 | | perfidious: The deflexion 31.Rxh5 leaves the Black king nekkid as a jaybird before the opposing hordes. |
|
| Jun-29-22 | | Brenin: After 17 ... Bxc3? 18 bxc3 White had a strong attack, and the R sac 27 Rxg6 would make a good Saturday or Sunday POTD. However, 30 Bd2 was a mistake (30 Be2 was better, threatening Bc4+): it allowed the defence 30 ... Qc8, forcing White to find a further R sac 31 Rxf6+ to continue the attack; if 31 ... Nxf6 (or Kxf6 32 e5+) then 32 Rxh7+ Nxh7 (Rxh7 33 Qxc8) 33 Qh5+, and White's Q+2B cut Black to pieces. |

| Jun-29-22 | | ChessHigherCat: I wasted a lot of time trying to figure out what could possibly be wrong with Rxh5, and answer came there none. Rxh5 Rxh5 Rg7+ and the King has a grand total of two squares, f8 or e8. If Ke8. Qg6+ mates faster than a West Virginian floozy, and Kf8 ain't much better. |

| Jun-29-22 | | EasilyConfused: @Brenin: if 35..Kxe7, I don�t see a fast win for White |
|
| Jun-29-22 | | ChessHigherCat: For the pun, Byrne baby cramer! (French slang for " to burn") almost works, but unfortunately it's pronounced "craw-may" instead of like Kramer. My second important point is that I tactfully refrained from writing Kf(ornic)8. |

| Jun-29-22 | | agb2002: White has the bishop pair for both knights.
The knight on h5 and the rook on h7 protect g7. This suggests 31.Rxh5: A) 31... Rxh5 32.Rg7+ Kf8 (32... Ke8 33.Qg6+ Kf8 34.Qf7#) 33.Qg6 A.1) 33... Qe8 34.Qxf6+ Qf7 35.Qxf7#.
A.2) 33... Qd7 34.Qxf6+ Ke8 35.Bxh5+ wins (35... Rxh5 36.Rg8#). A.3) 33... Rxh2+ 34.Kg1 Qd7 35.Qxf6+ Ke8 36.Rxd7, followed by Qxd4, wins decisive material. B) 31... Nd3 32.Rxh7+ Rxh7 33.Qf5
B.1) 33... Nxf2+ 34.Kg2 Nd3 35.Bh5 is winning.
B.2) 33... Ne5 34.Bh5 Rxh5 (34... Nxg6 35.Bxg6+ and 36.Bxh7 wins two pieces) 35.Qxh5 Nxg6 36.Qh7+ and 37.Qxg6 wins a piece. |

| Jun-29-22 | | newzild: <EasilyConfused> White has a decisive material advantage and can get to work on loose pawns with 36. Bb4 b6 37. Qg7+, etc. |
|
| Jun-29-22 | | saturn2: The game move came qickly. 31.Rxh5 Rxh5 32. Rg7 Qf8 33.Qg6 threatens Qf7 and Bxh5 and if Rxh2+ then 34.Kg1 Qe8 and 35.Qxf6 Afterwards I saw 31.Qf5 is also strong and wins a piece. The engine recommends ...Qd7 I expected Nd7 |
|
| Jun-29-22 | | Brenin: <EasilyConfused: @Brenin: if 35..Kxe7, I don�t see a fast win for White>The win is not fast, but it is ievitable and fairly straightforward. After 33 ... Qe7 34 Rxe7 Rxh2+ 35 Kg1 Kxe7 36 Qg7+ (<newzild>'s 36 Bb4 b6 37 Qg7+ is also strong) Ke8 (Ke6 38 Bg4+ with mate in a few moves) 38 Qxf6, and Black's K has nowhere to hide from the checks by White's Q+2B. Eventually White can drive the K onto the b8-h2 diagonal and then win the R on h2 with Bf4+. |
|
| Jun-29-22 | | Lambda: There's a closely balanced question here whether it's legitimate to assume that the position after 33...Rxh2+ 34.Kg1 Qe7 35.Rxe7 Kxe7 is a win based on the material balance and the exposed black king, or whether you need to calculate further. |

| Jun-29-22 | | goodevans: I misread 'D Byrne vs G Kramer' on the home page and just for a second I thought it might be <David Byrne vs Kelsey Grammer>. Doh! |
|
| Jun-29-22 | | TheaN: <31.Rxh5 Rxh5 32.Rg7+ Kf8> was kind of obvious, but the silent move <33.Qg6!> took me a while, considering it allows <33....Rxh2+>. That's not a problem after <34.Kg1>, and Black still has to deal with the mate threat. Qe8 35.Qxf6+ #1 doesn't work, nor that any other defense that neglects f6 or f7, so that really leaves <34....Qe7 35.Rxe7 Kxe7>:
click for larger view<Lambda: There's a closely balanced question here whether it's legitimate to assume that the position is a win based on the material balance and the exposed black king, or whether you need to calculate further.> At least acknowledging that Black has this defense is key, then a quick glance is needed to see that Black's doubled rooks hamper him more than it does good as it limits options. <36.Qg7+ Ke8 37.Bf4 +-> for example, blocking off many squares around his king, and White can slowly bring the bishops into the attack. |
|
| Jun-29-22 | | Cellist: I saw the first two moves quickly but then was struck by chess blindness and overlooked Qg6. I therefore wanted to play 31.e5 to open space for the white-squared bishop. This does give White an advantage (+1.61), but not a clear one. |

Better than RxQ after Qe7
33...Qe7 34. Bxh5
..Qxg7 35. Qe8# or
..Rxh5 35.Rf8# |

Oof that's a 30 points difference (+15 to -15) from one move, as after 34.Bxh5?? Qxg7 -+, the White queen's pinned :> |
|
| Jul-01-22 | | TheaN: Or well, <33>....Qe7 34.Bxh5 +- sure, but of course Black should zwischenzug 33....Rxh2+ 34.Kg1, which I did, and then the queen's pinned after 34....Qe7 35.Bh5?? Qxg7 -+. |
