has anyone heard of the halasz gambit?

the halasz gambit can crush any sicillian defence varioations do you agree if you heard of this gambit?

I've heard of it, and ventured it in bullet chess, but weather or not it can crush any scicillian?? I have no idea. Actually I find the idea dubious, but apparently it orginiated in correspondence chess, so it can't be too bad.

Edit: fyi: 1. e4 c5 2. d4 cxd4 3. f4

sorry to contradict myself but the actual halasaz gambit goes
1. e4 e5 2. d4 exd4 3. f4

and according to Tim Harding (Chesscafe.com) people have been trying it with some success against the siciillian as well.

It occurs 18 times on my database, and scores an impressive 79%, and 11 of the games were correspondence games played by G. Halasz. He won all his games but 2.
