| Jul-20-22 | | ChessHigherCat: I swear the ONLY reason I got this was that I kept asking myself why I shouldn't pay the immediate rook sacs that were screaming to be played like an apoplectic maternity ward. That made me think the "quiet move" must be it, so I played
28. Nf4 Nxf6 29. Nxg6 Nxh5 30. Ne7+ Kh8 31. Rg8+ Qxg8 32. Rxg8#
That said, I doubt that I correctly anticipated Black's defenses, but when torn between finishing my rush job by midnight or wasting even more time analyzing the hell out of this position, I reluctantly choose to vamoos. |
|
| Jul-20-22 | | ChessHigherCat: Ach, hach, the rook sacs really did work, but I think my line works, too. Okay, critics, rain on my parade. |
|
| Jul-20-22 | | ChessHigherCat: Okay, I can see that I have to resort to reverse psychology with you guys: Please critics, i beg of you, don't rain on my parade! What about you <Granny O Doul>, I rembember you were a strong player and you've already found and analyzed 28. Nf4. Vut you tink about my line? Did you go through the same thought process of avoiding the rook sacs as too obvious for a Wednesday puzzle? |
|
| Jul-20-22 | | stacase: If White's Bishop and Knight weren't so nicely placed, the "Wham bam thank you Ma'am" approach wouldn't have worked. |
|
| Jul-20-22 | | jrredfield: 3 for 3 this week. I still say Monday was harder than these last two nights. |
|
| Jul-20-22 | | Granny O Doul: @CHCat: I didn't feel 28. Rxg6+ was too obvious but I did keep in mind that there is often more than one good move. I usually think simply "what would I do here?" and to increase the verisimilitude, imagined I had only seconds on my clock to reach move 30. Under those circumstances, 28. Nf4 had a lot to recommend it. But yes, after 28...Nxf6 then 29. Nxg6. Otherwise it could get tricky. |
|
| Jul-20-22 | | AIC: Couldn't see all the way thru as Mr. Gofshtein did. I thought the knight and bishop should also somehow join the party. Therefore 2/3 for me...
<ChessHigherCat: That made me think the "quiet move" must be it, so I played 28. Nf4 Nxf6 29. Nxg6 Nxh5 30. Ne7+ Kh8 31. Rg8+ Qxg8 32. Rxg8#>: what if black doesn't capture the queen on move 29? Say 29. ... Rg7 30. Nxf8 Nxh5. Wouldn't this lead to an equal game? |

| Jul-20-22 | | boringplayer: I always appreciate your insights, TheaN. |
|
| Jul-20-22 | | agb2002: The first ideas that come to mind are Rxg6+ and Nf4. In the case of 28.Rxg6+ hxg6 29.Rxg6+ Rg7 30.fxg7: A) 30... Rxg7 31.Rh6 Rg5 32.Rh8+ Kg7 33.Qh7#.
B) 30... Qf2 31.Qh8+ Kf7 32.Qf8#.
-----
This is far quicker than 28.Nf4:
A) 28... b3 29.Nxg6 bxc2+ 30.Kc1 hxg6 (30... Qe8 31.Ne7+ Kh8 [31... Kf8 32.Rg8#] 32.Rg8+ Qxg8 33.Rxg8#) 31.Rxg6+ Rg7 32.Rxg7+ Rxg7 33.Rxg7+ wins decisive material. B) 28... Nxf6 29.Nxg6
B.1) 29... Nxh5 30.Ne7+ Kh8 31.Rg8+ Qxg8 32.Rxg8#. B.2) 29... Rg7 30.exf6 (30.Nxf8 Nxh5) 30... Qxf6 31.Ne5 wins decisive material. |
|
| Jul-20-22 | | Granny O Doul: @AIC: On 29....Rg7 there, White's best is probably 30. exf6 Qxf6 31. Ne5 with an extra piece and total domination. |
|
| Jul-20-22 | | mel gibson: I considered the text move straight away but I couldn't see how I could checkmate the black King. I then thought 28. Nf4 to bring another attacker into play.
I checked on Stockfish 15 and my move still wins with a score of -9.0 for Black. However Stockfish 15 follows the text and says mate in 29: 28. Rxg6+
(28. Rxg6+ (♖g2xg6+ h7xg6 ♖g1xg6+ ♖f7-g7 f6xg7

