as our esteemed friend Markovich would probably tell you, if you're 1500-1600, you should be less concerned about understanding pawn chains in closed positions than about understanding tactics in open positions.
if you like the open games as black, awesome. i started playing the tarrasch as black in an attempt to get to open positions, but the problem with the tarrasch is that everyone from 1200-2200 has memorized the rubinstein plan with g3, etc, and bangs out those moves instantly, getting into a low risk position. instead, you can try something like the albin, which i think is good for an attacking player, or the tartakower, which was once a main weapon for attacking players like spassky and kasparov.
the maroczy is a very positional opening. if you like to attack, probably not the greatest choice. big difference between attacking the king and trying to keep your c4 pawn alive. there are many more tactical ways to approach the sicilian.
there are lots of nice attacking options against the french and caro. respectable mainlines against both give white an initiative, and there are other options like the alekhine-chatard, milner-barry, etc, etc. i like the panov-botvinnik against the caro, and i also like to play exd5, c4, against the french, even though maybe it's not as objectively strong as main lines. i always thought that it was pretty easy for white to get an attacking position against the french, especially against the 1500-1600 crowd, it's not the easiest defense to play. just peek in a database or a collection and see if you can find something you like.
our friend Markovich would also point out that if you have no intention of seriously improving your play and are happy playing for fun, you can play anything, play the hippo, play 1.a3, whatever. but if you are trying to improve your play, you should strive for tactical open positions, and choose openings that lead to those types of positions.
once you can occasionally outplay a master-strength player in an open position, then it's time to concern yourself with positional niceties. until then, tactics is your first name, tactics is your middle name, tactics is your last name. breakfast, lunch, dinner. and the best way to learn tactics is in open positions.
Markovich has seriously gotten into my head...
