10 Possible Future Scenarios in Chess Rankings and Championships

Magnus Carlsen Maintains His Dominance Until 2029

Magnus Carlsen continues to exhibit exceptional skill and consistency in classical chess tournaments, retaining his #1 ranking through 2029. His deep understanding of the game, strategic versatility, and psychological fortitude prevent any significant decline in his performance. Carlsen participates actively in major tournaments, consistently securing top positions and accumulating ranking points that solidify his position at the apex of the chess world.
Arjun Erigaisi Ascends to World #1 by 2027

Arjun Erigaisi experiences a meteoric rise in the chess rankings, thanks to innovative strategies and relentless training. By 2027, his performance in elite tournaments surpasses that of Magnus Carlsen, earning him the coveted #1 spot. Erigaisi's deep preparation and adaptability to different playing styles allow him to outmaneuver established players, marking the emergence of a new dominant force in chess.
Fabiano Caruana Reclaims the Top Spot by 2026

Fabiano Caruana undergoes a significant resurgence in his chess career, refining his techniques and strategies. His enhanced focus and consistent tournament victories propel him to the #1 ranking by 2026. Caruana's experience and profound understanding of classical chess enable him to navigate complex positions effectively, reclaiming his position at the pinnacle of the chess hierarchy.
Magnus Carlsen Steps Back from Classical Chess in 2027

In a strategic move, Magnus Carlsen decides to reduce his participation in classical chess tournaments to focus more on rapid and blitz formats. This decision leads to a gradual decline in his classical chess ranking as other players seize the opportunity to ascend. By 2029, Carlsen steps away from the #1 classical ranking, allowing emerging talents like Arjun Erigaisi and Fabiano Caruana to vie for the top position.
A New Generation of Players Dominates the Chess Scene by 2030

A fresh wave of young and talented players enters the chess arena, bringing innovative approaches and heightened competitiveness. These new challengers, possibly in their late teens or early twenties, rapidly improve and begin to dominate major tournaments. By 2030, players outside the current top tier, such as emerging talents from diverse backgrounds, disrupt the established rankings, preventing any single player from maintaining prolonged dominance.
Magnus Carlsen Focuses Solely on Rapid and Blitz Chess

Magnus Carlsen shifts his attention exclusively to faster-paced formats like rapid and blitz chess, leaving classical chess rankings more open to competition. This strategic focus allows him to excel in quicker time controls, but his reduced participation in classical events leads to a drop in his classical world ranking. Consequently, players like Arjun Erigaisi and Fabiano Caruana have the opportunity to ascend to the #1 spot in classical chess by 2029.
Arjun Erigaisi and Fabiano Caruana Engage in a Close Competition for #1

Both Arjun Erigaisi and Fabiano Caruana experience simultaneous growth in their chess careers, leading to a fierce competition for the top ranking. Their performances in major tournaments fluctuate, with each player taking turns in leading the rankings. By 2029, neither has definitively secured the #1 spot, resulting in a dynamic and closely contested top tier that showcases the high level of competition.
Magnus Carlsen Reclaims the FIDE World Chess Championship by 2031

After a period of reduced participation in classical chess, Magnus Carlsen mounts a strong comeback, culminating in a decisive victory at the FIDE World Chess Championship in 2031. His experience, strategic depth, and determination allow him to overcome newer and younger challengers, reaffirming his status as one of the greatest chess players of all time.
Advancements in Chess AI Propel New Players to the Top

Innovations in chess training, particularly the use of advanced AI tools, enable younger players like Arjun Erigaisi to enhance their gameplay significantly. These AI-assisted training methods facilitate rapid learning and strategic innovation, allowing players to analyze and execute complex positions with unprecedented precision. By 2028, such advancements contribute to players like Erigaisi surpassing Magnus Carlsen in the rankings.
Magnus Carlsen Remains #1 and Wins the FIDE Championship by 2031

Combining sustained high performance with strategic participation in key tournaments, Magnus Carlsen not only retains his #1 ranking through 2029 but also triumphs at the FIDE World Chess Championship in 2031. His continuous dedication to the game, adaptability to evolving playing styles, and psychological resilience ensure his dominance and championship success over the next decade.

