Openings against e4 that are Open (except e5)

Does anyone know any openings against e4 that don't leave black with a cramped position but rather a more open position?

If you do not want a cramped position as Black, grab your share of the center while you can, and that is done with 1...e5.  Everything else (Sicilian, French, Caro-Kann) sees White get a space advantage.  Of course, having an advantage in space is not the only asset in chess.  Black usually has other trumps in those semi-open defenses, like better pawn structure, which usually makes most endings better for Black in openings like the Sicilian and French.

Is the Scandinavian opening a good choice or does that leave White with a space advantage

I think e4 e5 has a lot of theory to learn for black against the Ruy Lopez, King's Gambit, Italian Game, Scotch, Ponzianni, etc. I'd rather play a line that most players at my level don't know much theory about like the Sicilian, Scandinavian, French, or Caro-Kann. I have realized that I tend to thrive in positions where I have a more open position as I play better with Bishops than Knights.

Players tend to respond Nf3 then Bc4 against e5. Bb5 is played too though, but I prefer e5 against the Sicilian or Scandinavian tbh

I don't think that is sound at all

Holy crusader wdym?

I doubt that is a good choice against either the Sicilian or Scandinavian; it could lead to a superior position for black

Does the Najdorf or Dragon give black more space than the other semi-open defenses?

Around 2010, IM John Watson wrote, "... For players with very limited experience, ... the Sicilian Defence ... normally leaves you with little room to manoeuvre and is best left until your positional skills develop. ... I'm still not excited about my students playing the Sicilian Defence at [the stage where they have a moderate level of experience and some opening competence], because it almost always means playing with less space and development, and in some cases with exotic and not particularly instructive pawn-structures. ... if you're taking the Sicilian up at [say, 1700 Elo and above], you should put in a lot of serious study time, as well as commit to playing it for a few years. ..."

"Generally speaking, 'Starting Out' and 'Sicilian Najdorf' are not exactly words that one envisions in the same title, because anyone who is just starting out should not dive into the vast ocean of theory that is the Najdorf. For beginners, the time invested in studying even minor lines can be more productively used solving tactical puzzles and basic endgame technique.

...

... In some lines, a good understanding of basic principles will take you far, while in others, such as the Poisoned Pawn (6 Bg5 e6 7 f4 Qb6!?), memorization is a must, as one wrong move can cost you the game in the blink of an eye. ..." - FM Carsten Hansen (2006)

In 2014, Pete Tamburro wrote, "... You will see [in Openings for Amateurs] the reply to 1.e4 to be the great reply of the open games with 1...e5. The Sicilian Dragon is presented as an alternative. ... I have found that scholastic players take to the Sicilian Dragon very quickly. ... A cautionary note: the Dragon is good at club level, but as you start facing better players you're going to find yourself memorizing tons of lines and the latest analysis, ... From my experience with coaching players below 1800, you won't need to do that too much. ..."

"'Black proclaims by his symmetrical reply 1...e5 his firm decision to cross swords as quickly as possible with his adversary and (in spite of 'the move') to meet him on an equal footing in the centre of the board, whereas a passive reply such as King's or Queen's Fianchetto (1...g6 or 1...b6) would allow White to occupy the centre immediately and for good by 2 d4.'
'After the typical moves 1 e4 e5 we frequently see a lively struggle, seeking in particular to gain the mastery in the centre.'
'Each move in the initial stage must be telling, in other words, it must contain some threat of an immediate nature (attack on a pawn, an effective pin of a piece, unpinning, counter-attack, etc.), and a game of chess of this type resembles an encounter between two fencers where thrust and parry follow and offset each other.'
Savielly Tartakower (A Breviary of Chesss)
1...e5 is arguably the simplest and most logical reply to 1 e4, taking space in the centre and opening diagonals for the queen and bishop. It has been played by every world champion in the history of the game, and many of them played nothing else. ..." - GM Nigel Davies (2005)

I think my USCF rating is enough to handle the theory of the Sicilian since I played it for the 6 months that I have been playing chess. I just want a tactical, open position; preferably a Sicilian or Scandinavian. Any ideas? (I am okay with any position where black has a slight space disadvantage, but I want to have space to develop my pieces)

For example, a position where my BISHOPS have free diagnols

Is there any recommendations for an opening where my bishops have free diagonals. I am okay with white having more pawns in the center as long as my pieces are not forced to the 7th rank like in the Philidor. Can the Caro-kan, French, Sicilian, or Scandinavian work for this? If so, which variations

I am just asking which one of those do you think gives black a position where he can move his bishops freely
