|
| Jun-17-12 | | tivrfoa: 25. Rc6! is beautiful. |
|
| Jun-17-12 | | Zatrikion: White should exploit the fact that Black queen is dependent on the semi-open c file, controlled by the R on c8. So:
25.Nc6 Rxc6
(25..bxc6, 26.cxb4) or
(25..Qxc3+, 26.Qxc3 Rxc6, 27.Rxc6 Rxc6, 28.Qxc6 bxc6, 29.Kxb2) or
(25..Qb(c)5, 26.Rxf6 gxf6, 27.Ne7+ Kf7, 28.Nxc8)
mainline continuation:
26.Rxc6 Rxc6
27.Qxd5+ (with mate in few moves)
Time to check if this is correct this time... |

| Jun-17-12 | | gaurav33: Wow,never think in this way.First i thought Re8+ ,but soon realize it will not work.Really today's puzzle was very difficult. |
|
| Jun-17-12 | | vinidivici: hey,how about black respond is 25...Rcxc6 ???

6/7 for the week with a pass!

| Jun-17-12 | | DarthStapler: I didn't get it |
|
| Jun-17-12 | | emate: I had in mind a totally different solution:
how about 25 Re8 ?
I figured that if black captures with his rook: 25 ... R:e8 then white wins blacks queen, and if 25 ... B:e8 26 R:e8 and again black can't capture with his rook, and 26 ... Kf7 just looses the exchange with 27 R:c8. Am I missing anything? I guess the moves that were played are stronger, but the tactic of 25 Re8 wins too. |
|
| Jun-17-12 | | Mendrys: Wow, 25. Rc6 isn't a move that easily comes to mind, unless you know precisely what to look for, which I didn't. The key to the combination is blacks weak d5 square which white can occupy with check. If the black king were on say f1 instead of g1 then the the best white can do is take the knight with 25. Qxb2 where black can just reply 25...Qxd4. |
|
| Jun-17-12 | | Mendrys: <emate> I think black can just reply 26...Rf8 and stymie white by something like 27. Rxc8 Rxc8 28. Ne2 Na4 and now black is up the exchange.

| Jun-17-12 | | Marmot PFL: White has some problems with his king safety in this position. It looks like he needs to put something on c6 to block the Rc8 and thus threaten cxb4. 25 Nc6 looks tempting but black can play Qa3 with his own threats. After 26 Qxb2 and trading it looks about even. 25 Rc6 is more forcing as Rxc8+ is threatened. After 25...Rfxc6 26 Nxc6 white has the added threat Qxd5+, 25...Rxc6 26 Qxd5+ Kf8 (Bf7 Re8+) 27 Qd8+ Kf7 28 Qe8+ Kf6 29 Qxc6+ and cb4 wins the queen. However if black does not take this knight he is threatened with not only cb4 and Qxb2 but also Ne7+, so this looks winning for white. |

 | | scormus: Sigh, didnt get 25 Rc6. How can such a natural move be so hard to see as winning? 3 f3. I never realised it was ever played at master level, let alone had a name. But I like the diagonal string ... RppppppR |
|
| Jun-17-12 | | rilkefan: For what it's worth, stockfish evaluates Nc6 as +1.3 at a depth of 25: ...Qa3 26.Ne7+ Kf7 27.Rxf6+ gxf6 28.Qxb2 Rxc3 29.Bc2 Qa5 30.Nxd5. Rc6 is +4 or so. |
|
| Jun-17-12 | | TheBish: Wow, that's incredibly deep! I thought I did pretty well (close but no cigar with 25. Nc6), but I didn't even consider 25. Rc6 for some reason. I think that's one of my weaknesses, analyzing a few lines fairly deeply, but not considering enough candidate moves. Both moves result in similar positions, but the difference is the position after 25. Nc6 Qa3 (which I didn't consider) 26. Ne7+ Kf7 27. Rxf6+ gxf6 28. Qxb2 Rxc3+ 29. Bc2 Qa5! 
click for larger view...is that White can't play 30. Re5 (in the other line the f6 pawn is back on g7), and White can't save both his knight and rook (30. Nf5 Rxc2+ 31. Qxc2 Qxe1). My mistake was failing to analyze 25. Nc6 Qa3!. Having said all that, Fritz says White is still winning (from the diagram position) after 30. Qxb7! Rxc2+ 31. Kxc2 Qxe1 32. Nxd5+ Kf8 (best) 33. Qb4+!, trading queens and winning the endgame anyway as White will win the a-pawn and go two pawns up. |

