➤ Key Insights
- Time handicap effectiveness: Despite a ~600 Elo strength gap, the 90x time advantage allowed Rybka to win 62% of games
- Stockfish's resilience: Even with only 2 seconds starting time, SF18 still won 25% of games
- Draw rate: 26% draw rate shows competitive balance despite vastly different time controls
- Elo performance: Rybka performed at 2429 Elo (below baseline), Stockfish at 2383 (above baseline given time handicap)
- GUI impact: Chess Arena's time management likely contributed to Stockfish timeouts
Experiment demonstrates that extreme time handicaps can partially compensate for substantial strength differences in chess engines
