 | | al wazir: I actually considered the game line, but I went with 28...Nxh4 29. Bxe4+ Qxe4+ 30. Kh2 Qxc2+ 31. Kg1 Rxf4 32. gxh4 (32. gxf4/Qxf4 Qg2#) Qf2+ 33. Kh1 g3. I think that's a win. |
|
Dec-13-20
 | | drollere: why isn't Nxh4 with threat of Bxg2+ the better way? i don't get it. |

 | | beatgiant: I think the answer to <why not 28...Nxh4> is simply 28...Nxh4 <29. gxh4> Qxh4+ 30. Kg1. White's attacking the rook on f8, and I'm not seeing Black's follow-up. |

White's attacking the rook on f8, and I'm not seeing Black's follow-up.> I agree, after 28...Nxh4 there is no very good continuation for Black, regardless of the fate of the Bishop on g2. 28...Nxh4 29. gxh4 Bxg2+ 30. Kxg2 Qe4+ is not immediately won, and 28...Nxh4 29. gxh4 Bxg2+ 30. Nxg2 Rf2 must be defendable. I pondered on tricks around 28...Nxh4 29. gxh4 Ka7 or 29...Bxg2+ and then Ka7, with the intention of bringing the Queen on b7, but never really seems to work. The immediate 28...Rxf4 has no positive effect, sadly. |

| Dec-13-20 | | Brenin: Does Black have anything after 34 Kg3, other than loss of the B or N? After an imaginative attack, he seems to lose the thread with 32 ... Bf3 (Bc6 safer?) and 33 ... Qd7 (better Qe3, e.g. 34 Qxh4 Qe2+, with mate). |
|
| Dec-13-20 | | ChessEagle: Great! |
|
| Dec-13-20 | | Brenin: <Walter Glattke>: I'm afraid that 28 ... Nxh4 (not h5) 29 gxh4 Qxh4+ 30 Kg1 g3 loses to 31 Bxe4+, with mate to follow, e.g. 31 ... Ka7 32 Qg7+ Kb6 33 Qb7+ Ka5 34 axb4# |
|
| Dec-13-20 | | Walter Glattke: Ok, that check spoils my morning comment, I try 29.-Bxg2+ 30.Nxg2 g3 31.Re1 Qd7, otherwise one must follow the match continuations with not 28.-Nxh4. For less strong kibitzers: 32.Qe6 Qxe6 33.Rxe6 Rf1# 32.Kg1 Qh3 33.Qg7+ Kb6 34.Qxf8!? Qh2+ 35.Kf1 Qh1# |

Out of sheer curiosity I said to our digital friend let's look at the original position (that was a bad idea - I had to figure out myself where Black went wrong - i.e. to allow Kg3 - but I was lazy). The result is

WARNING: blindly trusting an engine output is equally wrong for amateurs and grandmasters. Use the copypasted results with caution, calculate stuff yourself, if you want insights. |

| Dec-13-20 | | morfishine: <28...Rxf4> was all I considered |
|
| Dec-13-20 | | Walter Glattke: But 32.Qxf8 Qh3+ 33.Kg1 Qh2+ 34.Qf1 Qh1+ 35.Ke2 Qxg2+ maybe 31.-Qf7 32.Nf4 Qxf4 with little black advantage. |
|
| Dec-13-20 | | awfulhangover: Uff, too difficult. |

| Dec-13-20 | | landshark: Today I can't hack it because the board doesn't stay still once I've delved into the real game and am trying to look at it after the first move of the puzzle sequence - F--k this!!!!
CG you need to do <at least something> about the adds jumping all around the site and flashing, etc, if you want to keep your viewers. |

| | Yuridmi: Looks like White's 28. a3 is a disaster. The fight is on the Kingside, with immediate action required.
White can stay in the game with either 28. Rd1 or 28. Qe6 |
|
| Dec-13-20 | | Brenin: Many thanks, <Messiah>, for that analysis of 34 Kg3 Qd2. Some of those moves are hard for mere carbon-based life-form like me to understand, e.g. having driven Black's K into the a8 corner and protected the Ps on c2 and f4 with Qc7, why play a4 when axb4, opening up the a-file and threatening mate on a6, is possible, or why not take the hanging N with Kxh4? But who am I to argue with something called <info depth 50 seldepth 47 multipv 1 score cp 0 nodes 2868072580 nps 3367306 hashfull 945 tbhits 23892830 time 851741 pv>? Whatever, this confirms my impression that White could have had at least a draw with 34 Kg3. |

 | | agb2002: White threatens Nxh5, Qxh5, and axb4-Qxa6+.
Black's pieces look ready to attack the white king. White's g-pawn becomes overburdened after 28... Rf6: A) 29.Qxh5 Rxf4 30.gxf4 Nxh4 31.Rg1 (31.Bxe4 Qxe4+ 32.Kg1(h2) Qg2#) 31... Bxg2+ A.1) 32.Rxg2 Qe1+ 33.Rg1 (33.Kh2 Nf3#) 33... Qe4+ 34.Kh2 Qxf4+ 35.Rg3 (35.Kh1 Qf3+ 36.Kh2 Qh3#) 35... Qf2+ 36.Kh1 Qxg3 A.1.a) 37.Qf7+ Qc7 is winning (38.Qd5+ Qc6).
A.1.b) 37.Qh7+ Kb6 38.Qh6+ Kb5 39.c4+ (39.a4+ Ka5 -39... Kxa4 40.Qxa6#-) 39... bxc3 40.a4+ Ka5 is winning. A.1.c) 37.Qd5+ Kb6 38.Qe6+ Kb5 39.c4+ (39.a4+ Ka5; 39.Qd7+ Kc4) 39... Ka5 40.axb4+ Kxb4 41.Qb6+ Kxc4 42.Qxa6+ Kd4 looks winning. A.2) 32.Kh2 Bf3 looks very good for Black.
B) 29.Qh8 Rxf4 is winning (30.gxf4 Qxh4+ 31.Bh3 Qxh3#). The alternative 28... Nxh4 29.gxh4 doesn't seem to achieve much after either 29... Qxh4+ 30.Kg1 or 29... Bxg2+ 30.Nxg2 (30.Kxg2 Qe4+ 31.Kg3 Qf3+ 32.Kh2 g3+ 33.Kh3 (33.Kg1 Qf2+ 34.Kh1 Qh2#) 33... Qg4+ 34.Kg2 Rxf4 is winning). |

| | agb2002: I missed a mate in few moves in my line A.1: 35... Nf3+ followed by Qc1+ or Qd2+. |

| | drollere: <landshark: Today I can't hack it> this isn't too helpful. email <chess@Chessgames.com> and specify your operating system and version, browser and version, and if possible a screen shot of the problem and a description of when (how) the problem occurs. for example, ads do not jump all around a "site". a "site" is a server with an IP address. the ads jump around in browser windows, depending on when and how you upload or interact with a web page. |

| Dec-13-20 | | olinart: I thought Nxh4 wins:
28. .. Nxh4 29. gxh4 Bxg2+ 30. Kxg2 Qe4+ 31. Kg3 Qf3+3 2. Kh2 Rxf4 gives black a winning attack.
but
31. Nxg2 Qf2+ 32. Kh1 g3 33. Rg1 Rf5 34. Qh7+ Rf7
35. Qxh5
seems to defend for white. |
|
Dec-13-20
| | al wazir: <beatgiant: I think the answer to <why not 28...Nxh4> is simply 28...Nxh4 <29. gxh4> Qxh4+ 30. Kg1.> Yes, you're right. I realized that after I posted. |
