Don't bother. I know LDZ doesn't dislike me and I am happy that he's back to chess. As for me, I've had my fun, I've made my point and am done for the time being. Moreover I will be glad if LDZ proves me wrong - with concrete moves. For that's what I have asked him.  Wink

All of a sudden, you guys start saying the Zilbermints Gambit offers practical chances. Wasn't it a couple of days ago that you were claiming refutation this, refutation that? LOL!  Grin  And now, after I post all that analyses, you say, "Oops! We were wrong!"


Lev, this line does offer some practical chances.  Very few gambit lines don't.  I don't know who was here saying that this doesn't offer practical chances.  I wasn't and I didn't see anyone else saying that either.

The debate is about the soundness of the gambit, not whether or not it offers practical chances.  The main idea is really a trap: 9...Nxf3? gives White a good game.  If you want to stake your chances as White on an unsound gambit, be my guest.

If Black plays 9...c5, I don't think that White's chances are anywhere near enough to make up for the lost pawn.  And 9...Nc6 also looks promising for Black.

I told you before, I analysed all the variations. But you did not want to listen, throwing out different moves.


People came here and as a favor to you analyzed your gambit.  The conclusion that stands so far is that it's unsound.  You didn't analyze all the moves.

So yeah, an interesting re-evaluation of the Zilbermints Gambit. Now it offers practical chances, is a nasty trap, etc. I don't think it is unsound, as there is plenty of room for Black to go wrong. And you guys finally admitted as much. Grin


"Room for Black to go wrong" bears on practical chances, not on soundness.  Do you understand the distinction?  The ball is in your court on soundness.  To demonstrate soundness you'll have to find sufficient comp for White after 9...c5 and 9...Nc6.

@SWJediknight:  You think it's only =+ after 9...c5 10.Bxf6 Bxf6 11.Nxd4 Bxd4?  That surprises me.  I probably agree, however, that 11.Nxd4 looks better than Lev's 11.Ne4.  11...Bxd4 12.Qh5 g6 13.Qh6 Bd7 and Black at least is inconvenienced by his inability to castle kingside.

I also agree that with 11...Nd7!, 9...Nc6 works out well too.

Lev, you are slipping into non-chess mode again.
Here is where I stand at the moment:
[1 d4 d5 2 e4 dxe4 3 Nc3 Nf6 4 f3 exf3 5 Nxf3 e6 6 Bg5 Be7 7 Bd3 Nc6 8 0-0 Nxd4 9 Kh1 Nc6 10 Qe1 h6]

11.Be3 Bd6 -/+ (Wollfelschneider - Behrendorf, corr 2003)
11.Bf4 Bd6 -/+
11 Bxf6 Bxf6 12 Ne4 Be7 13 Rd1 O-O! -/+ ( CraigEvans)
11.Qh4 Nd7 (other moves were suggested, but this looks most clear to me) 12.Bxe7 Qxe7 13.Qg3 O-O 14.Qxc7 Nc5 -/+

Can you show where I am wrong?

Markovich's suggestion 9...c5 10.Bxf6 Bxf6 11.Nxd4 (which I hadn't considered seriously) is probably White's best bet here, leading only to =+, whereas other lines tend to lead to -/+.   Thus, maybe 9...c5 is not significantly better than either 9...Nc6 or 9...c6 which also seem to be =+ with best play.

Quote:
For the time being I'll maintain my view that the Zilbermints Gambit offers interesting practical chances (and could be seen as a nasty trap, tempting Black to play 9...Nxf3) but with best play, is unsound.


I currently hold the same view, after looking over the various variations.  It isn't as bad for White as I'd previously assumed, but it's still objectively inferior to 7.Qd2, or 8.a3 or 8.Qd2.

Me too.

@Lev:  Thanks for all that analysis!  But I think you're way overestimating White's chances after 9...c5 10.Bxf6 Bxf6 11.Ne4 O-O 12.Nxd4 Bxd4 13.c3 Be5 14.Qc2.  White is two pawns down; two sets of minor pieces have been exchanged; Black has the two bishops; Black's position is completely solid; White's castled position is precarious.  Against this White has a slight surplus of development, but given the arrangement of the pieces, I'm not sure that he's much more active than Black is. 

