| Aug-05-07 | | stanleys: <Autoreparaturwerkbau:><23...Rd2!! Just... awesome> I could only agree! |
|
| Aug-05-07 | | Peter Johnson Ng: It destroys white defense completely. OOh! |
|
| Jun-06-08 | | ezmerin: Worth being a GOTD. Here is the pun: "A Ruud awakening." |
|
| Mar-26-09 | | nimzo knight: GOT IT. Always satisfying to get thursday, as I normally have no hope Friday onwards. Bishop is pinned, due to mate of h2. If RxR ,Bf3+ |

 | | SuperPatzer77: 23...Rd2!!! Thunderbolt!!!!
That's a real killer!!!
24. Rf1 (only move) Qxf1+!!, 25. Bxf1 Bf3+, 26. Bg2 Bxg2+, 27. Kg1 Bc5#! 0-1 SuperPatzer77

| Mar-26-09 | | Eduardo Leon: My thought process was like this:
1. The two main defending pieces are the bishop at e2 and the rook at d1. Both control f1 and the bishop also controls g2. 2. If black could deviate these pieces from their posts in the two following moves, then he would play 25. ... Qf1#. 3. Deviating the bishop is easy, by playing 23. ... Bf3+. If 24. Kg1 (to not take the bishop), then 24. ... Qg2#. However, after 24. Bxf3, how does black deviate the rook? 4. I realize that, after 23. ... Bf3+ 24. Bxf3 Rd2, black threatens 25. ... Qxh2+, and 25. Rxd2 isn't possible because of 25. ... Qf1#, of course. However, after 25. Ne2, white defends the second rank successfully and is a piece ahead. 5. Of course, the next thing I did was inverting the order of the moves: 23. ... Rd2, threatening 24. ... Bf3+. If 24. Rxd2, then 24. ... Bf3+. If the bishop moves, then 24. ... Qxh2#. And white can't play 24. Ne2. Therefore, 23. ... Rd2 wins. |

| Mar-26-09 | | onesax: At first I saw black had some potential threats with his two powerful bishops, but due to the fact that white is threatening back-rank mate, I realised that the first black move had to be a check. I threw 23. ... Rxd1+ 24. Qxd1 and 23. ... Qf1+?? 24. Rxf1 out the window quickly, leaving me the idea of 23. ... Bf3+. After the obvious 24. Bxf3, it took me about 15 seconds to see 24. ... Rd2 threatening mate along the now-clear 2nd rank, to which white cannot adequately respond with 25. Rxd2 becaue his own back-rank is weak and prone to 25. ... Qf1 mate. However playing over it now I see that I missed white's defensive resource 25. Ne2! (or even Be2) blocking the 2nd rank and claiming the point. That is why Sokolov switched the move order I intended and went with the winning 23. ... Rd2!!, which wins via the same strategy with a subsequent Bf3+, but it is important to get this right [which I did not :(] |
|
| Mar-26-09 | | Eduardo Leon: Oh, I didn't see 24. Rf1. Of course, as SuperPatzer77 said, if 24. Rf1, then 24. ... Qxf1+! wins. In this line, black's dark squared bishop plays an important role too. |
|
| Mar-26-09 | | zooter: Looking at the position the first thing that strikes me is that white is about to checkmate black by 24.Rxd8. So whatever black does has to involve either a checkmate or moving the rook 23...Rd2 seems like a strong move. Initially I thought this threatened the bishop (which is protected only once by the knight but attacked twice by the rook and bishop), but off course any "pass" move by white and black can go wrong by 24...Bxd2 25.Nxd2 Rxd2?? 26.Rd8# But looking deeper at the position I see that after the initial move, black is threatening mate by 24...Bf3+ 25.Bxf3 Qxh2#
24.Rxd2 is obviously a poor move because of 24...Qf1# and no good is moving the bishop off the second rank...So what can white do? Maybe 25.Kg1 , but then the bishop joins the attack by 25...Bc5+ I frankly don't see any good defense here but then again i'm not good at finding defenses. Time to check how this went down |

 | | dzechiel: Black to move (23...?). Material even. "Medium"
The two moves I want to play are ...Rd2 and ...Bf3+, but I need to get the order correct. I think it must be
23...Rd2
threatening 24...Bf3+. What can white do here? If
24 Rxd2
then
24...Bf3+
anyway. White plays
25 Bxf3 Qf1#
If instead 25 Kg1 then 25...Qg2#.
I think this is it. Time to check. |
|
| Mar-26-09 | | zooter: hmmm...
I thought 25.Rf1 Bf3+ still wins, but that is wrong.
After 25.Rf1 Qxf1+ 26.Bxf1 Bf3+ 27.Bg2 (not a great defense, just increases the move count) Bxg2+ 28.Kg1 Bc5# Only half a point for me here |

 | | Infohunter: What a crusher! There just isn't any answer to 23...Rd2! |
|
| Mar-26-09 | | Eduardo Leon: We all agree that 23. ... Rd2! is the first move.
After 24. Rf1, black can win with the obvious 24. ... Bxe2, winning a piece, or with 24. ... Qxf1+!, mating in four moves. |
|
| Mar-26-09 | | Eduardo Leon: And I just noticed there is a third possibility:
23. ... Rd2 24. Rf1 Rxe2!, winning too, because of the threats 24. ... Qg2# and 24. ... Qxh2#. Of course, if 24. Nxe2, then 24. ... Qxf1#. |
|
| Mar-26-09 | | Philistine: After a very poor showing last week, I am 4/4. Is it me, or are the puzzles easier this week? |

 | | Jimfromprovidence: 24 g4 must also be discussed.
click for larger view Black wins the queen with 24...Bxg4 25 Nb1 Qxb3.
(25 Nb1 avoids mate because if, for example, 25 Kg1 then ...25 Bc5+ 26 Kh1 Bf3+ 27 Bxf3 Qxf3#). |

 | | An Englishman: Good Evening: I saw both White's threatened mate in one and that if the White Rook were not on d1 or d3, then ...Bf3+; Bxf3,Qf1X. Ironically, only my threatened Rook can lure the White Rook to an appropriate square: hence, the game-winning move presented itself. Even if I found it, it's still beautiful. |
|
| Mar-26-09 | | Woody Wood Pusher: Micro-second solve.
Nice move though! |
|
| Mar-26-09 | | mohitm: wow! But i thought of Rd3, i think it too will lead to same thing. |
|
| Mar-26-09 | | LimSJ: wow, looks like a bus at full speed along D street then STOP. end of tempo. deadend (for white, that is.) |
|
| Mar-26-09 | | BlackWaive: Took me about 5 minutes to find the solution.
I was trying to prevent a back-rank counterplay for most of that time, until I found the combination 23...Bf3+ 24. Bxf3 Rd2. However, the mate is stopped when the Bishop moves back to e2, so I switched the move order around and finally got it. There is no response after 23...Rd2 followed by 24...Bf3+. I need to pick up on mating themes, since this one wasn't obvious to me. |
|
| Mar-26-09 | | SamAtoms1980: 23 ... Rd2!! 24 Rxd2 Bf3+! 25 Bxf3 Qf1 mate!!!
The punctuation corresponds with how hard I'd be banging down the pieces. |
|
| Mar-26-09 | | percyblakeney: It took me a while to realise that the rook could be moved along the d-file without capturing on d1, but once you see that I think the very nice solution jumps out rather quickly. |
|
| Mar-26-09 | | Stormbringer: Missed it. Didn't even look at Rd2, spent a lot of time looking at Rxd1 but couldn't make it work. |
