Budapest Gambit

"WHAT IF AFTER 3.......NG4 THEY PLAYED 4 F3"
Then black snatches the pawn back with NxPe5.

In the lines given by  Graw81, what about playing 6. Pc5. If the bishop moves then you get to exchange queens, stopping black castling. 

 I assume you meant 15...Bxg5 (see diagram, benws). 16.Qh5+ attacks the weak white squares. For example: 16...g6 17.Bxg6+  hxg6 18.Qxg6+ Ke7 19.Rf7+ Ke8  20.Rxg7+ Kf8 21.Qf7#.  On the reply: 16...Ke7 the mate is quicker (17.Rf7+) using the same pattern. Possible is: 17...Ke7 Bxg5+, and this is also futile for Black.  The move 15.Ng5 was a Greek gift.  

So I can show a game in a botched up Sicilian that White won and then discredit the opening all together?  We are not saying that the Budapest wins every time, we are saying that it is a good weapon for tactical and dynamic players.

 6.c5?! White should be thinking about developing pieces insted. After 6...Nc6 (developing with tempo) white must move the queen again, perhaps to c4 where black will play ...Be6 again developing with tempo. Black will get lots of compansation for the pawn after 6.c5?! White cant play 7.Qd1 either because 7...Nxf2 is on. If white checks: 7.Qe4+ the bishop simply drops back to e7. White behind in development. Black player would be happy with this position i imagine.

On 4.f3. I dont know the idea behind this move at all. First of all, it blocks the f3 square on the knight, although the knight could develop Ng1-h3-f4 or something. After e4 whites light squared bishop will be bad so another pawn on light sqaures dont help at all. Black just simply captures the pawn and if white plays passively he will give up any hope of an advantage in the opening. White would be better to play 4.e4 followed by 5.f4 (not f3 where the knight can sit on e5). White simply has a better game in other lines and has more active resposes.

I presume you mean BxG5. QH5+ then eith KE7 or G7 leaves black with difficulties.

I like Fajarowitz variation.

I recently have been doing a lot of work in the Budapest Gambit.  I originally played it four months ago and then shelved it later when I was playing in tournaments.  But lately, I need something with winning chances against the weaker scholastic opponents.  I am finding that even against superb and best play by White, Black has counter-chances and will even get an edge if he knows the ins and outs of the position and White does not.  I would like to continue this forum and ask that we debate the merits of the Budapest Gambit.

I gave the Fajarowicz Variation of the Budapest Defense a try in a couple of games I won one and I am losing the other, but in both games the opening selection wasn't the deciding factor.

Black looks in a MUCH better position in BOTH games.

on move 3 try ... Ne4-it's called the Fajorowicz and it's a lot of fun.

Yeah.  I messed around with it for a little while, but decided that it was not a sound or solid as the mainline Budapest.  Definitely playable, though.

The Budapest Gambit used to be my main defense to 1. d4. I have quite a bit of analysis on it, but nowadays I prefer QGA because it gives Black more counterplay.

Players who like the Budapest Gambit: What else do you recommend preparing against White's move 2 when they don't play 2.c4?

@36

When white plays 2 Nf3 then there is no Budapest Gambit.

My question wasn't very clear; let me expand.

I enjoy playing the Budapest Gambit, so against 1.d4 I play 1…Nf6, hoping for 2.c4. However, in many games White plays a different second move, such as 2.Nf3, meaning I can't play the gambit. Budapest Gambit videos always feature deviations from move 3 but never (?) give ideas on what to do if White's 2nd move is not 2.c4. I wonder what most Budapest Gambit players do in such circumstances. Presumably, they choose something that's somewhat similar in spirit to the Budapest Gambit?

@38

"they choose something that's somewhat similar in spirit to the Budapest Gambit?"
++ There is no such thing. 1 d4 Nf6 2 Nf3 and now
2...b6, 2...b5, 2...c5, or otherwise transposing 2...d5, 2...e6, 2...g6
There is no good option but transposing to something you did not intend to play.

It is the same with the Albin Countergambit: 1 d4 d5 2 c4 e5, but 2 Nf3 stops it.

The Englund 1 d4 e5 allows the e5, but is even less sound.
