Inferno Smoke Guide: Banana, A Site, B Site and Retakes
Inferno rewards teams that understand space and timing. Many important fights happen around narrow entrances, which means one well-placed smoke can completely change who is allowed to move through an area. This guide explains how to think about Inferno utility around Banana, A Site, B Site, rotations and retakes instead of treating each smoke lineup as an isolated trick.
Why utility controls the pace of Inferno
Inferno contains several narrow routes where players cannot simply spread out and take independent fights. Banana, Apartments and the entrances toward both sites naturally funnel players into predictable areas. This makes grenades extremely powerful.
A smoke does more than remove vision. On Inferno it can deny a choke point, force a team to wait, isolate one defender from another or buy enough time for a rotation to arrive.
Good Inferno utility therefore starts with timing. A perfect smoke thrown too early may disappear before the attackers are ready to use it.
Use the round clock as part of your utility plan
Inferno utility has a strong relationship with time because so many routes are narrow. A smoke that delays a choke point when there is plenty of time left may be only a small inconvenience. The same smoke late in the round can force a difficult choice: push through with poor information, rotate, or risk running out of time.
Attackers should think about the clock too. If the team spends too long setting up a perfect execute, defensive smokes can become more powerful because there is less time available to wait them out. A practical utility plan leaves room for a second decision if the first route is blocked.
Banana control: fight for space before fighting for B
Banana is one of the most important areas on Inferno because controlling it changes the amount of information both teams have. If the CT side owns Banana, defenders can often keep more players available toward A. If the T side takes Banana safely, the defense must respect a possible B execute.
Use smoke to deny information
A smoke in Banana can prevent defenders from seeing how many attackers are present or whether the team has fallen back. That uncertainty has tactical value even when nobody immediately pushes through the smoke.
Attackers should still understand what they are gaining. If five players wait behind the smoke and do nothing, the defense may simply use the time to prepare.
Defensive Banana smokes
CT-side smokes can slow early pressure and make attackers spend valuable seconds before they are able to challenge deeper positions. The goal is often delay rather than a fight.
Saving a smoke for later can be equally powerful. A late defensive smoke when the round clock is low may force the T side into a rushed decision.
Banana control does not always require a site commitment
One of the strengths of Banana control is the information it denies. If attackers can hold the area without showing the full team, the CT side has to respect the possibility of B. That can influence how comfortably defenders rotate toward A even when the bomb is not nearby.
This makes a smoke valuable even when it never leads directly to a B execute. The grenade may have helped secure a forward position that keeps the defense uncertain for the next thirty seconds of the round.
B Site executes: separate the site from the rotation
B executes become easier when attackers reduce the number of defenders who can influence the entry at the same time. Common utility plans attempt to isolate the site from CT-side rotation routes or deeper supporting positions.
Once that separation is created, the entry players can focus on clearing the positions that remain visible rather than fighting the entire defense simultaneously.
Smoke is temporary control
A smoked rotation route is not permanently safe. Defenders can push through the smoke or wait for it to disappear. Someone on the attacking side should still understand who is responsible for watching that possibility.
Build B entries around what remains visible
A B execute should leave the entry player with a short list of priorities. If rotation support is smoked, the entry can focus on the site and close positions. If a deep angle remains open, another player should know that it belongs to them. Clear assignments reduce hesitation at the narrow entrance.
It is also worth practicing the moment after the plant. The smoke that helped isolate the site may soon fade, so attackers should already know which post-plant positions will watch the returning rotation.
A Site: Apartments and ground pressure must support each other
A attacks can involve several different elevations and entrances. Players coming from Apartments may threaten different positions than teammates approaching from the ground.
Smoke grenades are valuable when they isolate one part of this defense. If a defender can no longer support a teammate through a long sightline, attackers can create smaller and more manageable fights.
Do not hide the positions you still need to clear
A poorly placed smoke may protect a defender by giving them an unpredictable area to play around. Before throwing it, know which sightline should disappear and which part of the site your entry players still need to see.
Use Apartments pressure to change where defenders look
Apartments pressure is useful because it introduces a vertical and positional problem that ground defenders cannot ignore. Even when the Apartments player is not the first entry, their presence can change where a defender stands and which angle receives attention.
The best A utility plan uses this pressure intentionally. Smokes should remove support lines while the two groups reach fighting positions at similar times, rather than allowing one route to become an isolated duel.
Inferno rotations and fake pressure
Because the map contains narrow access routes, utility can create convincing pressure without every player committing. A smoke and supporting grenades may force defenders to respect one side of the map while the bomb remains elsewhere.
This only works when the utility looks believable. Throwing every grenade at one site and then waiting too long may reveal that the actual attack has not begun.
Retake smokes on Inferno
During a retake, think about the planted bomb and the post-plant positions rather than the original site entrance. The most useful smoke is often the one that removes the attacker's strongest line of sight toward the bomb.
Retake utility should also be fast. A simple smoke that can be thrown immediately is often more valuable than a precise lineup that consumes too much of the bomb timer.
Practice late-round Inferno situations
Do not limit practice to full-buy executes with every grenade available. Rehearse a late B hit with one smoke, an A retake with limited time, and a Banana re-take after early utility has already been spent. These situations reveal which lineups remain useful when the round is imperfect.
A lineup that requires a long setup may be excellent early but poor during a retake. Knowing that distinction is part of learning the grenade.
How to practice Inferno smoke lineups
- Choose one area. Learn Banana or one bombsite before adding more utility.
- Repeat the starting position. Use the same corner, wall edge or map reference every time.
- Verify the aim reference. Fixed geometry is easier to reproduce than vague descriptions.
- Confirm the throw type. Standing, jump and running throws produce different results.
- Check for gaps. Inspect the smoke from the defender's side.
- Practice what happens next. Move into the space the smoke was designed to create.
Common Inferno smoke mistakes
- Using utility too early. The smoke expires before the execute begins.
- Throwing without a purpose. The team loses a grenade but gains no space.
- Ignoring smoke pushes. Defenders can use the smoke aggressively.
- Blocking teammates. A misplaced smoke can remove a useful attacking sightline.
- Saving everything forever. Utility that dies with you has created no value.
Build an Inferno utility set around timing
A useful personal set should include at least one grenade for early control, one for a planned site execute, and one option that still works late in the round. This creates flexibility without requiring you to memorize every possible lineup.
As you add alternatives, organize them by purpose rather than by where you stand. "Late B isolation" is easier to remember in a match than a list of unrelated starting spots.
Practice Inferno with SmokeLine
SmokeLine separates each lineup into position, aim and throw references. Use the position image to reproduce the setup, the aim image to match the visual reference and the video to confirm the movement and final result.
Inferno smoke FAQ
What should I learn first on Inferno?
Start with utility for the area you play most often. Banana control and basic site-entry smokes are useful because they appear repeatedly in normal rounds.
Why are late smokes so strong on Inferno?
Narrow entrances make waiting expensive. A smoke placed when the round clock is already low can force attackers to push through it or abandon the plan.
Should every B execute use the same utility?
No. The correct utility depends on defender positions, available grenades and the control your team already has.
