The line is good for OTB games, but for internet or correspondence.What will you play against this ?
1.e4 d5 2.exd5 Nf6 3.d4 Bg4 4.f3 Bf5 5.g4 Bg6 6.c4 e6 7.g5 Nh5 8.Nc3 Be7 9.f4 .Despite this wide open position, white is a healthy pawn up and black his own weaknesses after all.

@ SWJediknight
I think it might be difficult implementing the 0-0-0 plan 
e.g. 3.d4 Bg4 4.Bb5+ Nbd7 5.Be2 Bxe2
a) 6.Qxe2 Nxd5 7.Nf3 e6 8.0-0 Bd6 9.c4 N5f6 10.Nc3 c6 (10...Qe7? 11.c5) 11.d5!
b) 6.Nxe2 Nxd5 7.0-0 e6 8.c4 N5f6 9.Nbc3 (9.Qb3!?) 9...Bd6 (9...c6 10.Bf4) 10.Qb3! Qc8 11.Ng3 c6 12.Nge4


Yes, it seems upon further reflection that White has too much ready-made queenside play.  In line b), Black should play 8...N5b6 instead as TN gave, and then his 9.b3 could be met by 9...Qf6 and 10...0-0-0, but it doesn't work so well against 9.c5 Nd5 10.Nf4, or 9.Nd2 Qf6 (not the best) 10.Qb3 0-0-0 11.a4 with dangerous play.

However the plan with ...Be7 and ...0-0 might come close to equality in those lines.

Again, after 6.Qxe2, although the queenside castling plan looked attractive on first sight, it seems White has too much queenside play: in your line it would be suicidal for Black to castle into the open c-file, while I looked at attempts like 7...N5f6 8.0-0 Nb6 followed by ...Qd7 and ...0-0-0 plus 7...N7b6 8.0-0 e6 9.c4 Nf6 10.Nc3 Be7 followed by ...Qd7 and ...0-0-0, but they both give White dangerous play while Black's kingside offensive hasn't even got off the ground.

Alternative approaches:  I see nothing but a riskless edge for White after 7...e6 8.0-0 Be7 9.c4 N5f6 10.Nc3 0-0.  The alternative is to continue with the plan of developing the bishop on d6: 7...e6 8.0-0 Bd6 9.c4 N5f6 and then after 10.Nc3, simply play 10...0-0 (taking the sting out of d4-d5) with the idea of ...c6 and ...Qc7 with possible counterchances.  White can play c4-c5 to chase the bishop back to e7, but maybe relinquishing some of the central control, particularly of the d5-square.

I still can't find any way for White to render the ...0-0-0 plan suicidal after the immediate 3.Bb5+ Bd7 4.Be2 Nxd5 5.Nf3 Bf5 (5...b5!?), where I don't see a way to stop Black continuing 6...e6 and then ...Nc6, ...Qd7 and ...0-0-0.

Maybe 4.Bb5+ Bd7 5.Be2 is the biggest annoyance after all?

In Watson's "1.e4..." column this month, Watson seems to have used some of the ideas from this forum (unfortunately I am not a subscriber to any of the sections). 

As it turns out, tipau was correct all along, as shown by the following quote from Watson:

"This <4.Bb5> is a very interesting approach, helping Black's development but hurting his piece coordination. My impression is that White retains a riskless edge, although Black's 'restraint centre' keeps him in the game, à la Caro-Kann. In the Forum, there are varying opinions of White's line. I agree with those who are discouraged by this move order; at any rate, Ahn-Rosse, Kallithea 2008, works out well for the first player."

I was also proven wrong regarding the 3.Bb5 Bd7 4.Be2 variation, as shown by the following comments by Watson:

"Similar but not quite as irritating is the sequence 3 Bb5+ Bd7 4 Be2 Nxd5 5 d4: Here Black usually plays 5...Bf5, but in Blesic-Karaklajic, Belgrade 2008, he uncorked the remarkable 5...b5!?. This prevents c4 and grabs some space, while weakening c5 and c6. Black eventually got the advantage, although White has plenty of options and it's too early to tell how 5...b5 will fare."

