After 1. e4 d5 2. exd5 Nf6 3. d4 Bg4 4. f3 Bf5 5. Bb5,
What is the best continuation for black? I was looking into some articles claiming that 3...Bg4 is a good move, but nothing was explained about this continuation.
Does this line refute 3...Bg4? Or is there a good continuation for black?
That variation is complete garbage for black. There are a few good ways to play for black but you must either play: 1.e4-d5 2.exd-Nf6 3. d4- Nxd5 or Qxd5 are basically the only real ways to play for black here.
"Refute" is usually taken to mean "prove that it loses," and that isn't exactly the case here. So it may not be "refuted" but still be "complete garbage for Black" since he has much more reasonable attempts at his disposal.
If White says "A" with 4 f3, he may as well say "B" with 5 g4 Bg6 6 c4. 5 Bb5+ does put the pawn in the bank, but it also forces Black to develop. Better to give him room to go wrong in choosing how to develop with the annoying pawn on d5.
Alright, thanks for the help.
I think that I'll just forget about the scandinavian. It's too unorthodox for my liking, thanks for the help.
I have written a blog post on this opening:http://blog.chess.com/view/why-i-stoppend-playing-scandinavian-2-nf6
c6 is a decent option to block the check and close the position on the queenside, but I would suggest going with Nc6 in the true spirit of rapid development that the Portuguese is all about. Eventual plans for black will be Qb6 to hit the bishop and shift the action to the opposite side of the board, followed by a possible 0-0-0 to put pressure down the d-file.