Black has a wide and very pleasant choice of moves: 14...f5; 14...Bc7; 14...Qh4; 14...g6; 14...b6.  He even has 14...c4 which appears to compel 15.Be2 since 15.Bxc4 Qh4 18.h3 b6 looks way better for Black.  Provisionally I like 14...b6.  I'm just going to get my last minor piece out, so come and get me.

I like your 14.Qf3 better but even then I would much rather be Black.  There is also 14.Qe2 when I would probably play 14...b6.  14.Qh5 forces 14...f5 but after that it doesn't look very hopeful for White either.  If necessary, Black can part with his e6 pawn and still be winning.

For the time being I'll maintain my view that the Zilbermints Gambit offers interesting practical chances (and could be seen as a nasty trap, tempting Black to play 9...Nxf3) but with best play, is unsound.

[1 d4 d5 2 e4 dxe4 3 Nc3 Nf6 4 f3 exf3 5 Nxf3 e6 6 Bg5 Be7 7 Bd3 Nc6 8 0-0 Nxd4 9 Kh1 Nc6 10 Qe1 h6]
Markovich wrote on 03/15/11 at 19:33:36:
After 10...h6 White should probably play 11.Qh4.  Now 11...O-O?! looks pretty bad, while 11...Nd5 fails to untangle because of 12.Nxd5 exd5 13.Rae1 Be6 13.Qh5 and White has comp.  So Black can either give up kingside castling right away or temporize for awhile with moves like ...Bd7 and ...a6.  But either way, White can at least say that he has Black tied up for the moment.  Does White have sufficient comp?  I don't think so, but maybe someone can prove that he does.

Thanks for that! 11...Nd5 12.Nxd5 is a nice shot.
Here is another untangling proposal: 11...Nd7 12.Bxe7 Qxe7 13.Qg3 O-O 14.Qxc7 Nc5 with a fairly normal position with Black a healthy pawn up.

Quote:
Why is 9...Nc6 supposed to be such a red-hot move?  I would have thought that 9...c5 was begging to be played.  I don't think that exchanging on d4 and then on f6 gets White very much; I'll recapture with my g-pawn.  If 10.Qe1 then 10...Nxf3 11.Rxf3 Bd7 12.Rd1 Qb6.

I had thought about 9...c5, but (wrongly?) assumed it had been dealt with before. For now, 9...Nc6 still looks like an antidote to me.

I've had a thorough look at the Zilbermints Gambit, and get the impression that Markovich is right: 9...c5! (surprisingly not mentioned by Scheerer) is most critical, rather than 9...c6 or 9...Nc6.

I've attached a pgn giving some critical lines.  The key is that Black has to be prepared to give back one pawn in certain lines, and if 10.Nxd4 cxd4 11.Bxf6 then Black must play 11...gxf6! (when 12.Ne4 f5!? looks strong for Black in my opinion) instead of 11...Bxf6 12.Ne4 which leads to sufficient compensation for White.  Zilbermints's suggestion in UON #25, 10.Bxf6 Bxf6 11.Ne4, is best met by 11...0-0! when regaining one pawn with 12.Nxc5 allows Black to gain a large share of the initiative (e.g. 12...Nxf3 13.Qxf3 Qd4).

The lines 9...c6 and 9...Nc6 don't appear too bad for White- White's compensation isn't quite enough but Black's advantage is by no means decisive and there is plenty of scope for Black to go wrong.  If 9...Nc6 10.Qe1 h6 11.Qh4 then Black should probably play 11...Nb4 or 11...Bd7 followed by 12...Nb4 in order to untangle.



Looks like you guys will have to wait for UON #27 to officially come out. The editor-in-chief sent me the advance version, since it is dedicated to the Zilbermints Gambit. I sent him a lot of revisions, and since then I have not heard much from him.

Point is, 9...c5 is extensively analyzed in there.

