Mar-18-21  SeanAzarin: Black was so focused on his own attack that he neglected to defend against White's.

Reminds me of the 19th-century battles between McDonnell and LaBourdonnais, or Anderssen and Zuckertort.

  Check It Out: Smashing game, and a pun 7 years in the making. Good stuff.

  An Englishman: Good Evening: Stunning game. At the end, White is down a Knight, Bishop, Rook *and* Queen, and yet his f6 and g7 pawns outweigh them all.
Mar-18-21  goodevans: Highly entertaining GOTD.

Try as I might I can't see how Black saves the game after accepting the N-sac. Perhaps he should just have retreated <22...Qd8> since if <23.Nxh6+> then <23...Bxh6 24.Bxh6 Qh4> regains the pawn.

Mar-18-21  Swedish Logician: This reminded me of another Swedish classic.

Mar-18-21  Ironmanth: Beautiful finish! Thanks, chessgames. Y'all stay safe out there.
Mar-18-21  Brenin: <goodevans>: After 22 ... gxf5 23 gxf5, retreating the N to b7 rather than c6 might have been better, allowing the R to defend the K-side along the 6th rank after a5 and Ra6 (as played in the game). From b7, the N could also challenge White's B if it moves to b3, by Nc5 (and if Bd5 then Bb7). I'm not claiming this as a refutation of White's N sacrifice, but it might have been better for Black than the line played.
Mar-18-21  goodevans: <Brenin> I did look at 23...Nb7 for one of the reasons you gave in particular, ...Nc5 against Bb3. I wasn't sure how significant that would be. Like you say, it seems better than 23...Nc6 but whether it's good enough to parry the attack is beyond my analytical ability.
Mar-18-21  spazzky: Engine says Black can survive with an equal game:

1) =0.00 (21 ply) 23...Nb7 24.Ke2 Qf6 25.Rh1 Nc5 26.Qg4+ Kh8 27.Rh3 a5 28.Rah1 Ra6 29.Rg3 Qg7 30.Qh4 Qf6 31.Qg4

Mar-18-21  goodevans: <spazzky> Which engine?

Most can get positions like these very wrong at around 21 ply and SF, with its aggressive pruning, is particularly liable to make mistakes in these sorts of positions. If you want proof of that just look at the nonsense it came up with towards the end of the game that <Swedish Logician> posted.

  beatgiant: <spazzky>,<goodevans> When in doubt, look at the position itself.

After <...Nb7 24.Ke2 Qf6 25.Rh1 Nc5 26.Qg4+ Kh8 27.Rh3 a5 28.Rah1 Ra6 29.Rg3 Qg7 30.Qh4 Qf6>

Now doesn't <31. Bg5> win (instead of the engine's repetition with 31. Qg4)?

Mar-18-21  goodevans: <beatgiant> Indeed it does, but if the engine got it wrong with white's 31st move how can we be sure it didn't make an earlier mistake with a suboptimal move for black?

Just goes to show again that the engines can't be trusted on fairly low ply in these complex positions.

Mar-18-21  Cibator: <SeanAzarin: Black was so focused on his own attack that he neglected to defend against White's.> Yes, a certain lack o' care there.
Mar-18-21  Cheapo by the Dozen: Great pun, since some of those advanced pawns could easily be construed as unremovable thorns.
