Good openings for 1100 to 1600

 - Put (and usually maintain) a pawn in the center
 - Develop pieces
 - Castle
 - Attack one of your opponent's center pawns with a pawn of your own
 - Try to infiltrate into their side of the board

That's basically how it works.

 I  cant recommend certain openings for your level specifically , coz I play on Lichess and I am rated about 1500 to 1600 ,  but i can recomment some dynamic openings 

For white - 

Italian game - basically 2 mainlines , against the Giuocu Piano(3. Bc5) , go for the Evan's gambit , and against the 2 knights , u can try some scotch gambit lines and the deadly nakhmanson gambit.

Jobava london system - Check this out as well , But i have not played this opening  but u can try it out .                       

For black  -

Sicilian is the first thing that comes to my mind , try any of those sicilians , the O'kelly is the easiest to learn imo but not good as a main weapon but just gain some experience and then start playing other sicilians like the dragon and other stuff .  ( All world champions and grandmaster atleast have one type of sicilian defense in their repertoire)                                                           

Against d4 , I highly recommend  the Kings Indian Defense and the Grunfeld , but they are so theoretical , so I recommend playing the dutch defense , which is quite and rare , and it has 3 branches in it (Classical , Stonewall and the Leningrad dutch) , in that u can choose whatever u like and just crush everyone with it .                                                                                                 Hope it works and have fun

Have a look on here and look for something you like the look of. 

I don't know about 1100 to 1600, but good openings are:

Against e4 - the French.

Against d4 - Budapest gambit

As White, the London System.

Here - you don't play any flank / modern / hypermoden opening, so it's Much easier. That's what I play. good luck all :-)

llama47 is correct, but I suspect you wanted some name openings. If you want to play aggressively and dynamically I would recommend the following:

As white: 1.e4 and various semi-solid gambits. Gambits tend to have a rating expiration, but the more solid ones can definitely be played at your level (and 500 points above) without damaging your chess. Avoid anything that is overly trappy and instead try ones that go for quick development and sustained initiative. As examples Smith Morra and King's Gambit are two that come to mind. To succeed as a gambit player requires aggression and utilizing the quick development. 

As black: Sicilian is generally considered the most aggressive response to e4. A lot of intermediate players seem to enjoy the accelerated and hyper-accelerated dragons. Against d4 the Gruenfeld is very complicated but extremely dynamic and aggressive. Nimzo would be another option is you don't want to take on the insanity of the Gruenfeld. Against c4, e5 for a reversed Sicilian. Against anything else put your pawns in the center and play like white. 

You'd like the book "Alterman's gambit guide".

Gives the repertoire Evan's gambit/Smith-morra gambit/Milner-Barry gambit/Panov-Botvinik attack

But it's not really a repertoire book. It's about teaching attacking chess by using gambits. It's a fun read.

Really good book.

Chess Opening Recommendations

You might give the Vienna Game & Gambit a try. This is an aggressive, attacking opening which is very popular at the amateur level, and playable even by advanced players.

For an aggressive opening for White against the Sicilian Defense (1.e4 c5) I suggest to check out The Grand Prix Attack. 

In particular you will notice that White's first several moves in the Grand Prix Attack are the same as for the Vienna Game & Gambit (1.e4 / 2.Nc3, followed soon thereafter by f4). While the openings are different by virtue of Black's first move, because White's first few moves are typically the same in both openings, there is some commonality not only in the setup but also in the fact that in both openings White's intention is to launch a kingside attack against Black, which is the point of the aggressive placement of the f4 pawn.

Because of these similarities what one learns in terms of tactics and strategies from one opening may sometimes prove useful for the other opening as well. At least this is my view, and why I chose to create blog articles on these two openings.

For beginner-intermediate players I also suggest to check out GothamChess (IM Levy Rozman) on YouTube for recommendations and quick tutorials on other openings....

For more opening suggestions check out the chess openings tier lists videos by GM Hikaru Nakamura and IM Levy Rozman (aka 'GothamChess').  There are separate tier list videos for beginner, intermediate and GM level.  Within a video each opening is ranked in terms of its appropriateness vis-a-vis player skill level.  Here is part 1 of the 3-part Tier List for Beginners...

Note also that (particularly for the beginner openings video) they will frequently refer to some openings as "garbage" or "bad" (an unfortunate choice of terms in my view). However, these qualifiers are meant simply to convey how appropriate the specific opening is for the level of player being discussed, in terms of, for example, how much so-called "theory" (i.e., documented variations) the opening encompasses, or how much emphasis the opening places on positional versus tactical skills in order to play it well.

So, an opening they refer to as "garbage" for a beginner may in fact be appropriate for higher rated players who typically know more of the theory for particular openings and have a more highly developed understanding of positional concepts. For each of the openings discussed be sure, also, to pay attention to whether the evaluation is from White’s or Black’s perspective.

Finally, several articles on suggested openings and other articles on chess topics that may be of interest to the improving chess amateur in my blog....

As black defend 1 e4 e5 and 1 d4 d5, as white open 1 e4.

indeed. It seems to me that you are actually very tactically alert but play very defensively (but actively) as white & black. Why would you want to go against your style of play to something "aggressive " n "dynamic "? I dunno.

also, playing only Rapid games kind of deludes one into thinking it's only the Opening that gives Good to Bad results. Your style of " go-with-the-flow" is pretty practical (to me). I think the Caro•Kann Defense may just be suited to you methinks. Just sayin 😎. It's pretty Practical n Solid as well, th
