B Main Pop Flash from B Ramp

Steps

1. From B Ramp, walk up toward the transition point where B Ramp opens into the B Main approach. Stand at the left edge of the corridor, pressing your left shoulder against the wall.
2. Look toward the B Main entrance at roughly head height. Find the top of the doorframe that marks the entry from B Main into the site area.
3. Place your crosshair on the upper-left corner of the doorframe - right where the frame meets the ceiling on the left side.
4. Start running forward toward B Main and perform a right-click throw (underhand) while moving. The timing should feel natural - throw as you begin your forward movement.
5. The flash bounces off the doorframe and pops almost instantly inside B Main, blinding any CT holding the angle. Because it is an underhand throw while running, the flash pops with almost zero reaction time for defenders.

Tips

• Pop flashes are the most effective entry tool in CS2 because defenders have almost no time to turn away. This underhand throw pops within a fraction of a second of appearing in the CT’s field of view.
• The right-click underhand throw is key - a left-click overhand throw would send the flash too far past the doorway, giving defenders time to turn away.
• Your entry fragger should be right behind you, ready to swing into B Main the instant the flash pops. Coordinate by calling “flashing, go go go.”
• If the flash pops too late (after the doorframe, giving CTs time to react), you are throwing it too late in your run. Release the right click slightly earlier.
• Practice this lineup offline with sv_cheats 1; sv_infinite_ammo 1; sv_grenade_trajectory 1; sv_grenade_trajectory_time 10; mp_roundtime_defuse 60 to perfect the timing.
• This flash does not require a jump throw bind, but you need to master the run timing. Practice the run-and-throw motion repeatedly until it feels consistent.

When to Use

This pop flash is a key T-side entry tool for B site on Ancient. Use it for:

• B Main entries where your entry fragger needs CT defenders blinded before swinging through the doorway
• Fast B executes where your team rushes through B Main and needs an instant flash to overwhelm the site defenders
• B Main picks in default rounds where you want to flash and peek for a quick kill on the B Main defender
• Anti-stack plays when you suspect CTs are stacking B site and need pop flashes to equalize the numbers disadvantage
• Force-buy rounds where your team commits to a fast B push and the pop flash is critical to winning the initial gunfight
