1win Private Club #1 CS2 Predictions: Quarterfinal Pick'ems Preview

1win Private Club #1 Joins the CS2 Upcoming Tournaments Circuit

1win Private Club #1 runs September 25 to 28 in Belgrade, Serbia, with a $100,000 prize pool on the line. Organized by BASED Esports, the event brings eight rosters into a single-elimination bracket, with every quarterfinal played as a best-of-three. It slots into a busy stretch of CS2 upcoming tournaments, sitting alongside Stake Pulse Beat II and CCT 2026 Europe Series 9 on the September calendar, but the $100,000 purse and the LAN setting make it one of the more meaningful stops of the month.

Four quarterfinals open the event on September 25, and GoCore's Pick'ems platform has all four locked in for predictions before the first round starts. Here is how each matchup shapes up.

Alliance vs Sinners Esports and Ninjas in Pyjamas vs 3DMAX Predictions

Alliance opens the day against Sinners Esports at 09:00. Alliance has sat around the top 20 in the world for most of 2026, built around Sean "eraa" Knutsson and Liam "MaiL09" Tügel, and enters as the nominal favorite.

Sinners, the Czech org fielding MoDo, beastik, kisserek, SHOCK, and stressarN, had to fight through the closed qualifier just to reach Belgrade. That path through adversity is exactly the kind of form indicator worth weighing here, and the pick for this matchup is Sinners to close it out.

Ninjas in Pyjamas and 3DMAX follow at 12:00. NiP arrived with a direct invite, while 3DMAX pushed through qualification with momentum behind them. Recent tournament runs have favored the team playing with less pressure, and 3DMAX gets the nod to advance.

magic vs EYEBALLERS and GamerLegion vs K27: Best CS2 Players Clash

The 15:00 slot pairs magic against EYEBALLERS, a roster that added Freddy "KRIMZ" Johansson back in June, reuniting him with Jesper "JW" Wecksell for the first time since their back-to-back Major wins together in 2015.

That chemistry angle makes EYEBALLERS a compelling watch, but magic's recent trajectory carries the edge, and the pick here goes to magic in three.

GamerLegion closes out the quarterfinals against K27 at 18:00. GamerLegion sits marginally ahead in the world rankings, but K27 arrives having ground through their own qualifier gauntlet just days before Belgrade, a run that included wins over WW and NMG. Ranking gaps this small rarely hold up against a team playing with recent competitive reps, and K27 is the pick to pull off the upset.

Every one of these matchups can be locked in on GoCore before the September 25 opening round, with all four quarterfinals playing out across the same day in Belgrade.

With four best-of-three quarterfinals on one day and two live upset picks in the mix, 1win Private Club #1 opens with more unpredictability than its $100,000 pool might suggest. The semifinals and grand final on the following days will tell how much of this opening round holds.
