The Petroff Defence is an exceptionally reliable and almost indestruct- ible opening, and a hard nut to crack, even for the strongest and most meticulously. The Petroff Defence is considered as one of Black's most reliable methods of meeting the king's pawn ChessCaissa wrote: PDF ( mb). The Petroff is a quiet success story in chess - an old and often forgetten after 1. e4 e6 2. d4 d5 3. exd5 exd5 (the Exchange Variation of the French Defence).
And in the Petroff: 1. Bd3 Be7 7. O-O Nc6 8. Nc3 dxc4 Bxc4 O-O Nc3 Nd6 White's ideas will still be the same: develop quickly, use the extra space to dodge about, avoid exchanges to keep Black cramped , play Ne5, look for a chance to start a King's-side attack using the light-squared bishop, maybe throw in Rf1-e1-e3-h3. So, let's have a look at some variations. The Classical Variation, 3.
Nxe5 Black must now play Why not White answers 4. Now Qxe4 d6 6. So, from the first diagram in the column: Nf3, but there are two alternatives: 4.
Nxf7, the Cochrane Gambit, and 4. I have never seen this last move played, and I don't think it is dangerous, but it does deny Black the natural Bg4 pin. BCO recommends 4. Nc4 Nxe4 5. Ne3 Qf6 and Be6 with an early O-O-O in mind. So that leaves us with the Cochrane Gambit to examine before we go down the main line. An alternative on move 4 for White: 4. Nxf7, The Cochrane Gambit Looks crazy? Looks promising? Your chess personality may make you feel confident as White or Black in this position, but either way, you must know about it.
Kxf7 5. Qxe4] [ Bd3 g6 8. Nc3 Now BCO recommends the odd-looking: Qe8 Other tries seem inadequate, e.
Bg7 7. Re8 O-O Nc6 Nb5 Re7 Qf3 c6 Main line with 4. Nf3 Black should take the chance to recover the pawn with Qe2, the Lasker Variation, leading to an early endgame, or 5.
Qe2, Lasker Variation This pin is not dangerous here with the White Knight on f3, just awkward for the moment. Qe7 6. Bg5 Nbd7 8. This variation is why the Petroff is no good when you have to win as Black against a player who knows this line.
Bd3 Like White, Black should plan to get the K off the open e-file as soon as possible, and Black has a choice of two squares for the Bf8: a Bd6, a move of Frank Marshall - which looks good but is perhaps trying a bit too hard - or the safe b Be7, sealing the e-file.
Bd6 Marshall Gambit Let us follow the play after the natural moves: 7. O-O O-O 8. This is Marshall's idea.
One natural move too many. Kxh2 Nxf2 Qc2 Nxd3 Qxd3 Bxf3 winning, because if Qxf3, then Nf3 Nxe4 5. Is there one? We also have articles for all of White's first opening moves, even though many of them are classified as irregular openings and barely treated in the standard references, since the irregular openings have little in common except that they are uncommon.
Variations should be described in the parent opening article.
I think B-K could definitely support a separate article, but I recommend expanding the section here first. When it gets out of proportion to the discussion of the rest of the Petrov, split out the more detailed part of the section to a new article. Hope this helps. Bc4 Nxe4 4. Nxe5, but this doesn't seem to be mentioned on the page. It seems to be less bad for White than 3.
Nxe5 Nxe4 is for Black, but it's very unclear and I'd like to see some analysis. With so many chess opening articles, it's often confusing to remember exactly what format the title of a particular one is in. Nxe4 Qe7[ edit ] what about this line? I'm actually playing a game in which that happened.
I played 4.
Now I can't decide between Nc4, Nd3 and Nf3, and I'm trying to figure out why this line isn't in any books or the net. Hi, 3. Nxe4 is not possible, the Knight just went 2. I'm guessing you mean 3.
Nxe5 followed by Qe7. The line is not theory at least I can't find it in theory anywhere and it's rarely played, but follow this. Nxe5 Qe7 4. Nc6 5.
Be2 Qxc6 7. O-O White with advantage for White 5. Nf3 Qxe4 Nxe4 problem with this Knight for Black is the Black bishop is blocked in by the Queen and so Kingside castling is slow.
