Openings for Tactical Players: the Two Knights Defense.

Submitted by GM Gserper on Sun, 10/04/2009 at 9:11am.

Last week when we discussed the Urusov Gambit, we learned that the safest option for Black was to transpose the game to a very old and reliable line of the Two Knights Defense.  What an attacking player should do in this case? Well, the position after 1.e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. d4 exd4 has been extensively analysed for centuries and the most dangerous White's tries have been successfully neutralized.  It is enough to say that the main line was analyzed up to a pawn endgame!  Yet, there is always a way to stir a game into uncharted (or at least unknown for your opponent) territory. The first interesting moment arises after the customary 5.0-0 Nxe4 moves. White has what appears to be a totally crazy move: 6.Nc3!!?

 

In many cases if your opponent isn't prepared for this unexpected move, White gets a tremendous attack as the next beautiful game shows.
In the next game a strong IM got checkmated in just 12 moves!!
Of course we all know that if something looks too good to be true, usually it is! If White gets such a tremendous attack right out of the opening, why not everyone and his brother plays this tremendous line?  Well, because this line is just bad for White. The refutation is quite simple. If Black doesn't get greedy and instead of grabbing the material just finishes his development by 6...Nxc3 7.bxc3 d5 he simply keeps his extra pawn. That's why I gave 6.Nc3 two exclaims (for the beauty and surprise value) and a question mark for the real value of the move. So, the variation is unplayable, right?  Not necessarily. If you notice, the previous game was played in a blitz tournament and that's why a strong IM fell victim of this tricky line. I hope you got the idea. When your opponent has no time to calmly evaluate the position (which frequently happens in blitz), this variation can be a dangerous weapon, otherwise it cannot be recommended. (read more about good and bad traps in my article "The Good, The Bad and The Ugly").
But the question still stays. You are playing a regular tournament game and you don't want to bluff.  How should you play in this case?  Here is another surprising line that is not played frequently (at least for the last 50 years or so) and isn't refuted. It started with a classical brilliance that was featured in all  opening manuals and which was won by Black!
But White's play can be improved, as the next game shows.
As you can see, even in such an old opening as the two Knights Defense, you can always find a less explored path.
Next time we'll look at the same opening from the Black's point of view!

In the first example: Sokolov vs. Ruzhnikov correspondence game 1966

After the move Qg5, black cannot play b8=Q+, because of the move Re1+ (discovered), black will lose the Queen and fall behind in material. This idea might be easy to others but I tend to miss this stuff if I don't think it over.

I made a puzzle with similar ideas to this.

In the first game, what if 18. ...Kb6? It would seem as though black is fine.

@shaviani, if the black promotes, white plays discovered check by Re7-e1(blocking also the black's check by the promoted pawn... the best reply for black though is Rf8-f6 (but only prolonging its sudden loss.)

If black promotes his pawn on his 19th move, he wouldn't have the H pawn attacking the queen. And then White would do Re1 dis. ch and then capture the new queen on the next move.

I don't see why black doesn't promote the pawn in the first example with solution, because even after Re1+ with the queen, black takes the queen with the pawn and white has only the exchange of Rxb1 then black is up a rook and a pawn.

because if black promoted then white would move the rook down and check by reveal the king. In which case black would then lose the recently aquired king.

"Why didn't black promote the pawn to a queen in the first one?  It's checkmate after white throws the rook and queen in the way."

White would then bring the rook back, putting black in check, after which white would take the newly promoted queen.

Thanks percivalfox, I forgot that after Qg5, Re1+ comes with a check! What a beautiful move!
