I don't know about 1. e4 c5 2. Nf3 Nc6 3. b4 but 1. e4 c5 2. a3!? which has been mentioned in this thread is pretty deadly and against it I always play the coward move2...g6 which makes the move a3 look a little awkward.
  

Don't listen to what I just said, I'm just a patzer pretending to know something.

why is this to be preferred to some the actually wing gambit though? Something like e4 c5 b4 cxb4 a3 e6 axb4 Bxb4 c3 Be7 d4 looks far preferrable to me than anything mentioned on the Portsmouth so far.

I mean honestly I want to have compensation for the pawn not just a bunch of tricks and traps even the most unprepared opponent can easily avoid as long as its not blitz.


The point is that with the black knight on c6 the advance d4-d5 is more powerful. Therefore unlike the original Wing Gambit the Portsmouth Gamibt offers more chances to gain the initiative.



There I completely disagree.  e6 can be played to prevent d4-d5 in the portsmouth which is a disgusting pawn advance anyways because of the gaping hole on e5.

In the actual wing gambit I still have my cpawn so I can play c4 forcing d5 late in the game when its useful. Plus I'd rather see black play Nbd7 uncoordinating his pieces, what will he do with the Bc8 bishop now? Lets not forget this line I posted is like an improved Evans gambit cause I already have an active rook on a1! Where in the portsmouth line the rook is useless on a1.

I don't see any compensation in the line you posted and would never play it. While the line I posted.... I play all the time beating many experts with it.


I agree that 4. ... e6 is a serious test to White´s ambitions, but it certain doesn´t refute the Portsmouth Gambit. See:

5.d5 (Worth trying is as well:

a) 5.Bd3!? d5 6.Nbd2 Be7 7.e5 Nh6 8.Nb3 Nf5 9.g4 Nh4 10.Nxh4 Bxh4 11.0-0 f6 12.f4 0-0 13.Be3 += Hansson,D – Niklasson,C, Sweden 1976, 1:0,19.;

I would like to see the BCCA article! I believe the analysis i'm referring to on d4 immediately I got from chesspublishing.


I am very interested in this article, too. Can someone post it here or at least tell where it is availabe?

Huh? Care to explain why? Big comment, no moves. Elaborate please....

btw

e4 c5
Nf3 Nc6
b4 Nb4
c3 Nc6
d4 d6

may be a tough nut to crack (and not mentioned in the BCCA article).

Rest is quite good fun.

The point is obviously c3 to kick the knight, then d4.

Mildly diverting article in BCCA mag last year or the year before.

Still not much cop really.

After 1.e4 c5 2.Nf3 Nc6, 3.b4 is garbage. After 3...Nb4 4.d4, Black should play not 4...d5?! but 4...cd4! 5.Nd4 (5.c3 dc3 is just too generous) 5...e6 and we have a Taimanov where Black has his knight on b4 instead of c6, and White is down an important pawn.

That's even less compensation than after 1.d4 e5 2.de5 Nc6 3.Nf3 Qe7.
  

All our dreams come true if we have the courage to pursue them.

I am playing this one for over 20 years now and found it quite playable especially in blitz and rapid games. One main advantage is that this line is nearly totally ignored by official chess theory. So the white player´s knowledge of this gambit ist clearly superior. Sure, the are some lines which are critical and pose problems to get full compensation for the sacrified material (e.g. 1.e4 c5 2.Nf3 Nc6 3.b4 Nxb4 4.d4 d5 5.exd5 Qxd5 6.Be2 cxd4), but there are many traps for Black which have to be avoided. For example, after 1.e4 c5 2.Nf3 Nc6 3.b4 cxb4 4.d4 d5 5.exd5 Qxd5 6.c4 bxc3 7.Nxc3 Qa5 it would be a blunder to play 8.d5?! because of e6. But this move is hard to find for an unprepared player, and i experienced that most oppenents can´t resist to play the tempting 8. ... Qxc3+, after which Black is lost.

Ianto, do you know why this one is called Portsmouth Gambit? And it would be nice if you could tell me where to get the articles by Barden and Clough mentioned in your posting.

The Portsmouth Gambit 1.e4 c5 2.Nf3 Nc6 3.b4 !
This is not an a3 Gambit !!!!#@$ Please
if black plays 3...Nxb4 the idea of this Gambit is to play 4.c3 (not 4.a3)
then when black plays 4...Nc6 (note the Knight has moved twice and is on the same square it was on , on move two) then white plays 5 d4
now if 5...cxd4 6 cxd4  white has two central pawns and open lines, in compensation for the pawn.

Try Dobrov-Aroshidze, Kavala Open 2004.
  

The book had the effect good books usually have: it made the stupids more stupid, the intelligent more intelligent and the other thousands of readers remained unchanged.
