BREAKDOWN · MODEL ANALYSIS

The model makes M. Kostyuk the favorite with a 85% win probability, against K. Sebov's 15% — a conviction read: the model sees the match clearly leaning one way. Converted to odds, that probability is worth about @1.18; the offered odds are around @1.05 (a 95% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #13 vs #231 (better ranked); 8/10 in recent matches; 1-0 in favor; 26d vs opponent's 7d.

Read it with perspective. Our probability is calibrated — when the model says 85%, that outcome happens roughly that percentage of the time, with ~64% out-of-sample accuracy — but being the favorite is not being the winner: roughly 15 out of every 100 times Sebov wins. The model also tends to agree with the market, so the odds already capture almost all the edge: don't take it as a sure value. Watch out for: Returning from a long layoff (26d) — possible rustiness.
