Jan-10-04  Benjamin Lau: Bronstein vs E Rojan, 1956 is an interesting two knights game.
Feb-14-06  Bobak Zahmat: Interesting. When the above position arires on the board White wins 42,7% and Black 40,1%. So there is a tiny chance to draw the game after reaching the mentioned position.

  refutor: <bobak> that's mostly because half the games were from pre-1900. and the other half are played in the brazilian girls U10 championship :)
Feb-14-06  Bobak Zahmat: <refutor> Still, this position should be analysed well, before we judge too fast about the it.
Feb-14-06  Bobak Zahmat: Even the great Adolf Anderssen had some trouble with playing this Defense with White. Out of six games he has lost two.
Feb-14-06  micartouse: <Bobak> If you haven't already, take a look at 5 ... Nd4!? (right into the center) instead of the above 5 ... Na5!? There are many fun and respectable lines springing from the "Fritz Variation."

A common snare: 6. d6?! Qxd6 7. Nxf7 (7. Bxf7+ Ke7 intending ... h6) Qc6 8. Nxh8? (8. 0-0 is still much better for Black) Qxg2 9. Rf1 Qe4+ 10. Be2 Nf3#.

There are many other wild variations as well after 6. c3 b5. Very good practical opening I think and it doesn't require too much prep.

Feb-14-06  Bobak Zahmat: <micartouse> I like 5. ... Na5 more than the move Nd4. Because after 6.c3 Nf5 White has the better game with d4!?
Feb-14-06  Bobak Zahmat: <micartouse> The move 6.d6 isn't that strong. White will lose the initiative and probably the game with your continuation.
Feb-14-06  micartouse: <Bobak> True, Na5 is a great move too, I was just throwing it out there for anyone into "somewhat sound" gambits for Black.

I agree that in the Fritz, 6. c3 is the best option for White, but 6 ... b5! not ... Nf5? Then for instance, 7. cxd4 bxc4 8. dxe5 Qxd5!

White rarely knows 7. Bf1! is best, and even then Black has a little (but not enough) compensation for the pawn.

Anyone who plays the Fritz at class level will not be disappointed if they like risky sharp chess.

Feb-14-06  Bobak Zahmat: <micartouse> It is quite right that not everyone could find 7.Bf1! But if one takes enough to think it through this move should be seen, because it is actually forced.
Feb-14-06  micartouse: <But if one takes enough to think it through this move should be seen, because it is actually forced.> Not to be overly picky, but there are other moves such as 7. Bd3 that retain the pawn for White and seem more correct, and such moves are more commonly seen in practical play. So 7. Bf1 is not forced by any means.

Even after 7. Bf1, Black gets some tricky attacking options. I will let the point go though; I just think gambit lovers have a sound gambit in the Fritz and an easy one to play. Anyone under 2100, and probably a little over will find it a safe bet. :)

  refutor: i agree trumbull...this is one of the main reasons why i don't play the "mainline" of the two knights as Black and prefer 6. ...Bd7, which is more passive but playable
Jul-16-08  jon01: My opponent went to a trap that loses queen in the opening.

Feb-20-09  FiveofSwords: <micartouse> The fritz variation is perfectly playable for either side, for anyone with rating less than about 3500.
Feb-20-09  drkodos: trumbull0042: What are the main strategies for Black, who is down two pawns, in the following line: 1. e4 e5 2. Nf3 Nc6
3. Bc4 Nf6

11. d3 Be7 ?

I take black side of this ANYDAY.

Wow, here is some "comp"

12. Ne4 Rb6
13. Qa4 f5
14. Ng6 0-0
15. Nd2 Nc5

Stick that on your silicon chipset and see if it doesn't show Black is almost equal.

Now many possibilities as Black has initaive, better piece develop and a King to attack. It is winning? No it is equal with some Chess to play!

For instance,

16. Qa5 Bb7 ?!
17. Nc4? Nxd3+ !

This 'tabiya' position of the Two Knights after 10. ...Be7 is one of the most important in chess to play because it really is fantastic demonstration of positional compensation for sacrificed material when no regaining material is to be had immediately.

Learn to play this as Black and your chess will get better in many, MANY positions.

Feb-20-09  chessman95: I've never tried this before as black, but I might play it in a few Two Knights games that I play. Looks like a fairly solid option.
Oct-03-10  LDJ: Does this opening with 5...Na5 have an own name (other than Two Knights with 4.Ng5 d5 5.exd5 Na5)? I know 5...b5 is the Ulvestad variation and 5...Nd4 is the Fritz variation, but what is 5...Na5 called?

  tpstar: 5 ... Na5 is the Polerio Defense named after Giulio Cesare Polerio as an alternative to the Fried Liver Attack (5 ... Nxd5?! 6. Nxf7!?) where Black continually gets killed (see Polerio vs Domenico, 1610 ). White's response 6. Bb5+ has the catchy name Bishop Check Line = Opening Explorer

  Eric Schiller: <tpstar> After 5...Nxd5?, the Lolli Attack with 6.d4! is much stronger. Practically a guaranteed win. See the Opening Explorer.
Oct-06-10  LDJ: Thanks <tpstar>. I knew about the Fried liver attack. Personally I prefer 6.d4 in that line, but I think it depends on your style whether you play 6.Nxf7 or 6.d4.
Oct-07-10  morphy2010: Bobby Fischer perferred 6.d4 due to whites overwelming pressure.
Apr-06-11  LDJ: An interesting game I played yesterday at my club, ending in a nice sacrifice which should have led to perpetual check but fortunately my opponent missed a nice mate :)

22...Bxh3! 23.gxh3 Qh1+ 24.Ke2??
<24.Kf2 Qh2+ 25.Kf1 leads to perpetual; 24.Kf2 Qh2+ 25.Kf3?? runs into 25...Qxh3+ 26.Kf2 Ng4+ and here white can avoid being mated by giving up his queen, but that's equal to resigning, I had seen the mate already when I sacrificed!; 24.Kf2 Qh2+ 25.Ke3? Nd5+ is mate in 10 according to Fritz, but of course I didn't see that in the game, when I sacrificed the Bishop I just thought I would have some good attacking chances after 25.Ke3>
