play the closed. 2.nc3 or tennsyon gambit.

Nc3 black will reply d4. What is tennsyon gambit? Nf3?

yes

d4 ncd2 

u can play that if you like the closed positions.. It will sometimes leads to kingside attacks by white 

by an eventual f2-f4

thats all i know. welcome

I pretty much always get a +0.7 advantage against the Scandinavian in practical play because usually black doesn't know what he's doing in the opening. Not that the Scandinavian is a terrible opening but you have to know what you're doing with black to try for equality. I learned using Victor Bologan's chessbase DVD which was very good and explained a number of key ideas. He basically recommends the main lines. As far as the lines I think you're referring to here are a couple variations that might help:

8...g5 the Queen has an escape square 9.Bxg5 Ne4

Then Bxg5, either the queen's going to drop or White has a huge attack with the Queen out of play.

I like 3 Nf3 because a lot of players like to attack the pawn on g2. Nf3 discurages some tricky mate threats. After that play d4 and then Nc3.  I don't like h3 as a solution to the pin. Just let that pressure simmer for a while. At some point you can move queen to d3 to protect the knight and remove the pin. 

Some Scandi players are awesome and really tough to beat but I feel good when I see it played because the above works for me. 

Good Luck

Qd8 is 0% a problem to play against. Qa5 and Qd6 is the problem- Usually it seems castling on Qside is better if black Does 0-0-0

Woah! Seems good to try in a blitz game strangemove but after Qc5 what is white's compensation?

Rb3 with Ba3 ideas. Big development lead, difficult for black to castle. In blitz/bullet you could even try Rb5. It's all very unsound against good black play but white is having all the fun.

Opponent played like a squashed cabbage leaf in fairness but I guess he didn't know the variation. Anyway it shows black must be careful.

Nc3 is interesting especially if Black answers d4 which is supposed to give equality. However that line is not as bad as it looks like. Reminds me of the 2 knights in the Caro-Kann where Black plays d4 closing the centre and getting mated,  but Nf6 as my canadian coach said would transpose into an Alekhine altough Im not sure exd5 is the best there.
