“A dream becomes a goal when action is taken toward its achievement”

The Danish gambit is a favorite weapon of the attacking player at the club level. In OTB (over the board) accepting it could cause a lot of pain to the defending side. Surprisingly it also works in online play. I say surprisingly because one could assume in online play Black has more opportunities to study it. That can be done within seconds after finishing such a game. In reality not many bother to do that.
When facing a gambit, a simple way to deal with it and cause discomfort to your opponent is to reject it. A player decides to play it to have an attacking game, possibly leading to a quick win. Seeing the opposition not accepting it, should be a downer. This is also true for the Danish gambit. I thought bringing back to the forefront an interesting way to decline it, could be of interest.
It is not every day when a line resists the test of time. The players in below game are legends and their game has been replicated a few times over the years. You might expect regular players to follow this. The truth is grandmasters did it on a couple of occasions, so there is no reason why you should not try it out as well:
Showing just the above game did not feel enough. I looked a bit more into it and found below game. In it Black wanted to see if the 2 connected passers on the queen side would help playing for a win. After losing them, he also tried to grind down his opponent in a long endgame. Possibly the 200 FIDE rating points difference was a strong incentive. Still the result was the same. Now there is no excuse to at least give it a try or even use it as your main weapon against the Danish.