| Jun-17-12 | | TheBish: W Watson vs M Stangl, 1998 White to play (25.?) "Insane"
(Forgot to post this before my follow-up post above! It will make more sense after reading this.) Material is even, but Black is threatening ...Rxc3+. After 25. Qxb2 Qxd4! (not 25...Rxc3+ 26. Nc2). One thing to look for is a way to deflect Black's Rc8, but if 25. Re8+ Bxe8 26. Rxe8+ Rff8! and White has just given away a rook. But there is another, much harder to see (hence "insane") way to interfere with the Rc8. 25. Nc6! Rxc6
Forced; if 25...bxc6 26. cxb4. Otherwise, White continues 26. Ne7+. 26. Rxc6 Rxc6
Otherwise, White wins the Exchange.
27. Qxd5+ Kf8
Not 27...Kh8?? 28. Qd8+ and mates, or 27...Bf7? 28. Re8+ Qf8 29. Rxf8+ Kxf8 30. Kxb2, winning the queen for a rook. Now not 28. Qxc6? Nd3+! 29. Bxd3 (or 29. Kd2 Qb2+) Qa3+ 30. Kb1 bxc6 and wins for Black. 28. Qd8+ Kf7 29. Qe8+ Kf6 30. Qxc6+! bxc6 31. cxb4 Nc4 32. Re6 and White has won the Exchange and will mop up in the endgame. I would say the difficulty level is justified; this was a mental workout, even if I missed something! |

| Jun-17-12 | | Shams: <scormus> <3 f3. I never realised it was ever played at master level, let alone had a name.> More than one, actually-- it's also called the "Fantasy Variation". As near as I can tell, that's because any notion that White can use it to gain an advantage, is pure fantasy. |
|
| Jun-17-12 | | sevenseaman: 25. Rc6 and the idea behind it is a rare combination. It is an absolutely logical move but will not occur easily. The thought came to my mind when I read <scormus>'s <Sigh, didnt get 25 Rc6. How can such a natural move be so hard to see as winning?> Obviously Nc6 is the more natural move that easily occurs. But this latter move carries an intrinsic flaw; it provides Black with a tactically dangerous option. |
|
| Jun-18-12 | | ianb902: Based on the text (28.Qxd5), I believe White's win would have been more decisive with 28.Qxh7+ Kf7 (if Kf8, 29.Qh8+ forces the King to move to f7 anyway) 29.Qxh5+ g6 30.Qxd5+ Kf8 31. Qd8+ Kg7 32. Re7+ and black will have to exchange the Rook for his Queen to avoid mate. Queen and Bishop for a Rook is better than being up by a Rook. If 29...Kf6, 30.Qg6#
If 29... Kg8, 29.Bh7 Kh8 (if 29...Kf8, 30.Re8#) 30. Re8 Qf8 31.Rxf8# If 29. Kf8, 30.Re8#
Nice puzzle of the day. |
|
| Jun-18-12 | | rilkefan: <<Shams>: As near as I can tell, that's because any notion that White can use it to gain an advantage, is pure fantasy.> It's striking that white soon plays f4. |

| | scormus: <Shams ... fantasy variation> Perfect name. Until I saw this game my only expereience of it was when I was trying to cure my insomnia by thinking up chess opening variations. I difted into dreamland with the idea of 1. e4 c6 2. d4 d5 3. f3 dxe4 4. fxe4 e5 5. Nf3 exd4 6. Nxd4 Qh4+ |
|
| Apr-08-18 | | Saniyat24: many clever maneuvers, but the simple 21.c3 was just as important...beautiful structures and positioning by White...! |
