| independentthinker: What is the "the defensive ‘Wild Rook’ maneuver " - what book is this taught in? |
 |
| Mar-02-08 |
| Samagonka: At least I saw Rxf2 as the key move. I didn't have the peace of mind required to ponder the rest.
It's Sunday and my wife & kids won't let me...though. Anyway, I could also see it would take at least 3 moves to mate. White has enough space and mateerial after all. |

| Jimfromprovidence: IMO, 31...Nd6 is a subtle, absolutely brilliant move.
click for larger viewThe move threatens 32...Nc4+ with mate in two, but more importantly, it puts all of black's pieces in a coordinated, superb attacking position. As it turns out, no matter what white does, he cannot avoid losing material. |

| jovack: remove the defender of the g2 square and nudge the king into a mate.
I saw the first couple of moves and assumed it would be winning. |

| JG27Pyth: <IMO, 31...Nd6 is a subtle, absolutely brilliant move.> Agreed... I think the whole attack is impressive as a hell. Oh, when I said: <There's no way to know how deeply Smirin looked at all white's defensive options> I obviously meant Beliavsky! (Jeez -- I can't even visualize the correct name! :( ) FYI... thanks to you Kibitzers, and these puzzles, I'm playing in my first USCF rated event in 15 years this afternoon. I'm holding all regular posters here responsible for the outcome! Good or bad. ;) |

| johnlspouge: Sunday (Insane): Black to play and win.
Material: 2Bs for R+P. Black has a B+Q battery on the a8-h1 diagonal, Rd2, and Ne5 near the White Kg1. He has some back-rank vulnerability with the Ne8 protected only by the Qc6. His Rd2 is unprotected. The White Nf4 is overburdened: it protects against both the fork Nd6 and the threat Qg7#. Candidates (28...): Rxf2, Nd3, Nf3+
28...Rxf2 (threatening 29…Rxf4 [or 29...Rxg2+ 30.Nxg2] 30...Qxg2#) White might accept the sacrifice.
29.Kxf2 Nd3+ 30.Nxd3 Qxg2+ 31.Ke3 Bf6, threatening
32...Bg5+ 33.Nf4 [Kd4 Qd5#, an implicit theme below] Qf3+ 34.Kd2 Bxf4+ skewering Kd2 to Qc1. White has several responses.
(1) 32.Nf4 Qxg3+ 33.Kd2 [Ke2 Qf3+ 34.Kd2] Qxf4+,
with 2Bs+N+P vs. 2Rs and a violent attack.
(2) 32.Ne4 Qxe4+ 33.Kd2
[33.Kf2 Qg2+, déjà vu all over again, without Ng3 to play Ne4] 33...Qg2+ 34.Re2 [Kd1 Bf3+] [Ke3, déjà vu] Bg5+, and Black is toasted. (3) 32.Qd1 [Qb1 is worse]
32…Bg5+ 33.Nf4 Bxf4+ 34.Kxf4
[34.Kd3 Qxg3+ 35.Kc2, with the initiative, better K position, and 2Bs+N+P vs. 2Rs] 34…Qf2+ 35.Kg4 Nf6+ 36. Kh4 [Kh3 Qg2+ 37.Kh4] Qh2#
This line looks a little weaker than it should, and 32…Nd6 is an interesting but complicated alternative. Feasibly, White might reject the sacrifice by blocking the a8-h1 diagonal. 29.Ne4 [or Rxe4] Rxf4 30.Qxf4 Nd6, and the roof is caving in. Time to peek. The first three moves of the attack were a routine start, but the fourth one was the real puzzle, because it was required to justify the initial 28…Rxf2 sacrifice. I actually started on the 2-nd and 3-rd candidates before deciding they did not work. The move 31…Nd6 is thematic for the position, and probably better than my 31…Bf6 (although I think 31…Bf6 is good enough to win). The Ne8 is the only Black piece not participating in the attack, and most of White’s threats derive from the capture Rxe8. Time to check the kibitzing. I will set the computer on 31…Bf6 vs. 31…Nd6. |

Look at board
Black is down a pawn,and a rook. Is up two bishops.
Has more space and more board control.
Has domination of the white sq diagonal a8-h1 except for Nf4. Possible, Nf3+, Rxf2,
28. ...Nf3+ 29.Kh8 ...Rxf2 30.Rf1 ...Rxf4
31.Qc2 ...Rh4+

