Please Experts+ : I need the most aggressive and complex d4 opening out there!

Also I never cheated in this website or any other. , as I'm doing this for myself and not to impress someone

The chess game of Mikhail Tal....study how he played against d4

When Kramnik was trailing against Leko in their world championship match he played the Modern Benoni.

Dutch

Benoni probably, hate playing it as white against good tactical players. Almost impossible to keep the position under control, usually ends up a horrid mess which I hate as am a bit of a control freak :-)

Well since you asked for experts I barely qualify as an expert by USCF standards(2000+ USCF) so I guess I can give advice on chess... and on grammar.

However, I feel like your post didn't really specify whether you wanted something trappy and cool while playing d4 or playing against d4. If you want something trappy and cool while playing d4, you should play e4 instead. If you want something trappy and cool against d4, then play the KID or grunfeld or Benko(depending on your level).

I hope this helps!

Sounds like the Benoni is what you're looking for.

Be aware that English is not my native  language, and I´m not an expert (only an online player).

Anyway.... here is my list: 

As white:

The only playable gambit that I know is the Blackmar Diemer gambit. (1.d4 d5 2.e4 dxe4 3.f3) is tricky but it is fully analysed

if You know the versov you can try other less common opennings like the trompowsky or the torre attack, but if  and  you have more time  try the  queens gambit complex (incluiding the catalan) 

As black: 

Gambits (tricky but more or less refuted)

Albin Countergambit  1.d4 d5 2.c4 e5

Blumenfeld Gambit 1.d4 Nf6 2.c4 e6 3.Nf3 c5 4.d5 b5

Budapest Gambit 1.d4 Nf6 2.c4 e5

Englund Gambit 1.d4 e5 2.dxe5 Nc6 3.Nf3 Qe7 4.Qd5 f6 5.exf6 Nxf6

Playable gambit:  

Benko Gambit  1.d4 Nf6 2.c4 c5 3.d5 b5

Dinamic and ambitious defences:

Benoni, KID, dutch and modern defence 

Forget tricky and trappy. If you are an inexperienced player you should begin with the solid Queen's Gambit Declined and study the games of old school players such as Capablanca and modern heroes like Kramnik.
