CS2 favourites betting strategy, backtested

Betting esports as one blob is a category error: CS2, Dota and League of Legends have different structures, metas and pricing quality. The first professional move is scoping to a single game, and that is exactly what this template demonstrates before adding the simplest possible signal.

How the filter tree works

• Group: only matches in the CS2 group qualify, filtering the esports feed down to Counter-Strike 2.
• Favourite side: the first-listed team must be the market favourite.

The group filter is the reusable lesson: any game title in the esports data can be isolated the same way.

What to watch

• CS2 rosters change constantly and patches shift the meta; six-month-old form can describe a different team under the same tag.
• Favourite prices in tier-one CS2 are sharp, while tier-two events are thinner and noisier; consider which events your sample actually contains.
• Upsets are structurally common in a game of pistol rounds and momentum swings.

Tweaks to try

• Add an odds range, for example 1.30 to 1.70, to define a playable favourite band.
• Add a best-of filter; favourites convert more reliably in longer series.
• Clone the template for another game group and compare markets.
