In regard to the Tennyson gambit, I really am not certain how to play it so if someone could provide input, that'd be great. Also, how would one play 2. Nc3 against Scandinavian after 2. ... d4?
1 e4 d5 2 anything other than exd5
I only play this stuff in blitz, so it's "prepared" sort of... but not very seriously hehe. Here's what I do anyway

What would you play after 1 e4 d5 instead of 2 exd5
NOTHING!
2.exd5 Advantage White
2.Nc3 Equal at best
2.Anything Else Advantage Black
Plain and simple! 2.exd5 ONLY MOVE!

Tips for posting dubious gambits:
1) Assign at least one "!" to the dubious move (or moves).
2) Post a game where the opponent defends very poorly and loses before move 20.
3) In analysis, never, never, never show the best moves against the gambit.
4) Don't show the best moves against it.
5) DON'T SHOW THE BEST MOVES AGAINST IT.
6) Argue against anyone and everyone that it's a good opening choice.
Like the fool that posted the Tennison Gambit?
1.e4 d5 2.Nf3? (forget dubious, it's just outright bad!) dxe4! 3.Ng5 e5!! 4.Ngxe4 f5!! 5.Ng3 Bc5!! -+

I used to play d3, but then I got bored. I used to be normal, but then I got bored too. All kinds of boring things lately.

_+ seems off, like .4 - .5 in blacks favor. And I prefer Nf6 as the last move. But yeah, black is MUCH better there

No, that is not what I say. I say that , imho , lot of players would score better with BDG than the "traditional" openings.
And, for me, at least give much more fun games
I understand exactly what you are saying.
You are saying a very controversial statement about players in the region of 1400-2000 based on your own personal opinion.
I simply disagree with you.
I think people score wonderfully with "Traditional" openings.
They are called "Traditional" for a very good reason.
No doubt, that positional players in this range can score wonderfully with the Queens Gambit, but why do so much people doubt, that tactical players kareldevries or me, can also score wonderfully with the BDG?
It isnt a "must do" to play traditional standard openings...

Chivas,
I will follow 011's rules:
you are asking for rule number 3 and 4
After 4 .. Bf5!!!!
the best option for white is
5 g4 Bc8
6 g5 Ng8
7 f*e e6
white will need all the luck of the world to draw
5.g4 is not a good choice in this variation, 5.fxe4 is much better in my opinion, Black is under pressure from the beginning and has to play very carefully, otherwise he will get crushed.

I am not sure if you read what Kareldevries said.
Thus, I will post it below in green so you can see what he said.

^^ Mind you the ranking range he was using was 1400-2000 which is what he had stated previously.
The issue I have was with his assumption that players between 1400-2000 would score poorly vs the BDG.
What statistics is he using to support such a statement.
Perhaps my English is bad but I have more the idea that you want to read what you want to read.
Asking for statistical proof in a post where I use imho is a bit strange.

I read everything you said.
You said an opinion nothing more!
Telling people in the range of 1400-2000 that they are better off with the BDG vs Traditional opening is a bit strange!
So what is your problem with me having an opinion you don't agree ?

So what is your problem with me having an opinion you don't agree ?
My problem is when you tell other people in the range of 1400 to 2000 that they can do better playing the BDG vs Traditional Lines.
I believe saying stuff like that can be misleading to people.
A lot of title players tell players to play Traditional lines.
Now you are telling them not too!

The only defense to e4 is Nf6, the sicilian (sadly I dont care Fischer used it), caro kann, or any other "classical defense" can't stand against the development of a knight on the first move.
according to that logic, a knight simply can't stand against the storm of pawns (e5 Nd5 c4 Nb6 d4)
