  beenthere240: White had a pretty scary attack for a while, but it lost steam. I have no idea where 30. Nf3 could have come from. Maybe he thought the g pawn could queen.

  ajile: Nice to see this variation crushed once again. Although eventually White players will get the message this attack doesn't work against strong prepared opposition.

  ajile: Here is a previous game in this line where White won.

G Welling vs J A Nilssen, 1997

Polgar's improvement is 11..Qe8 immediately challenging White's queen. White can't exchange pieces since without an attack he is simply down an exchange if Black consolidates.

  ajile: Hmm actually White had better here.
Plugged this into computer and after 11..Qe8 White has 12.Qxf5+ with a serious advantage - possibly winning.

Analysis by Rybka 3 32-bit :

1. (1.66): 2...e6 3.Qb5+ Kd8 4.Qxb7 Qc6 5.Qb3 Qb6 6.Qc2 Bg7 7.e5 dxe5 8.d5 Kc8 9.Be3 Qb4 10.dxe6 Qxc4 11.Qf5 Nc6 12.Qf7 Bf8 13.0-0-0 Kb7 14.Nd2 Qh4 15.Nd5 Bd6 16.g3 Qa4

2. (3.86): 2...Kd8 3.Ng5 Nd7 4.Nf7+ Kc8 5.Nxh8 Bg7 6.Nf7 Bxd4 7.Ne2 Bg7 8.Nf4 Kb8 9.Ne6 Bf6 10.Qxh7 Qc8 11.Nfd8 Nc5 12.Qh3

The queen check on b5 is a problem so Black must improve somewhere earlier in the line.

Nov-30-10  hedgeh0g: 12.Qh3?! is a curious move. I imagine he wanted to recapture with the pawn to open the e-file, but he never got enough time to make use of it. The weak light squares in Black's position are far more crucial and some well-placed queen checks would maintain a good position for White.

The simple and obvious Qxf5+ looks much stronger than the game continuation. Retreating the Queen to unnecessarily maintain a pin reminds me of the recent Topalov-Anand game (Bilbao?) where Topalov's refusal to make a simple recapture (on c5?) proved costly.

Nov-30-10  Riverbeast: Since when did Polgar start playing the Leningrad Dutch?

Maybe Nakamura is starting a trend?

  ajile: I underestimated this opening. Even if Black deviates earlier there are long term problems to overcome. White is saccing the exchange but Black has difficulties with development that compensate White. For example:

1.d4 f5 2.c4 Nf6 3.Nc3 g6 4.h4 <Bg7> and Black deviates from the above game but still has problems.

5.h5

Nxh5 6.e4! (This inbetween move makes White's attack better)

6..fxe4 7.Rxh5 gxh5 8.Qxh5+ Kf8 9.Qf5+ Kg8 and now Black can't castle and the Rh8 is entombed and difficult to develop.

So far all my short Rybka engine matches have been won by White in this line.

So maybe it's just safer for Black to decline the exchange sac with 5..d6? White doesn't get much after 6.hxg6 hxg6 7.Rxh8 Bxh8.

Unfortunately White has the unclear 6.h6!? pushing the Bg7 back to f8. This can't be bad for White. So probably Black needs to improve earlier to play a non sac variation.

Black could also deviate with 4..h6 intending 5.h5 g5. I believe this has been tried in a few games.

  ajile: <hedgeh0g: 12.Qh3?! is a curious move.>

Really just a bad move that allows Black to escape. Topa probably didn't see the queen check on b5. I guarantee that Polgar doesn't ever play this line again. It's just plain suicide.

Nov-30-10  hedgeh0g: My theory is that his preparation for this line excluded Polgar's ...Qe8? move. This move actually loses on the spot after Qxf5+, since, after a check on b5, the Black king can no longer protect the b-pawn since the queen is hanging. He might have had a similar position in mind when playing Qh3.

  jmboutiere: 25.Re6 better than 24.Rf4
26.Bb4 better than 26.g5
30.Nf3 is the decisive mistake, 30.Ng2 seems better
Dec-01-10  patzer2: If 6. e4, why can't Black just simply play 6...Nf6 and go on with development?

Black will likely have to give back the extra pawn to equalize, but it does seem to offset any advantage 6. e4 might offer over 6. Rxh5.

Dec-01-10  patzer2: Give Polgar credit for playing chess with some human risk involved, and not just following computer opening lines in this tournament.

Her 11...Qe8!? may be a mistake with perfect play, but over the board even the stronger 12. Qxf5+! line given by <ajile> and Rybka 4 still give a human opponent, especially in rapid play, a lot of problems to solve over the board.

I don't have a Rybka program, but in playing this line out with Frtiz Black seems to come pretty close to equalizing. However, the complications are great, and probably suitable to the taste of a GM like Judit Polgar who likes to get into difficult tactical contests where her opponent is forced to rely entirely on his own resources (i.e. completely out of his opening preparation and in uncomfortable and unfamiliar positions).

You are talking about the 1.d4 f5 2.c4 Nf6 3.Nc3 g6 4.h4 <Bg7> correct?

I guess it doesn't matter that much whether it's the 4..d6 line or 4..Bg7 line. Black can of course play the Knight back to f6 if White tries 6.e4.

After 1.d4 f5 2.c4 Nf6 3.Nc3 g6 4.h4 <Bg7> 5.h5 Nxh5 6.e4 Nf6 7.exf5 gxf5

Black's k-side pawn structure is busted up. Not really what you are looking for if you play the Leningrad Dutch.

Dec-01-10  patzer2: <ajile> What I had in mind was 1. d4 f5 2. c4 Nf6 3. Nc3 g6 4. h4 d6 5. h5 Nxh5 6. e4 Nf6 7. exf5 Bxf5, when Black's pawn structure (diagram below) is just fine.

White will likely castle Queenside and go for an attack, but Black is not without defensive resources and counter chances, especially if the all out attack on the Black King fails.

Gotcha. 4..d6 does seem to work since
5.h5 Nxh5 6.Rxh5 gxh5 7.e4 fxe4 is pretty much an admission by White that the game is a draw.

Analysis by Rybka 3 32-bit :

1. = (0.00): 8.Qxh5+ Kd7 9.Qh3+ Ke8 10.Qh5+ Kd7 11.Qh3+ Ke8 12.Qh5+ Kd7 13.Qh3+ Ke8 14.Qh5+ Kd7 15.Qh3+ Ke8 16.Qh5+ Kd7 17.Qh3+ Ke8 18.Qh5+ Kd7 19.Qh3+ Ke8 20.Qh5+ Kd7 21.Qh3+ Ke8 22.Qh5+ Kd7 23.Qh3+

2. (-0.69): 8.Be2 Bg4 9.Bxg4 hxg4 10.Qxg4 Qd7 11.Qxe4 Nc6 12.Nge2 Bg7 13.Be3 Rf8 14.Qxh7 Qg4 15.0-0-0 Rh8 16.Qc2 0-0-0 17.d5 Nb4

If White doesn't take the perp he will be noticeably worse.

  ajile: So in both lines Black comes out OK.

6.e4
6.Rxh5

  ajile: Couple of games:

D Reinderman vs E Van Beers, 2001

Black should have played as in patzer2's line. 6..Nf6 instead of 6..fxe4.

And 1. d4 f5 2.c4 Nf6 3.Nc3 g6 4.h4 d6 5.h5 Nxh5 6.Rxh5 gxh5 7. e4 leads to this position with Black having either 7..Qd7 or 7..fxe4 as decent options.

7..Be6 as in the game does not score well here and is dubious IMO.