I also argued that "one rare line that is slightly better for White should not discard an entire variation for Black." This is once again proven wrong by Watson's publication of the game on ChessPublishing. Firstly, openings that give the opponent a 'riskless edge' are usually not ones that should be implemented. And secondly, if the rare lines work in the opponent's favour, then it is logical to believe that the main line will also be better for White.

Thanks to both tipau and Watson for correcting my misconceptions regarding this variation! Smiley

@ TN
I haven't played the Scandinavian (apart from the odd game or so) for a few years it's possible there's something new in this line I'm not aware of, but the latest knowledge of the 3.Bb5+ Bd7 4.Be2 line that I have is that after 8.a3 0-0 9.c4 Nb6 10.Nc3 Nc6 11.Be3 (11.h3 Bf6 12.Be2 is the same) 11...Bf6 12.h3!? 
(this stops 12...Qe7 because of 13.g4! Bg6 14.g5 winning the piece. If White plays 13.b3 Qe7 and if 13.b4 Bg4 - one game of mine continued 14.Ne4 Bxf3 15.Nxf6+ Qxf6 16.Bxf3 Nxc4 17.Bxc6 bxc6 18.Qc2 Nb6 {18...Nxe3 19.fxe3 Qg5 is possible} 19.Qxc6 Nd5 and it was soon a draw N.Rutter-T.Seymour, 2004)
12...Bg6
(This was mentioned by Emms in his 2nd edition Scandinavian book as possibly Black's best. I actually found and played it before the book was published, so it was nice to have it validated - not so nice that I knew I'd have less chance of surprising anyone with it again! The similiar line 12...h6 13.b4 e5! 14.d5 e4 15.Nd4 Nxd4 16.Bxd4 c6 17.Rc1 is also reasonable for Black in my opinion. Emms says White is better after 17...cxd5? 18.c5 but if Black instead keeps the tension with 17...Re8 and Rc8 I don't see why White is better)
13.b4 e5 14.d5
(14.dxe5 Nxe5 15.Nxe5 Bxe5 =)
14...e4 15.Nd4 Nxd4
(Emms only gives 15...Ne5 without comment but after 16.Qb3 White is playing c5 and looks good to me)
16.Bxd4 c6 17.Bxf6 Qxf6 18.Qb3 was A.Rawlinson-T.Seymour, 2004 and now 18...cxd5 19.Nxd5 Nxd5 20.cxd5 is if anything a little better for Black. Maybe White does better with 17.Rc1 but I'm still not really scared for Black.

Onto the 3.d4 Bg4 4.Bb5+ Nbd7 5.Be2 line. With regards to what you said about it in your first post, I think on the 6.Qxe2 line you said pretty much what I said in my first post (Black has a solid Caro-Kann type position). Maybe you are right and Black isn't so bad - possibly I just need to study these positions a little more to get a better "feel".

@ SWJediknight
I think it might be difficult implementing the 0-0-0 plan 
e.g. 3.d4 Bg4 4.Bb5+ Nbd7 5.Be2 Bxe2

b) 6.Nxe2 Nxd5 7.0-0 e6 8.c4 N5f6 9.Nbc3 (9.Qb3!?) 9...Bd6 (9...c6 10.Bf4) 10.Qb3! Qc8 11.Ng3 c6 12.Nge4

Any thoughts on the suggestion of Black's alternative queenside-castling approaches in the 3.Bb5+ Bd7 4.Be2 and 3.d4 Bg4 4.Bb5+ Nbd7 5.Be2 lines?  I'm prepared to accept that they aren't any good if that's the way it transpires, but I can't find any references to the idea anywhere- all the analysis I can find on those two lines (whether here or elsewhere on the 'net) takes as given that Black plays ...Be7 and castles kingside.

Alas it's only me who replies first.

TN: Thanks for investigating this line. However, I still don't think that your main line is sufficient for equality (according to my database White scores 65% after 8.a3 0-0 9.c4 Nb6 10.Nc3). Obviously statistics are not entirely reliable, but White's position does seem much easier to play.


Not only I think the same, I think this because of experience from the Black side. I have played the Kieler Variation (3.d4 Nxd5 4.c4 Nb4) a couple of times - really not as bad as theory wants us to believe - until I began to met 4.Nf3, which forced me to give it up (alas).

