Jun-13-17  catlover: It's interesting that on moves 35 and 36 Stockfish rated the positions more or less even. That changed with Kanep's 36...Nxd4 which permitted Nguyen to simplify to a rook and pawn ending with four pawns versus Kanep's two.

  piltdown man: Outstanding pun!
Jun-13-17  ColeTrane: Nguyen is common like Rodriguez...but how does one pronounce the first name....? Flied Lice anyone....?
Jun-13-17  nikromos: Pin and Nguyen would have been my choice, given how the game went.
Jun-13-17  JohnBoy: <bcokugras> 21...de3 22.Qh5+ Kg8 23.Qh7+ Kf8 24.Qh8+ Ke7 25.Qg7+ Ke8 26.Qf7#

On a phone w small screen, but pretty sure this works.

Jun-13-17  JohnBoy: <catlover> - It sure looked to me on initial view that 36...Rd4 was the way for black to proceed.
Jun-13-17  morfishine: Yeah, lets just bastardize another player's name for a cheap chuckle

Real classy stuff around here

*****

Jun-13-17  catlover: <JohnBoy> I think you're right. 36...Rxd4 would have kept the game fairly even.
Jun-13-17  LivBlockade: This line was repeated in Le Thao Nguyen Pham vs A Zatonskih, 2012 when Black tried 15...Qb5, also without success.
Jun-14-17  kevin86: White's kingside pawn majority carries the day.

Stockfish 16 says:

13. Bxh7+

(13. Bxh7+ (1.Bxh7+ Kxh7 2.Qh5+ Kg8 3.Ne4 g6 4.Nxc5 gxh5 5.Nxd7 Rfc8 6.Nf6+ Kf8 7.Nxh5 b5 8.Ke2 b4 9.Rhc1 Rab8 10.c4 d4 11.b3 a5 12.Rd1 Rd8 13.Nf4 a4 14.Nd3 dxe3 ) +2.44/45 206)

score for White +2.44 depth 45.

Apr-20-24  Viennablue: Hard to say why black didn‘t play 34…Nxd4. SF evaluates this a mere +0.48 for White.
Apr-20-24  MisterFreeeze53: LOL. Another 1 star masquerading as a 4 star.
BxH7/ Qh5 every time. There's way harder moves later.

  FSR: Too many stars, as <MisterFreeze53> said. This is a famous trap in the London System. 13.Bxh7+! Kxh7 14.Qh5+ Kg8 15.Ne4! exploits the pin along the fifth rank. Note that because Black's bishop is hanging, 15...g6 doesn't solve Black's problems, since White can play simply 16.Nxc5 gxh5 17.Nxd7 Rfd8 18.Nf6+ Kh8 19.Nxh5.

  perfidious: Famous it may be, but I had never seen this version of the motif; the pieces are usually eyeing the enemy king in much more baleful fashion, and there are more of them.
Apr-20-24  Cecco: <Viennablue: Hard to say why black didn't play 34. Nxd4. SF evaluates this a mere +0.48 for White.> Yes, according to the engine white wastes a huge advantage, but black doesn't take advantage of it. White's best plan was 21. f4, to bring the Rh1 to f1 (possibly castling) and then to f3. And in the game, after 21. h4 Qd5, white doesn't prevent the exchange of queens with 22. e4, which forces black to suffer a large loss of material to defend himself.

  FSR: Note that 10...Bxd7?, despite being the most natural move in the world, is a blunder allowing White to get a big advantage with the Greek gift sacrifice seen in the game. After 10...Qxd7!!, Black is fine. See Opening Explorer. White can still play the same bishop sac, but with Black's QB safely at home on c8, it only draws: 11.Bxd6 Qxd6 12.dxc5 Qxc5 13.Bxh7+ Kxh7 14.Qh5+ Kg8 15.Ne4 g6! 16.Qg5 Qe7 17.Nf6+ Kg7 18.Nh5+ and now either 18...Kg8! or 18...Kh7! and White has nothing better than perpetual check.

  FSR: As <LivBlockade> noted, two years later Le Thao Nguyen Pham repeated Truong Song Nguyen's success in this game, playing the same sac and winning in Le Thao Nguyen Pham vs A Zatonskih, 2012. But six years after that Van Thanh Nguyen missed the sac and only drew in V T Nguyen vs I Farago, 2018. Of course <Nguyen> in Vietnam is like <Smith> in England.

Apr-20-24  thegoodanarchist: The line of play in the game was the first line to pop into my head. Wednesday or even Tuesday level stuff IMHO.

  al wazir: 16...Qd3. Now what?
Apr-21-24  FM David H. Levin: <al wazir: 16...Qd3. Now what?>

On 16...Qd3, 17. e4 seems the only effective way to continue the attack. Then a plausible continuation might be 17...Rfd8 18. Qxf7+ Kh8 19. Qh5+ Kg8 20. Qh7+ Kf8 21. Qh8+ Ke7 22. Qxg7+ Kd6 23. Rd1 (To chase Black's queen to where it no longer controls the e4-square.) 23...Qc4 24. b3 Qb5 25. Nf7+ Kc7 26. Qg3+ Kb6 27. Nxd8 Rxd8 28. Qe3+ Kc7 29. h4, and White's material advantage should be enough to win.