1 d4 d5 2 e4 dxe4 3 Nc3 Nf6 4 f3 exf3 5 Nxf3 e6 6 Bg5 Be7 7 Bd3 Nc6 8 00 Nxd4 9 Kh1 c5 10 Bxf6 Bxf6 11 Ne4 00  and now:

12 Nxd4! is the key move.

Now the big question is: Which piece does Black capture the Nd4 with? There can follow three branches: A 12...cxd4; B 12...Bxd4; C 12...Qxd4

Analyses goes:

A) 12...cxd4 leads to a forced win for White. There follows 13 Nxf6+ gf6 14 Bxh7+! Kh7 15 Qh5+ Kg8 16 Rf3! ++-

B) 12...Bxd4 13 c3! Now the question is: How should Black play? There are four possible answers: B1) 13...f5; B2) 13...Be3; B3) 13...Be6; B4) 13...Be5

B1) 13...f5!? Attempts to strike back, but it fails a bit short of the mark. There follows 14 cd4 fe4 15 Rf8 Qf8 16 Be4 and now:

(1) 16...Qf4 17 dc5! Qe4 18 Qd8+ Kf7 19 Rf1+ Kg6 20 Qe8+ Kh6 21 Qf8 Kg6 22 Qe8+ Kg5 23 Qe7+ Kg6 24 Qe8+ Kh6 25 Qf8+ with a draw. If 16...Qf4 17 Qd3 Qh6 18 dc5 +=/+-

(2) 16...cxd4 17 Qh5! with at least a draw after 17...g6 18 Bxg6 hxg6 19 Qxg6+. If Black does not capture the Bishop, a White win is possible.

(3) 16...Bd7 17 dxc5 Rd8 18 Qc2 +=

B2) 13...Be3?? 14 Nf6+! gxf6 15 Bxh7 Kxh7 16 Qh5+ Kg8 17 Rf3 e5 18 Rxe3 Re8 19 Rd1 Qc7 20 Qh6 Bf5 21 Qxf6 Bg6 22 Rh3 Bh7 23 Rdd3 ++-

B21) 13...Be3 14 Nf6 Kh8 15 Qh5! Bh6 16 Rad1 Qe7 17 Nxh7! ++-

B3) 13...Bf6 14 Nf6 gf6 15 Bh7+ Kxh7 16 Qh5+ Kg8 17 Rf3 Re8 Qh6 ++-

B31) 13...Bf6 14 Nf6 Kh8 15 Qh5! Bh6 16 Rad1 Qe7 17  Nxh7! ++-

B4) 13...Be5 14 Qc2! This move frees the d-file for the Rook, while making a Queen-and-Bishop battery on the b1-h7 diagonal. The other move, 14 Qf3!?, is also possible.

C) 12...Qxd4  again leads to a forced win for White. There follows 13 Nxf6+! gf6 14 Bxh7+! Kxh7 15 Qh5+ Kg8 16 Rf3! Re8 17 Qh6 and wins. If Black plays 16...Rd8! then 17 Raf1 Kf8 18 Rxf6! wins again; 16 Rf3! Re8 17 Raf1 e5 18 Rxf6! Be6 19 Qg5+ Kf8 20 Re6 and White wins.

The sub-variations after 12 Nxd4! clearly illustrate White's practical chances. Of course, you have to know the analyses. But hey, that is true about every chess opening.

Having said that, here are the extant games with 1 d4 d5 2 e4 dxe4 3 Nc3 Nf6 4 f3 exf3 5 Nxf3 e6 6 Bg5 Be7 7 Bd3 Nc6 8 00 Nxd4 9 Kh1 c5 10 Bxf6 gf6


Zilbermints - Patrick Schoupal, BDG Euwe Defense Zilbermints Gambit Match, 27 August 2005:

11 Nxd4 cxd4 12 Ne4 Bd7 13 Qf3 f5 14 Qh5 Qb6 15 Ng5 Bxg5 16 Qxg5 Qd6 17 Qf6 Rf8 18 Rae1 Qe7 19 Qxf5 000 20 Qa5 Kb8 21 Qe5+ Ka8 22 Qxd4 Bc6 23 Qf2 Qg5 24 Re3 Rd5 25 Rg3 Qe5 26 Re1 Qd6 27 Rf3 f5 28 Rfe3 e5 29 Bxf5 Bd7 30 Rf3 Bxf5 31 Rxf5 Rxf5 32 Qxf5, Black forfeits on time.