One of the main ideas of the Scandinavian (at least with ...Qa5) is to reach an 'improved' Caro-Kann with the c8-bishop outside the pawn chain at the expense of a couple of tempi moving the queen. 

Thanks for the advice. I suppose that explains why in the 5 years I played the Scandinavian I never played the ...Qa5 lines and always played for the Portugeese gambit instead.

TN: No worries. Smiley

Instead of 3.Nf3 Nd5 4.d4 Bf5, which scores quite poorly in the line you give, 4...Bg4 5.Be2 e6 is a more enterprising way to play. Objectively White is slightly better of course, but Black has decent counterplay.

I wouldn't call that enterprising. 4...Bg4 takes play back into regular 2...Nxd5 lines (as I mentioned in my original post). I think White is better there so as already discussed 3.Nf3 Qxd5 4.Nc3 Qd6 seems to be the best fitting line.

TN: I agree that the 4...Bg4 isn't really enterprising, but it is somewhat more active than the 4...g6 and 4...Bf5 variations. I see that we agree that White is better in all variations after 3...Nd5 though Smiley

I disagree that 3...Qd5 4.Nc3 Qd6 is the best fitting line - much easier and more practical to simply play 2...Qd5 3.Nc3 Qd6. But if you are referring to the best fitting line in the 2...Nf6 variation - then I agree with you. 

TN wrote on 11/10/08 at 07:29:39:
According to my reference database, 4.Bb5 is not as common as 4.Be2 and 4.f3, so I wouldn't ditch the Portugese Variation solely on the basis of this variation.

But it's legal and some people do play it I assure you. If there's a simple line which gives White an advantage (which may or may not be the case here) personally I think that's a good reason to not play an opening, regardless of how popular it might be.

TN: I retain my position that one rare line that is slightly better for White should not discard an entire variation for Black - particularly because White starts off with good chances for an advantage at the start of the game. See my comments below for my viewpoint on this variation.

I'm perfectly happy to play against this line and it was briefly discussed already. In the main line (4...Nxd5 5.d4 Bf5 6.Nf3 e6 7.0-0 Be7) Black's Nb4 ideas discourage c4, while if White plays a3 then c4 Black's light squared bishop is again very useful in pressurising the White centre (ideas of Bg4 and Bxf3 - after Nb6, Nc6 & Bf6). This is why 3.d4 Bg4 4.Bb5 Nbd7 5.Be2 is such an annoying line, the exchange of light squared bishops is useful for White and unlike 3.d4 Bg4 4.Be2 Bxe2 5.Qxe2 Qxd5 Black's queen is inactive so he is forced into a "normal" Scandinavian type position

I noted that you still find the 4.Bb5 Nbd7 5.Be2 variation 'annoying'. What improvements did you have in mind over my recommendations in my first post in this topic?

I admit that Black's position doesn't look very active at first, but these structures are fine for Black because of the exchanged light-squared bishops and the counterplay against the d4-pawn that I alluded to before. 

The conclusions I have drawn from this thread so far are that you are happy with the main lines after 3.d4 Bg4 (for example, you already said that you felt that the 4.Be2 Be2 5.Qe2 Qd5 lines are fine for Black, which I agree with) and don't mind transposing to 2...Qd5 variations with 3...Qd5 4.Nc3 Qd6, but are still dissatisfied with the Bb5 variations. I am not sure about how Black can equalise against the 3.Bb5 Bd7 4.Be2 variation, but I don't see why you should fear the 3.d4 Bg4 4.Bb5 possibility.

But I should give you time to reply first!

@Willempie 

You are correct, the bishop is developed actively in the Caro-Kann as well. 

What I should have said was that compared to the Caro-Kann, White knight is placed on c3 instead of e4 or g3, which makes it harder for White to support his central d4-pawn, and it is not so easy to find a stronger square for the c3-knight at first. For this reason, in some lines Black can obtain counterplay against the d4-pawn. 

@Mnb

Yeah, I agree that the c4 variations are not so easy for Black, although I haven't played them from either colour. When I said that the 4...Bg4 variation was 'enterprising', I was comparing it to Black's alternatives such as 4...Bf5 and 4...g6. 

