The Bryntse Gambit

[Dann Corbit]

Thanks for the game. I imagine there might be positions worth investigating that I have not analyzed yet.

[Dann Corbit]

I see that this game does not have the queen sac/weird imbalance. I am looking at just those right now

[jp]

Yes, because it's the Scandinavian start where 4... Bg4 is a blunder, so a good Black player will play 4...e6 and there's no opportunity for White to sacrifice.

I was just (not thoroughly) looking for a game where it even got close to the line appearing OTB.

It looks like Smagin erred with 24...b5? instead of ...Nxg4, but White needed to play 26.Bd3 instead of Qxa6 to punish him.

There is a very similar line.

1. f4 d5 2. Nf3 g6 3. e4 dxe4 4. Ng5 Nf6 5. Bc4 Bg4 6. Bxf7+ Kd7 7. Qxg4+ Nxg4
8. Be6+ Kc6 9. Bxg4 *

Yes, this looks like it might have some chance of appearing OTB.
SF, depth=27, evaluates this as (-1.99) with PV 9...Bg7 10. Nc3 h6, etc.

[d]rn1q1b1r/ppp1p2p/2k3p1/6N1/4pPB1/8/PPPP2PP/RNB1K2R b KQ - 0 9

Here's a game in this 1.f4 line that White wins with the sacrifice.

[pgn][Event "corr CAPA Bartis Memorial B"] [Date "1995.??.??"] [White "Calua, Alcires Miguel"] [Black "Laplaza, Jorge"] [Result "1-0"] 1.f4 d5 2.Nf3 g6 3.e4 dxe4 4.Ng5 Nf6 5.Bc4 Bg4 6.Qxg4 Nxg4 7.Bxf7+ Kd7 8.Be6+ Kc6 9.Bxg4 e5 10.Nf7 Qf6 11.Nxe5+ Kb6 12.Nc3 c6 13.g3 h5 14.Nxe4 Qg7 15.Bh3 Na6 16.d3 Nb4 17.Be3+ Ka6 18.Kd2 Be7 19.c3 Nd5 20.Bd4 c5 21.Bxc5 Nf6 22.Bd4 Rhd8 23.Ng5 Rxd4 24.cxd4 Ng4 25.Ne6 Bb4+ 26.Ke2 Qe7 27.d5 Nxe5 28.fxe5 Rd8 29.a3 Ba5 30.d6 Qe8 31.Rac1 Bb6 32.Rc5 Bxc5 33.Nc7+ Kb6 34.Nxe8 Rxe8 35.d4 Bxd6 36.Rf1 1-0 [/pgn]


SF at low depth dislikes 9...e5 and thinks 10...Qf6? is bad (a draw).
After 12. Nc3, SF's line at low depth is
(0.00) 12... Qd8 13. d3 Nc6 14. Be3+ Ka6 15. O-O Nxe5 16. fxe5 Bh6 17. Bxh6 Qh4 18. Bg7 Rhg8 19. Rae1 Rxg7 20. Rxe4 Qg5 21. Ra4+ Kb6 22. Rf6+ c6 23. Nd5+ Kb5 24. Nc3+ ...

It looks like SF thinks 17...Ka6? is the tipping point.
+0.62 17...Kc7
+2.03 17...Ka6
depth=28.

After 27. Nxe5?, Black is totally busted.

I imagine there might be positions worth investigating that I have not analyzed yet.

I think this game might have some.

[Dann Corbit]

Thanks, I'll take a look

Thanks, Mike. What does the constant "+60" before each PV mean?
