Rating favorite - chess term
Rating favorite
Definition
A rating favorite is the player whose Elo or online rating suggests a higher expected score against a specific opponent. In chess commentary, pairings, and previews, “the rating favorite” is the competitor statistically more likely to score better in a game or match based on the rating gap. Synonyms include “rating favourite” (UK) and “higher seed.”
At-a-glance facts
- The Elo expected score model estimates a favorite’s game outcome: Expected score = 1 / (1 + 10^(-ΔR/400)), where ΔR = favorite’s rating − opponent’s rating.
- Being the rating favorite does not guarantee a win; it’s a probabilistic label, not a prediction for a single game.
- Time controls matter: a Classical rating favorite isn’t always the favorite in Blitz or Bullet.
- Context matters: openings, match format, color assignment, and psychological factors can shift practical chances even when ratings suggest otherwise.
How the term is used in chess
Usage in tournaments and broadcasts
In Swiss events, the higher-rated player is often called the “rating favorite” on each board, especially in early rounds where pairings pit top seeds against lower-rated players. In round robins and matches, previews will mark the overall rating favorite for the event as well as the rating favorite per game, accounting for color (White usually has a small advantage).
- Swiss round example: A 2700 vs 2350 pairing makes the 2700 the clear rating favorite.
- Match play: A 25–50 Elo edge suggests a modest favorite; 100–200 Elo indicates a strong favorite.
- Online arenas: Streamers and commentators frequently reference the rating favorite in Blitz/Bullet, where volatility is higher and “Upset”s are common.
Media and analytics will also reference rating favorites when discussing “draw odds,” tiebreak expectations, or “must-win” scenarios (e.g., an underdog needing to complicate).
Strategic and psychological significance
When you are the rating favorite
- Game strategy: Favor sound, low-risk positions that keep control and avoid unnecessary weaknesses; prioritize “two results” (win/draw) positions.
- Opening choices: Lean on solid, well-rehearsed “Book” lines that minimize tactical roulette; think Berlin, Petroff, or solid Queen’s Gambit structures.
- Risk management: Avoid “speculative sacrifice” unless justified; play to squeeze small edges and convert endgames with technique.
When you face the rating favorite
- Practical chances: Increase complexity, unbalance material/structure, and seek dynamic play where technique alone won’t decide.
- Psychology: Favorites often feel pressure to win; resourceful defense and counterplay can create “Swindle” opportunities.
- Time controls: In Blitz/Bullet, even a large rating edge can evaporate under Zeitnot and “Flag” risk.
Examples and mini-cases
Historic matches and events
- Fischer vs. Spassky, 1972: Fischer was the rating favorite and won the title, validating the Elo edge over the match distance.
- Kasparov vs. Deep Blue, 1997: Kasparov entered as the human rating favorite but lost the match—an iconic upset in chess and AI history.
- Kasparov vs. Kramnik, World Championship 2000: Kasparov was widely viewed as the pre-match favorite by rating and reputation; Kramnik won by superb preparation and match strategy.
- Carlsen vs. Karjakin, World Championship 2016: Carlsen was a clear rating favorite, yet he required tiebreaks to clinch the title—proof that single-game variance and match dynamics matter.
Round example with expected score
Suppose White is 2600 and Black is 2450 (ΔR = 150). Expected score for White ≈ 1 / (1 + 10^(-150/400)) ≈ 0.70. That is, the rating favorite “should” score about 70% across many such games—roughly 7 out of 10—though any single game can deviate.
Position snippet: a favorite’s solid approach
A rating favorite with Black might choose the Berlin Defense to reduce risk and play a technically sound endgame:
Moves: 1. e4 e5 2. Nf3 Nc6 3. Bb5 Nf6 4. O-O Nxe4 5. d4 Nd6 6. Bxc6 dxc6 7. dxe5 Nf5 8. Qxd8+ Kxd8 — leading to the famous “Berlin endgame,” known for solidity and drawing resources.

Math corner: Elo and expected score
Using the Elo model, the favorite’s expected score E = 1 / (1 + 10^(−ΔR/400)). Common gaps:
- ΔR = 0 → E = 0.50 (even)
- ΔR ≈ 100 → E ≈ 0.64
- ΔR ≈ 200 → E ≈ 0.76
- ΔR ≈ 300 → E ≈ 0.85
- ΔR ≈ 400 → E ≈ 0.91
Remember: these are long-run averages, not guarantees for one game. Differences by time control are real; a player can be a rating favorite in Classical but not in Blitz/Bullet.

Online chess angle (Blitz, Bullet, Rapid)
In fast controls, practical factors (premoves, mouse speed, and clock handling) amplify variance. A classical rating favorite may not be the favorite in Bullet if the opponent is a “Bullet” specialist or notorious “Flagging” expert. Increment and delay change the dynamics; without increment, even the stronger side can get “Flagged.”
- Bullet-specific edges: fast tactics, pre-move mastery, sharp openings, and conversion speed.
- Blitz-specific edges: opening depth, pattern recognition, and “Practical chances” exploitation.

Interesting facts and anecdotes
- Ratings predict scores better over many games than in single encounters; this is why long matches tend to favor rating favorites.
- Many famous “immortals” are upsets against a rating favorite; strong preparation, surprise “TN”s (theoretical novelties), and nerve can overturn expectations.
- Opening selection is part of expectation management: favorites often choose “book-draw-ish” lines with Black to maintain match leads, and press with White.
Common misconceptions
- “The rating favorite will win today.” False. Elo provides probabilities, not certainties.
- “Ratings are identical across time controls.” False. A Blitz or Bullet specialist can flip who is the favorite.
- “Being favorite means playing recklessly for a win.” Usually wrong; favorites tend to manage risk and convert small advantages rather than overpress.
Practical checklist
- If you are the rating favorite: pick reliable “Book” lines, value king safety, avoid unnecessary complications, and be ready to cash out to a “Perpetual” or “Book draw” if the match situation favors it.
- If you are the underdog: seek imbalance, create multiple threats, keep “Swindling chances” alive, and play for the initiative and complications.
- Always factor color, form, and time control; don’t rely on a single rating number.