| johnlspouge: Toga II 1.3.1 declares my 31...Bf6 a dog, Beliavsky's and <dzechiel>'s 31...Nd6 a gem: [ply 15/58, time 03:33, value (for White) +0.73]
31...Bf6 32.Nh5 Bg5+ 33.Ndf4 Qh3+ 34.Kd2 Ng7 35.Re3 Qh2+ 36.Kd1 Nxh5 37.Re8+ Kg7 38.Ne6+ Kf7 39.Nxg5+ Kxe8 40.Qe3+ Kf8 41.Ne6+ Kg8 42.Rc1 Bd5 43.Nxc7 Qxc7 44.Qe8+ Kh7 45.Qxh5 Bxa2 Both White Ns defense of f4 was not something that occurred to me, but it was logical. [ply 15/67, time 13:57, value (for White) -3.77]
31...Nd6 32.Qd1 Bf6 33.Ne5 Bxe5 34.Kd3 Nc4 35.Re2 Nxb2+ 36.Kc2 Nxd1 37.Rxg2 Ne3+ 38.Kd3 Nxg2 39.Ne2 Bf3 40.Rf1 Bd5 41.a3 <<JG27Pyth> wrote: I obviously meant Beliavsky!> Beliavsky has a recognizable style (CG calls it "uncompromising"). So recognizable, in fact, you shocked me when you assigned it to Smirin! <<JG27Pyth> wrote: I'm holding all regular posters here responsible for the outcome! Good or bad. ;)> In that case, I wish you good luck :)
<dzechiel> pointed out that Black should keep the Ke3 suspended on the 3-rd rank and vulnerable for as long as possible, rather than recapture material. Also important was the fact that the Ke3 interfered with the Re1's control of the e-file, which is why Smirin tried to reactivate it with 32.Rf1 (although Toga gave 32.Qd1 as a better defense). |

| Jimfromprovidence: Just to show how powerful black's position had become, in addition to the text 33...Qd5 (which was good enough), black also had (as <RandomVisitor> first pointed out), 33...h5, threatening 34... Bh6+, skewering white's queen.

| johnlspouge: <JG27Pyth>, by the way, the variation 21.Ne6 fxe6 22.Rxe5
demonstrates "interference", with the Ne6 interfering with Re8's support of Ne5. |

| pawnofdoom: Lol I saw Qxg2# and was like "Oh wow this is too easy to be "insane." :D What makes this so hard is that the solution has so many "non-check" quiet moves for black to win |
|
| Mar-02-08 |
| drnooo: rather than the kt up to d6, doesnt black also have pawn h5 right away. Dunno if it is weaker, but does it not also lead to a forced win? |
|
| Mar-02-08 |
| drnooo: well maybe whites kt f5 foils the pawn to h5, dunno |
|
| Mar-02-08 |
| iccsumant: Anyway, these kind of problems can't be solved fully with raw analysis on the board. Black must have seen that he has many resources to continue the attack with and simply carried on with that line. |

| Amarande: <independentthinker: What is the defensive ‘Wild Rook’ maneuver> You may also know it as 'cling check' as that is perhaps more descriptive (in addition, the cling check motif can also be done in rarer cases by a Queen, so it's not limited to a Rook). Here's a rudimentary example:
click for larger viewWhite draws with 1 Rb5+, and then continuing to check on the b-file wherever Black's King goes, and the game is drawn, since Black can only ever escape the series of checks with KxR; however, this is stalemate no matter when or where Black does so. |

| Richard Taylor: I basically solved this. Although after Nc6 I thought White would play b3. Very complex. |
|

| Richard Taylor: I meant Nd6. Also Bf6 is a move to be considered. |
|
Mar-03-08
|
| johnlspouge: <<Richard Taylor> wrote: I meant Nd6. Also Bf6 is a move to be considered.> I actually calculated a few lines from 31...Bf6. Toga declared it to give White some pull, although not a winnning game (see my two posts). |

| SuperPatzer77: Why White resigns after 38...Ne3! is because White is falling apart -- 39. Qxe3 (only move) Qxe3, 40. Ne4 (prevents Qg5#) Qxe4, 41. Rf4 (only move) Qe2+, 42. Kg6 (if 42. Kh4 Qh2#) Qxd3+, 43. Kh5 Qh3+, 44. Kg6 Qe6+, 45. Kh5 Qe5+, 46. Kg6 Qg5+, 47. Kf7 Qxf4+, 48. Ke7 Qf8#. So, White tries his desperadoes against Black's mating threats but they don't work at all. 0-1 After 38...Ne3! 39. Kg6 Qe6+, 40. Kh5 Qg4# (or 40. Rf6 Qxf6+, 41. Kh5 Qg5#). 0-1 Too many mating threats are actually inevitable so, that's why White is falling apart. |

| Richard Taylor: <johnlsponge> I found 13 ... Nd6 and also thought of Nf6 or h6... I couldn't calculate all of them of course but I felt Black was winning...trouble was I spent a lot of time on 28 ... Nd3 and 28 .... Nf3+ and while doing so I had set my small portable board up with the W Queen on b8! So I was looking at 28 ..Nf3+ 29 gxf3 Rxf2 30 Rxe1+ Bf1 31 Rxf1+ and so on (when after 28 ..Ne3 29 Rxd8+ Kh7 the N was pinned (which it actually isn't in reality!)and I was obsessed with that line for some reason) ... but I also thought of 28 ..Qxg2+ but no dice...so all these lines and ideas distracted from the main idea of 28 Rxf2 then I saw Nd6 as essential to the attack..and possibly Bf6. Some interesting analysis you gave.
I usually avoid the "insane" problems - when I came on here a few years ago I did solve some of them - one by Keres and one by Tal etc but I used to spend too much time on them - I would analyse completely in my "head"! I don't have a computer - I do have Chessmaster but I have never set it up to solve much - occasionally I use it (use it more lately) ... For that (chess practice) the "easier" problems" are probably of more practical use but these are good from time to time - certainly a great combo by Beliavsky - a great game by both! Useful to see the themes as much as analysing specific variations... |
