2. Next 3 months (2,400 games):
   • Intermediate improvement, deeper understanding of strategy, more refined tactics, and possibly some initial coaching.
   • Likely rating: 1400-1600 Elo.
3. Final 5 months (4,000 games):
   • Advanced play, regular study of openings, endgames, tactics, and perhaps serious coaching.
   • Competing against stronger opponents, learning from losses, and refining skills.
   • Likely rating: 1800-2000 Elo.

Given the intense number of games and Tyler1's dedication, it's reasonable to assume significant progress. A precise estimate of his rating after 10 months and 8,000 games would be:
