Scandinavian Richter V Wing gambit

Das cray

Is there any sharp lines in this? I have a bad engine so its hard for me to tell, if white plays slow he seems to have a large advantage, but what if he makes some inaccuracies? any crushing lines? thanks.

2. ... Nf6 is the Marshall Gambit, with three main lines, 3. Bb5+ ( very quiet ), 3.c4 and 3. this d4, mostly followed by 3. Nxd5, what after 4. c4 and Nb4 is called the Kiel Variation.

Most sharp line could be 3. c4 c6 4. dxc6 Nxc6, Marshall's idea.

Do you ask the question as white or as black ? Apparently as black, and when you choose for Nf6, you play a gambit, offering to give up material for a better position.   3. c4 is very natural, but let somebody else judge about b5, I don't know...

Please reformulate your question, by "slow" you mean defensive ?  And of course you have to take advantage of inaccuracies !

im aware of this. Can you see the diagram? I was particularly asking about The The move ...b5 in the richter variation ..g6 of the mainline d4 of the modern scandinavian 2...nf6 that occurs in the scandinavian e4 d5.

does that make it clearer?

For the BDG to pose any threat whitemust make accurate moves to keep his initiative going. I doubt anyone i play who just uses it against the scandinavian will know very much theory on it. So its a free pawn.

Three assumptions in one sentence :D 

On a serious note though, a Master friend of mine who plays the Scandinavian says the only crushing lines are with 2. ... Nf6 or 2. ... Qd6. 

I used to main it against 1..d5 as white. So I was probably playing 2.e4 in 1/3 of my white games. Even after playing a lot of games with it, the theory moves are so exact and difficult to find I probably wouldnt have had much success with it outside of correspondence.
Someone who ONLY uses it against the scandinavian probs plays it like 1/15 games as white, so it is very unlikely they will be able to learn the theory to any decent degree when they get such little practice.

Do you mean 3..Qd6?

From what I understand, 2...Nf6 (1.e4 d5 2.exd5) is under a big theoretical cloud right now and still hasn't come back.  3...Qd6 is under a lot of pressure right now.  3...Qa5 requires very exact play as there have been recent games which have completely smashed black or take him out of his game completely.

If you put the work into the Scandinavian Defense, then it certainly can be a good defense for black.  It just has a multitude of move orders which can make the difference between equality and a major disadvantage.

true, but its fun and I dont think the disadvantage it brings is big enough for the opponents I play against to capitalise upon.

If i ever get to a point where im losing games because I come out of this opening in bad positions, ill switch to the alekhine. The modern scandinavian is just a convenient way to reach some alekhine like positions, since it avoids all the sidelines like 2.nc3, 2.d3 and the KIA, which are boring to play against.

As for the BDG, just play the Ziegler Defense (1.e4 d5 2.d4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 c6) which follows similar to the main line Scandinavian with an extra pawn to boot.  There are a few lines to keep in mind, but study those and you should be fine.  Example:

I can't stop laughing at this.

The standard Ziegler (if arrived at via the BDG accepted) can also be met with 6.Bd3 which potentially offers a second pawn but with complications, and it avoids the refuting old main lines of the Ziegler defence.

In order to prevent that Bd3 curveball, black has to play the O'Kelly defence, which declines the gambit on the fourth move. The O'Kelly defence avoids the Bd3 complications, and forces White to play Bc4 in the Ziegler if he intends to continue with his gambit. Although, White is not obligated to do so. He could just as well take his pawn back and seek a drawish position. If he wishes to continue attacking, the Alchemy variation is the line you should prepare for.

Against 3.d4 Black has a sharper (and in my opinion, better) option - 3...Bg4: the Portuguese Gambit. Depending what White does afterwards, play is often similar to the Icelandic Gambit or it can transpose to positions in the Qa5 line.

The Portuguese is considered playable for Black and it's used at all levels. There is no clear refutation although the Bb5+ line is damn close. It is a minefield for Black though so you need to know it inside and out. One weak move can lead to disaster very quickly. It's one of those kinds of openings. Yeah... have no illusions about it if you plan to get into it. With that said, I see zero point playing the Nf6 Scandinavian if your intention against 3.d4 is Nxd5. Sure, if you like giving White all the winning chances and being in a horrible, almost-lost position, go right ahead. I figure if you chose to play the Nf6 Scandi you are hoping for either the 3.c4 c6 or 3.c4 e6 gambits, in which case the Portuguese is probably closer to the type of gameplay you'd prefer compared to 3.d4 Nxd5.

Yup, the Portuguese is "fine". White has scored just a measly 76% after 4.Bb5+.

There is also Moritz Wind's idea:

This has been played half a dozen of times at correspondence chess the last five years, and Black scored a remarkable zero points... very impressive.

Well yes. 8...Nh5 is a blunder. One would expect that after Nh5 White should win every time. I can see why it has only been tried 6 times.

No, it isn't. Black just has not enough for the material he's about to shed.

8...Nd7 looks "better": After 9.Nxd5 Nc6 10.h4 white's score is just 90%. So, the Portuguese is very promising, if Black does not mind losing.

Well, if a single-digit number of games is a rigorous enough sample volume for you, then you'll be happy to know that this line is 'refuted' by 7...Be7 with 100% of the 1 games played from that continuation being won by Black.

And of course we have the sodium attack, which is truly broken and wins by force for white, according to the 4 games on ChessTempo.

Well statistics aside, the position just looks like a pawn down without compensation.

I thought there were some recent developments on the Portuguese in chesspub that made it just about playable.  

These games are from players rated between 2100 and 2350 on correspondence servers, which means that they both used their best engine for a couple of days to check each move.

When you are referring to 7...Be7 you are missing one game- here:

Both games with 7...Be7 aren't terribly good, which fits perfectly with the value of that move. White looks much better after 8.h4, which certainly makes more sense than the 8.de6 which was played at the Olympiad game you mentioned.

Anyway, I see no evil in playing crap openings- quite the opposite: When you lose, you can always blame it at the opening. Under that aspect, the Portuguese is just perfect.

The portuguese is very bad, read any scandinavian book which features 2..nf6 and they will tell you. Even a book entirely devoted to the portuguese variation says in the introduction, "the portuguese is trash, but at least its fun to play", or something along those lines.

Anyway white can avoid it and go back into mainlines, so whats the point of learning it?
