a new line in the Daeth


Doubt it. No way he could resist to play that opening....
Even if he did resist that temptation it would be easy recognize the way he talked here. Way too many people know him. He would be like a drop of white paint on a black surface here.

With all these current weak threads his is left here would easily been the most interesting. Which is not saying much about the current threads in public forums.

Your not fooling anybody at all.
Your approach to this is not even close to Daeth.
Even a person that read his comments for week would not be fooled.
Daeth already found all the lines he needed so their is no new line plus several titled players here already checked it and the conversation/debate went into details. It was already shown that it was not original and used several times. Plus even he had to admit the only real strong point is if your opponent was caught off guard. Why he had problems here because too many members are booked up at chess.com.
Besides why say you are him? Chess.com is not going to waste much time to verify. They will just take you at your word and remove you from here.

Why do all Daeth players insist that black should play 2. ...Bf5. He should just play 2. ...c5 with an improved Queen's Gambit, since White has wasted time and weakened his Kingside with 2. h4?

Who is this 'death' anyway
Daeth. A dingaling who started ridiculous threads to tout an idiot line: 1.d4 d5 2. h4.
After several challenges by various people to demonstrate it, it turned out that he used a computer to play games with it against his hapless victims. So ultimately, he was tossed from the site.
It is suspected that he is back in another guise.
Here's my farewell thread:

Who is this 'death' anyway
His user name .... Daeth not the other way around.
HIs opening had one use as a surprise. If i entered a blitz tournament i would use it but have to use it in the first game as some players have 1st game jitters even if they are good. Beyond that it is useless.
I tried it out at another site (2 min game) as they never saw his thread here. Result was 2 games 2 wins and i put it away forever as i expect it will get around to the other players and they will be prepared for it.
It does have a fun factor if playing with a friend in a series of games. Could be used as a tool against a new player also. As unexpected "Unorthodox Moves" early would give them problems. They learn to find the weakness then find a way to exploit and then follow it up to the Middle Game to the End Game.