I also prefer the ...Qd5 lines to ...Nd5, but then Black's 2...Nf6 move order starts to look a bit strange. It would be much easier to simply play 2...Qd5. True, White is committed to Nf3, but White usually plays this move at an early stage in any case in the 2...Qd5 Scandinavian.

On the basis of the points alluded to above, the main problem with the Portugese Gambit from a practical point of view seems to be not the opening itself, but White's option of avoiding it with 3.Nf3, when Black either has to accept a somewhat passive position after 3...Nd5 or learn the 2...Qd5 variation as well with 3...Qd5.

On a final note, the 3.Bb5 Bd7 4.Be2 also seems to be a hassle for Black if he is after active counterplay - unfortunately I do not have time to investigate this further at the moment.

Methinks that the c8-bishop is outside the pawn chain in the CK as well. Usually with less problems than in the Scandi as there it is often not sitting well on g4.
  

If nothing else works, a total pig-headed unwillingness to look facts in the face will see us through.

Because of 5.c4 and 6.c4 it does not make sense to combine this with the Portuguese. Moreover 6.0-0 Be7 7.Ne5 and it's White who plays enterprisingly.

One of the main ideas of the Scandinavian (at least with ...Qa5) is to reach an 'improved' Caro-Kann with the c8-bishop outside the pawn chain at the expense of a couple of tempi moving the queen. 

If you do like them, then the Scandinavian is a sensible choice of opening. 

Instead of 3.Nf3 Nd5 4.d4 Bf5, which scores quite poorly in the line you give, 4...Bg4 5.Be2 e6 is a more enterprising way to play. Objectively White is slightly better of course, but Black has decent counterplay. 

According to my reference database, 4.Bb5 is not as common as 4.Be2 and 4.f3, so I wouldn't ditch the Portugese Variation solely on the basis of this variation. After 4...Bd7 5.Be2 Be2 6.Qe2 Nd5 7.Nf3 e6 8.0-0, 8...Be7 9.c4 N5f6 10.Nc3 0-0 looks okay for Black - the position after ...c6 is very solid, and the exchange of light-squared bishops eases Black's defence. Eventually Black could either pressure the d4-pawn with pieces or gradually prepare a liquidating ...e5 break. 

6.Ne2 doesn't look scary to me - the following game is a good example:
[Event "Izmir GP op"]
[Date "2002.08.30"]
[White "Secer, Ata"]
[Black "Sayman, Umut"]
[Result "1/2-1/2"]

1. e4 d5 2. exd5 Nf6 3. d4 Bg4 4. Bb5+ Nbd7 5. Be2 Bxe2 6. Nxe2 Nxd5 7. O-O e6 8. c4 N5b6 9. b3 Be7 10. Bb2 O-O 11. Nbc3 Nf6      12. Qc2 c6 13. Rad1 Qc7 14. Ng3 Rad8 15. Nce4 Nbd7 16. Nc3 Qa5 17.

Thankyou for the replies.
I'm favouring 3.Nf3 Qxd5 4.Nc3 Qd6!? at the moment as MNb suggested. I've played this move in rapid games before and I have Melts' book so it shouldn't be too hard to work out some reasonable lines.

SWJediknight wrote on 11/08/08 at 16:55:01:

The line with 3.d4 Bg4 4.Bb5+ Nbd7 5.Be2 Bxe2 6.Qxe2 (or 6.Nxe2) Nxd5 is very reminiscent of 3.Bb5+ Bd7 4.Be2 Nxd5, but probably slightly more favourable to White.  Black normally continues with ...e6, ...Be7, ...0-0 and has a few Nb4-related tricks but generally White gets a slight, nagging edge.  But I wonder if Black can get away with a more combative approach, castling queenside and turning the game into an attacking race.  

For instance, 3.d4 Bg4 4.Bb5+ Nbd7 5.Be2 Bxe2 6.Nxe2 Nxd5 7.0-0 e6 8.c4 N5f6 9.Nbc3 Bd6 10.Ng3 Qe7 11.Qf3 0-0-0.  Similarly in the line 3.Bb5+ Bd7 4.Be2 Nxd5, how about 5.d4 Bf5 6.Nf3 e6 7.0-0 Nc6 (instead of the theoretically recommended 7...Be7 8. Re1 0-0) 8.Bd3 Bxd3 9.Qxd3 Qd7 10.c4 Nf6 11.Nc3 0-0-0.

