Openings to play for intermediate players

yeah, but e4 openings have a lot more variance as you cannot play the same way no matter what you opponent responds with, unlike a d4 system (obviously there are exceptions)

All of my 100% accuracy games have begun with 1.e4, but I favor 1.d4 in OTB.

i think I can safely assume nobody has ever played a 100% accuracy game lol

also, I'm probably gonna sound stupid when I ask this, but what does OTB mean???

OTB = over the board. That is, face to face in the flesh.

I’ve had at least a dozen 100% games. The only ones with Black have employed the Stafford Gambit.

wow...that's insane 

Now I know i guess 

My last 100% accuracy was a Fried Liver against a beginner.

Chess Openings Tier Lists – GMHikaru (complete, beginner thru GM)…
https://www.youtube.com/watch?v=M9CwH47r6og&list=PL4KCWZ5Ti2H43-gcoByRnZs5fVR_Lg133&index=4

In the tier lists (above), chess openings are classified in terms of their appropriateness vis-a-vis player skill level -  i.e., beginner vs intermediate vs GM, etc.  For a given player level, the openings are rated and categorized into six "tiers", from "legendary" to "garbage" (the latter word being an unfortunate choice of terms, IMO).  These qualifiers are used in the context of not only how much so-called "theory" (i.e., documented variations) the particular opening encompasses, but also how tactical versus positional in character it tends to be, which is generally dictated by how "open" versus "closed" the center is at the conclusion of the opening.  Openings with less theory to learn and which are primarily tactical in character are generally recommended as an appropriate starting point for less experienced players.  So an opening they refer to as "garbage" (i.e. less 'appropriate' - a better term!) for a beginner may in fact be more appropriate for higher rated players who are assumed to possess a more highly developed knowledge base and skills set.  For each of the openings discussed note also whether the evaluation is from White's or Black’s perspective.

Not up to your usual standards.

If you recommend to play the exchange french as white then I have lost my hope for humanity

When I have Black, the French Exchange is cowardly. When I have White, it is a useful tool.

As Jan Pinsky said of the Four Knights, you can beat a GM with it, but first you have to bore him to death.

To be fair its really up to you if you want to have a snoozefest in Italian. Giuoco Piano is boring there is no doubt. Pianissimo is even more boring. But there are also stuff like Greco attack and Evans Gambit. Though, its boring if your only option to sharpen it up is gambiting a pawn.

Ruy Lopez is good, both sides always walk on razors edge, even if Berlin defense is on the board. It doesn't matter at our level.

Lol i guess boring the opponent to death is one way to wear them down

Exchange French underrated 

Exchange French boring as heck

Sure the board is immediately put into a symmetrical position, but both sides have interesting and dynamic setups they can go for. White also wants to avoid the main chunks of prep black has.  White can make things interesting using the c4-break and going for piece activity, most notably opening things up for the bishops. The game will also likely go into a opposite side castling situation. 

Thank you everyone for telling me about various openings and your views regarding it 

I would say Scandinavian or queens gambit works
