| Sep-07-19 | | agb2002: Black has a knight and a pawn for a bishop.
Black has several options to destroy the white castle, Nxh2, Nxf2, Ne3 and fxg3. In the case of 28... Nxh2:
A) 29.Nxh2 fxg3
A.1) 30.Nf3 gxf2+ (or 30... g2, winning decisive material) 31.Kxf2 Rg2+ 32.Ke3 Ng4+ 33.Kd3 Qd6+ 34.Bd5 Nf2+ looks winning. A.2) 30.fxg3 Rxg3+ 31.Qxg3 Rxg3+ 32.Kf2 Nxe4+ 33.Rxe4 Rxa3 wins decisive material. B) 29.Kxh2 fxg3+
B.1) 30.fxg3 Rxg3 followed by Qg7 with three pawns for the knight and attack. B.2) 30.Kg1(2) gxf2+ 31.Kxf2 Rg2+ transposes to A.1. B.3) 30.Kh1 g2+ wins decisive material.
B.4) 30.Kh3 gxf2 31.Rxf2 Rg3+ 32.Kh2 Qg7 33.Kh1 (to interpose a piece on h2) 33... Nxe4 looks winning (34.Rxe4 Rg1+ and mate next). |

| Sep-07-19 | | patzer2: Yogi Berra's famous quote "If you come to a fork in the road, take it," describes my quandary in attempting today's Saturday (28...?) puzzle. Because it's a difficult Saturday puzzle, I figured the answer had to be a demolition tactic, involving either 28...Nxh2! or 28...Nxf2. Unfortunately, I took the wrong fork in the road with 28...Nxf2 ⩲ to = (+0.36 @ 36 ply, Stockfish 10) which is at best only good for equality for Black. The only clear, decisive move is the demolition 28...Nxh2! -+ (-5.95 @ 30 ply, Stockfish 10). Alternatively, Black can secure a strong positional advantage with 28...a5 29. Kg2 a4 ∓ (-1.09 @ 30 ply, Stockfish 10), but that passive, second-best attempt leaves the outcome in doubt. Of course, even if you found 28...Nxh2! -+, you still had to figure out the follow-up which is a bit difficult after 30. Qxe5!? That's because Black has only one winning move after 30. Qxe5!? The brilliant, winning follow-up is of course 31...Reg5! -+ (Mate-in-20, Stockfish 10 @ 40 ply). If 31...Qxe5?, White goes up an extra piece for an easy win after 32. Nxe5 +- (+3.66 @ 36 ply, Stockfish 10). If 31...Qg7?, White equalizes with 32. Kh1 = (+0.14 @ 35 ply, Stockfish 10). So 31...Reg5! -+ is an essential follow-up. P.S.: So where did White go wrong? White's clear, losing move was 27. Qc3?, allowing 28...Ndf6! -+ (-3.44 @ 33 ply, Stockfish 10) with a crushing, attacking position. Instead, 27. Qe2 Ndf6 28. Rab1 Qc8 29. Rb3 Qe8 30. Rb7 ⩱ (-0.61 @ 34 ply, Stockfish 10) gives Black drawing chances. Earlier, instead of trying to passively trade down with 26. Qd2 Qc7 ⩱ (-0.57 @ 30 ply, Stockfish 10), White could have held it level by taking the open file with 26. Rab1 (0.00 @ 30 ply, Stockfish 10). |

 | | perfidious: That is one Berra malapropism I had never heard till this moment, but as always, it is vastly amusing, and certainly is a propos in recent months, come to CG puzzles, as we have seen numerous duals (or still worse), as opposed to the normal standard of the line closing the show in one, and only one, way. |

 | | Breunor: Missed again, I also went for Ne3 which is just even. Two other aspects of this game caught my eye. First was black's 14th move; an issue of positional assessment. Two knights and the pawn can take on e5. My instinct was to take with the pawn, so not allow freedom for the white pawn; but (not surprisingly) the computer agrees with the game move - I guess getting mobility for the center black pawns was more important. The second is the totality of black's moves - it just seems like he takes what looks like an even game to totally winning in an effortless sweep of 10 or so moves. The overall vision of these GM's can be even more impressive than their tactical skill! |

| Sep-07-19 | | wtpy: Patzer, Once again I use the wrong fork. Suppose it doesn't matter-- there is no dining on the king with Qg7. I would have absolutely played Nh2 in a speed game, and would like to think after 31 Qe5, I would have found the correct rejoinder, but then I'd like to think a lot of things that probably aren't true. |
|
| Sep-07-19 | | TheaN: The key in this combination is definitely the last move, regardless the demolition itself is blitzable. Black has such an insane control over the position that it must be correct, but <R3g5!> is a move that has all: 1) Threatens the queen for starters.
2) Threatens Rh5 next.
3) Defends Nf6 and Rg5 by revealing the queen to queen pin. 4) The rook's also immune to the knight as this is the only defender of the queen. |
|
| Sep-07-19 | | PhilFeeley: <bcokugras: 30. Rxg1 was better.> For a whole host of reasons, that move doesn't make any sense. Perhaps you mean 30. Rg1, but that's not possible either. 31. Rg1 is possible. Was that it? |
