 | | fredthebear: 29.Nh7! FTB does not recall seeing this stunt before. It serves as a decoy sacrifice. White ends up with an equal exchange sequence: N, R, P for the Black Q. However, it's White that gets the e7 entry square, maintains the initiative, and the central Black pawns fall off. This gives White connected passers. |

 | | al wazir: My move was 29. Re7. If 29...Qxf6 , then 30. Rf7, and black has nothing better than 30...Qxf7 31. Nxf7 Kxf7 32. Qxh6. Now white has ♕+♙ vs. ♖+♘ If 32...Rh8, then 33. Qg5 Bxh3 34. Qxc5, and white picks up more material. Not very different from the game line. |

Kg7 30.Re8+ Rxe8 31.fxe8Q Rxe8 -+ B) 29.Re7 Qxf6 30.Rf7 ++- / 29.-h5? 30.Rg7+ Kh8 31.Rh8+ Kg8 32.f7+ queen lose / 29.-hxg5?? 30.Qh7# / 29.-Nd6 30.Nh7 g5 31.Nxg5 Qxf6 Bf5 guards h7 so 31.Nxf8 gxh4 32.Nxd6 Rxd3 33.Nxc5 litttle white advantage - better so far 29.Nh7 in the match |

 | | hoodrobin: Kobalia went down in the opening, then he fought long and hard. |
|
| Apr-01-21 | | Brenin: My idea was 29 Re7, e.g. Qxf6 30 Rf7 Qh8 31 Rh7, but I missed Black wriggling out with 31 ... Nf3+ 32 Rxf3 Qd4+ 33 Kh1 hxg5 34 fxg5 Qxh4 35 Rxh4 Bxd3, giving only a slight advantage to White. |
|
| Apr-01-21 | | AlicesKnight: I went with the line identified earlier by <Jimfromprovidence> when I looked at first. Either way the Pawn clearance and White Ps advance becomes decisive when the Black pieces cannot combine actively. |

| Apr-01-21 | | malt: Looked at 29.Re7, 29,f7+, 29,Nf7
29.Re7 Q:f6 30.Rf7 Qh8 31.Rh7 Qf6 32.Q:h6 B:d3 33.Rb7 Qh8 34.Q:h8+ K:h8 35.Nf7+ 29.f7+ does not look promising.
29.Nf7 h5
(29...Q:f7 30.Re7 Qf8 31.Rg7+ )
30.N:d8 R:d8 31.Re7 Rd7 32.Rfe1 looks OK. |

| Apr-01-21 | | mel gibson: I thought R-e7 and that was a mistake as
the Black Queen takes the f6 pawn.

| Apr-01-21 | | Refused: Meh, just like <Jimfromprovidence> I went with the slightly 29.Nf7 it's still better for white, just not by as much as the game continuation. |
|
| Apr-01-21 | | Refused: <al wazir: My move was 29. Re7. If 29...Qxf6 , then 30. Rf7, and black has nothing better than 30...Qxf7 31. Nxf7 Kxf7 32. Qxh6.> 30...Qh8 looks like an improvement for black there. 31.Rh7 Nf3+! 32.Bxf3 Qd4+ 33.random move hxg5 and black might just survive this. The queen is still covering the vital dark squares and black has managed to trade off two of white's attackers (the pawn on f6 and the N on g5). |
|
| Apr-01-21 | | Cellist: I also went with 29. Re7, expecting to answer 29. ... Qxf6 with 30. Rf7, but 30. ... Qh8 keeps Black in the game. The engine gives White only a small advantage (+0.46) in this scenario. Selecting 30. Rfe1 as the second move, however, gives White a clearer edge (+1.7). I did like 29. Re7 because it makes the N on g5 immune (29. ... hxg5?? 30. Qh7#). |

 | | paulalbert: I rejected Re7 although it was my original idea because it did not seem to work, so looked at Nh7 which seemed to at least accomplish something, but spent a lot of time trying to find a move more immediately decisive. Finally had to look, pleasantly finding that Nh7 was in fact the solution. |

|
| Apr-01-21 | | King.Arthur.Brazil: I would like not to repeat, however, I follow the fellows Jimfrom-some-providence (perhaps, 1 gim can be the best providence, whichever it is), al Wazir, Brenin and Refused (bud, go slowly and she will not refuse... lgs) with 29.Re7. I think that our team has approximately the same level of thinking in chess. We are far from GM, but we can face some defining positions and still find good moves. |

| Apr-01-21 | | TheaN: Woah, list me in the Re7 club, and I'm by far not the only one. In fact, list me in the Re7-Rf7-Rh7-missingNf3+ club :>. It follows a logical principle of trapping. In fact, White does, but a tempo ruins it. <29.Re7!?> is still pretty good <29....Qxf6 30.Rf7?! (Rfe1! ±)> but after this White goes astray because <30....Qh8! 31.Rh7> doesn't work <31....Nf3+!!>.

Darn this is such a nasty move. A fork, so White's forced to capture, 32.Nxf3? Kxh7 ∓ and after 32.R/Bxf3, the Black queen escapes with tempo, so after 32....Qd4+ 33.Kh2 hxg5 ⩲ and White's advantage is surprisingly minimal. Interesting position. |

 | | agb2002: White has an extra pawn.
Black threatens hxg5 and Qxf6.
White has Nh7 and Re7.
In the case of 29.Nh7:
A) 29... Kxh7 30.Re7+
A.1) 30... Kh8 31.Rg7 h5 32.Qg5 Qxg7 33.fxg7+ looks winning. A.2) 30... Kg8 31.Rg7+ as above.
A.3) 30... Qxe7 31.fxe7 as above.
B) 29... Qf7 30.Re7 Qxh7 31.Rxh7 as above.
C) 29... Qd6 30.Re7
C.1) 30... Rd7 31.f7+ Kh8 (31... Kg7 32.f8=Q#; 31... Kxh7 32.f8=Q+ Rxe7 33.Qhxh6#) 32.Qxh6 wins. C.2) 30... Ne2+ 31.Rxe2 g5 (31... Kxh7 32.Re7+ wins decisive material) 32.Qxh6 Rd7 (32... Bxh7 33.Qg7#) 33.Nxg5 wins decisive material. -----
In the case of 29.Re7:
A) 29... Qxf6 30.Rf7 Qh8 31.Rh7 Qxh7 (31... Qf6 32.Qxh6 wins) 32.Nxh7 looks good for White. B) 29... Rd7 30.Nh7
B.1) 30... Qd8 31.f7+
B.1.a) 31... Kxh7 32.f8=Q+ Qxe7 33.Qhxh6#.
B.1.b) 31... Kg7 32.f8=Q#.
B.1.c) 31... Kh8 32.Qf6+ Kxh7 33.f8=N+ Kg8 34.Qg7#. B.2) 30... Qxe7 31.fxe7 Kxh7 32.Re1 Re8 33.Qf6 looks winning. B.3) 30... Rxe7 31.fxe7 (or 31.Nxf8 Rf7 32.Nxg6 Bxg6 33.Qxh6 Bxd3 -33... Rxf6 34.f5- 34.Qg5+) 31... Qf7 32.e8=Q+ followed by 33.Nf6+ wins an exchange at least. -----
I'd play 29.Nh7 since it looks simpler. |
