Circadian Optimization Survey

Mapping individual chronotype alignments against peak calculation speed and vulnerability to tactical blunders.

1. Self-Identified Chronotype

What is your natural biological sleep-wake cycle?

Morning Lark (Naturally wake up early, peak alertness before noon) Night Owl (Naturally sleep late, peak alertness late evening/night) Biphasic / Flexible (Afternoon napper, adaptable)

2. The "Grandmaster" Window

During which specific hour block do you feel your tactical vision is absolute, sharp, and effortless?

3. Chrono-Blunder Vulnerability

Statistically, when do your most uncharacteristic, obvious 1-move blunders occur?

4. Pre-Tournament Sleep Architecture

How does competitive anxiety affect your sleep the night before a major over-the-board match?

Severe insomnia/disruption. I rarely sleep well before a game. Mild disruption, but I manage 5-6 hours. No impact. I sleep my standard 7-8 hours.

5. Caffeine & Stimulant Reliance

How reliant are you on stimulants (coffee, energy drinks) to artificially force your brain into peak calculation mode during off-hours?

6. Time Control vs Biological Clock

Detail how asynchronous time controls (e.g., fast Bullet vs slow Classical) are affected by your biological fatigue. Can you play Bullet while tired but not Classical, or vice versa?
