  rodchuck: Tragically, Ivan Bukavshin died in 2016 at the age of 20. I can't add anything to the eulogy on http://en.chessbase.com/post/ivan-b...
Jun-26-17  Ariogermano: Very simple ! Yesterday it was hard
Jun-26-17  mqhelisi: Inakiev to be honest didn't notice him but has a few sculps including Nepomniachi at some point
Jun-26-17  Iwer Sonsch: 41.Nf6+ Qxf6 42.exf6 wins the Queen, I guess.

41...Kf8 42.Rh8+ Bxh8 Qg8# is mate.

Jun-26-17  zb2cr: Simple. 41. Nf6+. Black has the choice of the immediate, obvious loss by 41. .. Qxf6; 42. exf6 or the slightly delayed loss with 41. ... Kf8; 42. Rh8+, Bxh8; 43. Qg8#.
Jun-26-17  eblunt: Not as spectacular but 41: Bh4 has mate or Black losing the Queen coming very quickly.
Jun-26-17  beenthere240: I agree that 18. Be4! is a spectacular move. It pulls the teeth of any black counterplay and establishes a long and finally successful attack.

  kevin86: White mates in three!
Jun-26-17  RandomVisitor: If instead 18...fxe4 it is mate in 13. Note how white brings an extra piece in play by Kh2-Rh1-Kg1.

  Once: Well, yes, but ...

42. Rh8+ Bxh8 43. Qg8# is the obvious way to win, but which of us with secret Blofeld tendencies couldn't resist torturing black with 43. Nh7+ instead?

Black and white are playing a warped game of draughts (chequers) where black is hogging all the dark squares and white is monopolising the light.

Okay, okay, okay, so it isn't mate in 1. But just look at that trapped king! White will have great fun teasing the colour-blind black pieces.

Jun-26-17  stst: N to work, Black Q looker-on:
41.Nf6+ if (A)QxN, then 42.Rh8#
if (B)Kf8, same 42.Rh8+ BxR, 43.Qg8#
Jun-26-17  stst: < torturing black with 43. Nh7+ instead?>

Then QxN, QxQ, Nf7 to get some shield...game prolonged, but, of course, Black is struggling painfully...

Jun-26-17  Weeping Warrior: 41.Bh4 Qf7 42.Nf6+ Kf8 43.Qg3 Qc7 44.Nh5 Nc6 45.Qa3+ Works Also.
Jun-26-17  RandomVisitor: Ivan Bukavshin dies at the age of 20
by Sagar Shah
1/13/2016 – He was one of the brightest talents in the world of chess, with an impressive rating of 2658. On 12th of January 2016, at the age of just twenty years and eight months, Ivan Bukavshin died from a stroke, leaving the entire chess world in a state of shock. The 2015 Russian Cup winner is no longer with us. What a player he was, what a beautiful chess career it would have been.

Jun-26-17  patzer2: After a few seconds of calculation, I found the mate with 41. Nf6+ Kf8 42. Rh8+! Bxh8 43. Qg8# for today's Monday puzzle solution.

White might have missed an opportunity for a slightly quicker win earlier on his 16th move. Instead of the preparatory 16. e5 gxh5 17. Ng5! , White appears to secure an immediate winning position with 16. Ng5! Qe7 17. d5 (+2.31 @ 31 depth, Stockfish 8.)

However, after 16. e5 gxh5 17. Ng5! (+1.07 @ 28 depth, Stockfish 8) I must admit it's very difficult to find a saving resource for Black. Indeed, in this game, Black quickly misses his last chance to fight for the draw with 17...Qe8 18. Be2 (+1.15 @ 29 depth, Stockfish 8)

Having missed 17...Qe8 , Black finds himself in a clearly lost position after 17...Qd5? which allows the strong and forcing 18. Be4! Qd7 19. Bxb7 Nxb7 20. Qxh5 (+3.95 @ 36 depth, Stockfish 8.)

Black's game starts to go bad with the weakening 15...f5?, allowing either 16. Ng5! or 16. e5 gxh5 17. Ng5! . Instead, 15...Rc8 = to (+0.41 @ 31 depth, Stockfish 8) or 15...Qe7 (+0.55 @ 31 depth) or 15...Nc6 (+0.55 @ 31 depth) are better alternatives for Black.

Early in the opening, instead of 8...Nc6, I prefer the popular reply 8...Qa5 = (0.00 @ 36 depth, Stockfish 8) as in the hard fought draw Akobian vs J Xiong, 2017.

Jun-26-17  RandomVisitor: However, digging deeper, an article translated from Russian questions this:

Ivan Bukavshin died of poisoning, but nobody cares

The Tolyatti newspaper Freedom Square published a story about Ivan Bukavshin, which reports that on January 12 of this year the grandmaster suddenly died not because of a stroke, as information appeared earlier, but from acute poisoning with No-Shpa. This is the result of forensic research. A monstrous concentration of the drug was found in the chess player's body: 17.21 mg / kg in the blood, 36.18 mg / kg in the stomach, 53.23 mg / kg in the liver, 48.67 mg / kg in the kidney. According to the conclusion of the examination, these concentrations exceed the minimum deadly three to four times. The death of the athlete came quickly, no traces of alcohol or drugs in his blood were found. All this happened on the last night of the collections of the Grandmaster School of the Russian Chess Federation, in which Bukavshin took part.

We contacted Ivan's mother, Elena Bukavshina, who confirmed that everything written was true and told some more details.

After the forty days from the moment of Ivan's death, the phones of his parents were silent. Neither those responsible for the charges, nor anyone at all from the RCF are not interested in what happened, although it became clear from February that the death of the grandmaster did not come from a stroke.

Jun-26-17  King Harvest: This (very promising) kid was apparently murdered (while living at a training camp) and nobody wants to look into who or why? It's incredible.
Jun-26-17  eblunt: <Weeping Warrior> Yes thanks for the detail on that line, 41.Bh4 wins pretty quickly.
Jun-26-17  morfishine: Pretty straight-forward despite all the superflous postings

  rodchuck: It would seem that poisoning of critical opponents of the Russian regime (Alexander Litvinenko for example) is not exactly unknown, but why murder a promising young chess grandmaster?
Jun-27-17  morfishine: Rather wonderful series of moves by White exploiting the holes in Black's position. Very entertaining

However, instead of 33.Rc3 the improvement <33.Rxd8> would've wrecked Black's position beyond repair

but that's neither here nor there

*****

Jan-15-20  seneca16: 24 Nxh7 looks promising. If Rxg3 then Nxf8 is strong. Where does the queen go, since Rc8 is looming? Kxf8 runs into Qxh8 Rg8 Qf6+ which looks like winning.
Jan-17-20  jith1207: I liked following alienate moves in the game as well.

40. Rh8+ Bxh8 41. Nh7+ Qxh7+ 42. Qxh7

And

37. Rh7 Qg6 38.Qd7

Jan-17-20  jith1207: *alternate.