Squiggle Language Model for Future Chess Rankings and Championships

The following Squiggle model encapsulates the probabilities and scenarios outlined above, providing a probabilistic framework for predicting future outcomes in chess rankings and championships.


// Define base probabilities for key outcomes
carlsen_stays_top_2029 = beta(7, 3) // Probability Magnus Carlsen remains #1 in 2029
erigaisi_becomes_top = beta(4, 6) // Probability Arjun Erigaisi becomes #1
caruana_becomes_top = beta(5, 5) // Probability Fabiano Caruana becomes #1
carlsen_fide_champ_2031 = beta(6, 4) // Probability Magnus Carlsen becomes FIDE World Champion by 2031

// Define yearly decay factors for Magnus Carlsen's dominance
yearly_decay_carlsen = 0.95 to 0.98 // Annual probability of maintaining dominance

// Define growth factors for Arjun Erigaisi and Fabiano Caruana
yearly_growth_erigaisi = 1.05 to 1.10 // Annual improvement factor for Arjun
yearly_growth_caruana = 1.03 to 1.07 // Annual improvement factor for Fabiano

// Calculate probabilities over time
carlsen_rank_2029 = carlsen_stays_top_2029 * (yearly_decay_carlsen ^ (2029 - 2025))
erigaisi_rank_2029 = erigaisi_becomes_top * (yearly_growth_erigaisi ^ (2029 - 2025))
caruana_rank_2029 = caruana_becomes_top * (yearly_growth_caruana ^ (2029 - 2025))
carlsen_champ_2031 = carlsen_fide_champ_2031 * (yearly_decay_carlsen ^ (2031 - 2025))

// Output the probabilities
{
  carlsen_rank_2029: carlsen_rank_2029,
  erigaisi_rank_2029: erigaisi_rank_2029,
  caruana_rank_2029: caruana_rank_2029,
  carlsen_champ_2031: carlsen_champ_2031
}

Detailed Breakdown of the Squiggle Model

Variable	Description	Probability Range
carlsen_stays_top_2029	Probability Magnus Carlsen remains #1 in 2029	Beta(7, 3)
erigaisi_becomes_top	Probability Arjun Erigaisi becomes #1	Beta(4, 6)
caruana_becomes_top	Probability Fabiano Caruana becomes #1	Beta(5, 5)
carlsen_fide_champ_2031	Probability Magnus Carlsen becomes FIDE World Champion by 2031	Beta(6, 4)
yearly_decay_carlsen	Annual probability of Magnus Carlsen maintaining dominance	0.95 to 0.98
yearly_growth_erigaisi	Annual improvement factor for Arjun Erigaisi	1.05 to 1.10
yearly_growth_caruana	Annual improvement factor for Fabiano Caruana	1.03 to 1.07

Scenario Implementation

The model calculates the likelihood of each scenario by considering the base probabilities and adjusting them based on yearly decay or growth factors. This provides a dynamic representation of how each player's probability evolves over time.

Example Calculation

To determine the probability of Magnus Carlsen remaining the top-ranked player in 2029:


// Calculate Magnus Carlsen's ranking probability in 2029
carlsen_rank_2029 = carlsen_stays_top_2029 * (yearly_decay_carlsen ^ (2029 - 2025))

This calculation accounts for the annual decay in Carlsen's dominance, reflecting the natural fluctuations in performance over the four-year span.

Conclusion

The future of chess rankings and championships hinges on a myriad of factors, including individual player performance, strategic decisions, and evolving competitive dynamics. Magnus Carlsen's sustained excellence presents a strong case for his continued dominance, while the emergence of Arjun Erigaisi and Fabiano Caruana introduces exciting possibilities for shifts in the top rankings. The Squiggle model provides a probabilistic framework to assess these potential outcomes, highlighting the inherent uncertainties and the multifaceted nature of competitive chess.
