. Black attacks Nd6 3x, whereas White defends it 2x. The Black Kg8 is secured from check, except for the pointless 38.Qxg6+. Candidates (37...): Bxd6, Rd7
I burned time on 37…Bxd6, and then missed 37…Rd7 38.<Qg4>. |

| Dec-25-09 | | remolino: Thank you SuperPatzer77 for the correction. Indeed I meant f2 not f7. Merry Christmas to you! |

|
| Dec-25-09 | | Quentinc: Well, a fun way to start Christmas. Took me forever but it did eventually appear to me that ...Rxf2 would save Black. The position is so complicated that I still don't quite understand why or how it does work, even after playing through the various lines! |
|
| Dec-25-09 | | WhiteRook48: I had ...Bxd6?! instead |

Unfortunately 38 Qg3 slaughters it :( |
|
| Dec-25-09 | | TheaN: Ooookay. Didn't get this one... still don't see why I can't take on d6 with the Bishop... Rxd6 Rxd6 Bxe5 is winning for White? Hm, well, as said, not even close xD. Merry Christmas everyone, who ain't rid of me yet :P. Well, as for premium it's until February :P. |
|
| Dec-25-09 | | King.Arthur.Brazil: Dear new chess-friends (can I call you that way?) I 've seen text Txd6 (I found it), but I spected Bxe5, so I'll take 2 Rs by the Q, with obvious: Txd3, Sxb8, Txd2, be it what it will be! But, Qxe5 tuns a mate problem to black, which is unsolved. So today we all become fools to try an impossible mission IV...laughts. Thanks, mery X-mas to everyone, good to be here with you!!! |

 | | patzer2: For today's Friday Christmas puzzle solution our present is the defensive gem 37...Rxf2! which was missed in this game. It wins back a pawn and is the only move to salvages drawing chances with near equality for Black. From the game continuation, it's easy enough to see 37...Rxd6? 38. Qxe5  is a losing proposition for Black. However, the possibility 37...Bxd3? 38. Nxf7 , which leaves White a pawn plus against three isolated Black pawns, involves a win that is a bit more complicated but worthy of study. Merry Christmas |

| | morfishine: <Once><OhioChessFan> Thanks! I'll be more open-minded and still seek the best move (not necessarily what was the next move), with the view that we may well find something better [despite how the game puzzle actually turned out] |

 | | David2009: Xmas day puzzle J Becerra-Rivero vs H Spangenberg, 1994 Black ...37?
Visited courtesy of Tactics Archive. 37...Rxd6? immediately loses to 38 Qxe5! etc so 37...Be7 first threatening Rxd6. This seems to hold: e.g. 38 Nxf7 Bxg5 39 Rd8+ (if 39 Nxg5 Bxd3) Bxd8 40 Rxd8+ Qxd8 41 Nxd8 Re8 42 Nxc6 Bb7 43 Nxe5 Bxe4
We have reached a difficult ending in which Black has the exchange for two Pawns.
Time to see how the game went:
=====
The annotator recommends 37 ...Rxf2. I need to study the position further. Meanwhile, playing my proposed line out over the board 41 ...Rd6! instead of Re8 wins the N and the game. White can play 38 Qg3 instead of Nxf7 (which I now see loses), but Black can defend with Rf4.
Time to read and digest the other kibitzes. |
