Evans Gambit rocks.

This is such an unusual gambit, and if black grabs that pawn and doesn't know what he is getting into, it can be curtains in seconds...

White must use his tempo effectively though. If he plays slowly he will lose the game as he is materially deficit, and it is difficult to regain. If he plays quickly and hurries black along, he will have a fine fine game.

Yeah, I don't think I am advanced enough to come across many players who wouldn't accept this, and I don't think I'm prescient enough to exploit the tempo gained in an effective enough manner.

^^because the gambit gives material for tempo and development black doesn't have to accept it.

La he jugado con blancas, y me ha resultado muy buena. Solo hay que evitar la tentativa de jugar Pa4 ya que la respuesta de las negras es Pa5.

When I come across this gambit, I accept it.

if black takes the pawn, white get a strong centre with c3 and d4 and then the queen gets to b3. If a player dont know this theory, he gets a  difficult game

i dont like this variation

he declined the gambit

Why did the bishop move to B6 when it could have taken the pawn in b4
