Win more on CS:GO's Inferno map as Counter-Terrorists

Inferno can be a tricky map to defend unless you understand it. To that end, start by learning the ‘call-outs’—the names used to describe each part of the map. This guide by Froosh and collaborators is a very useful resource to bookmark. Keep the Inferno image open in a tab as you work through the rest of this article.
There are two major chokepoints that you want to control: middle and top of banana. If you manage to keep the terrorists from pushing past these points until the end of the round you are likely to have gathered enough information to be ready for the final aggression.
At first glance this may seem simple, but if you have played a couple of games on Inferno you know that this isn't the case. One reason for this is the long rotations between the two bomb sites. As a consequence, you will have to slow down the terrorists.
Utility Grenades
Always prioritize smoke grenade, then two flashbangs. If you have money left you should go for an incendiary unless you plan to go for double grenades in either banana or middle to do some initial damage.
Having identified the problem, it's time to defuse it. In order to have a successful CT half you have to make the most of your utility grenades: don't throw away a flashbang for no reason.
Bombsite A
You want two guys to cover mid. Preferably one on arch side and one truck side. These guys will be your impenetrable wall. They will use their smoke grenades to ensure the terrorists won't be able to take over mid (at least not without begging for mercy when the rotation from B joins the party.)
You can use a flashbang to let your teammate peek and maybe even get a kill. If that player finds terrorists about to push mid he mustn't panic. Instead, you should just put down a smoke screen. Generally the player on the arch side should use his smoke first. That way you will still have smokes left on A if the arch player has to rotate to B.
The third player on A will make sure your opponents don't take control over apartments. This guy will be the James Bond of your team: the secret agent whose aim is to go for sneaky plays and catch the terrorists off-guard. If you have a smoke up in mid, the truck side player can support him from boiler stairs and let him hide in bedroom.
On the next page: control bombsite B, plus when to buy an AWP.
Bombsite B
On this site I like to have one highly confident player go a little more aggressive and peek angles. The other person gets to be the annoying devil who will make sure the attackers are so flashbanged they couldn't find a crater on the moon.
The first player can take a peek from the corner at the top of banana and try to spot terrorists. If they go for a fast push he can call for a smoke from the support player. If, on the other hand, he can hear them further down in banana or just wants to take a more aggressive peek, his ally can either flash over the roof or in front of the car as shown below.
If the guys on A need help it's best if the support player rotates if he has used his smoke already. Remember, clever use of utility grenades is what wins you rounds.
When the terrorists decide to commit to B they will almost always smoke off CT spawn. By this time it's likely that one of you will find yourself behind the grey cloud of death, but have no fear! Now you have two options. Either that player rotates around the construction site to spools or you can go for the ballsy play and flash pool so that the player from CT side can push the smoke and catch the enemies with their pants down.
AWP on Inferno
You have won a couple of rounds in a row and you find yourself with an abundance of cash. It's tempting to go back to the hotel and have a drink or two. Maybe buy something nice for you and your friends after a long day of combat. But no, now is not the time. There's still a war to be won. Instead you pick up the AWP.
Let's say your AWP player decides to peek banana and he ends up getting a kill. Then he can fall back towards CT spawn, lay down a smoke screen and switch positions with the guy on arch side on A. Often the terrorists will opt out and rotate back to mid, just to find themselves getting killed once again by the same AWPer. Note that this is a risky play and you should only use it once or twice.
Mix it up
Even though nothing can replace good communication and smart positioning you will have to mix it up a bit every now and then. After all, you don't want your opponents to read you like an open book. This is the time to use the card up your sleeve.
This flash from inside the corner on arch side is one of my favorite flashes in the entire game. Simply line up your crosshair with the line on the wall, flash, wait, and pick up some free kills.
Another high risk, high reward play is to let your support player hide behind sandbags. Peek banana from your usual corner and when you see a terrorist, just back off, call for a flash and then the two of you can spray them down.
Watch your Replays
Go to the 'Watch' tab. Then 'Your Matches'. Select the game you want to watch and click 'Download'. That replay will now appear in your 'Downloaded' tab. Click 'Watch on GOTV'.
Final words
Some of these things are easy to do and will help you win more games, whereas some things will take more time to master. Watch your replays (take a look to the right for instructions) and pay attention to what the enemy team did. Should you have rotated earlier? Later? Just remember, practice makes perfect: if at first you don't succeed, buy a defuse kit and try again.