score for White _ mate in 29. |

| Jul-20-22 | | ChessHigherCat: <Granny O Doul> and <AIC>: Thanks a lot for your feedback. I took it for granted that black would snarf up to the queen because that's what all my fellow blitzers would have done when I used to play speed chess in the park, where nobody has the time to look a gift queen in the mouth. Anyway, thanks AIC for pointing out my over-hasty assumption and thanks to Granny for saving our line's honor: I'm too tired to commit seppuku at this juncture :-) . |

| Jul-20-22 | | Skewbrow: Can someone with more imagination explain to me, if there is something decisive for white after 28. Rxg6+ Kh8? Sure white is a pawn up, and h7 is then pinned, but I don't see much anything. The first follow up I looked at was 29. Qh6, but it doesn't really threaten anything. |
|
| Jul-20-22 | | unferth: <Skewbrow> Nf4 and I think black's helpless against threats of Rh6 and Ng6 |

 | | Dionysius1: It came down to counting exchanges on g7 for me. I'm not good at that (particularly, incidentally, when the the exchanges are of mixed values). So I was glad to find Rh6 at the end of it. I decided if I'd miscalculated with 28.Rxg6 then 28.Nf4 looked good. |
|
| Jul-20-22 | | beenthere240: 27. Ne2 was a crucial move to guard whites back rank. |

| Jul-20-22 | | thegoodanarchist: Kengis Gone. |
|
| Jul-20-22 | | TheaN: <unferth: <Skewbrow> Nf4 and I think black's helpless against threats of Rh6 and Ng6> I had Rg8+ as followup, but Rh6 and Qg4 are more clinical. It's interesting, because normally it depends on what Black does, but Black can barely do anything thus the followups are the same!

The queen's defending against mate on g8, the rooks are defending g7 and the bishop's defending e6 (Bb7 Bxe6! +-). So that leaves a knight or pawn move, but they're all pointless. SF gives 29....Nc3+?! but that's just to prevent mate, 30.Ka1 Nd2 31.Nxd2 #8 to divert the knight away from f4. Lets waste a move with <29....a5> (pressure the queen side?). After 29....b3 White has the simple 30.axb3 to stop threats if he wants to so that is a bit pointless. Now we see the clinical finish: 30.Qg4! bxc2+ 31.Kc1 Nxf6 32.exf6 hxg6 33.Nxg6+ #6 and Black will get mated soon. . 30.Rh6! is indeed also #8. In comparison, 30.Rg8+?! Qxg8 is +10 or so after 31.Rxg8+ +-, which is even better than 31.Ng6+ +- but both win. Black simply can't coordinate his pieces. |

| Jul-20-22 | | jes47: I prefer 29. Nf4, and now black doesn't have better than 29. ... Nf6 30. Ng6 Nh5 31. Ne7++ and mate in two. Faster and prettier. |

| Jul-20-22 | | TheaN: <jes47: I prefer 29. Nf4, and now black doesn't have better than 29. ... Nf6 30. Ng6 Nh5 31. Ne7++ and mate in two. Faster and prettier.> 29.Nf4 Nxf6 30.Nxg6 Rg7 is far from pretty for Black but White still has to be careful, regardless, Nf4 is not faster than Rxg6+. |
|
| Jul-20-22 | | catlover: This is a pretty good puzzle. I feel accomplished in having seen the two main options, 28 Rxg6+ and 28 Nf4. Unfortunately, it was beyond my skill level to visualize how both moves could play out to a win, with all the variations. I appreciate all the variations and comments of my fellow kibitzers. In a game, I probably would have gone with 28 Nf4. |

| Jul-21-22 | | TheaN: <TheaN: <jes47: I prefer 29. Nf4, and now black doesn't have better than 29. ... Nf6 30. Ng6 Nh5 31. Ne7++ and mate in two. Faster and prettier.> 29.Nf4 Nxf6 30.Nxg6 Rg7 is far from pretty for Black but White still has to be careful, regardless, Nf4 is not faster than Rxg6+.> Actually correcting myself, jes I reckon you did mean 28.Nf4 and not 29.Nf4?. The latter is a blunder, as 29....Nxf6 equalizes. 30.Nxg6? Nxh5 -+ just throws the queen as Ne7+ is not mate. |