By the way, your suggestion of 9...c5 10 Bxf6 Bxf6 11 Ne4 00 was first tried in Bernard Riepe - Christian Koch, DESC email tournament, correspondence, Germany 2001. In that game, discussed in UON #27, White played 12 Nxc5?! and 0-1/41 moves.

I assure you, I have a very good collection of Zilbermints Gambit games. This collection is renewed every time I find new games that were played with my gambit.

Thanks for that.  Yeah, 11...gxf6 as I mentioned before.  An interesting line is 10.Nxd4 cxd4 11.Bxf6 gxf6 12.Ne2 Qb6 13.Nxd4 Bd7 14.Qg4 O-O-O and Black appears to be significantly better.

I hadn't thought of 10.Bxf6 Bxf6 11.Ne4, but had only considered 11.Nxd4 Bxd4 =+.  Your 11...O-O does indeed look best, when I would much rather be Black.

Lev, what do you have against 11...O-O?

Actually I suspect that Black is also good after 9...Nc6 10.Qe1 h6 11.Qh4 Kf8 intending Kg8, but why take chances?

Dear Bonsai,

Thank you for having the courage to try the Zilbermints Gambit. I should point out that your opponent played the 9...c5 line, the Counter-Strike Variation. At a glance, the mistake that you made is with the 10th move. Instead of 10 Qd2, 10 Ne5, 10 Qe1, which are all inferior moves, correct is 10 Bxf6 or 10 Nxd4. This was covered exhaustively in Unorthodox Chess Openings #25, October 2009.
More coverage was in BDG World magazine.

With regard to your first game, I have not had the chance to look at it in detail yet. I am in a rush to catch the local bus, so will have to respond later. In fact, I am analyzing this blindfold! Thank God I memorized the analyses against 9...c5 line!

Keep up the good work. Who was your opponent? When were these games played? Take my advice, Bonsai, and go over my articles. You will be able to beat the 9...c5 line quite easily. I know I did.

Lev D. Zilbermints

Since Lev's problem is a lack of blitz games, because he cannot look at anything that's not been played in a blitz game, I generated some 3 min + 1s/move blitz games for him. Trying to play this as white I had a horrible time and lost 4/4, really it does not seem like a good practical try, although one might have hoped some of my cheapos might have worked.

Trouble is, after 10...h6 11 Qh4 Black might be tied up in knots. This is all the more true when Black does not have computer assistance.

The game below validates Markovich's assessment of the Knight exchange being bad.

You seem to think that there is an antidote to the ZGED, but there is not one.

Untrue.

Wollfelschneider - Behrendorf
Correspondence, Germany, 2003

1 d4 d5 2 e4 dxe4 3 Nc3 Nf6 4 f3 exf3 5 Nxf3 e6 6 Bg5 Be7 7 Bd3 Nc6 8 0-0 Nxd4 9 Kh1 Nc6 10 Qe1 h6

11 Be3 Bd6 as played in the game, 11 Bxf6 Bxf6 12 Ne4 Be7 13 Rd1 0-0! and 11 Bf4 Bd6 all seem to favour Black.

Here is an antidote.


After 10...h6 White should probably play 11.Qh4.  Now 11...O-O?! looks pretty bad, while 11...Nd5 fails to untangle because of 12.Nxd5 exd5 13.Rae1 Be6 13.Qh5 and White has comp.  So Black can either give up kingside castling right away or temporize for awhile with moves like ...Bd7 and ...a6.  But either way, White can at least say that he has Black tied up for the moment.  Does White have sufficient comp?  I don't think so, but maybe someone can prove that he does.

Why is 9...Nc6 supposed to be such a red-hot move?  I would have thought that 9...c5 was begging to be played.  I don't think that exchanging on d4 and then on f6 gets White very much; I'll recapture with my g-pawn.  If 10.Qe1 then 10...Nxf3 11.Rxf3 Bd7 12.Rd1 Qb6.
