CS2 Round-by-Round Live EV Tracker — In-Play Advantage Model
Quantify true in-play map win probabilities and calculate exact mathematical expected value (+EV) against live bookmaker decimal odds during CS2 matches. Accounts for live score, CT/T map asymmetry, economy buy states, and MR12 overtime dynamics.

Round 13Frequently Answered Questions
How does economy state dictate single-round win rates? ▼
Empirical telemetry over 100,000 CS2 rounds indicates that a Full Buy holds an 82.4% win probability against an Eco, 71.2% against a Force Buy, and 51.5% in symmetrical mirror buys (adjusted for CT/T map bias). Betting live lines without factoring buy states leads to catastrophic EV erosion.
Why do recreational sportsbooks misprice defensive CT-sided comebacks? ▼
Recreational algorithms frequently extrapolate second-half momentum linearly. On heavy CT maps like Ancient or Nuke, an 8-4 T-half scoreline is standard. When the favored team switches to CT side, their round win expectation surges to 58-62%, creating massive +EV opportunities on underdog live prices.
How should Half-Kelly staking be applied to high-frequency live markets? ▼
Live esports odds fluctuate every 45-115 seconds. Full Kelly exposes bankrolls to severe drawdown during eco-round upsets. Half-Kelly (f*/2) preserves 75% of compound growth while restricting total bankroll exposure to sustainable 1-3% units.
