(SORRY I DON'T REALLY KNOW HOW TO DO THIS) De-aztec is a semi-popular - popular map. It's a bomb defusion map, and counter-terrorists probably have the upper hand.
Counter-Terrorists
Being a counter terrorists is pretty easy, if you have a good team and a scout, or even better, an AWP. You can camp or rush. For camping, camp in either: The blocks near the bomb site for the big one near the double-doors, or right behind the block in bomb-site A, or the block near bombsite A, at/near the CT buy zone. To rush, call 40% of your team to charge the double-doors. A few Ts should be there, and if you are playing against bots, 70% of the terrorist team should be there. Then, call 40% of your team to go down into the water. They should meet some terrorists there. The other 20%, the nooblets, should camp at bomb-site A and/or B (yes, this is out of the topic, but it still works.) OR at the bridge, where they should meet the other noob terrorists (I'm talking from experience; when I was a nooblet, I always used the bridge). The people at the bridge should meet up with the other people, or "backstab (shoot in the back) of other terrorists if the 40% charging at the double doors are not done killing the group. Near the end of the campaign, when there is one person left, everyone should go in groups of two to kill the remaining survivor.
Terrorists
There aren't many tactics here. Camping is not recommended, since there isn't much to camp for, so we will use rushing. For terrorists, rushing is simple. Just rush in one, big, fat group. It is recommended you rush: over the bridge, or in the water. The T doors don't give much of a good angle to shoot at, unless you were a sniper and you had a AWP, allowing you to shoot at people at the bomb B site. Another way is that you can all rush at the bridge. After rushing to the middle, jump into the water so you don't get hurt. Then make your way into a site, preferable site B, since you could go to site A from the bridge. This is where camping is useful; camp at the places a CT would camp.
Weapons
This isn't really a place for short range weapons, like a shotgun. However, if you are a person good with shotguns (like me, I get headshots with shotguns at long-range with a 1% chance =]), use it. If you are flexible with all weapons, go snipe. Otherwise, buy a automatic rifle. SMGs are not recommended, unless you are SUPER poor. There is a tactic that you could use. First, at the buy zone (this is for CTs), buy a flashbang and a TMP. Make your way to either the bridge, or the double doors (this can also be used later in the game). When you see an enemy, take out your flashbang and throw it at them while not looking at the flashbang. THROW IT DIRECTLY AT THEM. Then, using the silenced weapon, shoot them. They will not know where you are, since the weapon is silenced and the flashbang deafens your enemy. Make short work of the terrorist. hold your trigger-finger if they are SUPER close, otherwise, shoot in bursts. However, the TMP doesn't have much of a recoil (I think, so I think you should spray and pray.
Conclusion
As you can see, de_aztec is a good place to go for people of all kinds, besides noob shotgunners or noob machine gunners. Also, the map is pretty simple; its just a place with a bridge, a canal, and stairs (a man, a plan, a canal, Panama)(use that if you can't remember anything, lol =]). Go there to practice your sniping skills if needed. Or, you can just go to www.csnation.com (I think that was the website) and install an AWP map. That sums it up. I hope you enjoyed this guide, and feel free to edit it, as long as your extra stuff can help people.
