CS2 lineup compilation videos have a real problem: they dump forty lineups per map on you, and most players learn none of them properly because there's no prioritization. A handful of grenades get used every single round on every rank. The rest are situational at best. Learn the handful first.
Smokes that block key sightlines beat smokes that look impressive
The highest-value smoke lineups are the ones that block a single dominant sightline controlling an entire bombsite — not the ones covering the most map area. On most maps, this is one or two smokes per site that pros throw essentially every round because they remove a defender's ability to see the plant zone at all, not because they're flashy.
Molotovs for retake denial matter more than execute molotovs
New players over-index on offensive molotovs for site executes and under-practice retake molotovs that clear a defuser off a plant. A well-timed molotov thrown the instant you hear a bomb plant, landing on the exact defuse spot, wins rounds your team would otherwise lose to a clean retake — and it's one of the highest-leverage, least-practiced lineups in most players' arsenals.
Flashes need to be popped, not thrown blind
A perfect flash lineup is worthless if you throw it without communicating the timing to your team, because a flash that isn't followed up immediately just warns the enemy someone's pushing. Learn the lineup, then practice the callout — "flashing in 3, 2, 1" — as part of the same muscle memory. Teams that execute flashes with timing win far more duels off them than teams that just spam grenades and hope.
Learn from your own position, not a generic spawn
Most lineup guides show the throw from a fixed spot near spawn, but real rounds rarely start you exactly there. Spend fifteen minutes in a private server practicing the same lineup from two or three realistic positions you'd actually be standing in mid-round — this is the gap between "I know the lineup" and "I can hit it under pressure."
The core fifteen, roughly
Across the current active map pool, focus on: the one or two dominant site-smokes per map that block a defender's main sightline, one retake molotov per site, one flash lineup per common execute you actually run with your team, and any smoke that blocks a common long-range angle you die to repeatedly. That's a realistic, memorizable set — not the sixty-lineup spreadsheet most guides throw at you.
The takeaway
Grenade lineups are a compounding skill, not a checklist — fifteen mastered lineups you hit under pressure beat sixty half-remembered ones you fumble in a real round. Start with sightline-blocking smokes and retake molotovs, since those affect round outcomes the most, and expand your list only once the core set is automatic.
