| Apr-18-17 | | stst: Black K is imprisoned. R-sac first, then make Q dropping down for kill.
28.Rg3+ N takes or not...
(A)If N takes R
29.Qg4+ no defense for Qg7#
(B)If N not taking R, K hides Kf8
29.Bg7+ Kg8
30.Bf6 dis+ NxR ===> Black Q lost (BxQ) |
|
| Apr-18-17 | | Walter Glattke: Black is a knight ahead, 28.Rg3+ Qg5
29.Rxg5+ Kf8 - later mate!? |
|
| Apr-18-17 | | AlicesKnight: 28.Rg3+ is good. If Black takes, then 29.Qg4+ leads to mate on g7. If he declines with ...Kf8, then 29.Bg7+ leads to something similar, or perhaps loss of the Black Q. 24...g6 was ineffective and weakening. |
|
| Apr-18-17 | | Gilmoy: Kupreichik approves of <25.Ndf5> to deflect g open! It's the proper use of a Knight ... White's opening seems fun: give Black space, open lines, the bishop pair, and enough time to outsmart himself. There's a method to it: he saddles Black with the IQP, then promptly blockades it while Bb2 percolates. <14..Ne5 15.f4> might not be an error by Black, although it does allow White to deny Be5 defenses, and with tempo. Maybe at this point White started seriously calculating the K-side attack with double-Nf5. |

 | | agb2002: White has a pawn for a knight.
The prosaic 28.Qg4+ is met with 28... Q(N)g5 (the black bishop pins the pawn on f4). Therefore, 28.Rg3+: A) 28... Nxg3 29.Qg4+ and mate in four.
B) 28... Kf8 29.Bg7+ Kg8 30.Bf6+ wins decisive material. C) 28... Ng5 29.Rxg5+ Kf8 30.Bg7+ Kg8 31.Bf6+ Kf8 32.Rg8+ and mate in two. D) 28... Qg5 29.Rxg5+ wins. |

| Apr-18-17 | | Mendrys: 21. Rf3 seems like a very prescient move, but given the weakness of the e pawn it's not really that hard to consider. If some other playable move were played, 21. Rce1 or the weird 21. Ba1 for instance, and the rest of the game played out similarly then 27... Ne4 would be winning for black. It's a good thing for us, however, that the text move was played. 28. Rg3 is a pretty move to see. |

B) 28... Kf8 29.Bg7+ Kg8 30.Bf6+ wins decisive material.> Excellent analysis as always, my friend. I think we can go a little further than winning material in this line. After 30. Bf6+ Kf8 we arrive here:

| Apr-18-17 | | hudapri: What Ashot! |
|
| Apr-18-17 | | Cheapo by the Dozen: Nice diversion. White has two ways to check on the g-file; Black has one defender; using the defender against the first attacker makes it unavailable against the second. |

 | | thegoodanarchist: I found 28.Rg3+ Nxg3 29.Qg4+... and rejected the line! What a maroon. Seems like I forgot what day it is. |

 | | gawain: 28 Rg3+ Nxg3 29 Qg4+ and mate soon. And if Black declines the rook 28 ... Kf8 then 29 Bg7+ wins. (I thought it only wins the queen but with the help of my fellow kibitzers I see it also leads to a quick mate.) |
|
| Apr-18-17 | | BOSTER: <Gilmoy:enough time to outsmart himself>.
After 25.Ndf5 gxf5 26.Nxf5
black could play 26...Ng4+ and if 27. hxg4 Qe4 , and black is better. |

 | | ChessHigherCat: The N on d5 is a sub-royal pain in the neck. The first thing that comes to mind is 28. Qxd5, but then Qxd5 29. Rg3 Qg6 and white is foiled again. If 28. Qg4+ then black can block and offer a trade with Qg5 because the f pawn is pinned. That leaves 28. Rg3+ Nxg3 29. Qg4+ and now it works (tadaa!) |

| | ChessHigherCat: [Corrected, expurgated version with an introduction by Mr. Peabody, all rights reserved): The N on d4 is a sub-royal pain in the neck. The first thing that comes to mind is 28. Qxd4, but then Qxd4 29. Rg3 Qg6 and white is foiled again. If 28. Qg4+ then black can block and offer a trade with Qg5 because the f pawn is pinned. That leaves 28. Rg3+ Nxg3 29. Qg4+ and now it works (tadaa!) |
|
| Apr-18-17 | | JohnDMaster: Thank you Once, I was waiting for someone to point out that Rg3 leads to forced mate in all lines including the queen block on g5! |
|
| Apr-18-17 | | morfishine: <whiteshark> Yes, this was easy, but its only Tuesday; and now headed into, for me, the dreaded Wednesday problem: For some reason, Wednesday mediums gives me more problems than Thursday mediums ***** |

 | | drollere: the obvious check Qg4+ can be blocked by the N at g5, supported by the Q (the p at f4 is pinned). Rg3+ either draws off the N (Nxg3, Qg4+ and Qg7#) or (if Kf8) prepares Bg7+ and Bf6+, winning the Q. |

Excellent analysis as always, my friend.> Thank you!
<I think we can go a little further than winning material in this line.> I noticed that when writing my line C but forgot or overlooked to revise my line B. |
|
| Apr-19-17 | | morfishine: <agb2002> You are an inspiration! Maybe I will return to posting more detailed analysis, like I did in the old days best, morf