Yes I agree it's a favourable version for White of 3.Bb5+ Bd7 4.Be2. I used to find that line difficult but after it was recommended in Emms' Attacking with 1.e4 I spent a lot of time looking at it, and was eventually very happy to play against it.
At first look I like your idea of castling queenside against 3.d4 Bg4 4.Bb5 Nbd7 5.Be2, I'll certainly give it some more thought.

Why not start by looking up all of Laylo's Scandanavian games, if he plays it half as often as mentioned in the update then he must have encountered quite a few of these alternative move orders.

That was the first thing I did but unfortunately, in my database at least, Laylo doesn't have any games in the line 3.d4 Bg4 4.Bb5+ Nbd7 5.Be2 and against 3.Nf3 he's played 3...Qxd5 4.Nc3 Qa5 once (2005) and 3...Nxd5 4.d4 Bf5 the other three times (2006-7). Only one of his 3...Nxd5 4.d4 Bf5 games continued 5.Bd3 and he seemed happy to accept a small disadvantage, then gradually outplayed his opponent.

I played the Portugeese (1.e4 d5 2.exd5 Nf6 3.d4 Bg4) for a long time but eventually gave it up a few years ago for several reasons. One reason was that White seemed to be doing very well in the critical 4.f3 lines, but the last 1.e4... update shows a new very interesting idea for Black that I quite like. Because of that I've recently been re-investigating the other lines and wanted to see if anyone here had any ideas on them:

The two main issues I have are:
1) 3.d4 Bg4 4.Bb5+ Nbd7 5.Be2 Bxe2 6.Nxe2 (or 6.Qxe2 Nxd5 7.Nf3 e6 8.0-0) 6...Nxd5 7.0-0 e6 8.c4 N5f6 9.Nc3 c6 White seems to have a nice position. I suppose it's nothing too special, but I never feel too comfortable in these Caro-Kann-ish type positions.

2) 3.Nf3 and now 3...Qxd5 4.Nc3 (4.d4 Bg4 is back in the Portugeese) gives a normal Scandinavian after 4...Qa5 or 4...Qd6, or 3...Nxd5 4.d4 when 4...Bg4 or 4...g6 will transpose to the normal 2...Nxd5 lines and 4...Bf5 (which I usually played - and I've noticed GM Laylo also plays) 5.Bd3 Bxd3 6.Qxd3 e6 7.0-0 gives a similiar situation to problem 1.

Do people think Black has good equalising chances in these lines?

After 3.Nf3, 3...Bg4?! is worth a try at fast time limits and/or low levels, as it gives some practical chances, although it probably isn't wholly sound.   Michael Goeller's is perhaps the most thorough analysis:
http://www.kenilworthchessclub.org/articles/opening/anti-port.htm

Otherwise if you want something sound then 3...Qxd5 is the way to go as MNb states above.

The line with 3.d4 Bg4 4.Bb5+ Nbd7 5.Be2 Bxe2 6.Qxe2 (or 6.Nxe2) Nxd5 is very reminiscent of 3.Bb5+ Bd7 4.Be2 Nxd5, but probably slightly more favourable to White.  Black normally continues with ...e6, ...Be7, ...0-0 and has a few Nb4-related tricks but generally White gets a slight, nagging edge.  But I wonder if Black can get away with a more combative approach, castling queenside and turning the game into an attacking race.   

For instance, 3.d4 Bg4 4.Bb5+ Nbd7 5.Be2 Bxe2 6.Nxe2 Nxd5 7.0-0 e6 8.c4 N5f6 9.Nbc3 Bd6 10.Ng3 Qe7 11.Qf3 0-0-0.  Similarly in the line 3.Bb5+ Bd7 4.Be2 Nxd5, how about 5.d4 Bf5 6.Nf3 e6 7.0-0 Nc6 (instead of the theoretically recommended 7...Be7 8. Re1 0-0) 8.Bd3 Bxd3 9.Qxd3 Qd7 10.c4 Nf6 11.Nc3 0-0-0.
