Kibitzer's Corner
Dec-12-20  The17thPawn: After 22.) ...,Kf8 23.Rg3,Qxg3 24. hxg3 black is in a bad way.
Dec-12-20  The17thPawn: Perhaps giving up the rook entirely is the better course but not a position I'd want to defend.
Dec-12-20  Walter Glattke: I found with view at the first website 17.Nf6+ Kh8 or 17.-gxf6 18.Qg4+ Kh8 19.Qh5 f5 20.Qxh6+ Kg8 21,Re3 f6 22.Rg3+ Kf7? 23.Rg7+ Ke8 24.Rxc7, so 23.-Qxg3 24,fxg3 (not hxg3 by Rh8) 17.-Kh8 18.Qh5 Qf4 19.Nh7 Re8 20.Re3 or 19.-Rd8 20.Re3 f5 21.Rg3 Rg8 22.Qg6 Bb7 23.Ng5! QxR & hxN, then 25.Qh5#

They played 17.Nf6+ Kh8 18.Qg4 gxf6 19.Re3 Rg8 20.Qh4 Rg7 (20.-Kg7 21.Rg3+ Kf8 22.Qxh6+ Ke7 23.Rxg8 Bb7 24.Rxa8 Bxa8 25.h4) 21.Qxh6+ Kg9 22.Rh3 resigned, 23.-Kf8 24.Qh8+ Ke7 25.Qxg7 Bb7 26.Rh7 Nd8 27.Bg6 f5 28.Bxf7 Qxc2 29.Be8+ Kd6 30.Qd7+ Ke5 no forced mate then.

Dec-12-20  Walter Glattke: 17thpawn after 22.-Kf8 23.Rg3 not QxR,, 23.-Ke7 then.
Dec-12-20  The17thPawn: < Walter Glatke> - Precisely, but it doesn't look an enviable task as black.
Dec-12-20  scormus: 17. Nf6+ was easy enough to find. After that the biggest difficulty is trying to decide what B is going to play. I was looking at 17 ... gxf6 18 Qg4+ Kh8 whch might not be the best. But since B played it next move it transposed to that anyway.

The engine suggests that 18 ... Rg8 19 Qe4 g6 as the best defence but W still has all the play (+2.0).

After 18 ... gxf6 19 Re3, .... f5 loooks like the best try, blocking the diagonal. Then 20 Qh4 Kg7 21 Rg3+ Qxg3 22 Qxg3+ Kh7 and W has Q for R+N. B can fight on for a while but the W keeps a strong initiative and is easily winning (+3.0).

Dec-12-20  Brenin: 17 Nf6+ is obvious, as 17 ... gxf6 18 Qg4+ Kh8 19 Re3 is hopeless for Black. If the N sac is declined with 17 ... Kh8 then 18 Qg4 leaves Black with a wide choice of roads to perdition, and he chose an easy one with 18 ... gxf6, no better now than it was a move back. He might have tried 18 ... Ne7 with interesting complications, e.g. 19 Qe4 Ng6 20 Qxa8 Bb7 21 Qxa7 Ra8 22 Ne8 Qc6 23 Be4 Rxa7 24 Bxc6 Bxc6 25 Nd6. This line loses the exchange, but it gives White a chance to make a mistake, whereas the line played was fatal.
Dec-12-20  Walter Glattke: 18.Qg4 gxf6? 18.-Ne5, in my line above I play Qh5 to attack Pf7 and Ph6 occasionally. 18.-Ne5 19.Rxe5? Qxe5 / 19.Qe4 g6 20.Qxa8 Kg7
21.Qe4 (21.Ne4 Bb7 22.Qxa7 Ra8) oe 21.Nh5+ gxh5 22.Qe4 Nxd3 or 22.-f5
Dec-12-20  pcarpane: How about 18 ... e5?
Dec-12-20  Brenin: <pcarpane>: After 17 Nf6+ Kh8 18 Qg4, 18 ... e5 loses to 19 Qe4 g6 (otherwise mate on h7) 20 b5, winning the pinned N or the R on a8. Black needed to play Bb7 before castling, to prevent this sort of threat.

