May-10-22		fredthebear: Najdorf plays the best defense 5...d5, grabs control of the center and carves up the White knights on the edge. Black to move [Opening Explorer] 1) -0.46 (29 ply) 5...d5 6.Ng3 Nc6 7.d3 Be7 8.Nf3 Rf8 9.O-O Kg8 10.h3 Be6 11.Bd2 Qd7 12.b4 Bd6 13.Bc3 Qf7 14.b5 Nd4 15.Nxd4 exd4 16.Bxd4 a6 17.a4 Bd7 18.Qh5 axb5 19.axb5 Bxb5 20.Rxa8 Rxa8 21.Qf5 2) -0.04 (29 ply) 5...Nc6 6.Qf3+ Ke8 7.Ne2 d5 8.N4c3 d4 9.Ne4 Qd7 10.d3 Qg4 11.Qxg4 Bxg4 12.Bd2 Kd7 13.a3 Bf5 14.N4g3 Bg6 15.O-O Bd6 16.f4 Rhf8 17.Rae1 h6 18.f5 Bh7 19.Nh5 Bxf5 20.Nxg7 Bg6 21.Bxh6 3) +0.12 (29 ply) 5...Kg8 6.d4 exd4 7.Qxd4 d5 8.Nc3 Be6 9.Nf3 Nc6 10.Qd1 h6 11.Be3 Na5 12.Bf4 c5 13.O-O d4 14.Ne4 Bd5 15.Re1 Nc6 16.b3 Qd7 17.c4 Bf7 18.h3 Re8 19.Ng3 Rxe1+ 20.Qxe1 Bg6 21.Ne5 Nxe5 22.Qxe5 4) +0.39 (29 ply) 5...h6 Perhaps the reader has seen this miniature: Vienna Game: 1.e4 e5 2.Nc3 Nf6 3.Bc4 Nxe4 4.Bxf7+ KxBf7 5.NxNe4 d5 6.Qf3+ Kg8 7.Ng5 QxNg5 8.Qxd5+ Bd6 9.QxBd6# 1-0. See diagram of final position: click for larger view It's in the books, but not in this database. Again, 5...d5 is the best defense. 7...Qd7 works for Black. Chess author Byron Jacobs defended with 7...Qd7 this way: Lux vs B A Jacobs, 1989 So <3...Nxe4> is the Blanel Gambit. It invites the White knight to recapture the invading knight to set-up the center pawn fork trick 4.NxNe4 d5 and Black gains back the piece. In the game above, White played 4.Bxf7+ regaining the pawn before 5.NxNe4. White's immediate 4.NxN recapture is no advantage IF Black proceeds accurately. Instead of allowing the center pawn fork trick, White <often brings out the queen> to threaten checkmate ala Scholar's Mate. Then Black will retreat his en prise knight to good effect 4...Nd6, preventing checkmate and threatening the Bc4. Here's a speeding silent chess movie (arising from a 2.Nc3 Vienna Game) in the main line 4.Qh5 threatening checkmate on f7: https://www.bing.com/videos/search?... Here Mato explains the 4.Qh5 main line: https://www.bing.com/videos/search?... Kingscrusher provides us with another 4.Qh5 main line that arises from Alekhine's Defense: https://www.bing.com/videos/search?... Yes, he said 4.Qh5 "Frankenstein-Dracula" variation. Have we seen this variation yet? Here's more proof that chess has a universal language! https://www.bing.com/videos/search?... Look at the danger in this game: Guimard vs Najdorf, 1942 This entertaining double king pawn opening can take off in various directions. Like most gambits, it can be confusing and dangerous if one forgets the precise theory. Here's another video by Mato where both colors vary with their knights early in the game, taking a different direction (a likely transposition from a Blanel Gambit): https://www.bing.com/videos/search?...

May-10-22		fredthebear: Really, a well-prepared Black defender need not be afraid if s/he watches this video daily (Two Knights Defense material, and yes there's more to it, but oh what violent fun!): https://www.bing.com/videos/search?... Black will need to look up something against the Vienna Gambit <3.f4>, or this could happen: Najdorf vs NN, 1942 The Würzburger Trap could arise: 1.e4 e5 2.Nc3 Nf6 <3.f4> d5 4.fxe5 Nxe4 5.d3 Qh4+ 6.g3 Nxg3 7.Nf3 Qh5 8.Nxd5 etc. Here's one example: A Bartsch vs Weicht, 1988 Confused? Perhaps writing down the lines would help, then identify the losing move in each branch. Home preparation makes a difference.

May-13-22		fredthebear: Here's the Blanel Gambit miniature with 5...Nc6. Yes, Black could have also played 6...Ke8 instead of 6...Kg8. Kutjanin vs Jakobjuk, 1940 Thus, Black has more than one way to avoid this zap with a good game, so White really should play the main line instead of shooting for a quick knockout. Falling in love with an inferior line only works against inferior players; even they should eventually wise-up.

May-20-22		fredthebear: The links below are lesser fourth tries for White (non-captures) in the Blanel Gambit after 3...Nxe4. 4.Qe2 and 4.f4 have only one example thus far in the database, which usually indicates the move is unsound or it would have been played more often; the mainline 4.Qh5 is better but the Black defender should be expecting it. The rare link games are quite active and slip-ups are bound to happen. Is 4.Qe2 being aggressive? It develops another piece with a second threat, so it's not so terrible. The game resulted in an early queens exchange on the open e-file and eventually a rook and pawn endgame: Englisch vs M Judd, 1895 White plays 4.f4 in Bronstein's Gambit. Black has the theoretical advantage, but White wins this off-beat slasher film after the Black king changes course: C F van Tongerloo vs T de Veij, 1979 My brief notes regarding David Bronstein's application will be posted on that game page.
