| Jul-05-23 | | jrredfield: This is a "square resolver" situation where there's a certain number of attackers and defenders of the same square, in this case, g5. If after Rxg5, Black takes the rook with the knight, White still has two attackers on g5, the queen and a bishop. So White will win the square battle. If after 20 Rxg5, Black plays Nxg5, then 21 Bxg5 cannot be answered with 21 ... Qxg5 due to the White queen on d2. So best for Black is 20 ... Kh8. Then
I see perhaps 21 Rg2 Qh4 22 Rh2 Qe7 23 Rg1, but no clear outcome from there as White doesn't yet attain a commanding advantage yet. |
|
| Jul-05-23 | | Brenin: 20 Bxg5 Nxg5 21 Rxg5+ Kh8 doesn't seem at all decisive, whereas 20 Rxg5+ Nxg5 21 Bxg5 Q moves 22 Rg1, or 21 ... Bxh6 22 Bxh6 all look good for White. Of course, Black has 20 ... Rh8, and the R on g5 has to retreat, e.g. Rg2, with again nothing decisive, but I still like White's position. |
|
| Jul-05-23 | | jrredfield: Sorry, when I said 20 Rxg5, I meant 20 Rxg5+. I just checked this with the engine and see that Rxg5+ is 2 to 3 points better than 20 Bxg5. |

 | | An Englishman: Good Evening: Saw 20...Kh8, which looked very good for White, but Black's best chance. The Nc6 proves a surprisingly useful defender, covering d4 and e5. |

 | | GoldenKnight: If 20. ... Kh8, look at 21. Nd5! Black is forced to take the N, leading to a strong attack by White. But I haven't looked at this thoroughly. |
|
| Jul-05-23 | | King.Arthur.Brazil: Well, trying: 20. Bxg5. If then Nxg5 21. Rxg5+ Kf7? 22. Rf1+ Ke8 23. Bh5+ Kd7 24. Rf7 and win the ♕, I love it. But, Black could play 21... Kh8, when 22. Rdg1?? Bxh6 or 22. Rh1?! Qf6... these complements are really bad, so what do White must play? Therefore, it is best to sac the ♖: 20. Rxg5+ Nxg5 21. Bxg5 Qe8 (to let f7 as a escape route) 22. Rg1 Qg6 23. Qd1 and Black position is very bad, e.g. 23... Ne7 24.Bh5 or 23... Bxh6 24. Bxh6 or 23... Kf7 24. Bh5. In the case of 22... Be7 23. Bxe7+ Kh8 24. Rg7 Qe8 25. Bf6 game over. |
|
| Jul-05-23 | | saturn2: Saw white has to start with Rxg5 then Bxg5 follows with tempo attacking the queen and white has time for Rg1. |

 | | perfidious: The actual continuation is straightforward enough, but in my mind, too obliging; while White's position also looks favourable after 20....Kh8, the path to victory is hardly as clear. |
|
| Jul-05-23 | | Cecco: I agree with <Perfidious>. <Mel Gibson>, after 20. Rxg5 Kh8 21. Rg2 the best defense for black seems to be 21. ... Nce5, with which black can defend for a long time, in a situation of material equality. I am not able to judge this position as clearly winning for white without analysis with the help of engines. |
|
| Jul-05-23 | | AlicesKnight: Chose RXg5+ over Bxg5 with advantage to White as the game went, but less if Black declines the offer, as others have said. |
|
| Jul-05-23 | | Socrates2: Not much of a brainer. Rather straightforward. |

| Jul-05-23 | | sfm: The Engine tells us that
7.Be2, Nh6
is OK, position is (+0.5) advantage to White
White prefers
8.g4
and we have this position with Black to move:
click for larger viewCastling now would lose a knight to g5, so to be able to complete his development Black plays 8.-,f6? This is _very_ bad, says the engine - (+1.42) to White now.
While the right move would have scored (-0.36), almost a 2 pawn difference. What was that move?
8.-,Ng8!
getting the night to the healthy square of f6 is worth the "lost" move. |

| Jul-05-23 | | johnnydeep: 23.Be3: nice - a discovered pin of the black queen! |
|
| Jul-05-23 | | agb2002: White is one pawn down.
Black threatens Bxh6.
After 20.Bxg5 Nxg5 21.Rxg5+ Kh8 (21... Kf7 22.Bh5+ Kf6 23.Qf4#) 22.Rdg8 Bxh6 Black wins decisive material. This suggests a change in the move order, 20.Rxg5+: A) 20... Nxg5 21.Bxg5
A.1) 21... Qf7 22.Rg1 Kh8 (22... Qg6 22.Be3; 22... Rd7 23.Bf6+) 23.Bh5 must be winning. For example, 23... Qxh5 24.Bf6+ Bg7 25.Rg7 Rf8 26.Rg5+ wins decisive material. A.2) 21... Qd7 22.Rg1 is similar to A.1.
A.3) 21... Bxh6 22.Bxh7 recovers material while keeping the attack. B) 20... Kh8 21.Rg2 (21.Rdg1 Bxh6) recovers the pawn and looks winning. For example, 21... Qf6 22.Rf1 Qh4 23.Rh2 Qe7 24.Rg1 Nce5 25.Rhg2 Ng6 26.Be3, followed by Bh5, is overwhelming. |

| Jul-05-23 | | Andrew Chapman: <20.Bxg5 Nxg5 21.Rxg5+ Kh8 (21... Kf7 22.Bh5+ Kf6 23.Qf4#) 22.Rdg8 >
22.Rh5 looks better defending the pawn. |
|
| Jul-06-23 | | Brenin: Despite some ugly-looking moves (7 ... h6, 8 ... f6) Black was doing well until 17 ... Rfd8, when h6 or Nce5 would have been sounder. After 20 Rxg5+ Kh8 21 Rg2 Nce5 22 Rdg1 Ng6 23 Bh5 Nfe5 24 Bxg6 hxg6 (Nxg6 25 Bg5) 25 Qd4 Kh7 26 Bxe5 dxe5 27 Qxe5 Bxh6+ 28 Kb1 Black is just about alive, but his e- and g-pawns are vulnerable, and White threatens to switch his Rs to the h-file. |