  agb2002: The queen has free access to the king side and the rook on e1 can reach the third rank at once. These details suggest 17.Nf6+:

A) 17... gxf6 18.Qg4+ Kh8 19.Re3 (19.Qh4 Kg7 20.Re3 Rh8 21.Rg3+ Kf8 22.Qxf6 Qe5 -22... Rg8 23.Qxh6+ and 24.Rxg8 wins decisive material- 23.Qf3, unclear)

A.1) 19... Ne5 20.Qf4

A.1.a) 20... Kg7 21.Rg3+ wins (21... Kh8 22.Qxh6#; 21... Ng6 22.Qxc7).

A.1.b) 20... f5 21.Qxh6+ Kg8 22.Rh3 f6 23.Qh8+ Kf7 24.Qh7+ Ke8 25.Qxc7 wins.

A.2) 19... f5 20.Qh4

A.2.a) 24... Kh7 25.Rh3 f6 26.Qxh6+ Kg8 27.Qh8+ as in A.1.b.

A.2.b) 24... Kg7 25.Rg3+ Qxg3 (25... Kh7 26.Rh3 transposes to A.2.a) 25.Qxg3+ and 26.Qd6 wins decisive material.

A.3) 19... Rg8 20.Qh4 Rg6 (20... Kg7 21.Rg3+ Qxg3 -21... Kf8 22.Qxh6+ wins decisive material- 22.Qxg3+ as above) 21.Bxg6 fxg6 22.Qxh6+ Kg8 (22... Qh7 23.Qf8+ Qg8 24.Rh3#) 23.Qxg6+ Kf8 (23... Qg7 24.Qe8+ wins decisive material) 24.Qxf6+, with the exchange and three pawns for both pieces and attack, looks winning.

B) 17... Kh8 19.Qh5 with attack (Re3-g(h)3 and Ng4-xh6).

Dec-12-20  cormier: 6... Qb6 better is 6...b6 7.Be2 Bb7 8.Qd3 Nc6 9.O-O-O Ne7 10.Kb1 h6 ⩲ +0.62 (17 ply) 7. Rb1 ⩲ +1.29 (17 ply)

  drollere: as others comment, Nf6+ was the obvious way to crack open the Kside, but like others i assumed W would respond with pxf6. the game transposes into this position on the next move, but also gifts white a tempo.
Dec-12-20  Brenin: <agb2002>: In your line (B), after 17 Nf6+ Kh8, 18 Qh5 doesn't threaten much, and can be answered with the unlikely-looking 18 ... Nxb4, since 19 Rxb4 allows the triple fork (and mating threat) 19 ... Qc3. If 19 Be4 (preserving the powerful B) then Black can safely return the P with 19 ... Nd5 20 Nxd5 exd5 21 Bxd5 Bb7. I think the Q has to go to g4 or f3 on move 18.
Dec-12-20  morfishine: <scormus> Well said
Dec-12-20  pcarpane: Thanks <brenin>. I didn't see the pin. And maybe 20 ... Bf5 removing the knight?
Dec-12-20  devere: Black can put up as better fight with 18...Bb7, but after 19. Qe4 g6 20. Qe3 Kg7 21. Ng4 Rh8 22. b5 Ne7 23. Qd4+ White still has a winning attack.
Dec-12-20  Brenin: <pcarpane>: After 17 Nf6+ Kh8 18 Qg4 e5 19 Qe4 g6 (otherwise mate on h7) 20 b5 Bf5, White simply plays 21 Qxc6, winning the N, or 21 Qh4 forcing Kg7 or h5, and then 22 Bxf5. Either way White wins a piece.

<devere>: Your line has a nice continuation 23 ... Kg8 (23 ... e5 26 Rxe5) 24 Nf6+ Kf8 25 Ne8 Rxe8 26 Qxh8+ Ng8. Black has survived, but he is the exchange down with a very inferior position.

My first idea was 18.Qg4 (18... gxf6 would then transpose) but had the impression that Qh5 was somewhat stronger.
