| Nov-02-19 | | goodevans: <perfidious: From the diagram posted by <spingo>, 1.f6+ could create a few headaches.> Indeed, but I imagine the 'few obvious moves' <spingo> refers to are 29...Qxe6 30.Nxe6 Kxe6 31.f5+ Ke7 32.e4 so it would be black to move. |

That other inspiration of Magnus Carlsen, his friend Russian dare-devil GM Danill Dubov, annotates his fantastic win against Rasmus Svane at the European Team Championship. Dubov writes, tongue-in-cheek: “It’s my favourite kind of game: two strong players have no idea what is going on and neither do a very big number of so-called experts.” Mikhail Tal would have liked the fireworks! |

| Oct-17-20 | | Granny O Doul: <You're Svane, you probably think this game is about you, you're Svane...> You had one eye in the mirror as you watched yourself schachmatt. |
|
| Oct-17-20 | | Granny O Doul: Oh wait, Svane lost. Let me think on this some more. |
|
| Oct-17-20 | | Granny O Doul: Ok, let's say "you had one eye in the mirror as your rival said 'schachmatt'." |
|
| Oct-17-20 | | Walter Glattke: Black is a rook ahead, and white hunts the black king, so 31.Bxc4+ (31.-Kxc4 32.Rc1+ Kb5 33.Qc6+ Ka6 34.Rc4 Bd7 35.Ra4# or similar) 31.-Ka5 32.Qc6 Bd7 33.Qb7 Bxa3 34.Qa6+ Kb4 35.Qxa3# 32.Qd5+!? c5 33.b4+ Ka4 34.Qc6+ Kxa3 35.Rd1 cxb4 36.Rd3+ b3 37.Rxb3# 32.-Bc5 in the match 33.b4+ Ka4 34.Qc6+ Kxa3 35.Rf2 Bf5+ 36.Kc1 e.g.Bxb4 37.Ra2# they played 34.Qg2 black should play 34.Bf5+ here. |

 | | al wazir: What a combination!
I have to wonder how much of the last 15 or so moves (starting with 22. Rxf7) Dubov saw in advance. |
|
| Oct-17-20 | | Brenin: 31 Bxc4+ was easy to see, but very hard to prove correct; OTB I would have played it and trusted that I would find a good enough follow-up (or that my opponent wouldn't). Up to move 22, looking at the number of sub-optimal moves, and the question marks awarded by Stockfish, you might think that these were two club players, with the advantage regularly changing sides. After the R sac, both players seemed to find the best moves, apart from Black's 29 ... Kc6, after which he was a dead man walking; 29 ... Qxe6 would have left him with 2R+2B vs Q+R and a good chance of survival. The finish by White, with clever non-forcing moves 34 Qg2 and 36 Bb3, was impressive. |
|
| Oct-17-20 | | stacase: I missed 34.Qg2 but even so, it was pretty straight forward, hardly worthy of the "Very Difficult" label. After all, Black was in pretty bad shape. Over the board I might have seen that 34.Bb3+ didn't work, and that White's Queen was under attack and needed to get out of Dodge. |
|
| Oct-17-20 | | Brenin: <Walter Glattke:> I think that your line 31 Bxc4+ Kxc4 32 Rc1+ Kb5 33 Qc6+ Ka6 34 Rc4 is refuted by 34 ... Rxg5, e.g. 35 fxg5 Bf5+ 36 Ka1 Bc2 37 Rxc2 Qe8 and Black's K escapes; instead 32 Qc6+ is needed, leading to mate. Similarly, after 31 ... Ka5 32 Qc6 Black can escape with Qe8 or Qd7, e.g. 33 b4+ Bxb4 34 axb4+ Kxb4 and White's attack is running out of steam; 32 Qd5+, as in the game, is correct. Your suggestion of 34 ... Bf5+ doesn't help Black, since White's 35 Ka2 simply adds another piece to the attack, e.g. 35 ... Bxb4 36 Qc6+ leads to mate. |
|
| Oct-17-20 | | malt: Got stuck on 34.Qc6+, which went Black's way, found 34.Qg2! |
|
| Oct-17-20 | | Cheapo by the Dozen: Like other folks, I saw the first two stages of the puzzle: a. The bishop is poisoned after 31 Bxc4+.
b. The way to enforce b4 is to play 32 Qd5+ and cause Black to mess up his defense of b4 by getting a pinned interposer at c5. Also like other folks, I then missed 34 Qg2.
That said, while the puzzle probably should have started at Move 34, finding Moves 31-33 was fun in itself. |
|
| Oct-17-20 | | Walter Glattke: BRENIN: You descrive not the only possible answers, I am not forced to play that way, that's the difficulty here. 31.-Ka5 32.Qc6 Qd7 (Qe8?) 33.Qa8 c5 34.Ne4 Qb7 wins a piece back by 35.Qxb7 Bxb7 36.Nxd6 Rxd6 37.Bxg8 Rg6, but good ides here. 34.-Rxg5 in first line 35.d5 Bf5 36.Ka2 Bc2 37.b3 Rxd5 38.Qxd5 c5 39.Ra4+ or the third line, there could be played 34.Qg2 Bf5+ 35.Kb2 Bxb4 36.Qc6+ b5, I understand the very good comment, but I only know, that stockfish is better than me, but has more variation to look. |
|
| Oct-17-20 | | vonKrolock: 31.Bxc4+ suggests itself, as Kxc4 32.Qc6+ is mate in a few moves. So 31...Ka5. Now it's harder. |
|
| Oct-17-20 | | username chosen: 31. Bxc4+ Ka5 32. Qd5+ Bc5 33. b4+ Ka4 34. Qc6+ Kxa3 35. Re2 But... 35..., Bf5+ |
|
| Oct-17-20 | | SlowBishop: <Brenin> The game is so complex that Stockfish analysis shouldn't be trusted. Due to variable calculation depth Stockfish contradicts himself.
For instance, Stockfish marks 15. Bg2 as a mistake, suggesting improvement 15. dxe5 with estimation +2.55, while after the best moves 15... exf4 16. gxf4 Stockfish estimation is +3.45. This means that actually correct estimation after 15. Bg2, as well as after 15. Bg2 exf4 is +3.45, which is higher than estimation of 15. dxe5, so 15. Bg2 is actually the best move in the position. Even more funny than Stockfish blames 22. Rxf7 as a mistake, estimating position after obvious reply 22... Rxf7 as -0.44 and proposes "improvement" 22. Bxd5 with estimation -1.21 Also interesting, that Stockfish says that instead of 29. Bxe6+ better was to make a perpetual check. But in his own analysis, after black's best move 29... Qxe6 white are better. Summarizing, the question marks given by Stockfish to white's moves 15, 19, 20, 21 and 22 as well as to black's moves 17 and 18 are incorrect. |

 | | agb2002: White has a knight for a rook and a bishop.
Black threatens Bxe6.
The position of the black king invites to play 31.Bxc4+: A) 31... Kxc4 32.Qc6+ Bc5 (else 33.Qc2#) 33.Rc1+ Kd3 (33... Kb3 34.Rc3#) 34.Rc3+ Kd(e)2 35.Qg2+ Kd(e)1 36.Rc1#. B) 31... Ka4 32.Qc6+ and mate next.
C) 31... Ka5 32.Qd5+
C.1) 32... Bc5 33.b4+ Ka4 34.Qc6+ Kxa3 35.bxc5
C.1.a) 35... Bd7 36.Qg2 looks winning (36... bxc5 37.Qb2+ Ka4 38.Kc2 Ka5 39.Ra1+ Ba4 40.Qb5#). C.1.b) 35... Qd7 36.Qg2 as above.
C.2) 32... c5 33.b4+ Ka4 34.Ka2
C.1.a) 34... Bd7 35.dxc5 Bg4 (due to Qd1#) 36.Qc6+ b5 37.Qxb5#. C.1.b) 34... Qd7 35.Bb3+ Kb5 36.Qc4+ Kc6 37.Ba4+ Kc7 38.Bxd7 Bxd7 39.Rg1 wins decisive material. C.3) 32... <else> 33.Qb5#. |
|
| Oct-17-20 | | Predrag3141: The hardest move to see in the puzzle position before move 31 was 34 Qg2. I was planning 34 Qc6+, but that is only equal according to Stockfish. The point of 34 Qg2 was to force Black to move his c5 bishop, opening the c-file to allow 37 Qc1+. Since my plan led to equality, no credit for seeing the first few moves. But this qualifies as "insane", not "very difficult". |
|
| Oct-17-20 | | Walter Glattke: I am not sure, but I have no computer, my comment is a second opinion to stockfish, hope that program will not dominate too much this website. |
|
| Oct-17-20 | | dashjon: This is a "Telescope" looking into space and coming up with a mating pattern |
|
| Oct-17-20 | | Brenin: Thanks, <slowbishop>, I agree: my experience in playing through each GOTD over the last few months has been that accompanying Stockfish analysis is often misleading and self-contradictory, and should be taken with a pinch of salt. Indeed my comment, perhaps not as clearly expressed as it should have been, was intended to complain that the analysis gave a misleading impression of the stature of these players. |

| Oct-18-20 | | TheBish: From Dubov's player profile:
<Daniil Dubov became an FM in 2008, an IM in 2010 and a GM on 28 March 2011, aged 14 years 11 months and 14 days. GM Dubov is a rising young Russian star who has played with great consistency since he commenced playing competition. He was previously coached by GM Sergey Dolmatov. His current coach is GM Sergei Yuryevich Shipov (1), who described Dubov’s style as being akin to that of Tigran Vartanovich Petrosian. > Compare that to:
<spingo: Dubov is a superb, Tal-like player and I hope he gets a crack at the title, say in 2028 or so.> Ha! Which is it, Petrosian or Tal? From this game alone (I haven't seen his others yet), I'm going with Tal. |
|
| Nov-29-20 | | carpovius: Mate in 14? After 25.Bxd5 all moves are forced. Wow! |
|
| May-21-23 | | Kingsider: reminds me a bit of Korchnoi vs Vaganian, 1989 |
